Description

本発明は、室内の空気を冷暖する空気調和機の室外機に関する。 The present invention relates to an outdoor unit of an air conditioner that cools and warms indoor air.

オフィスや工場などの室内空気を冷暖する空気調和機は、室内に配設される室内機と、屋外に配設される室外機を備えている。室外機は、筐体の側面部に周設された熱交換器内の冷媒を外気の温度で蒸発又は凝縮させた後に室内機に供給し、室内機は、室外機から供給される冷媒の潜熱を利用して室内空気を冷暖する。 BACKGROUND ART An air conditioner that cools and warms indoor air in an office or a factory includes an indoor unit that is disposed indoors and an outdoor unit that is disposed outdoors. The outdoor unit evaporates or condenses the refrigerant in the heat exchanger provided around the side surface of the housing at the temperature of the outside air and then supplies the refrigerant to the indoor unit. The indoor unit supplies the latent heat of the refrigerant supplied from the outdoor unit. Use to cool and warm the room air.

このような空気調和機においては、比較的大きな空調能力が求められる場合、複数の室外機を接続したマルチパッケージエアコン用の室外機を構成することがある。室外機を複数設置する形態としては、複数の室外機を据付現場で連接させるいわゆる外付けモジュール式があるが、その方式では、現地での据付作業等が煩雑になる。そこで、据付作業等を簡単にする観点から、据付現場に搬入する前に、予め複数の室外機を互いに隣接させた一体型のマルチパッケージエアコン用の室外機を構成することが行われる。 In such an air conditioner, when a relatively large air conditioning capability is required, an outdoor unit for a multi-package air conditioner in which a plurality of outdoor units are connected may be configured. As a form of installing a plurality of outdoor units, there is a so-called external module type in which a plurality of outdoor units are connected at the installation site, but this method complicates installation work on the site. Therefore, from the viewpoint of simplifying the installation work and the like, before carrying in the installation site, an outdoor unit for an integrated multi-package air conditioner in which a plurality of outdoor units are adjacent to each other in advance is configured.

このように複数の室外機を一体型に構成する場合、隣接する室外機間を接続する配管が必要になる。その接続配管を側面部に配設しようとすると、接続配管が熱交換器に遮られることがある。そこで、配管用スペースを確保するためには、熱交換器の周設位置を筐体の背面の全部と両側面の半分以下の部分に制限することが行われる（例えば、特許文献１）。 In this way, when a plurality of outdoor units are configured as an integral type, piping for connecting adjacent outdoor units is required. When it is going to arrange | position the connection piping in a side part, a connection piping may be interrupted | blocked by the heat exchanger. Therefore, in order to secure a space for piping, the circumferential position of the heat exchanger is limited to the entire back surface of the housing and to a portion of half or less of both side surfaces (for example, Patent Document 1).

特開２００３−２５４５６５号（第１図）Japanese Patent Laid-Open No. 2003-254565 (FIG. 1)

しかし、特許文献１のように、熱交換器の周設位置を制限して熱交換器の周長を縮減させた場合、室外機の据付け面積を増大させずに所定の熱交換面積を確保するには、その高さ寸法を増大させる必要があるなど、室外機の大型化を招くことになる。また、熱交換器の周長の縮減に起因する損失を補填するために、補助熱交換器を別部品として配設すると、部品点数の増大及び配管系統の煩雑化を招くという問題がある。 However, as in Patent Document 1, when the circumferential position of the heat exchanger is limited and the circumference of the heat exchanger is reduced, a predetermined heat exchange area is secured without increasing the installation area of the outdoor unit. Therefore, it is necessary to increase the height dimension of the outdoor unit, which increases the size of the outdoor unit. In addition, if the auxiliary heat exchanger is provided as a separate part in order to compensate for the loss due to the reduction in the circumference of the heat exchanger, there is a problem that the number of parts increases and the piping system becomes complicated.

本発明の課題は、所定の熱交換面積を確保しつつ、装置の大型化を抑えるのにより好適な一体型マルチパッケージエアコン用の室外機を実現することにある。 An object of the present invention is to realize an outdoor unit for an integrated multi-package air conditioner that is more suitable for suppressing an increase in size of the apparatus while ensuring a predetermined heat exchange area.

上記課題を解決するために、本発明の空調用室外機は、筐体と、該筐体の側面部に周設された熱交換器と、前記筐体の頂部に形成された空気の排出口に臨んで配設された送風機と、前記筐体の裾部に設けられる底板部とを備え、前記底板部は、機器類が載置される配置面と、該配置面の周縁部から前記筐体側に隆起して前記熱交換器の下縁部を支える台座部とを有し、該台座部に配管用穴が形成されてなることを特徴とする。 In order to solve the above-mentioned problems, an outdoor unit for air conditioning according to the present invention includes a housing, a heat exchanger that is provided around the side surface of the housing, and an air outlet formed at the top of the housing. And a bottom plate provided at the bottom of the housing, the bottom plate having a placement surface on which devices are placed and a peripheral portion of the placement surface from the casing. And a pedestal portion that protrudes toward the body side and supports the lower edge of the heat exchanger, and a hole for piping is formed in the pedestal portion.

これによれば、複数の室外機を接続して一体型のマルチパッケージエアコン用の室外機を構成する際、各室外機の配管用穴に接続配管を這わすことができる。ここで熱交換器は、配管用穴が形成された台座部の上に着座される。すなわち、接続配管の配設位置は、熱交換器の配設位置に左右されないので、接続配管を配設するに際し、熱交換器の周長を制限せずに済む。その結果、限られた設置面積で熱交換器の周長を最大限に確保できるから、所定の熱交換面積を確保しつつ、装置の高さ又は据付面積の増大を抑えることができる。 According to this, when a plurality of outdoor units are connected to form an outdoor unit for an integrated multi-package air conditioner, the connecting pipe can be passed through the piping hole of each outdoor unit. Here, the heat exchanger is seated on a pedestal portion in which a hole for piping is formed. That is, the arrangement position of the connection pipe does not depend on the arrangement position of the heat exchanger, and therefore, it is not necessary to limit the circumference of the heat exchanger when arranging the connection pipe. As a result, the perimeter of the heat exchanger can be secured to the maximum with a limited installation area, so that an increase in the height or installation area of the apparatus can be suppressed while ensuring a predetermined heat exchange area.

この場合において、配管用穴は、前記台座部の一部を切り欠いて形成することができる。 In this case, the piping hole can be formed by cutting out a part of the pedestal portion.

また、熱交換器は台座部に載置されるが、機器類（例えば圧縮機）は配置面に載置される。すなわち、熱交換器は、機器類よりも一段高い位置に配設される。これにより、熱交換器を通気して筐体内に流入した空気が排出口から排出されるまでの過程で、その空気流が機器類に衝突することを低減できるので、圧力損失を減らすことができる。 Moreover, although a heat exchanger is mounted in a base part, apparatuses (for example, compressor) are mounted in the arrangement | positioning surface. That is, the heat exchanger is disposed at a position one level higher than the devices. As a result, it is possible to reduce the air flow from colliding with the equipment in the process until the air flowing through the heat exchanger and flowing into the housing is discharged from the discharge port, so that pressure loss can be reduced. .

また、本発明の空気調和機は、前記底板部は、前記台座部の一部を切り欠いて前記配管用穴が形成されてなることを特徴とする。 In the air conditioner of the present invention, the bottom plate portion is formed by cutting out a part of the pedestal portion to form the piping hole.

また、本発明の空調用室外機の底板は、機器類が載置される配置面と、該配置面の周縁部から隆起して熱交換器の下縁部を支える台座部とを有し、該台座部に配管用穴が形成されてなることを特徴とする。 Further, the bottom plate of the outdoor unit for air conditioning of the present invention has an arrangement surface on which devices are placed, and a pedestal portion that protrudes from the peripheral portion of the arrangement surface and supports the lower edge of the heat exchanger, A piping hole is formed in the pedestal portion.

本発明によれば、所定の熱交換面積を確保しつつ、装置の大型化を抑えるのにより好適な一体型マルチパッケージエアコン用の室外機を実現できる。 ADVANTAGE OF THE INVENTION According to this invention, the outdoor unit for integrated multi-package air conditioners more suitable for suppressing the enlargement of an apparatus is ensured, ensuring a predetermined heat exchange area.

（第一の実施形態）
本発明を適用した空調用室外機及び空気調和機の第一の実施形態について図面を参照して説明する。図１は、本実施形態の室外機の構成を示す縦断面図である。図２は、図１の室外機を排出口側から見た上面図である。図３は、図１の底板部を示す斜視図である。 (First embodiment)
A first embodiment of an air conditioning outdoor unit and an air conditioner to which the present invention is applied will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing the configuration of the outdoor unit of the present embodiment. FIG. 2 is a top view of the outdoor unit in FIG. 1 as viewed from the outlet side. FIG. 3 is a perspective view showing the bottom plate portion of FIG.

図１に示すように、ビルの屋上などに配設される空調用の室外機１０は、側面部から外気を吸込んで上方に排出する上吹き型に構成されている。より具体的には、室外機１０は、筐体１２の側面部に周設された熱交換器１４と、筐体１２の頂部に形成された空気の排出口１６に臨んで配設された送風機としての軸流ファン１８と、筐体１２の裾部に設けられる底板部２０などを備えている。 As shown in FIG. 1, an air conditioner outdoor unit 10 disposed on a rooftop of a building is configured as an upper blowing type that sucks outside air from a side surface and discharges it upward. More specifically, the outdoor unit 10 includes a heat exchanger 14 that is provided around the side surface of the housing 12 and an air blower that faces the air discharge port 16 formed at the top of the housing 12. As the axial fan 18 and the bottom plate 20 provided at the bottom of the housing 12.

ここで、本実施形態の室外機１０に適用される底板部２０は、圧縮機２１などの冷凍サイクル部品が載置される配置面２２と、配置面２２の周縁部から筐体１２側に隆起して熱交換器１４の下縁部を支える台座部としての段差部２４を有している。そして、図３に示すように、底板部２０は、配置面２２に対して平行な方向に段差部２４を貫通する配管用穴２６が形成されている。ここでの配管用穴２６は、段差部２４の一部を切り欠いて形成されている。 Here, the bottom plate portion 20 applied to the outdoor unit 10 of the present embodiment protrudes from the arrangement surface 22 on which a refrigeration cycle component such as the compressor 21 is placed, and the peripheral portion of the arrangement surface 22 toward the housing 12. Thus, it has a step 24 as a pedestal that supports the lower edge of the heat exchanger 14. As shown in FIG. 3, the bottom plate portion 20 has a piping hole 26 that penetrates the step portion 24 in a direction parallel to the arrangement surface 22. The piping hole 26 here is formed by cutting out a part of the stepped portion 24.

より詳細に室外機１０について説明する。図１に示すように、筐体１２は、４つの側面で区画形成された本体部１２ａと、本体部１２ａの上部に配設された筒状の風洞１２ｂを有している。説明の便宜上、本体部１２ａの４つの側面のうち、紙面右側の側面を背面２８と称し、背面２８に対向する側面を正面３０と称し、正面３０及び背面２８に隣接する側面を横面３１、３３と称する。背面２８及び横面３１、３３は、空気の吸込面として例えば吸込グリルが取り付けられている。正面３０は、電気品を収納する電気品箱３５などの機器のメンテナンス用のカバーが着脱可能にはめ込まれている。 The outdoor unit 10 will be described in more detail. As shown in FIG. 1, the housing 12 has a main body portion 12 a defined by four side surfaces, and a cylindrical wind tunnel 12 b disposed on the upper portion of the main body portion 12 a. For convenience of explanation, of the four side surfaces of the main body 12a, the right side surface of the paper surface is referred to as the back surface 28, the side surface facing the back surface 28 is referred to as the front surface 30, and the side surfaces adjacent to the front surface 30 and the back surface 28 are the lateral surfaces 31, 33. For example, a suction grill is attached to the back surface 28 and the lateral surfaces 31 and 33 as an air suction surface. The front 30 is fitted with a cover for maintenance of equipment such as an electrical product box 35 for storing electrical products in a detachable manner.

風洞１２ｂは、空気の排出口１６としての開口を頂部に有し、軸流ファン１８が内部に配設されている。軸流ファン１８は、本体部１２ａの上部に配設された支持部材を介して風洞１２ｂに同軸に設けられたファンモータ３２に取り付けられている。このファンモータ３２の駆動に連動して軸流ファン１８が回転すると、筐体１２の背面２８及び横面３１、３３の吸込面から外気が吸込まれ、吸込まれた外気が熱交換器１４の表面を通気した後に排出口１６から排出される。 The wind tunnel 12b has an opening as an air discharge port 16 at the top, and an axial fan 18 is disposed inside. The axial fan 18 is attached to a fan motor 32 provided coaxially in the wind tunnel 12b via a support member disposed on the upper portion of the main body 12a. When the axial fan 18 rotates in conjunction with the drive of the fan motor 32, outside air is sucked from the suction surfaces of the back surface 28 and the lateral surfaces 31 and 33 of the housing 12, and the sucked outside air is the surface of the heat exchanger 14. After being ventilated, the air is discharged from the discharge port 16.

熱交換器１４は、内部流路を通流する冷媒を外気の温度で蒸発又は凝縮させるものである。この熱交換器１４は、空気が通気可能に例えば熱交換管が列段積みして構成されており、筐体１２の外淵に沿って配設されている。より具体的には、図２に示すように、熱交換器１４は、横断面において背面２８側から正面３０側に向かうにつれて幅が広がったハの字形に形成されている。このような形状の熱交換器１４は、背面２８の空気吸込面に沿って配設されるとともに、横面３１及び横面３３の背面２８側から少なくとも４分の３以上を占める空気吸込面に沿って配設されている。 The heat exchanger 14 evaporates or condenses the refrigerant flowing through the internal flow path at the temperature of the outside air. The heat exchanger 14 is configured by stacking, for example, heat exchange tubes in a row so that air can be vented, and is disposed along the outer casing of the housing 12. More specifically, as shown in FIG. 2, the heat exchanger 14 is formed in a square shape having a width that increases from the back surface 28 side to the front surface 30 side in the cross section. The heat exchanger 14 having such a shape is disposed along the air suction surface of the back surface 28 and has an air suction surface that occupies at least three-fourths from the back surface 28 side of the lateral surface 31 and the lateral surface 33. It is arranged along.

そして、本実施形態の底板部２０は、図３に示すように、圧縮機２１などの冷凍サイクル部品が載置される配置面２２と、配置面２２の周縁部から筐体１２側に突起した段差部２４と、配置面２２の周側辺から下方に突出して形成された装置固定用の脚部４０を備えている。 And the baseplate part 20 of this embodiment protruded to the housing | casing 12 side from the arrangement | positioning surface 22 in which refrigeration cycle components, such as the compressor 21, are mounted, and the peripheral part of the arrangement | positioning surface 22, as shown in FIG. A stepped portion 24 and a device fixing leg 40 formed to protrude downward from the peripheral side of the arrangement surface 22 are provided.

段差部２４は、熱交換器１４の下縁部が着座可能に平坦に形成された座面４２を隆起先端側に有している。すなわち、座面４２は、配置面２２よりも一段高い位置に形成されている。また、段差部２４は、筐体１２の横面３１、３３に対応する辺部のほぼ中央に陥没部４４が形成されている。本形態の陥没部４４は、座面４２を切り欠いて形成されている。なお、陥没部４４は、段差部２４の各辺部のそれぞれに１つずつ形成されているが、各辺部に複数形成してもよい。 The stepped portion 24 has a seating surface 42 formed flat so that the lower edge portion of the heat exchanger 14 can be seated on the protruding tip side. That is, the seat surface 42 is formed at a position one step higher than the arrangement surface 22. In addition, the stepped portion 24 has a recessed portion 44 formed substantially at the center of the side portion corresponding to the lateral surfaces 31 and 33 of the housing 12. The depressed portion 44 in this embodiment is formed by cutting out the seating surface 42. One depressed portion 44 is formed on each side portion of the stepped portion 24, but a plurality of depressed portions 44 may be formed on each side portion.

このような段差部２４の座面４２に熱交換器１４を載置した際、熱交換器１４の下縁部と陥没部４４との間で形成される空間が配管用穴２６となる。また、配管用穴２６の形状に対応して形成された塞ぎ板４６が陥没部４４に着脱可能にはめ込まれる。この塞ぎ板４６は、外気の流入を防ぐものであり、配管用穴２６に接続配管を這わせるときなどの必要に応じて取り外される。なお、段差部２４は、筐体１２の正面３０に対応する辺部のほぼ中央にメンテナンス用の開口が形成されている。 When the heat exchanger 14 is placed on the seating surface 42 of the stepped portion 24, a space formed between the lower edge portion of the heat exchanger 14 and the recessed portion 44 becomes the piping hole 26. Further, a closing plate 46 formed corresponding to the shape of the piping hole 26 is detachably fitted into the depressed portion 44. The closing plate 46 prevents inflow of outside air, and is removed when necessary, for example, when connecting piping is put in the piping hole 26. The step portion 24 has a maintenance opening formed substantially at the center of the side portion corresponding to the front surface 30 of the housing 12.

脚部４０は、下部周縁に形成されたつば部４７を有し、つば部４７に製品固定用穴４８が形成されている。室外機１０を据付け現場に固定する際は、製品固定用穴４８を介してアンカーボルトなどで現場に固定する。また、脚部４０は、水平方向に貫通されたフォークリフト運搬用の穴５０が形成されている。 The leg portion 40 has a flange portion 47 formed on the lower peripheral edge, and a product fixing hole 48 is formed in the flange portion 47. When the outdoor unit 10 is fixed to the installation site, the outdoor unit 10 is fixed to the site with an anchor bolt or the like through the product fixing hole 48. Further, the leg portion 40 is formed with a hole 50 for carrying a forklift that is penetrated in the horizontal direction.

図４は、複数の室外機１０ａ、１０ｂを接続した一体型のマルチパッケージエアコン用の室外機を示す構成図である。ここでの室外機１０ａ、１０ｂは、マルチパッケージエアコン用の室外機を構成するための基本モジュールであり、図１の形態と基本的に同様である。したがって、図１と相互に対応する箇所に同一符号を付する。 FIG. 4 is a configuration diagram showing an outdoor unit for an integrated multi-package air conditioner in which a plurality of outdoor units 10a and 10b are connected. The outdoor units 10a and 10b here are basic modules for configuring an outdoor unit for a multi-package air conditioner, and are basically the same as the configuration in FIG. Therefore, the same code | symbol is attached | subjected to the location mutually corresponding to FIG.

図４に示すように、マルチパッケージエアコン用の室外機は、複数の室外機１０ａ、１０ｂが互いに隣接して複数配列されている。そして、室外機１０ａの配管用穴２６が室外機１０ｂの配管用穴２６に連通して形成されている。換言すると、室外機１０ａの配管用穴２６の位置は、室外機１０ｂの配管用穴２６の位置に合わせられている。このような配管用穴２６を介して冷媒通流用の接続配管５２が配設されることになる。 As shown in FIG. 4, in the outdoor unit for a multi-package air conditioner, a plurality of outdoor units 10a and 10b are arranged adjacent to each other. And the piping hole 26 of the outdoor unit 10a is formed in communication with the piping hole 26 of the outdoor unit 10b. In other words, the position of the piping hole 26 of the outdoor unit 10a is adjusted to the position of the piping hole 26 of the outdoor unit 10b. The connecting pipe 52 for circulating the refrigerant is disposed through the pipe hole 26.

本実施形態によれば、複数の室外機（例えば、室外機１０ａ、室外機１０ｂ）を接続して一体型のマルチパッケージエアコン用の室外機を構成する際、各室外機１０ａ、１０ｂの配管用穴２６に接続配管５２を這わすことができる。ここで熱交換器１４は、配管用穴２６が形成された段差部２４の座面４２に載置される。すなわち、接続配管５２の配設位置は、熱交換器１４の配設位置に左右されないことから、接続配管５２を配設するに際し、熱交換器１４の周長を制限せずに済む。その結果、限られた設置面積で熱交換器１４の周長を最大限に確保できるから、所定の熱交換面積を確保しつつ、高さ又は据付面積の増大を抑えた一体型マルチパッケージエアコン用の室外機を実現できる。 According to this embodiment, when a plurality of outdoor units (for example, the outdoor unit 10a and the outdoor unit 10b) are connected to form an outdoor unit for an integrated multi-package air conditioner, the pipes for the outdoor units 10a and 10b are used. The connection pipe 52 can be passed through the hole 26. Here, the heat exchanger 14 is placed on the seating surface 42 of the step portion 24 in which the piping hole 26 is formed. In other words, the arrangement position of the connection pipe 52 does not depend on the arrangement position of the heat exchanger 14, and therefore the circumference of the heat exchanger 14 does not have to be restricted when the connection pipe 52 is arranged. As a result, since the circumference of the heat exchanger 14 can be secured to the maximum with a limited installation area, an increase in the height or installation area is suppressed while securing a predetermined heat exchange area. Can be realized.

図５は、本実施形態の室外機の高さを従前の室外機と比較した例を示すグラフである。ここでは据付面積と熱交換面積の双方を同じにした場合の室外機の高さを比較している。図５に示すように、従前の室外機の高さを基準にすると、本実施形態の室外機１０の高さは、従前よりも例えば１０％ほど抑えられている。すなわち、本実施形態によれば、熱交換器１４の伝熱面積を確保しつつ、室外機１０の高さや据付面積の増大を抑えることができる。その結果、省エネ性とコンパクト性を兼ね備えた空調用の室外機１０を実現できる。また、室外機１０の高さを抑えることにより、室外機１０の上部に防雪フードや風向ガイドを設けるのが容易になるし、室外機１０の搬入や運搬又は保管などが簡単になる。 FIG. 5 is a graph showing an example in which the height of the outdoor unit of the present embodiment is compared with a conventional outdoor unit. Here, the height of the outdoor unit is compared when both the installation area and the heat exchange area are the same. As shown in FIG. 5, when the height of the conventional outdoor unit is used as a reference, the height of the outdoor unit 10 of the present embodiment is suppressed by, for example, about 10% from the conventional level. That is, according to the present embodiment, it is possible to suppress an increase in the height and installation area of the outdoor unit 10 while securing the heat transfer area of the heat exchanger 14. As a result, the outdoor unit 10 for air conditioning having both energy saving and compactness can be realized. Moreover, by suppressing the height of the outdoor unit 10, it becomes easy to provide a snow hood and a wind direction guide on the upper part of the outdoor unit 10, and the carrying in, carrying, or storing of the outdoor unit 10 is simplified.

また、本実施形態によれば、熱交換器１４は段差部２４の座面４２に載置されるが、圧縮機２１などの冷凍サイクル部品は配置面２２に載置される。すなわち、熱交換器１４は、冷凍サイクル部品よりも一段高い位置に配設される。これにより、熱交換器１４を通気して筐体１２内に流入した空気が排出口１６から排出される過程で、その空気流が冷凍サイクル部品に衝突することを低減できるため、圧力損失を減らすことができる。 Further, according to the present embodiment, the heat exchanger 14 is placed on the seating surface 42 of the step portion 24, but the refrigeration cycle components such as the compressor 21 are placed on the arrangement surface 22. That is, the heat exchanger 14 is disposed at a position one step higher than the refrigeration cycle components. Thereby, in the process in which the air flowing through the heat exchanger 14 and flowing into the housing 12 is discharged from the discharge port 16, it is possible to reduce the collision of the air flow with the refrigeration cycle components, thereby reducing the pressure loss. be able to.

（第二の実施形態）
本発明を適用した空調用室外機及び空気調和機の第二の実施形態について図６及び図７を参照して説明する。本実施形態は、熱交換器の周長がより大きい点で第一の実施形態と異なる。したがって、第一の実施形態と相互に対応する箇所に同一符号を付し、相違点を中心に説明する。 (Second embodiment)
A second embodiment of an outdoor unit for air conditioning and an air conditioner to which the present invention is applied will be described with reference to FIGS. This embodiment is different from the first embodiment in that the circumference of the heat exchanger is larger. Therefore, the same code | symbol is attached | subjected to the location mutually corresponding with 1st embodiment, and it demonstrates centering around difference.

図６は、本実施形態の室外機の構成を正面側から見た図である。図７は、図６の室外機を排出口側からみた上面図である。図６及び図７に示すように、本実施形態の熱交換器６０は、筐体１２の側面部に周設される点で図２の形態と類似するが、図２の形態よりも配設周長が大きい。より具体的には、熱交換器６０は、背面２８及び横面３１、３３の全面に加えて、正面３０の一部にまで周長が延ばされている。ただし、正面３０の中央部は、圧縮機２１や電気品箱３５内の電気品のメンテナンス用として開口されている。換言すると、熱交換器６０は、横断面がロの字形に閉じた形態にされず、電気品箱３５を周方向に挟んだ形態で筐体１２の側壁部に周設されている。 FIG. 6 is a view of the configuration of the outdoor unit of the present embodiment as viewed from the front side. FIG. 7 is a top view of the outdoor unit in FIG. 6 as viewed from the outlet side. As shown in FIGS. 6 and 7, the heat exchanger 60 of the present embodiment is similar to the configuration of FIG. 2 in that it is provided around the side surface of the housing 12, but is arranged more than the configuration of FIG. 2. The circumference is large. More specifically, the heat exchanger 60 has a circumference extending to a part of the front surface 30 in addition to the entire surface of the back surface 28 and the lateral surfaces 31 and 33. However, the central portion of the front surface 30 is opened for maintenance of electrical products in the compressor 21 and the electrical product box 35. In other words, the heat exchanger 60 does not have a cross-sectional shape closed in a square shape, and is provided around the side wall portion of the housing 12 in a form in which the electrical component box 35 is sandwiched in the circumferential direction.

本実施形態によれば、圧縮機２１や電気品箱３５内の電気品のメンテナンス性を損なわずに、熱交換器６０の周長をより増大できるため、室外機１０の高さを更に低減できる。図５を参照すると、本実施形態の室外機１０の高さは、従前よりも例えば２０％、第一の実施形態よりも例えば１０％ほど抑えられている。すなわち、本実施形態によれば、熱交換器１４の伝熱面積をより確保しつつ、室外機１０の高さや据付面積の増大をより抑えることができる。その結果、省エネ性とコンパクト性を兼ね備えた空調用の室外機１０を実現できる。 According to the present embodiment, the peripheral length of the heat exchanger 60 can be further increased without impairing the maintainability of the electric appliances in the compressor 21 and the electric appliance box 35, so that the height of the outdoor unit 10 can be further reduced. . If FIG. 5 is referred, the height of the outdoor unit 10 of this embodiment will be suppressed about 20%, for example, about 10% rather than the first embodiment. That is, according to the present embodiment, it is possible to further suppress an increase in the height and installation area of the outdoor unit 10 while further ensuring the heat transfer area of the heat exchanger 14. As a result, the outdoor unit 10 for air conditioning having both energy saving and compactness can be realized.

（第三の実施形態）
本発明を適用した空調用室外機及び空気調和機の第三の実施形態について図８を参照して説明する。本実施形態は、段差部２４が配置面２２と樹脂系の材料で一体成形された点で第一の実施形態と異なる。したがって、第一の実施形態と相互に対応する箇所に同一符号を付し、相違点を中心に説明する。 (Third embodiment)
A third embodiment of an outdoor unit for air conditioning and an air conditioner to which the present invention is applied will be described with reference to FIG. This embodiment is different from the first embodiment in that the step portion 24 is integrally formed with the arrangement surface 22 and a resin material. Therefore, the same code | symbol is attached | subjected to the location mutually corresponding with 1st embodiment, and it demonstrates centering around difference.

図８は、本実施形態の底板部を示す斜視図である。図８に示す底板部２０は、段差部２４が配置面２２に樹脂系の材料で一体成形されている。また、配置面２２の周側辺のうち、正面３０に対応する辺部と背面２８に対応する辺部のそれぞれに脚部８０が別部品として設けられている。その脚部８０に製品固定用穴４８が形成されている。 FIG. 8 is a perspective view showing the bottom plate portion of the present embodiment. In the bottom plate portion 20 shown in FIG. 8, the step portion 24 is integrally formed on the arrangement surface 22 with a resin material. In addition, leg portions 80 are provided as separate parts on each of the side portion corresponding to the front surface 30 and the side portion corresponding to the back surface 28 of the peripheral side of the arrangement surface 22. A product fixing hole 48 is formed in the leg portion 80.

図８の本実施形態の底板部２０と比較するために、例えば、樹脂系材料に代えて板金で段差部と配置面を形成した場合を考えると、底板部の重力が大幅に増加する。しかも、段差部と配置面を板金の別部品として構成する場合は、製造工程が煩雑になるため所要コストが増大するし、段差部と配置面の結合強度（例えば水平方向の剛性）が低下する。また、段差部と配置面を板金のプレス成形等で一体成形する場合は、成形用の設備投資と金型制作費が必要になる。すなわち、段差部の配管用穴は、接続配管が数本配設されるのが一般的であるから、配線用穴を段差部に形成するには、段差部の高さを少なくとも数十ミリメートル以上にする必要がある。そのような段差部を板金プレス加工で成形するための設備や金型は大掛かりで煩雑なものになる。 In order to compare with the bottom plate portion 20 of the present embodiment in FIG. 8, for example, when considering the case where the stepped portion and the arrangement surface are formed of sheet metal instead of the resin-based material, the gravity of the bottom plate portion significantly increases. In addition, when the step portion and the arrangement surface are configured as separate parts of the sheet metal, the manufacturing process becomes complicated and the required cost increases, and the coupling strength (for example, horizontal rigidity) between the step portion and the arrangement surface decreases. . Further, when the stepped portion and the arrangement surface are integrally formed by sheet metal press molding or the like, capital investment for molding and mold production costs are required. That is, since the pipe for the step portion is generally provided with several connecting pipes, in order to form the wiring hole in the step portion, the height of the step portion is at least several tens of millimeters or more. It is necessary to. Equipment and molds for forming such a stepped portion by sheet metal pressing are large and complicated.

この点、本実施形態によれば、段差部２４と配置面２２を樹脂系の材料で成形することにより、第一の実施形態の効果に加えて、板金で構成した場合よりも重量を例えば三分の一以下に抑えることができる。また、段差部２４と配置面２２を一体成形することにより、底板部２０の部品点数が低減するし、製造工程が簡素化になるので、所要コストを低減できる。しかも、段差部２４と配置面２２の結合部の強度が増大するから、段差部２４と配置面２２を別部品として構成する場合よりも底板部２０の強度が向上する。 In this respect, according to the present embodiment, the step portion 24 and the arrangement surface 22 are formed of a resin-based material, so that, in addition to the effects of the first embodiment, the weight is, for example, three times higher than that of the case where the metal plate is configured. Can be kept to a fraction of a minute. Further, by integrally molding the step portion 24 and the arrangement surface 22, the number of parts of the bottom plate portion 20 is reduced and the manufacturing process is simplified, so that the required cost can be reduced. In addition, since the strength of the joint portion between the step portion 24 and the arrangement surface 22 is increased, the strength of the bottom plate portion 20 is improved as compared with the case where the step portion 24 and the arrangement surface 22 are configured as separate parts.

（第四の実施形態）
本発明を適用した空調用室外機及び空気調和機の第四の実施形態について図９及び図１０を参照して説明する。本実施形態は、底板部２０の配置面２２の裏側に補強部材としてのリブ９０が形成された点で第三の実施形態と異なる。したがって、第三の実施形態と相互に対応する箇所に同一符号を付し、相違点を中心に説明する。 (Fourth embodiment)
A fourth embodiment of an air conditioning outdoor unit and an air conditioner to which the present invention is applied will be described with reference to FIGS. 9 and 10. This embodiment differs from the third embodiment in that a rib 90 as a reinforcing member is formed on the back side of the arrangement surface 22 of the bottom plate portion 20. Therefore, the same code | symbol is attached | subjected to the location mutually corresponding to 3rd embodiment, and it demonstrates centering around difference.

図９は、本実施形態の底板部２０を裏側から見た図である。図９に示す底板部２０は、配置面２２に段差部２４及び脚部８０が樹脂系の材料で一体成形されている。この底板部２０は、配置面２２の裏側に複数のリブ９０が形成されている。より具体的には、リブ９０は、配置面２２に対して垂直に突起して形成されており、碁盤目状に配列されている。 FIG. 9 is a view of the bottom plate portion 20 of the present embodiment as viewed from the back side. In the bottom plate portion 20 shown in FIG. 9, the step portion 24 and the leg portion 80 are integrally formed on the arrangement surface 22 with a resin material. The bottom plate portion 20 has a plurality of ribs 90 formed on the back side of the arrangement surface 22. More specifically, the ribs 90 are formed so as to protrude perpendicular to the arrangement surface 22 and are arranged in a grid pattern.

本実施形態によれば、配置面２２の裏側にリブ９０が形成されているため、底板部２０の強度が向上する。すなわち、底板部２０は、熱交換器１４や圧縮機２１などの全ての冷凍サイクル部品を支えるに際し、重力方向に加わる力に対する剛性が向上するので、その力に起因する変形などを低減できる。また、底板部２０の水平方向の剛性も向上するから、室外機１０の運搬時、輸送時、運転時、地震発生時においても、水平方向に加わる力に起因する変形などを低減できる。 According to this embodiment, since the rib 90 is formed on the back side of the arrangement surface 22, the strength of the bottom plate portion 20 is improved. That is, when the bottom plate 20 supports all the refrigeration cycle components such as the heat exchanger 14 and the compressor 21, the rigidity against the force applied in the direction of gravity is improved, so that deformation caused by the force can be reduced. Further, since the horizontal rigidity of the bottom plate portion 20 is also improved, deformation caused by the force applied in the horizontal direction can be reduced even when the outdoor unit 10 is transported, transported, operated, or an earthquake occurs.

この場合において、リブ９０を形成するに際し、配置面２２に加えて脚部８０の内面にもリブ９０を延在して形成するのが望ましい。これにより、脚部８０の剛性が増大するから、底板部２０の強度が更に向上する。また、フォークリフト運搬用の穴５０にフォークリフトの腕が挿入された際のその腕の位置に対応してリブ９０を形成することが望ましい。これにより、フォークリフトで室外機１０を運搬するときの室外機１０の強度が向上する。 In this case, when the rib 90 is formed, it is desirable to extend the rib 90 on the inner surface of the leg 80 in addition to the arrangement surface 22. Thereby, since the rigidity of the leg part 80 increases, the intensity | strength of the baseplate part 20 further improves. In addition, it is desirable to form the rib 90 corresponding to the position of the arm when the forklift arm is inserted into the hole 50 for carrying the forklift. Thereby, the intensity | strength of the outdoor unit 10 when conveying the outdoor unit 10 with a forklift improves.

また、配置面２２に段差部２４及び脚部８０が一体成形されることから、配置面２２と段差部２４の結合強度や配置面２２と脚部８０の結合強度が増大して底板部２０の剛性が向上する。また、それら構成部を一体成形することにより、組立費や材料費などの所要コストを低減できる。すなわち、本実施形態の底板部２０を適用することにより、第１の実施形態の効果に加えて、軽量化と低コスト化を図りつつ強度を増大した室外機１０を実現できる。 Further, since the step portion 24 and the leg portion 80 are integrally formed on the arrangement surface 22, the coupling strength between the arrangement surface 22 and the step portion 24 and the coupling strength between the arrangement surface 22 and the leg portion 80 are increased, and the bottom plate portion 20. Stiffness is improved. Further, by integrally molding these components, required costs such as assembly costs and material costs can be reduced. That is, by applying the bottom plate portion 20 of the present embodiment, the outdoor unit 10 having increased strength while achieving weight reduction and cost reduction can be realized in addition to the effects of the first embodiment.

図１０は、本実施形態の底板部２０の剛性を従前の底板部と比較した例を示すグラフである。図１０の縦軸は底板部２０の重量と剛性を示す。また、横軸に示す従来Ａは、補強部材としての補助ステーが設けられていない従前の底板部である。従来Ｂは、補助ステーが設けられた従前の底板部である。ここでの従前の底板部とは、段差部と配置面を板金で別部品として形成したものである。なお、従来Ｂを比較の基準とする。 FIG. 10 is a graph showing an example in which the rigidity of the bottom plate portion 20 of the present embodiment is compared with a conventional bottom plate portion. The vertical axis in FIG. 10 indicates the weight and rigidity of the bottom plate portion 20. Further, Conventional A shown on the horizontal axis is a conventional bottom plate portion that is not provided with an auxiliary stay as a reinforcing member. Conventional B is a conventional bottom plate portion provided with an auxiliary stay. Here, the conventional bottom plate portion is formed by forming the step portion and the arrangement surface as separate parts using sheet metal. Conventional B is used as a reference for comparison.

図１０に示すように、本実施形態の底板部２０は、従来Ｂよりも重力方向の剛性が約２．５倍になるとともに、水平方向の剛性が約３倍になる。すなわち、配置面２２の裏側にリブ９０を形成することにより、板厚２〜３ｍｍ程度の薄肉でも十分な強度を確保できる。例えば、本実施形態の底板部２０は、従来Ｂよりも約２倍以上の水平方向の剛性を実現しつつ、従来Ｂよりもほぼ半分の重量になる。なお、第三の実施形態の場合でも、底板部２０は、従来Ｂよりも重力方向の剛性が約２．５倍になる。 As shown in FIG. 10, the bottom plate portion 20 of the present embodiment has about 2.5 times the rigidity in the gravity direction and about 3 times the rigidity in the horizontal direction as compared with the conventional B. That is, by forming the rib 90 on the back side of the arrangement surface 22, sufficient strength can be ensured even with a thin thickness of about 2 to 3 mm. For example, the bottom plate portion 20 of the present embodiment is approximately half the weight of the conventional B while achieving a horizontal rigidity of about twice or more that of the conventional B. Even in the case of the third embodiment, the bottom plate 20 has about 2.5 times the rigidity in the gravitational direction as compared with the conventional B.

以上、第一ないし第四の実施形態により本発明を適用した本実施形態の室外機１０を説明したが、本実施形態の室外機１０の有用性又は必要性等について補足説明をする。近年、空気調和機においては、消費電力を低減して省エネ化を図ることは重要である。省エネ化を図る有効な手段として、熱交換器の伝熱面積を増大させることが考えられる。熱交換器の伝熱面積を増加させるには、熱交換器の列数を増やす方法や、高さを増大する方法等がある。しかし、熱交換器の列数を増やす方法では、熱交換器の通風抵抗が増加する結果、送風機の騒音及び消費電力の増加を招く場合ある。熱交換器の高さを増大する方法では、通風抵抗が減少して送風機の騒音も消費電力も低減するが、室外機の寸法が増大する場合がある。 As described above, the outdoor unit 10 of the present embodiment to which the present invention is applied has been described according to the first to fourth embodiments. However, the usefulness or necessity of the outdoor unit 10 of the present embodiment will be supplementarily described. In recent years, it is important to reduce power consumption and save energy in air conditioners. As an effective means for energy saving, it is conceivable to increase the heat transfer area of the heat exchanger. In order to increase the heat transfer area of the heat exchanger, there are a method of increasing the number of rows of heat exchangers, a method of increasing the height, and the like. However, in the method of increasing the number of rows of heat exchangers, the ventilation resistance of the heat exchanger is increased, resulting in an increase in noise and power consumption of the blower. In the method of increasing the height of the heat exchanger, the ventilation resistance is reduced to reduce the noise and power consumption of the blower, but the size of the outdoor unit may be increased.

ところで、ビル用マルチパッケージエアコンにおいては、ビルの屋上等に多台数の連続設置形態となる場合がある。この形態の場合、家庭用ルームエアコンや店舗用パッケージエアコンに適用される横吹き型の室外機では、隣接する機体の吹出し風を自ら吸込むことがあるため、横吹き型の室外機に代えて、上吹き型の室外機を適用するのが一般的である。 By the way, in a multi-package air conditioner for buildings, there are cases where a large number of units are continuously installed on the rooftop of the building. In the case of this form, in a horizontal blow type outdoor unit applied to a home room air conditioner or a store packaged air conditioner, since the blowout air of the adjacent airframe may be sucked by itself, instead of the horizontal blow type outdoor unit, It is common to apply a top blow type outdoor unit.

このようなマルチパッケージエアコンにおいては、製品底面の大きさ、すなわち据付面積のコンパクト化が重要視される。そこで、据付面積をできる限り縮減しつつ、熱交換器の伝熱面積を確保するには、必然的に熱交換器の高さ方向の寸法を増大することになる。室外機の高さが増大すると、例えば搬入や運搬又は保管などの作業が困難になる。そこで、室外機の高さと据付面積の双方を抑えつつ熱交換器の伝熱面積を確保するためには、限られた設置スペース内で、いかに熱交換器の周長（展開長さ）を確保できるかが重要になる。 In such a multi-package air conditioner, it is important to make the size of the product bottom, that is, the installation area compact. Therefore, in order to secure the heat transfer area of the heat exchanger while reducing the installation area as much as possible, the size in the height direction of the heat exchanger is inevitably increased. When the height of the outdoor unit increases, for example, operations such as carry-in, transportation, and storage become difficult. Therefore, in order to secure the heat transfer area of the heat exchanger while suppressing both the height of the outdoor unit and the installation area, the perimeter (deployment length) of the heat exchanger is secured within the limited installation space. Whether it can be done is important.

また、例えばビル用のマルチパッケージエアコンにおいては、比較的大きな空調能力が求められるのが一般的である。例えば、家庭用ルームエアコンや店舗用パッケージエアコンは比較的小さな空調能力（例えば１０馬力）なのに対し、ビル用マルチパッケージエアコンに求められる空超能力は例えば４０馬力を超える。したがって、マルチパッケージエアコンの製品開発においては、比較的小容量な基本モジュールを開発し、その基本モジュールを複数台組み合わせる方式が採用される。例えば、１０馬力を基本モジュールとすれば、１０馬力を３台接続することで３０馬力を実現できる。基本モジュールを複数台組み合わせる方式は、二つの形態が考えられる。第一の形態は、各基本モジュールを現地に搬入し、現地で配管を介して基本モジュールを相互に接続する外付けモジュール方式である。第二の形態は、複数の基本モジュールを1体の大きな筐体として構成する一体型方式である。一体型方式の場合、各基本モジュール間の配管は予め接続されているため、現地の配管接続作業は不要となるので、省工事という観点では望ましい。 For example, in a multi-package air conditioner for buildings, a relatively large air conditioning capacity is generally required. For example, while a room air conditioner for home use and a packaged air conditioner for shops have a relatively small air conditioning capacity (for example, 10 horsepower), the air super capacity required for a multi-package air conditioner for buildings exceeds 40 horsepower, for example. Therefore, in the development of a multi-package air conditioner product, a method of developing a relatively small basic module and combining a plurality of the basic modules is adopted. For example, if 10 horsepower is a basic module, 30 horsepower can be realized by connecting three 10 horsepower units. There are two possible methods for combining a plurality of basic modules. The first form is an external module system in which each basic module is brought into the field and the basic modules are connected to each other through piping. The second form is an integrated system in which a plurality of basic modules are configured as one large casing. In the case of the integrated system, since piping between the basic modules is connected in advance, local piping connection work is unnecessary, which is desirable from the viewpoint of saving work.

ところが、一体型方式の場合は、基本モジュール間の配管接続は1体の筐体内部で接続する必要があるため、熱交換器の周設位置が制約される。具体的には、熱交換器の周長を可能な限り確保する場合、必然的に筐体外周を熱交換器が取り囲むような形態になるが、配管の引き回しスペースと各基本モジュール間を繋ぐ配管の接続を考えると、熱交換器がこれを遮ることになる。したがって、熱交換器の周長を所望に応じて増大させることができず、結果として高さ寸法を増大して熱交換面積を確保することになる。 However, in the case of the integrated system, the piping connection between the basic modules needs to be connected within one housing, and therefore the position of the heat exchanger is limited. Specifically, when the perimeter of the heat exchanger is secured as much as possible, the heat exchanger inevitably surrounds the outer periphery of the housing, but the piping connecting the piping routing space and each basic module Considering this connection, the heat exchanger blocks this. Therefore, the circumference of the heat exchanger cannot be increased as desired, and as a result, the height dimension is increased to ensure a heat exchange area.

このような問題に対する従前の技術として、上吹きタイプの室外機の本体上部は四面、下部は三面を熱交換器の吸込み面とすることで、同一据付面積内で熱交換器の伝熱面積を確保し、省エネ性とコンパクト性を兼ね備えるものがある（例えば特開２００３−２７９０７６号公報）。しかし、この技術は、複数の基本モジュールを組み合わせたマルチパッケージエアコンについては配慮しておらず、基本モジュール間を接続する配管が依然として下部の熱交換器に遮られる。 As a conventional technology for such problems, the upper part of the main unit of the top blow type outdoor unit has four sides and the lower part has three sides as the heat exchanger suction surface, so that the heat transfer area of the heat exchanger can be reduced within the same installation area. There are some that have both energy saving and compactness (for example, Japanese Patent Application Laid-Open No. 2003-279076). However, this technology does not consider a multi-package air conditioner in which a plurality of basic modules are combined, and piping connecting the basic modules is still blocked by the lower heat exchanger.

他の従前の技術として、第一の熱交換器の周設位置を筐体の背面と両側面の半分に制限して接続配管用のスペースを確保するとともに、第一の熱交換器の制限に起因する損失を補填するための第二の熱交換器を別部品として正面に配設するものがある（例えば特開２００３−２７９０７６号公報）。しかし、熱交換器を分離すると、冷媒配管の接続形態が煩雑になるなど所要コストが増大する。 As another conventional technique, the peripheral position of the first heat exchanger is limited to half of the back and both sides of the housing to secure a space for connecting piping and to limit the first heat exchanger. There is one in which a second heat exchanger for compensating for a loss caused by the loss is disposed on the front surface as a separate part (for example, Japanese Patent Application Laid-Open No. 2003-279076). However, if the heat exchanger is separated, the required cost increases, for example, the connection form of the refrigerant pipe becomes complicated.

この点、本実施形態によれば、第一ないし第四の実施形態で説明したとおり、一体型のマルチパッケージエアコン用の室外機を構成する際、各室外機１０ａ、１０ｂの配管用穴２６に接続配管５２を這わすことができる。したがって、接続配管５２を配設するに際し、熱交換器１４の周長を制限せずに済む。その結果、限られた設置面積で熱交換器１４の周長を最大限に確保できるので、省エネ性とコンパクト性を兼ね備えた空気調和機の室外機を実現できる。 In this regard, according to the present embodiment, as described in the first to fourth embodiments, when configuring an outdoor unit for an integrated multi-package air conditioner, the pipe holes 26 of the outdoor units 10a and 10b are provided. The connecting pipe 52 can be broken. Therefore, it is not necessary to limit the circumference of the heat exchanger 14 when the connection pipe 52 is provided. As a result, since the circumference of the heat exchanger 14 can be secured to the maximum with a limited installation area, an outdoor unit of an air conditioner having both energy saving and compactness can be realized.
