Description

The present invention relates to an air conditioning system provided in one room of an apartment building.

In living spaces such as houses and condominiums, the heating works well in the sunny south side living room in winter and it is easy to warm up, but the north side living room where the sunshine effect is not obtained is difficult to heat, and condensation occurs on the north side outer wall and openings. Cheap. Improvements can be seen when the outer walls and openings are thermally remodeled, but the relative difference in thermal conditions between the south zone and the north zone remains.

Under these circumstances, the room on the north side will be cooler than the room on the south side, and the heating equipment in the room on the north side will need to operate at a lower heating efficiency than the room on the south side. Even if the heater is turned on in the room on the north side, the amount of heat released is large and it takes time for the room temperature to rise because the outside air is cold.

Furthermore, in the non-residential space, although the sunshine effect cannot be obtained, there are many cases in which no heating facility is installed. In particular, wet areas such as bathrooms tend to have high humidity, and ventilation equipment is usually provided to prevent mold, so they are rarely heated. Air-conditioning systems that use fans to exchange indoor air with the outside are generally used as ventilation equipment.

The air conditioning system includes a humidity control system that supplies low-humidity air indoors and exhausts high-humidity air outdoors (see, for example, Patent Document 1), and introduces air between spaces with different temperatures. There is a temperature control system or the like (see, for example, Patent Document 2) that reduces or discharges the gas.

By adjusting the temperature and humidity of the air in the living space using the air-conditioning system, it is possible to improve the comfort of living. said to be able to perform.

FIG.

Hereinafter, embodiments of the present invention will be described based on examples, but the embodiments of the present invention are not limited to these.

FIG. 1 is a diagram showing the layout of a living space 10 equipped with an air conditioning system 1 according to one embodiment of the present invention. FIG. 2 is a schematic diagram representing the transport of warm air by an air conditioning system 1 according to an embodiment of the invention. FIG. 3 is a diagram showing an overview of the air conditioning system 1 according to one embodiment of the present invention.

The air conditioning system 1 is applied, for example, to a living space that is a room in an apartment as shown in FIG. This living space is used in a living space consisting of a living room space 2 on the south side, a living room space 3 on the north side, and a non-living room space 4 other than the living room spaces, which is mainly located in the middle latitude of both living room spaces.

In the living space, the air conditioning system 1 includes at least one south living room space air supply/exhaust port 21 provided on the wall or ceiling surface of the south living room space 2 and at least one north living room provided on the wall or floor of the north living room space 3. A space air supply/exhaust port 31, at least one non-living room space air supply/exhaust port 41 provided in the non-living room space 4, a south side living room space air supply/exhaust port 21, and a north side living room space air supply/exhaust port 21 provided above the ceiling, in the wall surface, and in the underfloor. It comprises a duct 5 connecting the exhaust port 31 and the non-residential space air supply/exhaust port 41, and a circulation fan 6 provided in the duct 5 above the ceiling.

The living room space 2 on the south side is composed of, for example, a living room and a Japanese-style room facing a balcony on the south side. The north living room space 3 is composed of, for example, two Western-style rooms facing the common corridor outside on the north side. The non-living room space 4 is composed of, for example, a bathroom 42 , a washroom 43 , a corridor 44 , a toilet 45 , an entrance 46 and a kitchen 47 .

Each of the south living room space air supply/exhaust port 21, the north living room space air supply/exhaust port 31, and the non-living room space air supply/exhaust port 41 may be provided at a plurality of locations in order to enhance the air conditioning effect.

The duct 5 has a heat insulating material 7 on at least a part of its circumference. The circulation fan 6 sends the air in the south living room space 2 to the north living room space 3 through the duct 5 .

Here, the materials of the duct 5 and the heat insulating material 7 are not particularly limited, and those used for ordinary heat insulating or non-heat insulating residential piping can be used.

Further, it is preferable that the duct 5, the circulation fan 6, and the air supply/exhaust ports described above have a function of purifying the air passing through them. In this specification, the purifying function means a function capable of exhibiting at least one of deodorant, sterilization, and antibacterial effects on the air passing through. These deodorant, sterilization, and antibacterial effects are obtained by, for example, placing at least one of a deodorant, a sterilizer, and an antibacterial agent in at least one of the duct 5, the circulation fan 6, and each air supply/exhaust port. It is played by being played.

The air-conditioning system of the present invention is not limited to being installed in newly built properties, and may be installed in existing properties through renovation. For example, when remodeling a condominium, a new ceiling is installed at a position slightly lower than the conventional ceiling position, and a duct 5 and a circulation fan 6 are installed between the conventional ceiling and the new ceiling to change the structure of the building. This system can be introduced relatively easily without such a large construction work.

It should be noted that there is no particular limitation on which room the circulation fan 6 is installed in, but in consideration of the comfort of the living space, the ceiling height is low, the ceiling is wide, and the non-residential time is relatively short. It is preferable to provide in the upper part of living room space. When the circulation fan 6 is provided in the upper part of the living room space, if the height of the ceiling is lowered due to the height of the housing of the circulation fan 6, the occupants may feel a sense of blockage in the space, and the operating noise of the fan. This is because it can cause noise.

For example, the circulation fan 6 is preferably provided above the bathroom 42 . This is because, in addition to the above reasons, the space for installing the housing of the circulation fan 6 is wide and the installation is easy.

Next, the air conditioning system 1 of this embodiment will be described in detail with reference to the drawings.

FIG. 3 is a diagram showing an outline of the air conditioning system 1 of this embodiment. The air-conditioning system 1 operates the circulation fan 6 to transfer the air in the south living room space 2 to the north living room space 3 and the non-living room space 4 other than both living room spaces through the duct 5 . In general, the air in the living room space on the south side is easily warmed by the sunshine effect, and is often higher in temperature than the air in the living room space on the north side and the non-living room space.

The circulation fan 6 sucks the warm air of the south living room space 2 from the air supply/exhaust port 21, for example, when heating and air-conditioning the south living room space 2 in winter. The sucked air is transported through the duct 5 to the north living room space 3 where the sunshine effect is low, thereby exerting a heating effect on the north living room space 3 (see FIG. 2). A heat insulating material 7 is provided around the pipe circumference of the duct 5 so as not to lose warm air heat during transportation.
In addition, for example, when cooling air conditioning is performed in the south living room space 2 in summer, the cooling effect exerted in the south living room space 2 can be expanded to the north living room space 3 and the non-living room space 4 by similar air transportation. and improve cooling efficiency.

Here, FIG. 4 is a diagram showing an air curtain effect due to air blowing in the vicinity of the window opening. As shown in FIG. 4, in the air conditioning system 1, the air supply/exhaust port 31 for the living room space on the north side is provided near the north window opening where dew condensation is likely to occur. More specifically, a north living room space air supply/exhaust port 31 is formed on the upper surface of the window sill of the waist window, and warm air is exhausted between the curtain/blind 32 and the inner window 33 . Warm air is exhausted from the vicinity of the window opening to raise the temperature of the air near the window, thereby increasing the amount of saturated water vapor and reducing the occurrence of dew condensation. In addition, the air blown out near the window acts as an air curtain, blocking the transfer of heat 35 from the indoor air to the north-facing window as shown in FIG. improves.

Further, the above-mentioned north-side living room space air supply/exhaust port 31 may be provided so that air can be blown between the inner window 33 and the outer window 34 of the double-glazed window. FIG. 5 is a diagram showing ventilation between the inner window 33 and the outer window 34 of the double glazing. By heating the air between the double-glazed windows, the temperature of the inner window glass is less likely to drop, so the cooling of the indoor air on the inner surface of the inner window glass is suppressed, and condensation occurs more effectively in the room. can be prevented.

FIG. 6 is a plan view showing a meandering arrangement of non-insulated ducts in the air conditioning system 1. FIG. As shown in FIG. 5, in the air conditioning system 1, the duct 5 passes under the floor of the living room space 3 on the north side, and only the portion adjacent to the living room space 3 on the north side is non-insulated. Therefore, it is possible to dissipate heat toward the north room space 3 . Furthermore, since the duct 5 is arranged in a meandering manner so as to increase the contact area with the floor surface of the north living room space 3, the heat radiation efficiency is enhanced.

As a result, since the floor and wall surfaces of the living room space 3 on the north side have a heating effect, it is possible to heat even a space that does not have an air supply/exhaust port, and also heat the lower corner of the room where the heat cannot be spread only by blowing air. By doing so, the space can be efficiently heated. In addition, by widening the contact area with the space to be heated, the amount of heat transfer is increased, and the heating effect is further improved.

Further, it is preferable that the inside of the duct 5, the circulation fan 6, and each air supply/exhaust port has a purification function. As a result, it is possible to prevent living odors in the living room space 2 on the south side and germs generated in the kitchen from being carried to other spaces, thereby further improving the comfort of the air supply destination space.

According to the present invention, for example, the comfortable room temperature air of the LDK, which is air-conditioned by an air conditioner such as an air conditioner until before going to bed, is sent to the bedroom in the north living room space 3 before going to bed and during sleeping, and the air conditioning at bedtime , pre-air conditioning can be performed. Even if the bedroom is equipped with an air conditioner, by using the already air-conditioned LDK air, the thermal efficiency can be improved, and the use frequency and load of the air conditioner in the bedroom can be reduced.

Further, the air conditioning system 1 has a function of switching air supply destinations, and in addition to the north side living room space 3, the non-living room space 4 includes a bathroom 42, a washroom 43, a corridor 44, a toilet 45, an entrance 46, a kitchen, and a kitchen. 47, air can also be supplied to at least one space. As a method of switching the air supply destination, for example, switching of the flow path of the duct 5 is possible. Alternatively, all the air supply/exhaust ports and the air supply/exhaust ports can be individually opened and closed according to the intake/air supply destination, so that the same circulation fan 6 can supply air to a desired room.

As a result, for example, by supplying air to the north living room space 3 and the bathroom 42, it is possible to increase the comfort of the occupant in the north living room space 3 while warming the bathroom to which the resident plans to go later. can. Since it is possible to supply warm air to a plurality of locations at the same time or sequentially in this manner, further improvement in comfort can be expected.

FIG. 7 is a diagram showing reverse operation of the air conditioning system 1 in summer. As shown in FIG. 6, the air-conditioning system 1 can supply the air in the north living room space 3 to the south living room space 2 and the non-living room space 4 by rotating the circulation fan 6 in reverse or by switching the flow path. be.

For example, in the summer, relatively low-temperature air in the north living room space 3 is sucked from the air supply/exhaust port 31, transported to the south living room space 2 through the duct 5, and discharged from the air supply/exhaust port 21, so that the south living room space 2 cooling effect can be exhibited. As a result, comfort and cooling efficiency of the south room space 2 are improved, and an energy saving effect is exhibited. At this time, the air supply/exhaust port 31 and the air supply/exhaust port 21 are directly connected to the duct 5, and the duct 5 can be used as the ventilation passage.

FIG. 8 is a diagram showing an air conditioning system 1 including a ventilation unit 8 that performs ventilation between outdoor air and indoor air, among the air conditioning systems 1 according to an embodiment of the present invention. As shown in FIG. 8, the air conditioning system 1 includes a ventilation section 8 having a south ventilation section 81 located on the south side and a north ventilation section 82 located on the north side. Each ventilation unit has an exhaust port for exhausting indoor air of the condominium to the outside and an air supply port for supplying outdoor air to the interior of the condominium. The north ventilation section 82 is connected to the circulation fan 6 via a ventilation duct 51 that is part of the duct 5 . Note that the south ventilation section 81 may be connected to the circulation fan 6 via a ventilation duct.

According to this air conditioning system 1, a part of the duct 5 leads to the outside of the living space via the ventilation part 8, and a part of the air blowing route is set to the outside of the living space. Ventilation with the outside air is possible by also providing an air supply route. Therefore, the air-conditioning system 1 can perform planned ventilation for 24 hours.

FIG. 9 is a diagram showing an air conditioning system 1 including a heat exchange ventilator 9 that exchanges heat between outdoor air and indoor air, among the air conditioning systems 1 according to an embodiment of the present invention. As shown in FIG. 9, the air conditioning system 1 includes a ventilation section 9 having a south heat exchange ventilation section 91 located on the south side and a north heat exchange ventilation section 92 located on the north side. Each ventilation unit has an exhaust port (hood) arranged on the outdoor side and a heat exchange ventilation device arranged on the indoor side.

According to this air-conditioning system 1, the effect of the circulation fan is maintained by supplying air into the living space after the temperature of the air taken in from the outside is brought close to room temperature through heat exchange with the air in the living space that is exhausted. Ventilation can be done while This further improves comfort in the living space.
