  FIG. 1 shows an embodiment of an air conditioning system having an outdoor unit 100 and an indoor unit (s) 150. The outdoor unit 100 generally includes an outdoor unit housing 110, a compressor 120, a coil (s) 130, and a fan 140 (s) 140. In general, an outdoor unit is configured to compress a refrigerant in a gas phase and cool the compressed refrigerant into a liquid. The liquid refrigerant flows into the indoor unit 150 (single or plural).

  The indoor unit 150 (s) may have various structures. Several structures are shown in FIG. The indoor unit (s) may be a wall mounted unit 150a, a ceiling mounted unit 150b, and / or a ventilation duct 150c. The indoor unit (s) 150 is configured to facilitate heat exchange between the indoor air and the refrigerant.

  2A-2D show various views of one embodiment of the outdoor unit 200. FIG. 2A is a side view. As shown, the side view is substantially rectangular and has a height H1 and a length L1. In one embodiment, the height H1 is, for example, about 1550 mm, and the length L1 is, for example, about 1380 mm. The outdoor unit 200 has a housing 210. The housing 210 is configured to have a coil support 212, and the coil support 212 is configured to have coil support frames 212L and 212R. The coil support frames 212L and 212R are configured to support a coil (eg, a condenser coil) 230, which has two coil sections: a first section 230a and a second section 230b. It is configured as follows. These two coil sections, the first section 230a and the second section 230b, are configured to have substantially the same dimensions in some examples. The first section 230a and the second section 230b are in fluid communication with each other so that the refrigerant can flow between the first section 230a and the second section 230b. The coil 230 generally has a height H3. In one embodiment, the height H3 is about 1300 mm, for example. Note that FIG. 2A shows a view of only one side of the outdoor unit 200. The side opposite to the side shown may also have a structure similar to that shown in FIG. 2A.

  The housing 210 has a fan guard (s) 213 disposed on the top panel of the housing 210 (indicated by the number 217 in FIG. 2B). The housing 210 including the fan guard (s) 213 has a height H2. In one embodiment, the height H2 is about 1700 mm.

  FIG. 2B is an end view of the outdoor unit 200. In order to more clearly illustrate the internal space of the outdoor unit 200, the end (end) panel of the outdoor unit 200 is removed. The housing 210 of the outdoor unit 200 can be configured to have a coil support 212.

  The housing 210 has a bottom panel 215 and a top panel 217. The bottom panel 215 is configured to support several components of the outdoor unit 200 (for example, the compressor 220 disposed in the internal space of the outdoor unit 200). The top panel 217 is configured to support the fan guard (s) 213 and the fan 240. As can be seen in the end view, the bottom panel 215 has a width W1 and the top panel 217 has a width W2. In general, the width W1 is smaller than the width W2. In one embodiment, the width W1 is about 800 mm and the width W2 is about 1040 mm.

  As shown in FIG. 2B, coil support 212 and coil 230 extend substantially vertically between bottom panel 215 and top panel 217 and from bottom panel 215 to top panel 217. , Respectively, spread outward in a vertical direction V1 perpendicular to the bottom panel 215. A coil support 212 extending so as to extend outward can provide support surfaces S1 and S2 for supporting the coil 230, respectively. The support surfaces S1 and S2 extend in the vertical direction V1 from the bottom panel 215 to the top panel 217, and are inclined outward. The support surfaces S1 and S2 inclined outward have an angle α1 and an angle α2 with respect to the vertical direction V1. The angle α1 and the angle α2 can be configured to be substantially the same. Angle α1 and angle α2 can range from about 0 degrees to about 90 degrees. In one embodiment, angle α1 and angle α2 are about 8 degrees. The coil support 212 and the coil 230 that extend outwardly form more space between the fan 240 (and / or the fan guard 213) and the coil 230 in the region near the top panel 217. Can help.

  The top panel 217 may have a hole (not shown) that approximately matches the dimensions of the fan guard 213. The fan guard has a width W3. In one embodiment, the width W3 is about 610 mm.

  Referring to FIG. 2C, a top view of the outdoor unit 200 is shown. When viewed from above, the outdoor unit 200 has a substantially hexagonal top panel 217. The outdoor unit 200 has two coils 230. These two coils 230 are configured to substantially face each other. Each of the coils 230 is configured to have two sections, eg, coil sections 230a and 230b. In the longitudinal direction defined by the length L1, the two coil sections 230a and 230b are arranged obliquely with respect to each other. As used herein, the terms “diagonal (ly) in relation to each other” and “diagonally positioned” generally refer to two adjacent Matching coil sections (eg, 230a and 230b) have apexes away from the interior space of the housing 210 along the longitudinal direction defined by the length L1, particularly as seen in the top view (eg, FIG. 2C). It is meant to be arranged to form a facing angle (ie, angle β described below).

  As shown in FIG. 2C, the two coils 230 are generally facing each other. Since the two coil sections of each of the two coils 230 (for example, one coil section 230a and 230b of the coil 230) are arranged obliquely, the length L1 of the two coils 230 facing each other The vertical distance D2 is larger toward the middle portion of the length L1.

  Each section of the coil 230 substantially corresponds to one side of a hexagonal top profile. In the illustrated embodiment, for example, each coil 230 corresponds to two adjacent sides of the hexagonal top profile. Coil sections 230a and 230b are supported by support surfaces provided by coil support frames 212L and 212R of coil support 212. For example, the first section 230a and the second section 230b are supported by support surfaces S3 and S4 (defined by coil support frames 212L and 212R, respectively). As illustrated, the first section 230a and the second section 230b are disposed obliquely with respect to each other. The two support surfaces S3 and S4 form an angle β. The angle β can be in the range of 90 degrees to 180 degrees. In one embodiment, angle β is, for example, about 172 degrees.

  FIG. 2D is a perspective view of the outdoor unit 200. As shown and described above, the bottom panel 215 is also configured to be hexagonal, which is generally smaller than the hexagonal top panel 217. The coil support frame 212, the coil 230, and / or the hexagonal top panel 217 and the bottom panel 215 that extend so as to expand form the outer shape of the outdoor unit 200 similar to the shape of a flower. One of the coil support frames 212 can form two coil support surfaces S3 and S4 (defined by support frames 212R and 212L, respectively). The coil support surface S3 and the coil support surface S4 are disposed obliquely with respect to each other. The two coil support surfaces S3 and the coil support surface S4 each support one section of the coil 230, for example, the first section 230a or the second section 230b. The first section 230a and the second section 230b are disposed obliquely with respect to each other. The two coils 230 surround the internal space of the outdoor unit 200 (configured to accommodate the compressor 220 and / or other components of the outdoor unit 200).

  In the embodiment shown in FIGS. 2A-2D, the top panel 217 is configured to accommodate two fans 240. This is exemplary. The top panel may be configured to accommodate more or less than two fans. As shown in FIG. 3, in one embodiment, the top panel 317 can be configured to accommodate three fans 340. In some embodiments, the top panel may be configured to accommodate only one fan.

  The top panel can be configured to have a shape other than a hexagonal shape. For example, as shown in FIG. 4, in some embodiments, the top panel 417 can be configured to be generally octagonal in shape. The coil support frame 412 may be configured to have a transition 418 between two sections 412L and 412R arranged at an angle.

  As shown in FIG. 5, in operation, a plurality of flower-shaped outdoor units having a similar structure, such as 500a, 500b and 500c, can be placed in close proximity to each other. Each of the coils 530a, 530b-1, 530b-2 and 530c is configured to have two coil sections arranged at an angle, as shown, for example, in FIGS. 2A-2D. Coil sections of adjacent outdoor units, such as 530a and 530b-1, which are arranged at an angle, can provide a space between adjacent outdoor units, for example, 500a and 500b.

  Furthermore, the coils 530a, 530b-1, 530b-2, and 530c are inclined outward toward the upper portions of the outdoor units 500a, 500b, and 500c, respectively. This particularly helps to increase the space between the adjacent coils 530a, 530b-1, 530b-2 and 530c toward the bottom of the outdoor units 500a, 500b and 500c.

  The coil sections that are arranged obliquely and inclined outward can help increase the space between adjacent coils. This space can assist in promoting the inflow of airflow into the space between adjacent coils, as shown by arrows a1 and a2. This can assist in increasing the heat exchange efficiency of coils 530a, 530b-1, 530b-2 and 530c.

Experimental Data FIGS. 6A-6C illustrate a computational fluid dynamics modeling process for simulating the velocity of airflow flowing through a coil along the height of an outdoor unit embodiment 600a and 600b. As shown, FIG. 6A shows a flower shaped outdoor unit 600a that is configured to have a coil 630a that is diagonally disposed and extends outwardly. FIG. 6B shows an outdoor unit 600b configured to have coils 630b arranged obliquely. However, the entire coil 630b does not extend so as to expand outward like the coil 630a illustrated in FIG. 6A. The coil 630a of the outdoor unit 600a has a length L6, and the length L6 is substantially the same as the length L7 of the coil 630b of the outdoor unit 600b. The outdoor unit 600a has a bottom width W7a, and the bottom width W7a is substantially the same as the bottom width W7b of the outdoor unit 600b. The outdoor unit 600a has an upper width W8a, and the upper width W8a is larger than the upper width W8b of the outdoor unit 600b. The upper width W8a, which is larger than the upper width W8b, is due to the coil 630 extending so as to expand outward. The components of the outdoor unit 600a and the outdoor unit 600b, such as a fan and a compressor, are configured to have similar specifications.

  FIG. 6C shows a simulation of the air velocity along the height H7a of the outdoor unit 600a and along the height H7b of the outdoor unit 600b. The height H7a is substantially shorter than the height H7b. This is because the coil 630a extends so as to expand outward. In FIG. 6C, the horizontal axis represents the average air velocity (meter / second) (m / s). The vertical axis indicates the height of the measurement position as a percentage of the height at height H7a or height H7b.

  As shown in FIG. 6C, in the outdoor unit 600a, the minimum air speed is about 1 m / s near the bottom of the outdoor unit 600a, and the maximum air speed is about 2 m near the top of the outdoor unit 600a. / S. In the outdoor unit 600a, the difference between the minimum air speed and the maximum air speed is about 1 m / s. In comparison, the minimum air speed of the outdoor unit 600b is about 1 m / s near the bottom, while the maximum air speed is about 2.5 m / s near the top of the outdoor unit 600b. The difference between the minimum air velocity and the maximum air velocity of the outdoor unit 600b is about 1.5 m / s, which is about 50% larger than the difference (1 m / s) in the outdoor unit 600a. Therefore, the distribution of the air velocity along the height H7a of the outdoor unit 600a is more uniform than the distribution of the air velocity along the height H7b of the outdoor unit 600b. The air velocity in the vicinity of the top of the outdoor unit 600a is lower than the air velocity in the outdoor unit 600b because the coil 630a extending so as to expand outward is in the vicinity of the top of the outdoor unit 600a. This is probably because a space larger than the space near the top of the outdoor unit 600b is formed.

  With regard to the above description, it will be understood that changes in detail may be made without departing from the scope of the present invention (invention), particularly with respect to the materials of construction, shape, dimensions, and placement of components. The specification and described embodiments are merely illustrative, and the true scope and spirit of the present invention (invention) is intended to be indicated by the broad meaning of the appended claims.
