Description
DESCRIPTION Title of Invention
HEAT SOURCE UNIT
Technical Field
[0001] The present invention relates to a heat source unit constituting an air-conditioning device and a heat pump water heater.
Background Art
[0002] An air-conditioning device and a heat pump water heater are provided with a heat source unit including an air heat exchanger. The air heat exchanger includes a plurality of heat transfer tubes and a plurality of fins. Refrigerant for exchanging heat with air that is supplied to the heat source unit is caused to flow through the heat transfer tubes. The fins are combined with the heat transfer tubes to increase efficiency of heat exchange between refrigerant and air. A heat source unit described in Patent Literature 1 includes a copper round tube as the heat transfer tube, and an aluminum fin as the fin.

Summary of Invention
Technical Problem [0004] The heat transfer tube of an air heat exchanger described in Patent Literature 1 is a round tube, and thus, a contact area with air that is supplied to the heat source unit is small. Accordingly, many round tubes are necessary to achieve high-capacity heat exchange capacity. Therefore, the number of rows of air heat exchangers to be installed in the heat source unit is increased, and there is a concern that a manufacturing cost is increased. In other words, desired heat exchange capacity may not be achieved depending on the number of round tubes that are installed. [0005] The present invention has been made in view of such circumstances, and has its object to provide a heat source unit capable of achieving high heat exchange capacity, without increasing the number of heat transfer tubes.
Solution to Problem [0006] A heat source unit according to an embodiment of the present invention is a heat source unit including a plurality of heat exchangers each including a plurality of fins and a plurality of flat tubes, and a machine chamber of a cuboid shape, where the plurality of heat exchangers are provided on an upper part of the machine chamber, and of the plurality of heat exchangers, a pair of heat exchangers that are disposed facing each other in a lateral direction of the machine chamber are tilted in such a way that a gap between end portions on a side far from the machine chamber is greater than a gap between end portions on a side close to the machine chamber. Advantageous Effects of Invention [0007] With the heat source unit according to the embodiment of the present invention, flat tubes are used as heat transfer tubes of air heat exchangers, and thus, a surface area where air that is supplied to the heat source unit contacts is great compared to a case where round tubes are used. Therefore, a heat exchange area the same as a heat exchange area when round tubes are used as the heat transfer tubes of the air heat exchangers may be secured by a smaller number of heat transfer tubes than when round tubes are used as the heat transfer tubes of the air heat exchangers, and thus, a manufacturing cost of the heat source unit may be reduced. Furthermore, the heat exchangers of the heat source unit according to the embodiment of the present invention are tilted, and thus, condensed dew that is generated at the time of heating operation is not retained on flat portions of the flat tubes. Accordingly, freezing of dew at the heat exchangers at the time of heating operation may be prevented, and heating operation may be performed while maintaining high heat exchange capacity. In this manner, the embodiment of the present invention achieves a heat source unit having high heat exchange capacity, for which the number of heat transfer tubes is prevented from being increased.

[0013] In Fig. 1, a space occupied by the machine chamber 4 is indicated by a dotted line. The machine chamber 4 includes a base frame 41, four columns, four mid-columns, and an upper beam 44. The four columns are a column 42A, a column 42B, a column 42C, and a column 42D. The four mid-columns are a mid-column 43A, a mid-column 43B, a mid-column 43C, and a mid-column 43D. The base frame 41 is a plate member having a rectangular shape. The column 42A, the column 42B, the column 42C, and the column 42D are provided at four corner portions of the base frame 41 while extending in a direction perpendicular to the base frame 41.
The mid-column 43A and the mid-column 43B are provided between the column 42A and the column 42C while being spaced apart from each other in a longitudinal direction of the base frame 41. The mid-column 43C and the mid-column 43D are provided between the column 42B and the column 42D while being spaced apart from each other in the longitudinal direction of the base frame 41.

The plurality of element devices installed in the machine chamber 4 includes a waterside heat exchanger 3, a compressor 31 constituting a refrigerant circuit, and a control board 32. Additionally, in the following description, the air heat exchangers 1A, 1B, 1C, and 1D may be collectively referred to as the air heat exchanger(s) 1.
Furthermore, the column 42A, the column 42B, the column 42C, and the column 42D may be collectively referred to as the column(s) 42. Moreover, the mid-column 43A, the mid-column 43B, the mid-column 43C, and the mid-column 43D may be collectively referred to as the mid-column(s) 43.
[0014] Moreover, as shown in Fig. 2, the air heat exchanger lA and the air heat exchanger 1B facing each other in a lateral direction of the machine chamber 4 are tilted in such a way that a gap between end portions on a side far from the machine chamber 4 is greater than a gap between end portions on a side close to the machine chamber 4. That is, the air heat exchanger 1A and the air heat exchanger 1B are tilted to form a V shape when seen from a side of the heat source unit 100. The air heat exchange 1C and the air heat exchange 1D facing each other in the lateral direction of the machine chamber 4 are also tilted to form a V shape. In Embodiment 1, a tilt angle a of the air heat exchanger 1A is 65 to 80 degrees. The same can be said for tilt angles of the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1 D. [0015] As shown in Fig. 3, a base 10 is provided at the upper beam 44 of the machine chamber 4. The base 10 is supported by the columns 42 and the mid-columns 43. A plurality of rubber sheets 13 are provided at the base 10. The air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1D are disposed on the base 10 across the rubber sheets 13. Moreover, the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1C, and the air heat exchanger 1D are tilted in the manner described above. A side panel 50 is provided between the air heat exchanger 1A and the air heat exchanger 1 C. A side panel 51 is provided between the air heat exchanger 1A and the air heat exchanger 1 B. Additionally, a side panel (not shown) the same as the side panel 50 is also provided between the air heat exchanger 1 B and the air heat exchanger 1 D. Furthermore, a side panel (not shown) the same as the side panel 51 is also provided between the air heat exchanger 1C and the air heat exchanger 1 D. [0016] Fig. 5 is a diagram schematically showing a configuration of the air heat exchanger of the heat source unit of Embodiment 1. Fig. 6 is a diagram schematically showing the air heat exchanger, the air heat exchanger being cut at a position of a line B-B in Fig. 5 and seen from a direction of arrows. As shown in Fig. 5, the air heat exchanger 1 is a parallel-flow heat exchanger, and includes a pair of headers 9, a plurality of aluminum flat tubes 7, and a plurality of corrugated fins 8. The plurality of aluminum flat tubes 7 are installed between the pair of headers 9, and both end portions thereof are connected to the headers 9. The plurality of aluminum flat tubes 7 are disposed, between the pair of headers 9, in parallel to one another while being spaced apart from one another, with flat portions facing one another.
The corrugated fins 8 are provided between the facing flat portions of the plurality of aluminum flat tubes 7.
[0017] As shown in Fig. 4, when seen from a direction perpendicular to the aluminum flat tube 7, the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 10 are each bent at an angle of 90 degrees at a position that is offset to one end portion from a center of the aluminum flat tube 7 in a longitudinal direction. That is, when seen from one end portion of the header 9, each of the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1D is L-shaped. The air heat exchanger 1A and the air heat exchanger 1B face each other in the lateral direction of the machine chamber 4, and the air heat exchanger 1C and the air heat exchanger 1D face each other in the lateral direction of the machine chamber 4. The air heat exchanger 1A and the air heat exchanger 1C are arranged next to each other in a longitudinal direction of the machine chamber 4, and the air heat exchanger 1B and the air heat exchanger 1D are arranged next to each other in the longitudinal direction of the machine chamber 4. Furthermore, a short side portion 1AS of the air heat exchanger 1A and a short side portion 1 BS of the air heat exchanger 1B face each other in the lateral direction of the machine chamber 4, and a short side portion 1 CS of the air heat exchanger 1C and a short side portion 1 DS of the air heat exchanger 1D face each other in the lateral direction of the machine chamber 4. Moreover, a long side portion 1AL of the air heat exchanger 1A and a long side portion 1CL of the air heat exchanger 1C are arranged next to each other in the longitudinal direction of the machine chamber 4, and a long side portion 1 BL of the air heat exchanger 1B and a long side portion 1 DL of the air heat exchanger 10 are arranged next to each other in the longitudinal direction of the machine chamber 4. Accordingly, as a whole, the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1D form a rectangular frame. Moreover, a corner portion 1AE, a corner portion 1 BE, a corner portion 1 CE, and a corner portion 1 DE that are bent 90 degrees and that are, respectively, of the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1 D, are positioned at corner portions of the rectangle.
[0018] The heat source unit 100 of Embodiment 1 is disposed in such a way that a direction of flow of air that is supplied intersects a long side portion of the aluminum flat tube 7 of the air heat exchanger 1. Accordingly, air that is supplied is guided between the facing flat portions of the plurality of aluminum flat tubes 7, and is caused to flow, at the aluminum flat tubes 7, along a width direction perpendicular to the longitudinal direction.
[0019] Fig. 7 is a diagram for describing an effect of using a flat tube in the air heat exchanger. In Fig. 7, a flow of air that is supplied to the heat source unit 100 is indicated by arrows. As described above, in Embodiment 1, the heat transfer tube of the air heat exchanger 1 is the aluminum flat tube 7, and air that is supplied to the heat source unit 100 flows, at the aluminum flat tube 7, along the width direction perpendicular to the longitudinal direction. As shown in Fig. 7, a surface area of the aluminum flat tube 7 where air that is supplied to the heat source unit 100 contacts is great compared to a case of using a round tube as the heat transfer tube.
Therefore, according to Embodiment 1, a heat exchange area the same as a heat exchange area when round tubes are used as the heat transfer tubes of the air heat exchanger may be secured by a smaller number of heat transfer tubes than when round tubes are used as the heat transfer tubes of the air heat exchanger. As a result, a manufacturing cost of the heat source unit 100 may be reduced.
[0020] Fig. 8 is a diagram for describing an effect of disposing the air heat exchanger in a tilted manner. In the case where a flat tube is used as the heat transfer tube of the air heat exchanger, condensed dew that is generated at the time of heating operation is possibly retained on the flat portion of the flat tube. In Embodiment 1, the air heat exchangers 1 facing each other in the lateral direction of the machine chamber 4 are tilted into a V shape. Therefore, according to Embodiment 1, condensed dew 16 flows down in a vertical direction, as shown in Fig. 8, without being retained on the flat portion of the aluminum flat tube 7. As a result, freezing of dew at the air heat exchanger 1 at the time of heating operation may be prevented, and heating operation may be performed while maintaining high heat exchange capacity.
[0021] Figs. 9 and 10 are diagrams schematically showing modifications of the arrangement of the air heat exchangers. In Embodiment 1, the air heat exchanger 1 is bent into an L shape, and the long side portion extends along the longitudinal direction of the machine chamber 4, and the short side portion extends in the lateral direction of the machine chamber 4, but such a case is not restrictive. The air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1C, and the air heat exchanger 1D may be formed in the manner shown in Fig. 9. That is, angles of the corner portion 1AF of the air heat exchanger 1A, the corner portion 1 BF of the air heat exchanger 1 B, the corner portion 1CF of the air heat exchanger 1 C, and the corner portion 1 DF of the air heat exchanger 1D are greater than 90 degrees. The long side portion 1AL of the air heat exchanger 1A and the long side portion 1CL of the air heat exchanger 1C are arranged next to each other in the longitudinal direction of the machine chamber 4, and the long side portion 1 BL of the air heat exchanger 1B and the long side portion 1 DL of the air heat exchanger 1D are arranged next to each other in the longitudinal direction of the machine chamber 4. The short side portions 1AS, 1 BS, 1 CS, and 1DS of the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1C, and the air heat exchanger 1 D, respectively, intersect the lateral direction of the machine chamber 4.
[0022] Furthermore, as shown in Fig. 10, a corner portion lAG may be bent at an obtuse angle at a center of the aluminum flat tube 7 in the longitudinal direction, when the air heat exchanger 1A is seen from a direction perpendicular to the aluminum flat tube 7. A corner portion 1 BG of the air heat exchanger 1 B, a corner portion 1 CG of the air heat exchanger 1C, and a corner portion 1 DG of the air heat exchanger 1D are also formed in the same manner. Moreover, the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1D are disposed with the corner portion 1AG, the corner portion 1BG, the corner portion 1 CG, and the corner portion 1 DG facing toward an outer side of the heat source unit 100.
[0023] The air heat exchanger 1 of Embodiment 1 is, but not limited to, a parallel-flow heat exchanger. A fin-and-tube heat exchanger where a plurality of plate-shaped fins are disposed between the pair of headers 9 and the aluminum flat tubes penetrate the plurality of fins may be alternatively used as the air heat exchanger.
Fig. 11 is a diagram for describing an effect of a modification of Embodiment 1. Fig. 11 shows a cross section of a fin-and-tube air heat exchanger that is cut at a similar position as the line B-B in Fig. 5. An air heat exchanger 110 includes plate-shaped fins 180 and aluminum flat tubes 170. The aluminum flat tubes 170 penetrate the fins 180. As shown in Fig. 11, by disposing the air heat exchanger 110 in a tilted manner described above, the condensed dew 16 that is generated at the time of heating operation is prevented from being retained on the surface of the flat tubes of the aluminum flat tubes 170, and an advantageous effect the same as that described above may be obtained.
[0024] Embodiment 2.
Fig. 12 is a diagram schematically showing heat source exchangers, where a heat source unit according to Embodiment 2 of the present invention is seen from above. Structural elements similar to the structural elements of Embodiment 1 are denoted by same reference signs as those in Figs. 1 to 11. With a heat source unit of Embodiment 2, the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1D are disposed in a same manner as that shown in Fig. 9. The heat source unit 200 includes two spray pipes 18 and a plurality of spray nozzles 19. The spray pipes 18 are made of resin. The spray pipes 18 and the spray nozzles 19 are disposed between the air heat exchanger 1A and the air heat exchanger 1B facing each other in the lateral direction of the machine chamber 4, and between the air heat exchanger 1C and the air heat exchanger 1D facing each other in the lateral direction of the machine chamber 4. In other words, the spray pipes 18 and the plurality of spray nozzles 19 are installed in a square space formed by the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 10. The two spray pipes 18 are disposed in parallel to each other in the longitudinal direction of the machine chamber 4. The plurality of spray nozzles 19 are attached to the two spray pipes 18 in a manner facing the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1 D. Water that is supplied to the spray pipes 18 is sprayed onto the air heat exchanger 1A, the air heat exchanger 1 B, the air heat exchanger 1 C, and the air heat exchanger 1D through the spray nozzles 19.
[0025] Fig. 13 is a diagram schematically showing a state in which water is sprayed onto the air heat exchanger from the spray nozzle. In the case where a chiller device where the heat source unit 200 is installed is to perform cooling operation, it is difficult to achieve cooling performance of the heat source unit 200 in an environment where an outside air temperature exceeds 35 degrees C, and thus, spray operation is performed in such an environment. At the time of execution of the spray operation, when water is supplied to the spray pipes 18 and the supplied water is sprayed from the spray nozzles 19 onto the air heat exchangers 1, water drops 20 hit end portions, of the aluminum flat tubes 7, on sides where the spray pipes 18 are disposed. In Embodiment 2, as in Embodiment 1, the air heat exchangers 1 are disposed being tilted into a V shape, and the aluminum flat tubes 7 are tilted in the manner shown in Fig. 13. Accordingly, the water drops 20 flow on the flat portions of the aluminum flat tubes 7 and flow down in the vertical direction from opposite end portions after hitting the end portions, of the aluminum flat tubes 7, on the sides where the spray pipes 18 are disposed.
[0026] In a case where the air heat exchangers 1 are not tilted, the water drops 20 flow down in the vertical direction without flowing to the opposite end portions of the aluminum flat tubes 7, after hitting the end portions, of the aluminum flat tubes 7, on the sides where the spray pipes 18 are disposed. In contrast, according to Embodiment 2, the water drops 20 flow on the flat portions of the aluminum flat tubes 7, and thus, a high spraying effect may be obtained compared to a case where the air heat exchangers 1 are not tilted, and the cooling performance of the heat source unit 200 may be further increased.
[0027] The air heat exchanger 1 of Embodiment 2 is, but not limited to, a parallel-flow heat exchanger. The spray pipes 18 and the spray nozzles 19 mentioned above may be provided at a heat source unit including fin-and-tube air heat exchangers the same as the air heat exchanger in Fig. 11. Fig. 14 is a diagram schematically showing a state in which water is sprayed from the spray nozzle onto an air heat exchanger of a modification of Embodiment 2. Fig. 14 shows a cross section obtained by cutting at a similar position as the line B-B in Fig. 5. When an air heat exchanger 110 is tilted in the manner described above, the water drops 20 that are sprayed from the spray nozzles 19 flow on the flat portions of the aluminum flat tubes 7 and flow down in the vertical direction from the opposite end portions after hitting the end portions, of the aluminum flat tubes 7, on the sides where the spray pipes 18 are disposed. Accordingly, the modification may also achieve a same advantageous effect as that described above.
[0028] Embodiment 3.
Fig. 15 is a diagram schematically showing a short side portion of the air heat exchanger. Fig. 15 shows the short side portion 1 DS of the air heat exchanger 1 D, shown in Fig. 4, from a direction of an arrow C. As described above, the short side portion 1 DS of the air heat exchanger 1D is bent at an angle of 90 degrees from the long side portion 1 DL and extends along the lateral direction of the machine chamber 4. Accordingly, a tilt direction of the air heat exchanger 1D and a longitudinal direction of the corrugated fin 8 of the short side portion 1 DS of the air heat exchanger 1D coincide with each other, and condensed dew that is generated at the time of heating operation is possibly retained in a trough portion of the corrugated fin 8 in the manner shown in Fig. 15. The same can be said for the air heat exchanger 1A, the air heat exchanger 1 B, and the air heat exchanger 1C.
[0029] In contrast, in the case where the air heat exchanger 1D is formed in the manner shown in Fig. 9 or 10, the longitudinal direction of the corrugated fin 8 of the short side portion 1 DS of the air heat exchanger 1D intersects the tilt direction of the air heat exchanger 1D. Accordingly, because the air heat exchanger 1D is tilted, condensed dew flowing into the trough portion of the corrugated fin 8 of the short side portion 1 DS flows down without being retained. The same can be said for the air heat exchanger 1A, the air heat exchanger 1 B, and the air heat exchanger 1C.
[0030] Accordingly, in Embodiment 3, the corrugated fin 8 is formed in such a way that condensed dew is not retained on the short side portion even in a case where the air heat exchanger 1 is bent at an angle of 90 degrees in the manner shown in Fig. 4. Fig. 16 is a diagram schematically showing a mode of welding of the corrugated fin of the air heat exchanger of Embodiment 3. Fig. 16 schematically shows the air heat exchanger 1 of Embodiment 3, the air heat exchanger being cut at a position of a line D-D in Fig. 15 and seen from a direction of arrows. In Embodiment 3, the corrugated fin 8 is provided being tilted with respect to the longitudinal direction of the aluminum flat tube 7. The corrugated fin 8 is welded to the aluminum flat tube 7. When the air heat exchanger 1 formed in such a manner is bent at an angle of 90 degrees in the manner shown in Fig. 4 and is disposed being tilted in the manner shown in Fig. 2, a difference in the vertical direction is caused, at the short side portion of the air heat exchanger 1, between positions of end portions of the corrugated fin 8 in a lateral direction. Accordingly, condensed dew flowing into the trough portion of the corrugated fin 8 of the short side portion of the air heat exchanger 1 flows out of the corrugated fin 8 without being retained in the trough portion. According to Embodiment 3, condensed dew that is generated at the time of heating operation is not retained on the flat portion of the aluminum flat tube 7 or in the trough portion of the corrugated fin 8, and freezing of dew at the air heat exchanger 1 at the time of heating operation may be effectively prevented. Therefore, heating operation may be performed while maintaining high heat exchange capacity.
[0031] Embodiment 4.
The corrugated fin 8 of the air heat exchanger 1 is formed with a center portion in the lateral direction being higher than both end portions in the lateral direction.
The air heat exchanger formed in such a manner is bent at an angle of 90 degrees in the manner shown in Fig. 4, and is disposed being tilted in the manner shown in Fig. 2. A position of the center portion, in the lateral direction, of the corrugated fin is thus positioned higher than positions of both end portions in the lateral direction, at the short side portion of the air heat exchanger. As a result, condensed dew flowing into the trough portion of the corrugated fin at the short side portion of the air heat exchanger flows out of the corrugated fin without being retained in the trough portion.
Accordingly, an advantageous effect the same as that of Embodiment 3 may be obtained.
[0032] Embodiment 5.
An opening portion is formed in the corrugated fin 8 of the air heat exchanger 1 that is similar to the air heat exchanger 1 described above. The opening portion is formed with a size that does not affect heat exchange efficiency of the corrugated fin. The air heat exchanger 1 formed in such a manner is bent at an angle of 90 degrees in the manner shown in Fig. 4, and is disposed being tilted in the manner shown in Fig. 2. At the short side portion of the air heat exchanger, condensed dew that is generated at the time of heating operation falls in the vertical direction from the opening portion of the corrugated fin. Accordingly, an advantageous effect the same as that of Embodiment 3 may be obtained.
[0033] Embodiment 6.
The corrugated fin of the air heat exchanger that is similar to the air heat exchanger 1 described above is finished with water-repellent processing. The air heat exchanger formed in such a manner is bent at an angle of 90 degrees in the manner shown in Fig. 4, and is disposed being tilted in the manner shown in Fig. 2.
Condensed dew that is generated at the time of heating operation may be repelled at the short side portion of the air heat exchanger. Accordingly, an advantageous effect the same as that of Embodiment 3 may be obtained.
[0034] Embodiment 7.
Fig. 17 is a perspective view of a heat source unit according to Embodiment 7 of the present invention. Fig. 18 is a side view of the heat source unit of Embodiment 7. Fig. 19 is a diagram schematically showing arrangement of air heat exchangers in the heat source unit of Embodiment 7. Fig. 18 shows the heat source unit from a direction of an arrow C in Fig. 1. Fig. 19 shows a plurality of air heat exchanger from above the heat source unit. In Figs. 17 to 19, structural elements similar to the structural elements of Embodiment 1 are denoted by same reference signs as those in Figs. 1 to 4. A heat source unit 300 includes four air heat exchangers including an air heat exchanger 301A, an air heat exchanger 301 B, an air heat exchanger 301 C, and an air heat exchanger 301 D forming a refrigeration cycle on a heat source side, the cuboid machine chamber 4, and four fans including the fan 5A, the fan 5B, the fan 5C, and the fan 5D. The air heat exchanger 301A is the first heat exchanger of the present invention, the air heat exchanger 301 B is the second heat exchanger of the present invention, the air heat exchanger 301C is the third heat exchanger of the present invention, and the air heat exchanger 301 D is the fourth heat exchanger of the present invention. Additionally, in the following description, the air heat exchangers 301A, 301 B, 301 C, and 301 D may be collectively referred to as the air heat exchanger(s) 301.
[0035] The air heat exchanger 301 is a parallel-flow heat exchanger, and includes a pair of headers, a plurality of aluminum flat tubes, and a plurality of corrugated fins.
A specific configuration is similar to that of the air heat exchanger 1 of Embodiment 1 described with reference to Fig. 5. That is, the plurality of aluminum flat tubes are installed between the pair of headers, and end portions of the aluminum flat tubes are connected to the headers. The plurality of aluminum flat tubes are disposed, between the pair of headers, in parallel to one another while being spaced apart from one another, with flat portions of the aluminum flat tubes facing one another. The corrugated fins are provided between the facing flat portions of the plurality of aluminum flat tubes.
[0036] A side panel 310 is provided between the air heat exchanger 301A and the air heat exchanger 301C. A side panel 311 is provided between the air heat exchanger 301A and the air heat exchanger 301B. Additionally, a side panel (not shown) similar to the side panel 310 is also provided between the air heat exchanger 301B and the air heat exchanger 301 D. Furthermore, a side panel (not shown) similar to the side panel 311 is also provided between the air heat exchanger 301C and the air heat exchanger 301 D. A blocking panel 312 is provided between the air heat exchanger 301A and the side panel 311. The blocking panel 312 is also provided between the air heat exchanger 301B and the side panel 311. A blocking panel (not shown) similar to the blocking panel 312 is provided between the side panel between the air heat exchanger 301 C and the air heat exchanger 301 D, and the air heat exchanger 301 C. A blocking panel (not shown) similar to the blocking panel 312 is provided between the side panel between the air heat exchanger 301 C and the air heat exchanger 301 D, and the air heat exchanger 301 D. Additionally, the side panel 311 and the blocking panel 312 are omitted in Fig. 18.
[0037] As shown in Fig. 18, the air heat exchanger 301A and the air heat exchanger 3018 facing each other in the lateral direction of the machine chamber 4 are tilted in such a way that a gap between end portions on a side far from the machine chamber 4 is greater than a gap between end portions on a side close to the machine chamber 4. That is, the air heat exchanger 301A and the air heat exchanger 301B are tilted to form a V shape when seen from a side of the heat source unit 300. The air heat exchanger 301 C and the air heat exchanger 301 D facing each other in the lateral direction of the machine chamber 4 are also tilted to form a V shape. In Embodiment 7, a tilt angle 13 of the air heat exchanger 301A is 65 to 80 degrees.
The same can be said for tilt angles of the air heat exchanger 301 B, the air heat exchanger 301 C, and the air heat exchanger 301 D. [0038] As shown in Fig. 19, unlike the air heat exchangers 1 of Embodiment 1 and Embodiment 2 described above, the air heat exchanger 301 has a flat plate shape, and is not bent when seen from a direction perpendicular to the aluminum flat tube.
The air heat exchanger 301A and the air heat exchanger 301 B face each other in the lateral direction of the machine chamber 4, and the air heat exchanger 301 C and the air heat exchanger 301 D face each other in the lateral direction of the machine chamber 4. The air heat exchanger 301A and the air heat exchanger 301 C are arranged next to each other in the longitudinal direction of the machine chamber 4, and the air heat exchanger 301 B and the air heat exchanger 301 D are arranged next to each other in the longitudinal direction of the machine chamber.
[0039] Like the heat source unit 100 of Embodiment 1, the heat source unit 300 of Embodiment 7 is disposed in such a way that a direction of flow of air that is supplied intersects the long side portion of the aluminum flat tube of the air heat exchanger 1. Accordingly, air that is supplied is guided between the facing flat portions of a plurality of aluminum flat tubes, and is caused to flow along the width direction perpendicular to the longitudinal direction at the aluminum flat tubes.
[0040] According to Embodiment 7, the aluminum flat tube is used in the air heat exchanger 301. Accordingly, a heat exchange area the same as a heat exchange area when round tubes are used as the heat transfer tubes of the air heat exchanger may be secured by a smaller number of heat transfer tubes than when round tubes are used as the heat transfer tubes of the air heat exchanger. As a result, a manufacturing cost of the heat source unit 300 may be reduced. Furthermore, according to Embodiment 7, the air heat exchangers 301 facing each other in the lateral direction of the machine chamber 4 are tilted to form a V shape. Therefore, according to Embodiment 7, condensed dew that is generated at the time of heating operation flows down in the vertical direction without being retained on the flat portion of the aluminum flat tube. As a result, freezing of dew at the air heat exchanger 301 at the time of heating operation may be prevented, and heating operation may be performed while maintaining high heat exchange capacity.
[0041] Furthermore, when seen from a direction perpendicular to the aluminum flat tube, the air heat exchanger 301 of Embodiment 7 is not bent. In other words, a bending step is not required at the time of manufacturing the air heat exchanger 301. Accordingly, the air heat exchanger 301 may be easily manufactured.
[0042] Embodiment 8.
Fig. 20 is a diagram schematically showing heat source exchangers, where a heat source unit according to Embodiment 8 of the present invention is seen from above. Structural elements similar to the structural elements of Embodiment 2 and Embodiment 7 are denoted by same reference signs as those in Fig. 12 and Figs. 17 to 19. With a heat source unit 400 of Embodiment 8, the air heat exchanger 301A, the air heat exchanger 301 B, the air heat exchanger 301 C, and the air heat exchanger 301 D are disposed in the same manner as that shown in Fig. 19. Furthermore, the air heat exchanger 301A, the air heat exchanger 301 B, the air heat exchanger 301 C, and the air heat exchanger 301 D are disposed being tilted in the same manner as in Fig. 18.
[0043] The spray pipes 18 and the spray nozzles 19 are disposed between the air heat exchanger 301A and the air heat exchanger 301B facing each other in the lateral direction of the machine chamber 4, and between the air heat exchanger 301 C and the air heat exchanger 301 D facing each other in the lateral direction of the machine chamber 4. That is, as in Embodiment 2, the spray pipes 18 and the plurality of spray nozzles 19 are installed in a square space formed by the air heat exchanger 301A, the air heat exchanger 301 B, the air heat exchanger 301 C, and the air heat exchanger 301 D. The two spray pipes 18 are disposed in parallel to each other in the longitudinal direction of the machine chamber 4. The plurality of spray nozzles 19 are attached to the two spray pipes 18 in a manner facing the air heat exchanger 301A, the air heat exchanger 301 B, the air heat exchanger 301 C, and the air heat exchanger 301D. Water that is supplied to the spray pipes 18 is sprayed onto the air heat exchanger 301A, the air heat exchanger 301 B, the air heat exchanger 301 C, and the air heat exchanger 301 D through the spray nozzles 19.
[0044] At the time of execution of the spray operation, when water is supplied to the spray pipes 18 and the supplied water is sprayed from the spray nozzles 19 onto the air heat exchangers 301, water drops hit end portions, of the aluminum flat tubes, on sides where the spray pipes 18 are disposed. In Embodiment 8, as in Embodiment 7, the air heat exchangers 301 are disposed being tilted into a V shape, and the aluminum flat tubes are also tilted. Accordingly, water drops flow on the flat portions of the aluminum flat tubes and flow down in the vertical direction from opposite end portions after hitting the end portions, of the aluminum flat tubes, on the sides where the spray pipes are disposed. Accordingly, as in Embodiment 2, a high spraying effect may be obtained compared to a case where the air heat exchangers 1 are not tilted, and the cooling performance of the heat source unit 400 may be further increased.
[0045] The air heat exchangers 301 of Embodiment 7 and Embodiment 8 are, but not limited to, parallel-flow heat exchangers. A fin-and-tube heat exchanger where a plurality of plate-shaped fins are disposed between a pair of headers and aluminum flat tubes penetrate the plurality of fins may be alternatively used as the air heat exchanger.
