    • <Overview of heat pump cycle device>
  • In this embodiment, a heat pump cycle device is exemplified as an air conditioner. Fig. 1 is a schematic configuration diagram of a heat pump cycle device according to this embodiment. As an example, Fig. 1 shows a heat pump hot water heating device as an air conditioner. As shown in Fig. 1, a heat pump cycle device 1 includes an outdoor unit 10 and an indoor unit 90.
  • The outdoor unit 10 of the heat pump cycle device 1 incudes a compressor 110, a four-way valve 120, a water-refrigerant heat exchanger 130, a water pump (circulation pump) 130, an expansion valve 150, an outdoor heat exchanger 160, an accumulator 170, an outside temperature sensor 180, a blower 190, and a control unit 300. In the outdoor unit 10, the compressor 110, the four-way valve 120, the water-refrigerant heat exchanger 130, the expansion valve 150, the outdoor heat exchanger (air-refrigerant heat exchanger) 160, and the accumulator 170 are connected in order by a refrigerant pipe 19, thereby forming a refrigerant circuit 1c in the heat pump cycle device 1. Note that the blower 190 includes a propeller fan and a motor that drives the propeller fan.
  • The indoor unit 90 of the heat pump cycle device 1 includes an indoor unit 900. In the indoor unit 90, the indoor unit 900, the water-refrigerant heat exchanger 130, and the water pump 140 are connected in series by a water pipe 95, thereby forming a hot water circuit 1h in the heat pump cycle device 1.
    • <Configuration of refrigerant circuit>
  • The respective devices forming the refrigerant circuit 1c will be described in more detail.
  • The compressor 110 is driven by a motor (not shown) whose rotation speed is controlled by an inverter. The compressor 110 is a variable capacity compressor whose operating capacity can be varied. The compressor 110 compresses the sucked low-pressure gas refrigerant and supplies a high-pressure gas refrigerant. The four-way valve 120 is a flow path switching valve for switching the refrigerant circulation direction in the refrigerant circuit 1c. The water-refrigerant heat exchanger 130 is, for example, a plate-type heat exchanger. The water-refrigerant heat exchanger 130 functions as a user-side heat exchanger, exchanging heat between the refrigerant that flows through the refrigerant pipe 19 and flows into the water-refrigerant heat exchanger 130 and water that flows through the water pipe 95 and flows into the water-refrigerant heat exchanger 130.
  • The expansion valve 150 is an electronic expansion valve in which the degree of opening of the valve is controlled by pulse control of a stepping motor. The expansion valve 150 reduces the pressure (expands) the liquid refrigerant passing through the expansion valve 150. The outdoor heat exchanger 160 is, for example, a fin-tube heat exchanger. The outdoor heat exchanger 160 functions as a heat source side heat exchanger, exchanging heat between the refrigerant that flows through the refrigerant pipe 19 and flows into the outdoor heat exchanger 160 and the outside air (outdoor air) taken in by the rotation of the blower 190. The accumulator 170 separates the refrigerant flowed in from the four-way valve 120 into a gas refrigerant and a liquid refrigerant, and only the gas refrigerant is sucked into the compressor 110.
  • The blower 190 is disposed, inside a housing 101, in the vicinity of the outdoor heat exchanger 160 disposed inside the housing 101. The blower 190 takes in outside air from a suction port (described below) of the outdoor unit 10 into the outdoor unit 10, and releases, from an air outlet (described below) to the outside of the outdoor unit 10, the outside air that has exchanged heat with the refrigerant in the outdoor heat exchanger 160.
  • The outside temperature sensor 180 is provided in the vicinity of the outdoor heat exchanger 160, facing the outside of the housing 101. The outside temperature sensor 180 detects the temperature of the outside air taken into the outdoor unit 10 by the rotation of the blower 190.
    • <Configuration of hot water circuit>
  • In the outdoor unit 10, in addition to the refrigerant pipe 19, the water pipe 95 is connected to the water-refrigerant heat exchanger 130. The indoor unit 900 and the water pump 140 are sequentially connected to the water pipe 95. The water pump 140 is driven by a motor with a fixed rotation speed or a motor with a variable rotation speed. As a result, in the hot water circuit 1h, water circulates in the direction indicated by a solid arrow. For example, the water circulates through the water pump 140, the indoor unit 900, the water-refrigerant heat exchanger 130, and the water pump 140 again in this order, via the water pipe 95. The indoor unit 900 is, for example, a terminal for heating the room, such as a floor heating device and a radiator. That is, the water circulating through the hot water circuit 1h dissipates heat in the indoor unit 900, thereby heating the air-conditioned space in which the indoor unit 90 is installed.
    • <Control unit>
  • The control unit 300 includes a CPU that performs calculation and transmits information, a storage unit that stores various programs relating to the operation control of the heat pump cycle device 1, a request (such as a set temperature) regarding the operation set by a user in the indoor unit 900, a set temperature set by the indoor unit 900, values detected by various sensors provided in the refrigerant circuit 1c or the hot water circuit 1h, and the like, a sensor input unit that inputs detection values of various sensors provided in the refrigerant circuit 1c or the hot water circuit 1h, a reception unit that receives a signal transmitted from a remote control (not shown) for operating the indoor unit 90, and the like. The CPU, the storage unit, the sensor input unit, the reception unit, and the like are mounted on, for example, a circuit board (circuit board). The control unit 300 controls the compressor 110, the four-way valve 120, the water pump 140, the expansion valve 150, and the like on the basis of the values detected by various sensors or various requests regarding the operation.
  • Further, the outdoor unit 10 is divided into a heat exchange chamber 10H and a machine chamber 10M by a partition plate 20 (Fig. 3). In the outdoor unit 10, the outdoor heat exchanger 160 and the blower 190 are disposed in the heat exchange chamber 10H of the outdoor unit 10. The compressor 110, the four-way valve 120, the water-refrigerant heat exchanger 130, the water pump 140, the expansion valve 150, and the accumulator 170 are disposed in the machine chamber 10M of the outdoor unit 10 (not shown in Fig. 3).
  • As shown in Fig. 3, the outside temperature sensor 180 is disposed in the vicinity of the outdoor heat exchanger 160 on the side opposite to the blower 190. For example, the outside temperature sensor 180 is disposed in a suction port 103 through which outside air is blown into the outdoor unit 10 by the blower 190, behind the outdoor heat exchanger 160. The control unit 300 may be disposed in the heat exchange chamber 10H of the outdoor unit 10 or in the machine chamber 10M. Further, the control unit 300 may be disposed across the machine chamber 10M and the heat exchange chamber 10H. Fig. 1 shows an example in which the control unit 300 is disposed across the machine chamber 10M and the heat exchange chamber 10H.
    • <Operations of refrigerant circuit and hot water circuit>
  • The operation of the heat pump cycle device 1 will be described with reference to Fig. 1.
    • <Heating operation>
  • When the heat pump cycle device 1 performs a heating operation, the four-way valve 120 is operated to set the refrigerant circuit 1c to a heating cycle. When the compressor 110 is driven in this state, the refrigerant flows through the refrigerant circuit 1c in the direction indicated by the solid arrow. The refrigerant supplied from the compressor 110 flows through the refrigerant pipe 19 and flows into the water-refrigerant heat exchanger 130 via the four-way valve 120.
  • The refrigerant that has flowed into the water-refrigerant heat exchanger 130 exchanges heat with the water that has circulated through the hot water circuit 1h and flowed into the water-refrigerant heat exchanger 130, and is condensed. The refrigerant flowing out from the water-refrigerant heat exchanger 130 to the refrigerant pipe 19 is reduced in pressure when passing through the expansion valve 150 and flows into the outdoor heat exchanger 160.
  • The refrigerant that has flowed into the outdoor heat exchanger 160 exchanges heat with outside air and evaporates. The refrigerant flowing out from the outdoor heat exchanger 160 to the refrigerant pipe 19 is sucked into the compressor 110 via the four-way valve 120 and the accumulator 170 and is compressed again.
  • Meanwhile, in the hot water circuit 1h, the water pump 140 is driven to cause water to flow through the hot water circuit 1h in the direction indicated by the solid arrow. The water that has flowed through the water pipe 95 and flowed into the water-refrigerant heat exchanger 130 exchanges heat with the refrigerant and is heated by the refrigerant, thereby becoming hot water. This hot water flows into the indoor unit 900. The hot water flows through the indoor unit 900, thereby heating the room in which the indoor unit 900 is installed.
    • <Defrosting operation and cooling operation>
  • When the heat pump cycle device 1 performs the heating operation, frost forms on the outdoor heat exchanger 160 that functions as an evaporator. In this case, the outdoor unit 10 is capable of performing a defrosting operation of the outdoor heat exchanger 160.
  • For example, when the heat pump cycle device 1 performs the defrosting operation, the four-way valve 120 is operated to switch the flow direction of the refrigerant in the refrigerant circuit 1c such that the outdoor heat exchanger 160 functions as a condenser. That is, the refrigerant circuit 1c is set to a cooling cycle. When the compressor 110 is driven in this state, the refrigerant flows through the refrigerant circuit 1c in the direction indicated by a broken arrow. The refrigerant supplied from the compressor 110 flows through the refrigerant pipe 19 and flows into the outdoor heat exchanger 160 via the four-way valve 120. At this time, the blower 190 is stopped.
  • The refrigerant that has flowed into the outdoor heat exchanger 160 melts the frost that has formed on the outdoor heat exchanger 160 by the heat of the refrigerant. The refrigerant flowing out from the outdoor heat exchanger 160 to the refrigerant pipe 19 passes through the expansion valve 150 in which the degree of opening is full, flows into the water-refrigerant heat exchanger 130, exchanges heat with the water that has circulated through the hot water circuit 1h and flowed into the water-refrigerant heat exchanger 130, and evaporates. The refrigerant flowing out from the water-refrigerant heat exchanger 130 to the refrigerant pipe 19 is sucked into the compressor 110 via the four-way valve 120 and the accumulator 170 and is compressed again.
  • Further, the outdoor unit 10 can be applied to not only the heating operation but also the cooling operation. When the outdoor unit 10 is applied to a heat pump hot-and-cold water air conditioner, the above cooling cycle is applied. In this case, the cold refrigerant that has released heat in the outdoor heat exchanger 160 flows into the water-refrigerant heat exchanger 130, and exchanges heat with the water in the hot water circuit 1h flowing through the water-refrigerant heat exchanger 130, thereby turning the water in the hot water circuit 1h into cool water. As a result, the cool water flows through the indoor unit 900, and the cool water circulating the hot water circuit 1h absorbs heat in the indoor unit 900, thereby cooling the air-conditioned space in which the indoor unit 90 is installed.

  • The blower 190 is disposed to face the first heat exchange unit 160a of the outdoor heat exchanger 160 in the front-and-rear direction and in proximity to the air outlet 102. As the blower 190 rotates, outside air flows into the heat exchange chamber 10H from the suction port 103, this outside air passes through the outdoor heat exchanger 160, and the outside air and the refrigerant flowing through the outdoor heat exchanger 160 exchange heat. The outside air that has passed through the outdoor heat exchanger 160 is discharged from the heat exchange chamber 10H via the air outlet 102 by the rotation of the blower 190.

Further, parts constituting the hot water circuit 1h, such as the water-refrigerant heat exchanger 130 and the water pump 140, are disposed in the machine chamber 10M. These parts are connected by the water pipe 95. Further, the rear portion 101ba of the rear panel 101b is provided with an inflow port 91 through which the water from the indoor unit 900 flows into the water-refrigerant heat exchanger 130, and an outflow port 92 through which the water flows out from the water-refrigerant heat exchanger 130 to the indoor unit 900. The water pipe 95 is connected to the inflow port 91 and the inflow port 92.
  • The partition plate 20 includes a first portion 21 and a second portion 22 and is fixed to the bottom plate 101d. The partition plate 20 is provided with a bent portion 25 between the first portion 21 and the second portion 22 such that the first portion 21 and the second portion 22 intersect with each other. The partition plate 20 includes the first portion 21 and the second portion 22 with the bent portion 25 sandwiched therebetween. The first portion 21 is disposed along the direction intersecting the front-and-rear direction. The second portion 22 is disposed along the front-and-rear direction. The angle between the first portion 21 and the second portion 22 is an obtuse angle. The first portion 21 is disposed closer to the outdoor heat exchanger 160 than the second portion 22. The angle between the first portion 21 and the outdoor heat exchanger 160 is an acute angle. Part of the space of the heat exchange chamber 10H is formed between the first portion 21 and the outdoor heat exchanger 160. The width of the first portion 21 in the above intersecting direction is narrower than the width of the second portion 22 in the front-and-rear direction.
    • <Part arrangement in outdoor unit>
  • Fig. 7 and Fig. 8 are each a schematic top view showing a machine chamber of the outdoor unit. In Fig. 7, respective parts disposed in the machine chamber 10M are omitted. Further, in Fig. 7 and Fig. 8, the recessed portion 28 of the partition plate 20 described below is omitted. Further, Fig. 9 and Fig. 10 are each a schematic perspective view showing a positional relationship between the partition plate and the compressor. Fig. 9 shows the state as viewed from the side of the machine chamber 10M, and Fig. 10 shows the state as viewed from the side of the heat exchange chamber 10HM.
  • As described above, the inside of the housing 101 of the outdoor unit 10 is divided by the partition plate 20 into the heat exchange chamber 10H on the left side as viewed from the front surface and the machine chamber 10M on the right side. Further, as shown in Fig. 7, when the inside of the machine chamber 10M of the outdoor unit 10 is in a plan view, the machine chamber 10M is divided by a boundary line (broken line) 10BL into two sections (two spaces) in the right-and-left direction. Here, the "plan view" means a case where the outdoor unit 10 is cut in the horizontal direction and the outdoor unit 10 is viewed from directly above, e.g., a case where the outdoor unit 10 is cut by a plane perpendicular to the Z axis that is the up-and-down direction of the machine chamber 10M and the outdoor unit 10 is viewed from directly above (in the Z-axis direction). This boundary line 10BL a virtual line segment created when the virtual plane 10ZY shown in Fig. 4 is in a plan view, i.e., cut by a plane perpendicular to the Z axis. In other words, when the boundary lines 10BL are connected continuously in the up-and-down direction, the plane 10ZY shown in Fig. 4 is formed. In this way, the machine chamber 10M has a virtual plane 10fa (plane surrounded by the boundary line 10BL and a dot-dash line 10LA) and a plane 10fb (plane surrounded by the boundary line 10BL and a dot-dash line 10LB). The plane 10fa and the plane 10fb are each a virtual plane at an arbitrary position of the machine chamber 10M in the up-and-down direction.
  • The machine chamber 10M having the two planes 10fa and 10fb is divided into the left side section (space) to which the plane 10fa belongs and the right side section (space) to which the plane 10fb belongs, as shown in Fig. 8. In this Example, the left side section (space) is referred to as a first section 10A, and the right side section (space) is referred to as a second section 10B. The inside of the machine chamber 10M is divided into the first section 10A and the second section 10B each having a predetermined height, in order from the side of the partition plate 20. At this time, the compressor 110 and the accumulator 170 are disposed in the first section 10A, and the water-refrigerant heat exchanger 130 is disposed in the second section 10B. Further, the water pump 140 is disposed in the second section 10B. In this Example, each of the first section 10A and the second section 10B has a length in the front-and-rear direction, which is longer than the length in the right-and-left direction, and has a longitudinally elongated shape in a plan view. Note that the partition plate 20 is disposed such that the first portion 21 intersects with the second portion 22 from the bent portion 25. The length in the front-and-rear direction of the first section 10A on the side of the second portion 22 of the partition plate 20 is shorter than the length of the virtual plane 10fa in the front-and-rear direction. By forming part of the first section 10A shorter in the front-and-rear direction, a space in which an end portion of the outdoor heat exchanger 160 adjacent to the first portion 21 of the partition plate 20 is formed. This allows the length in the circumferential direction (the length in the right-and-left direction and the length in the up-and-down direction) of the outdoor heat exchanger 160 to be longer.
  • In the first section 10A, the accumulator 170 and the compressor 110 are aligned in the front-and-rear direction. For example, in the first section 10A, the compressor 110 is disposed on the front side of the housing 101 and the accumulator 170 is disposed on the rear side of the housing 101. Further, the accumulator 170 and the compressor 110 are aligned along the second portion 22 of the partition plate 20. Further, in the second section 10B, the water-refrigerant heat exchanger 130 and the water pump 140 are aligned in the front-and-rear direction. For example, in the second section 10B, the water pump 140 is disposed on the front side of the housing 101 and the water-refrigerant heat exchanger 130 is disposed on the rear side of the housing 101. Further, the water-refrigerant heat exchanger 130 and the water pump 140 are aligned in the direction in which the accumulator 170 and the compressor 110 are aligned. In other words, the water-refrigerant heat exchanger 130 and the water pump 140 are aligned in the front-and-rear direction.
  • As shown in Fig. 9, the compressor 110 includes, for example, a columnar outer shell 110a that houses a motor and a compression mechanism (not shown) and a support portion 110b that supports the compressor 110 at the lower part of the outer shell. The support portion 110b includes a stage 110s having a triangular plane shape, and a through hole is provided at each of three corner portions. Part of each of fastening members 110ff1, 110ff2, and 110ff3 (e.g., a bolt described below) is inserted into the through hole. The compressor 110 is fixed to the bottom plate 101d by three fixing portions 110f (a fixing portion 110f1, a fixing portion 110f2, and a fixing portion 110f3). The fixing portions 110f include, for example, each of the fastening members 110ff1, 110ff2, and 110ff3, each including a bolt, a nut, and cylindrical elastic rubber that suppresses the transmission of vibration, through holes provided in the stage 110s, through which the respective fastening members pass, and a through hole provided in the bottom plate 101d. In the compressor 110, the two fixing portions 110f1 and 110f2 of the three fixing portions 110f are disposed along the second portion 22 of the partition plate 20.
  • As described above, in this embodiment, the compressor 110 and the accumulator 170 that form the refrigerant circuit 1c, and the water-refrigerant heat exchanger 130 and the water pump 140 that form the hot water circuit 1h are disposed in the machine chamber 10M of the housing 101. Further, the machine chamber 10 is divided into the first section 10A and the second section 10B, which are longitudinally long. Then, the compressor 110 and the accumulator 170 are disposed in the first section 10A such that they are aligned in the front-and-rear direction, and the water-refrigerant heat exchanger 130 and the water pump 140 are disposed in the second section 10B such that they are aligned in the front-and-rear direction. That is, the compressor 110 and the accumulator 170 are disposed to be aligned in the front-and-rear direction inside the first section 10A that is long in the front-and-rear direction. Further, the water-refrigerant heat exchanger 130 and the water pump 140 are disposed to be aligned in the front-and-rear direction inside the second section 10B that is long in the front-and-rear direction.
  • By disposing the compressor 110 and the accumulator 170 such that they are aligned in the front-and-rear direction, it is possible to reduce the length of the first section 10A in the right-and-left direction. By disposing the compressor 110 on the front side, the two fixing portions 110f1 and 110f3 of the fixing portions 110f of the compressor 110 can be seen from the front side. The compressor 110 is fixed to the bottom plate 101d by the three fastening members 110ff1,110ff2, and 110ff3 inserted through the support portion 110b. When fixing the compressor 110 to the bottom plate 101d, a worker can access, from the front side, the two fastening members 110ff1 and 110ff3 disposed on the front side, so that the compressor 110 can be easily attached and detached (for example, the nut can be easily tightened or loosened by the worker). Meanwhile, by disposing the accumulator 170 on the rear side, the distance between the accumulator 170 and the end portion of the outdoor heat exchanger 160 on the side of the partition plate 20 becomes shorter. This shortens the length of the refrigerant pipe and reduces the volume of the arrangement space of the refrigerant pipe in the machine chamber 10M. Further, in this Example, the four-way valve 120 is provided on the rear side of the accumulator 170 (Fig. 6). The four-way valve 120 is a valve that switches the flow path of the high-temperature and high-pressure refrigerant supplied from the compressor 110. For example, in the case of generating hot water, the refrigerant supplied from the compressor is caused to flow through the water-refrigerant heat exchanger 130.
  • Further, by disposing the water-refrigerant heat exchanger 130 and the water pump 140 such that they are aligned in the front-and-rear direction, it is possible to reduce the length of the second section 10B in the right-and-left direction. By disposing the water pump 140 on the front side, a worker can easily access the water pump 140 from the front surface. Meanwhile, by disposing the water-refrigerant heat exchanger 130 on the rear side, the distance between the water-refrigerant heat exchanger 130 and the four-way valve becomes shorter. This reduces the length of the refrigerant pipe when generating hot water and allows the temperature of the refrigerant to be prevented from dropping before the refrigerant flows into the water-refrigerant heat exchanger 130.
  • With such arrangement, even if the water-refrigerant heat exchanger 130 is disposed in the housing 101 of the outdoor unit 10, it is possible to effectively utilize the disposition regions of the compressor 110 and the accumulator 170 and the disposition regions of the water-refrigerant heat exchanger 130 and the water pump 140, and prevent the housing 101 from becoming larger.
  • Further, in this embodiment, the water-refrigerant heat exchanger 130 and the water pump 140 are disposed in the second section 10B on the side of the service panel 101s. As a result, even after the compressor 110 and the accumulator 170 are mounted in the machine chamber 10M, the water-refrigerant heat exchanger 130 and the water pump 140 that form the hot water circuit 1h can be mounted independently of the refrigerant circuit 1c, making it easier to mount the water-refrigerant heat exchanger 130 and the water pump 140.
  • Further, in this embodiment, the two fixing portions 110f (the fixing portion 110f1 and the fixing portion 110f2) of the three fixing portions 110f of the compressor 110 are disposed along the partition plate 20. This allows the distance between the partition plate 20 and the remaining fixing portion 11f3 to be reduced. That is, the compressor 110 can be disposed close to the partition plate 20 and the length of the first section 10A in the right-and-left direction can be reduced. Therefore, it is possible to prevent the housing 101 from becoming larger. Further, the arrangement of the parts other than the compressor 110 is less likely to be hindered by the fixing portions 110f of the compressor 110 and the degree of freedom of the arrangement of the parts other than the compressor 110 is improved.
  • The partition plate 20 includes the first portion 21, the second portion 22, and the bent portion 25. The bent portion 25 is sandwiched between the first portion 21 and the second portion 22, and provided between the first portion 21 and the second portion 22 such that the first portion 21 and the second portion 22 intersect with each other. The first portion 21 is disposed along the direction intersecting the front-and-rear direction of the housing 101. The second portion 22 is disposed along the front-and-rear direction of the housing 101. The width of the first portion 21 is narrower than the width of the second portion 22.
  • Further, for example, the partition plate 20 has a projecting portion 200 that protrudes toward the heat exchange chamber 10H. The projecting portion 200 includes a first projecting portion 210 and a second projecting portion 220. The first projecting portion 210 is provided to the first portion 21, and the second projecting portion 220 is provided to the second portion 22. The portion of the second projecting portion 220 on the bottom plate side faces the fixing portion 110f of the compressor 110.
  • The first projecting portion 210 is formed in the first portion 21 of the partition plate 20. The first projecting portion 210 is provided on the lower side of the first portion 21. The first projecting portion 210 is formed in, for example, a frustum shape, and protrudes from a base portion 210b of the first portion 21 toward the heat exchange chamber 10H. By providing the first projecting portion 210 that protrudes toward the heat exchange chamber 10H to the partition plate 20, it is possible to ensure a distance between the refrigerant pipe or the four-way valve connected to the compressor 110 and the partition plate 20. As a result, when a worker installs the refrigerant pipe or the four-way valve in the heat exchange chamber 10H, the installation work can be easily performed because the contact with the partition plate 20 can be avoid.
  • The second projecting portion 220 is formed in the second portion 22 of the partition plate 20. The second projecting portion 220 is provided on the lower side of the second portion 22. The second projecting portion 220 is formed in, for example, a frustum shape, and protrudes from a base portion 220b of the second portion 22 toward the heat exchange chamber 10H. In the machine chamber 10M, the second projecting portion 220 faces the compressor 110.
  • By providing such a projecting portion that protrudes toward the heat exchange chamber 10H to the partition plate 20, it is possible to ensure a distance between the compressor 110 and the partition plate 20. As a result, when a worker installs the compressor 10H in the heat exchange chamber 10H, the support portion supporting the compressor 110 can be brought close to the partition plate 20 while avoiding the contact between the outer shell of the compressor and the partition plate 20. Specifically, since the support portion includes the stage 110s having a triangular plane shape, one side surface of this stage 110s can be brought close to the lower end side of the partition plate 20. Each of the corner portions of the stage 110s is provided with a fixing portion. Therefore, the portion of the partition plate 20 corresponding to the fixing portion protrudes toward the heat exchange chamber 10H. Further, one end side of the first section 10A in the right-and-left direction protrudes toward the heat exchange chamber 10H. As a result, it is possible to prevent the housing 101 from becoming larger while ensuring the length of the first section 10A in the right-and-left direction.
  • Further, the partition plate 20 has an opening 26 on the side of the bottom plate 101d of the second portion 22. The opening 26 is provided, for example, on the side of the bottom plate 101d of the second projecting portion 220. The opening 26 is closed by a lid portion 27. By opening the lid portion 27 toward the heat exchange chamber 10H, at least one (the fixing portion 110f2) of the fixing portions 110f of the compressor 110 can be seen from the heat exchange chamber 10H toward the machine chamber 10M. The compressor 110 is fixed to the bottom plate 101d by the three fixing portions 110f inserted through the support portion. When the compressor 110 is attached/detached to/from the bottom plate 101d, for example, the compressor 110 can be easily fixed through the opening 26 by providing such an opening 26 to the partition plate 10. Therefore, even if the fixing portions 110f (the fixing portion 110f1 and the fixing portion 110f2) are disposed along the partition plate 20 in order to prevent the housing 101 from becoming larger, the fixing portion 110f located on the rear side of the machine chamber 10M can be accessed without removing the partition plate 20, it is possible to easily attach/detach the compressor 110. Note that even if the partition plate 20 is not provided with a projecting portion, the partition plate 20 can have the opening 26.
  • Further, the partition plate 20 has the recessed portion 28 that is recessed toward the machine chamber 10M. For example, the recessed portion 28 is provided in the upper part of the partition plate 20, and includes a bottom portion 281, a side portion 282, and a side portion 283. The side portion 283 is connected to the bottom portion 281 and the side portion 282. The bottom portion 281 intersects with the side portion 282 and the side portion 283. The side portion 283 intersects with the side portion 282. The effect obtained by providing the recessed portion 28 will be described below.
  • Fig. 11 and Fig. 12 are each a schematic perspective view showing the machine chamber of the outdoor unit. Fig. 12 shows the state in which the control unit 300 and a terminal block 350 shown in Fig. 11 are removed. In Fig. 11 and Fig. 12, the plane 10ZY shown in Fig. 4 is shown in the machine chamber 10M. In Fig. 11 and Fig. 12, dots of the plane 10ZY are partially added in order to show the inside of the machine chamber 10M. Further, Fig. 13 is a schematic perspective view showing a control unit and a terminal block disposed in the housing.
  • As described above, the machine chamber 10M is divided by the boundary line 10BL (Fig. 7) into the two sections (the first section 10A and the second section 10B) in the right-and-left direction. The control unit 300 in the outdoor unit 10 is provided in the upper part on the front side of the first section 10A of the machine chamber 10M. Further, the terminal block 350 to which electric power is supplied from the outside of the outdoor unit 10 is provided in the upper part of the second section 10B of the machine chamber 10M. Note that the terminal block 350 is disposed on the rear side of the control unit 300 in the front-and-rear direction.
  • The control unit 300 includes a first control board 310 and a second control board 320. The first control board 310 is, for example, an intelligent power module (IPM) and controls the compressor 110, the blower 190, and the like. In this Example, the first control board 310 is disposed such that the part mounting surface on which an electronic part such as an IPM is mounted faces downward in the up-and-down direction. Further, the first control board 310 is disposed such that the longitudinal direction is along the right-and-left direction. Therefore, in this Example, the left end portion of the first control board 310 in the right-and-left direction is disposed in the heat exchange chamber 10H beyond the partition plate 22, and the right end portion of the first control board 310 is disposed in the second section 10B beyond the first section 10A. The second control board 320 controls, for example, the water pump 140. The second control board 320 is disposed such that the part mounting surface faces forward. Further, the holding portion of the second control board 320 is fixed to the partition plate 20. In this Example, the entire second control board 320 is housed in the first section 10A. The first control board 310 is disposed above the second control board 320. The height of the second control board 320 from the bottom plate 101d is substantially the same as the height of the terminal block 350 from the bottom plate 101d. Further, the side surface on the machine chamber side of the side portion 282 forming the recessed portion 28 abuts on a holding portion 312 of the first control board 310 (Fig. 13). Part of the holding portion of the first control board 310 is supported by the side portion 282.
  • In this way, the control unit 300 and the terminal block 350 are disposed at substantially the same height from the bottom plate 101d without being stacked in the up-and-down direction in the machine chamber 10M. Specifically, the height of the second control board 320 from the bottom plate 101d is substantially the same as the height of the terminal block 350 from the bottom plate 101d. This prevents the housing 101 from becoming larger in the up-and-down direction. Further, the control unit 300 is disposed on the side of the first section 10A and above the compressor. Meanwhile, the terminal block 350 is disposed on the side of the second section 10B and above the water-refrigerant heat exchanger 130. In this way, by disposing the control unit 300 and the terminal block 350 on the side of different sections, the heights from the bottom plate 101d can be made substantially the same, and the housing 101 is prevented from becoming larger in the up-and-down direction. Further, the second control board 320 that controls the water pump 140 and the water pump 140 are disposed to face the rear surface of the front portion 101ra of the right side panel. As a result, when a worker accesses the water pump 140 from the front surface by removing the right side panel, he/she can access the second control board 320 simultaneously. Further, the terminal block 350 is disposed to face the rear surface of the service panel 101s. As a result, by removing the service panel 101s, the worker can connect the power line for supplying electric power to the outdoor unit 10 to the terminal block 350.
  • Further, part of the first control board 310 protrudes from the first section 10A of the machine chamber 10M to the heat exchange chamber 10H. A heat dissipation portion 311 such as a heat sink is disposed on the first control board 310 protruding to the heat exchange chamber 10H (Fig. 13). As a result, the heat dissipation portion 311 is exposed to the outside air in the heat exchange chamber 10H, and the first control board 310 is efficiently cooled.
  • Fig. 14 is a schematic front view showing a positional relationship between the blower and the first control board in the heat exchange chamber.
  • In the outdoor unit 10, the blower 190 is closer to the top plate 101u than the bottom plate 101d. For example, a distance d1 between a central axis 190c of the blower 190 to the bottom plate 101d is longer than a distance d2 between the central axis 190c and the top plate 101u. Further, the heat dissipation portion 311 of the first control board 310 is disposed on the side of the blower 190.
  • With such arrangement, since the blower 190 is closer to the top plate 101u than the bottom plate 101d, the distance between the blower fan and the heat dissipation portion 311 becomes shorter without increasing the diameter of the blower fan (propeller) of the blower 190, the heat dissipation portion 311 is efficiently cooled, and the first control board 310 is efficiently cooled.
  • Fig. 15 is a schematic top view showing the state in which a partition plate having a recessed portion is disposed in the housing.
  • The recessed portion 28 of the partition plate 20 is located above the accumulator 170. When the partition plate 20 in the vicinity of the suction port 103 has such a recessed portion 28, it is possible to increase the volume of the heat exchange chamber 10H without changing the size of external size of the housing 101. Specifically, the space above the accumulator 170 disposed in the first section 10A of the machine chamber 10M is included in the heat exchange chamber 10H. As a result, the ventilation resistance above the accumulator 170 is reduced and the outside air flowing into the heat exchange chamber 10H easily passes above the accumulator 170. Therefore, the amount of air passing through the upper part of the heat exchanger portion located on the rear side of the accumulator 170, of the heat exchanger 160, increases, and the heat exchange rate of the entire outdoor heat exchanger 160 is improved. Further, a larger amount of outside air hits the heat dissipation portion 311 of the first control board 310, thereby further efficiently cooling the first control board 310.
  • Although embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-mentioned embodiments and various modifications can be made. For example, although a heat pump hot water heating device has been described as an example of a heat pump cycle device, the present invention is not limited thereto, and this device can also be applied to a heat pump cycle device such as a heat pump hot water supply device and a heat pump hot-and-cold water air conditioner. The respective embodiments are not limited to the independent embodiments and can be combined with each other if technically possible.
