Problems solved by technology

[0007] However, in a conventional refrigerator having a power supply device, if a heat exchanger configured to perform heat exchange between refrigerant and water is used as the heat source side heat exchanger, it is no longer necessary to blow air to the heat source side heat exchanger. Air supply device, so it cannot cool the power supply device

example 2—

[0079] Modification 2 of the embodiment will be described. In this Modification 2, such as Figure 4 As shown, the heat dissipation device 32 is exposed downstream of the air supply device 26 in the air passage 21 . In addition, the power distribution box 23 communicates with the downstream of the air blower 26 in the air passage 21 . In addition, in the case 14 , a discharge passage 38 connecting the distribution box 23 and the air outlet 16 is formed by the partition wall 36 .

[0080] In Modification 2, the air blown from the blower 26 contacts the heat sink 32 to cool the heat sink 32 . That is, the positive pressure of the air blower 26 is used to cool the heat sink 32 . In addition, a part of the air blown from the air blower 26 flows into the air guide passage 37 , and the assembled substrate 34 is cooled in the air guide passage 37 and the power distribution box 23 . The air heated by the assembled substrate 34 is guided to the air outlet 16 through the discharge p...

Abstract

A refrigeration system (10) includes: a refrigerant circuit (11) performing a vapor compression refrigeration cycle by including a compressor (30), a utilization side heat exchanger (24) configured to allow refrigerant to perform heat exchange with air, and a heat-source side heat exchanger (25) configured to allow refrigerant to perform heat exchange with water; and a casing (14) housing the utilization side heat exchanger (24). The casing (14) contains a power supply (31) including a power semiconductor device and configured to supply electric power to the compressor (30), and also contains a cooler (19) configured to cool the power supply (31) by supplying air to the power supply (31).

Description

technical field [0001] The present invention relates to a refrigeration device having a power supply device for supplying power to a compressor. Background technique [0002] Heretofore, a refrigeration device having a power supply device (such as an inverter device) for supplying power to a compressor has been known. Power supply devices are equipped with power semiconductors that generate a large amount of heat. For example, Patent Document 1 discloses an air conditioner that cools a power supply device with air sent to an outdoor heat exchanger (heat source side heat exchanger) by an outdoor fan. [0003] On the other hand, conventionally, there has been known a refrigeration system in which a heat source side heat exchanger is configured so that a refrigerant exchanges heat with water. For example, Patent Document 2 discloses an air conditioner configured to supply cooling water from a cooling container to a heat source side heat exchanger. [0004] Patent Document 1:...
