Abstract
According to one embodiment, this outdoor unit of an air conditioner includes a compressor, a heat exchanger, an expansion valve, a blower fan, electrical components, and a heat sink. The heat exchanger includes a first group constituted of at least one of the plurality of heat exchangers and a second group constituted of at least one of the plurality of heat exchangers not belonging to the first group. The expansion valve includes a first expansion valve and a second expansion valve. The heat sink is arranged on the flow path of the refrigerant on the upstream side of a confluence position of the refrigerant branches condensed by the heat exchangers of the first group and the second group and on the downstream side of the second expansion valve.
Claims6
An outdoor unit of an air conditioner comprising:
- a compressor which discharges a refrigerant into a flow path;
- a four-way valve;
- a heat exchanger;
- an expansion valve;
- a blower fan;
- electrical components which control the compressor and the blower fan;
- and a heat sink which cools the electrical components by the refrigerant, wherein
- the heat exchanger is formed in such a manner that a plurality of heat exchangers are connected in parallel with each other, and includes a heat exchanger of a first group constituted of at least one of the plurality of heat exchangers and a heat exchanger of a second group constituted of at least one of the plurality of heat exchangers not belonging to the first group,
- the expansion valve includes a first expansion valve which adjusts a degree of supercooling of the heat exchanger of the first group and a second expansion valve which adjusts a degree of supercooling of the heat exchanger of the second group, and
- when the second group of heat exchangers functions as a condenser, the heat sink is arranged on the flow path of the refrigerant on the upstream side of a confluence position of the refrigerant condensed by the heat exchangers of the first group and the second group and on the downstream side of the second expansion valve,
- when the second group of heat exchangers functions as an evaporator, the heat sink is arranged on the flow path of the refrigerant on the downstream side of the confluence position and on the upstream side of the second expansion valve.
