Refrigeration cycle apparatus

A refrigeration cycle apparatus comprising:

• a refrigerant circuit configured to circulate refrigerant;
• and
• a controller configured to control the refrigerant circuit, wherein
• the refrigerant circuit comprises a compressor, a first heat exchanger, a first expansion device, a second expansion device, a third expansion device, a second heat exchanger, and a cooler configured to cool a substrate of the controller,
• in a first path of the refrigerant circuit, the compressor, the first heat exchanger, the first expansion device, the second expansion device, and the second heat exchanger are connected in order of the compressor, the first heat exchanger, the first expansion device, the second expansion device, and the second heat exchanger,
• in a second path of the refrigerant circuit, the cooler and the third expansion device are connected in order of the cooler and the third expansion device from a first point between the first expansion device and the second expansion device to a second point between the compressor and the second heat exchanger, and
• the controller is configured to control at least one of the first expansion device and the second expansion device such that a temperature of the refrigerant flowing between the first point and the cooler is higher than a dew point temperature and is equal to or lower than an outdoor air temperature.
