Abstract
A refrigeration cycle device includes a compressor, a condenser, a first decompressor, an outside heat exchanger, and an evaporator. A predetermined part of a refrigerant passage from the condenser to the first decompressor through which the refrigerant flows is a condenser outlet portion. A predetermined part of a refrigerant passage from the first decompressor to the outside heat exchanger through which the refrigerant flows is an outside heat exchanger inlet portion. A predetermined part of a refrigerant passage from the outside heat exchanger to the second decompressor through which the refrigerant flows is an outside heat exchanger outlet portion. A volume capacity of the condenser outlet portion is larger than a volume capacity of the outside heat exchanger inlet portion. According to the refrigeration cycle device, preferable coefficient of performance of cycle can be achieved in different operation modes.
