REFRIGERATION CYCLE DEVICE

WIPO Patent Application WO/2019/031221

A1

This refrigeration cycle device is to be applied to air conditioning devices. The refrigeration cycle device is provided with a compressor (11), first heating units (12, 22, 12a), and second heating units (14, 14a, 42). The compressor compresses and discharges a refrigerant. Using the refrigerant discharged from the compressor as a heat source, the first heating units heat blowing air to be blown to a space that is to be air-conditioned. Using the refrigerant flowed out from the first heating units as a heat source, the second heating units heat the blowing air. The second heating units are disposed so as to heat the blowing air and flow the blowing air to the first heating unit side. In heating mode in which the blowing air is to be heated, the blowing air is heated by means of both the first heating units and the second heating units. Consequently, the present invention makes it possible to provide a refrigeration cycle device capable of suppressing, with a simple configuration, deterioration of heating performance of heating units even if operation mode is switched.
