REFRIGERATION CYCLE DEVICE

Title:

REFRIGERATION CYCLE DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/070614

Kind Code:

A1

Abstract:

A refrigeration cycle device is provided that comprises heat radiation parts (12, 40, 42, 27) that cause a refrigerant discharged from a compressor (11) to radiate heat into air that is to be blown into an air-conditioned space, and a heating part (43) for heating a human body in a space that is to be air-conditioned or the air by using a heat source different from the refrigerant. A feature of the refrigeration cycle device is that a first change rate, which is a change rate of heat radiation capability in the heat radiation parts relative to the energy consumption of the compressor per unit time, exceeds a second change rate, which is a change rate of heating capability in the heating part relative to the energy consumption of the heating part per unit time, when the energy consumption of the compressor per unit time falls below an upper limit (Pe_limit), whereas the first change rate falls below the second change rate when the energy consumption of the compressor per unit time exceeds the upper limit. A control unit (60) controls the compressor such that the energy consumption of the compressor per unit time is not higher than an optimum value.
