Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/092464
Kind Code:
A1
Abstract:
This refrigeration cycle device is provided with switching units (38, 39) which switch between: a state in which a heat medium in a first heat medium refrigerant heat exchanger and a heat medium in a second heat medium refrigerant heat exchanger circulate independently of each other; and a state in which the heat media circulate between the first heat medium refrigerant heat exchanger and the second heat medium refrigerant heat exchanger. In this refrigeration cycle device, a control device (40) switches between: a first mode in which a first pressure reduction unit and a second pressure reduction unit operate so that a refrigerant absorbs heat in an outside air refrigerant heat exchanger and in which the switching unit operates so that the heat medium in the first heat medium refrigerant heat exchanger and the heat medium in the second heat medium refrigerant heat exchanger circulate independently of each other; and a second mode in which the first pressure reduction unit and the second pressure reduction unit operate so that the refrigerant radiates heat in the outside air refrigerant heat exchanger and in which the switching unit operates so that the heat medium circulates between the first heat medium refrigerant heat exchanger and the second heat medium refrigerant heat exchanger.
