Title:
REFRIGERATION CYCLE DEVICE FOR AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2022/210937
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device for an automobile, which can effectively use different temperature regions of a heat exchanger created by using a zeotropic refrigerant mixture. The present invention is provided with a refrigerant circuit (10) which has an indoor heat exchanger (18) including a first indoor heat exchanger (16) and a second indoor heat exchanger (17), and in which a zeotropic refrigerant mixture circulates. The first indoor heat exchanger (16) and the second indoor heat exchanger (17) are arranged in series with each other in the flow of refrigerant in the refrigerant circuit (10). In the refrigerant flow direction when the first indoor heat exchanger (16) and the second indoor heat exchanger (17) are caused to function as refrigerant evaporators, the first indoor heat exchanger (16) is positioned upstream of the second indoor heat exchanger (17).
