Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/044168
Kind Code:
A1
Abstract:
A refrigeration device (1) comprises: a first cascade heat exchanger (41) that conducts heat exchange between a low temperature-side refrigerant, which circulates through a low temperature-side refrigeration cycle circuit (5), and a high temperature-side first refrigerant, which circulates through a high temperature-side first refrigeration cycle unit (3a); and a second cascade heat exchanger (43) that conducts heat exchange between the low temperature-side refrigerant, which circulates through the low temperature-side refrigeration cycle circuit (5), and a high temperature-side second refrigerant, which circulates through a high temperature-side second refrigeration cycle unit (3b). The first cascade heat exchanger (41) and the second cascade heat exchanger (43) are disposed so as to be adjacent to each other in a state where the low temperature-side refrigerant flowing through the first cascade heat exchanger (41) and the low temperature-side refrigerant flowing through the second cascade heat exchanger (43) are flowing in series.
