Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/054111
Kind Code:
A1
Abstract:
The present invention is characterized by being equipped with: a high-temperature-side refrigerant circuit (A), which circulates a refrigerant and is formed by sequentially connecting by pipes a high-temperature-side compressor (1), a high-temperature-side condenser (2), a high-temperature-side expansion valve (3), and a high-temperature-side evaporator (4); a low-temperature-side refrigerant circuit (B), which circulates a refrigerant and is formed by sequentially connecting by pipes a low-temperature-side compressor (7), an intercooler (8), a low-temperature-side condenser (9), a low-temperature-side expansion valve (16), and a low-temperature-side evaporator (17); a cascade condenser (13), which is formed by the high-temperature-side evaporator (4) and the low-temperature-side condenser (9), and which exchanges heat between the refrigerant flowing in the high-temperature-side evaporator (4) and the low-temperature-side condenser (9); and a blower that supplies air to the high-temperature-side condenser (2) and the intercooler (8). In addition, the intercooler (8) and at least a portion of the high-temperature-side condenser (2) are formed by means of an integrated heat exchanger in which a heat transfer fan (42) is integrated.
