Title:
REFRIGERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/105511
Kind Code:
A1
Abstract:
An intermediate pressure heat exchanger (40) and a supercooling heat exchanger
(60) are installed in a refrigerant circuit (20). In the refrigerant circuit
(20), a first flow passage (61) of the supercooling heat exchanger (60) is disposed
on the downstream side, relative to the direction of refrigerant circulation
in cooling operation, of the first flow passage (41) of the intermediate pressure
heat exchanger (40). In the cooling operation, a high-pressure liquid refrigerant
is cooled while it passes through the first flow passage (41) of the intermediate
pressure heat exchanger (40) and is supplied to an indoor circuit (70) after it
is further cooled while passing through the first flow passage (61) of the supercooling
heat exchanger (60).
