Document Type and Number:
WIPO Patent Application WO/2012/053157
Kind Code:
A1
Abstract:
[Problem] To provide a refrigeration cycle, wherein when an internal heat exchanger is used in addition to a condenser with a supercooling unit, the proportion of the supercooling unit in the whole condenser is set again so that optimum subcooling for the whole refrigerant cycle can be obtained and the fill volume of a refrigerant can be relatively reduced.
[Solution] A refrigeration cycle (1) configured by appropriately joining, by a pipeline (6), at least a compressor (2), a condenser (3), a reduce-pressure expansion device (4), and an evaporator (5), wherein the condenser (3) is a condenser with a supercooling unit and comprises a condensation unit (7) and the supercooling unit (8), the refrigeration cycle being further provided with an internal heat exchanger (25), and the proportion of the supercooling unit (8) in the whole condenser (3) is between 3% and 9% when the heat exchange efficiency of the internal heat exchanger (25) is between 25% and 75%.
