<p>To provide a refrigeration cycle where, when an internal heat exchanger is also adopted by the refrigeration cycle in addition to a condenser with a supercooling part, a rate at which the supercooling part occupies with respect to the whole condenser is set again such that an optimum sub cool can be acquired as the whole refrigeration cycle and an amount of refrigerant to be filled can be relatively reduced. In a refrigeration cycle 1 which is constituted by suitably joining at least a compressor (2), a condenser (3), a decompression and expansion device (4), and an evaporator 5 to each other by a pipe (6), the condenser 3 is formed of a condenser with a supercooling part including a condensing part (7) and a supercooling part 8, the refrigeration cycle 1 further includes an internal heat exchanger (25), and a rate at which the supercooling part 8 occupies with respect to the whole condenser (3) is set to a value which falls within a range of 3% to 9% when the heat exchange efficiency of the internal heat exchanger (25) falls within a range of 25% to 75%.</p> |
