TUBE FOR RADIATOR OR EVAPORATOR

摘要

PROBLEM TO BE SOLVED: To provide a tube for a radiator or an evaporator appropriate for a supercritical freezing cycle. SOLUTION: An equivalent diameter D of a tube for a radiator is set to 0.25-0.8 mm, and the equivalent diameter de of a tube for an evaporator is set to 0.46-0.72 mm. Thus the heat exchange capacity can be maintained high, and a tube for a radiator and evaporator appropriate to a supercritical freezing cycle can be obtained.
