PROBLEM TO BE SOLVED: To stabilize operation in the downstream process to be supplied with gas by controlling the temperature of liquefied gas from which impurities are removed to a constant level. ;SOLUTION: A refrigeration system for gasifying/reevaporating gas comprises a refrigerating machine for liquefying chlorine gas containing impurities and removing the impurities while forming a refrigerant circulation channel, and an evaporator for heating/evaporating liquid chlorine from which impurities are removed. The refrigeration system further comprises a second heat exchanger 11 for heating the liquid chlorine from the first heat exchanger 10 through heat exchange with refrigerant, a refrigerant channel branched from a part of the refrigerant circulation channel on the delivery side of a compressor 1 and extending through the second heat exchanger 11 to a condenser 4, a three-way valve 3 for regulating the quantity of refrigerant flowing from the compressor 1 to the condenser 4 and the second heat exchanger 11, and a temperature detector 13 and a temperature regulator 14 for controlling the three-way valve 3 such that the liquid chlorine from the second heat exchanger 11 will have a preset temperature.;COPYRIGHT: (C)2000,JPO
