Abstract

PROBLEM TO BE SOLVED: To obtain a required refrigerating capacity and permit contribution to energy saving by a method wherein refrigerant, whose heat is exchanged in a first cooler, is conducted to flow into a second cooler while the refrigerant, whose heat is exchanged in the second cooler, is conducted to flow into the first cooler and is returned into a compressor. SOLUTION: A first evaporator 8 is connected to a condenser 19 through a suction heat exchange pipe 20 and is connected to a compressor 18 through a discharging heat exchange pipe 21. A second evaporator 9 is connected to the suction heat exchange pipe 20 as well as the discharging heat exchange pipe 21 through a second heat exchange pipe 23 while the discharging heat exchange pipe 21 of the first evaporator 8 is connected to the compressor 18 through a suction pipe 25. Gas refrigerant, compressed by the compressor 18, is cooled in a condenser 19 and, thereafter, is evacuated through expansion in a capillary tube 26 and is conducted to flow into the suction heat exchange pipe 20 of the first evaporator 8. Subsequently, the gas refrigerant is conducted to flow into the second heat exchange pipe 23 of the second evaporator 9 and, thereafter, is sucked into the compressor 18 through the discharging heat exchange pipe 21 of the first evaporator 8.
