Abstract

PURPOSE: To prevent lubrication badness due to oil forming by introducing coolant R22 or R502 into a condensing unit and introducing coolant R12 into a cooling unit and closing both coolant circuits by means of valves.
CONSTITUTION: Into the coolant circuit Ci of a condensing unit 12 consisting of a compressor 1 and a condenser 2, coolant R22 or R502 is introduced, and valves CiV3, 3 are installed on both ends of said coolant circuit Ci, and the coolant is sealed. Into the coolant circuit of a cooling unit 45 consisting of an evaporator 4 and an expansion valve 5, coolant R12 is sealed, and on both ends of said coolant circuit, valves C2V6, 6 are installed, and the coolant is sealed. Valves CiV3 and CiV6 are allowed to communicate by means of a communicating pipe 7, and a refrigerating circuit 8 is formed, when valves 3 and 6 are used. Thus, lubrication badness due to oil forming is dissolved, and the return of refrigerator oil can be improved.
