REFRIGERATOR

WIPO Patent Application WO/2021/019770

A1

A refrigerator (100) comprises a refrigerant circuit which includes a compressor (1), a condenser (2), a throttle device (3), an evaporator (4), and a double pipe (11) and in which refrigerant circulates through the compressor, condenser, throttle device, evaporator, and double pipe in this order. The compressor includes a suction port for sucking in refrigerant. The double pipe has an inner pipe (21) and an outer pipe (22) that is disposed so as to enclose the inner pipe and is connected to the suction port. A first space (S1) which connects the evaporator and suction port in the refrigerant circuit is formed inside the inner pipe. A second space (S2) which is demarcated from the first space by the inner pipe and is demarcated from the space outside the double pipe by the outer pipe is formed between the inner pipe and outer pipe. An end part (211) of the inner pipe and an end part (221) of the outer pipe which are located upstream of the refrigerant circuit are hermetically sealed with each other. An end part (212) of the inner pipe and an end part (222) of the outer pipe which are located downstream of the refrigerant circuit are disposed spaced apart from each other.
