PROBLEM TO BE SOLVED: To adjust and suppress pressure loss and heat load due to a dew-proofing pipe according to an installation environment or operation state of a refrigerator by optionally selecting one among a plurality of dew-proofing pipes in parallel connection to the downstream side of a main condenser via a flow path switching valve.SOLUTION: The parallel and simultaneous use of a plurality of dew-proofing pipes during overload in which a circulation amount of refrigerant is large can suppress pressure loss due to a dew-proofing pipe, and the reduction of the number of dew-proofing pipes during normal load in which a circulation amount of refrigerant is small can suppress heat load due to a dew-proofing pipe. |
