Abstract

PURPOSE: To improve defrosting characteristic and shorten the defrosting time by connecting in parallel a discharge electromagnetic valve and a discharge pressure controlling valve to the conduit which connects a compressor and a condenser.
CONSTITUTION: On the way of a pipe 2 which connects a condenser 3 with the discharge port side of a compressor 1, a discharge electromagnetic valve 4 and a discharge pressure controlling valve 5 are connected in parallel. The discharge electromagnetic valve 4 closes, in defrosting, with a main liquid electromagnetic valve 7, liquid electromagnetic valve 18, and a suction electromagnetic valve 33, and a hot-gas electromagnetic valve 42 is opened. Thus, a prescribed pressure for the discharge pressure controlling valve 5 in which coolan gas passes which has a high temperature and pressure and is discharged from the compressor 1 is set at a value sufficient to complete defrosting rapidly. Thus, the pressure of defrosting coolant gas in high temperature and pressure is maintained stably, and defrosting faculty can be improved, and the defrosting time can be shortened.
