US 2019/0293333 A1 · REFRIGERATION CYCLE APPARATUS

Abstract

A refrigeration cycle apparatus according to the present invention performs cooling by circulation of refrigerant. The refrigeration cycle apparatus includes an evaporator, a condenser, a pump, a compressor, and a control device. The evaporator is arranged in a first space. The condenser is arranged in a second space. The pump is configured to compress refrigerant from the condenser and output the refrigerant to the evaporator. The compressor is configured to compress refrigerant from the evaporator and output the refrigerant to the condenser. The control device is configured to control the pump and the compressor to cool the first space. The control device is configured to turn on the pump after turn-on of the compressor while a temperature of the first space is higher than a temperature of the second space.
