REFRIGERATION CYCLE APPARATUS

摘要

A refrigeration cycle apparatus comprising a main refrigerant circuit through which refrigerant circulates between a compressor (1), a heat-source-unit-side heat exchanger (3), a first flow rate control device (4), and a usage-side heat exchanger (5); wherein the apparatus has a first gas-liquid separator (20) and a contaminant recovery container (8) for recovering contaminants contained in the refrigerant, and a contaminant recovery refrigerant circuit that connects the first gas-liquid separator (20) and the contaminant recovery container (8) via a first flow channel opening/closing device (10) is installed in parallel with the main refrigerant circuit between the usage-side heat exchanger (5) and the intake side of the compressor (1).
