Abstract:
A refrigeration cycle devicehaving a first refrigeration circuit for circulating a refrigerant from a compressor through a heat exchanger on a heat source equipment side, a flow rate adjuster, a heat exchanger on an application side, and an accumulator in a sequential manner to said corressor, comprising:an extraneous matter catching means for catching extraneous matters in said refrigerant provided between said heat exchanger on the heat source equipment side and said accumulator in said first refrigeration circuit;a first bypass path for bypassing a refrigeration circuit between said heat exchanger on the application side and said accumulator of said first refrigeration circuit, wherein said first bypass path includes said extraneous matter catching means;a second bypass path for bypassing a refrigeration circuit between said heat exchanger on the heat source equipment side and said flow rate adjuster in said first refrigeration circuit;a cooling means for refrigerant provided in said second bypass path; anda heating means for refrigerant provided on an upstream side of said extraneous matter catching means in said first bypass path.
