Abstract
A refrigeration cycle device having 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 the compressor, comprising an extraneous matter catching means for catching extraneous matters in the refrigerant provided between the heat exchanger on application side and the accumulator of the first refrigeration circuit, and an oil separating means for separating a refrigerating machine oil in the refrigerant to separate the extraneous matters and the refrigerating machine oil from the refrigerant, by such a structure only a heat source equipment A and an indoor unit B can be newly exchanged without exchanging connection pipes C and D for connecting the heat source equipment and the indoor unit after flushing operation for introducing a new refrigerant.
