Abstract

To provide a refrigeration cycle apparatus capable of effectively reusing existing pipes, the refrigeration cycle apparatus is formed by connecting a compressor (1), a heat source unit side heat exchanger (3), an expansion device (4, 9a, 9b) and a using side heat exchanger (10a, 10h) by means of a liquid refrigerant pipe (7) and a gas refrigerant pipe (12). The gas refrigerant pipe (12) is provided with a strainer (14), and the liquid refrigerant pipe (7) is provided with a receiver (5) in which an opening of each of pipes (51, 52) on an upstream side and a downstream side of the liquid refrigerant is provided, and in which a filter device which defines a space (62) at each of the openings, and has two filters (53, 54) for capturing different target objects, respectively, discharged from the refrigerant pipe is provided.
