AIR CONDITIONING DEVICE

摘要

An air conditioning device comprising a refrigerant circulation circuit (A), a heat medium circulation circuit (B), and a heat medium converter control device (52) that executes foreign matter removal whereby foreign matter inside the heat medium circulation circuit (B) is captured by a strainer (42) during construction. The refrigerant circulation path (A) comprises, connected by pipes: a compressor (10) that compresses a heat source-side refrigerant; a first refrigerant flow path switching device (11) for switching the circulation path for the heat source-side refrigerant; a heat source-side heat exchanger (12) for exchanging heat source-side refrigerant heat; a throttle device (16) for adjusting the pressure of the heat source-side refrigerant; and an inter-heat-medium heat exchanger (15) that exchanges heat between the heat source-side refrigerant and a heat medium that differs from the heat source-side refrigerant. The heat medium circulation path (B) has, connected by pipes: a pump (21) for circulating the heat medium for heat exchange by the inter-heat-medium heat exchanger (15); a usage-side heat exchanger (26) that exchanges heat between the heat medium and the air to be air conditioned; flow path switching devices (22, 23) that switch between passage, to the usage-side heat exchanger (26), of a heat medium that has been heated and a heat medium that has been cooled; and the strainer (42) that captures foreign matter in the heat medium.
