PROBLEM TO BE SOLVED: To provide a refrigeration cycle device including a plurality of refrigeration cycle circuits and a hot water circuit, capable of improving defrosting efficiency and shortening defrosting time by using heat absorbed by one of the refrigeration cycle circuits for defrosting the other refrigeration cycle circuit via the hot water circuit.SOLUTION: A refrigeration cycle device comprises: a first refrigeration cycle circuit 1; a second refrigeration cycle circuit 2; and a hot water circuit 5 cooling a heat source 3. The first refrigeration cycle circuit 1 and the second refrigeration cycle circuit 2 are controlled so that one performs a heating operation when the other performs a defrosting operation. By so controlling, the first refrigeration cycle circuit 1 and the second refrigeration cycle circuit 2 do not perform defrosting operations simultaneously. A control unit 6 compares a temperature of hot water with a temperature of high-pressure discharge gas serving as refrigerant flowing in the first refrigeration cycle circuit 1 when the first refrigeration cycle circuit 1 starts the defrosting operation. The control unit 6 supplies the hot water of the hot water circuit 5 to a first water-refrigerant heat exchanger 13 if determining that the first refrigeration cycle circuit 1 is in a state of being able to absorb heat from the hot water as a result of comparison.SELECTED DRAWING: Figure 1
【課題】複数の冷凍サイクル回路と温水回路とを有する冷凍サイクル装置において、一方の冷凍サイクル回路で吸熱した熱を、温水回路を介して他方の冷凍サイクル回路の除霜に活用することで、除霜効率を向上させ除霜時間の短縮を図る。【解決手段】冷凍サイクル装置は、第１冷凍サイクル回路１と、第２冷凍サイクル回路２と、熱源３を冷却する温水回路５とを備える。第１冷凍サイクル回路１と第２冷凍サイクル回路２とは、一方が除霜運転の時に他方が暖房運転を行うように制御される。これにより、同時に除霜運転を行わない。制御装置６は、第１冷凍サイクル回路１が除霜運転になると、温水の温度と第１冷凍サイクル回路１を流れる冷媒の高圧吐出ガス温度とを比較する。その結果、第１冷凍サイクル回路１が温水から吸熱できる状態であると判定した場合は、第１水冷媒熱交換器１３に温水回路５の温水を流す。【選択図】図１
