Abstract:
1. A water circulation system associated with a refrigerant cycle comprising: a first refrigerant circulation unit where a first refrigerant exchanging heat with outdoor air flows to perform the refrigerant cycle; a second refrigerant circulation unit where a second refrigerant exchanging heat with the first refrigerant flows to perform the refrigerant cycle; a water circulation unit where water for at least one of indoor heating/cooling and hot water supplying flows; a first water refrigerant heat exchanger that performs the heat exchange between the first refrigerant and water; a second water refrigerant heat exchanger that performs the heat exchange between the second refrigerant and water; a first flow control unit that selectively prevents the flow of water to the first water refrigerant heat exchanger; and a second flow control unit that selectively prevents the flow of water to the second water refrigerant heat exchanger.
