PROBLEM TO BE SOLVED: To obtain a cooling/heating water heater utilizing refrigeration cycle in which pressure loss of a heat exchanger for hot water supply, and lowering of efficiency or reliability due to variation in the optimal filling quantity caused by variation of hot water supply conditions are improved and controllability of air conditioning and hot water supply capacity is enhanced. SOLUTION: A heat exchanger for hot water supply is coupled with a bypass pipe 1 provided with a flow regulation valve 2 and, since the heat exchanger for hot water supply is bypassed, pressure loss is reduced and the efficiency is improved. Since the influence of a hot water supply cycle exhibiting a significant variation is reduced by regulating the quantity of bypass, a cooling/heating and hot water supplying apparatus in which the capacity can be distributed between hot water supply and air conditioning while ensuring operation of stabilized cycle is obtained. |
