In order to provide an air conditioning/hot water supply system and a control method for the air conditioning/hot water supply system which are capable of suitably distributing a coolant during a cycle with a large calorific value to a heat exchanger for exhaust heat recovery and a heat exchanger for exhaust heat, during the exhaust heat recovery operation, a control device (1a) calculates the amount of heat discharged for air conditioning, the amount of heat absorbed for hot water supply, the target condensation temperature in an air conditioning coolant circuit (5), and the target vapor temperature in a hot water supply coolant circuit (6), when the air conditioning operation in an air conditioning cycle and the hot water supply operation in a hot water supply cycle are executed at the same time. In the air conditioning/hot water supply system, the control device (1a) closes a hot water supply coolant flow rate adjustment valve (49a) arranged in a hot water supply coolant inlet (44a) in a hot water supply heat source-side heat exchanger (44) and also adjusts the opening amount for an air conditioning coolant flow rate adjustment valve (35c), arranged in an air conditioning-for-cooling coolant inlet (24a) in an air conditioning heat source-side heat exchanger (24), on the basis of the temperature in the vicinity of an air conditioning-for-cooling coolant outlet (24b), when the amount of heat discharged for air conditioning is greater than the amount of heat absorbed for hot water supply. |
