Abstract (en)
[origin: EP2679934A1] A control device (1a) calculates an air conditioning heat radiating amount, a hot-water supply heat absorbing amount, a target condensation temperature at an air conditioning refrigerant circuit (5), and a target evaporation temperature at a hot-water supply refrigerant circuit (6) in a case where a cooling operation by an air conditioning cycle and a hot-water supply operation by a hot-water supply cycle are simultaneously executed in order to provide an air conditioning and hot-water supply system which can preferably distribute a refrigerant in a cycle having a large heat amount to a heat exchanger for recovering exhaust heat, and a heat exchanger for exhaust heat in an exhaust heat recovery operation and a control method of the air conditioning and hot-water supply system. There is provided an air conditioning and hot-water supply system in which in a case where the air conditioning heat radiating amount is larger than the hot-water heat absorbing amount, the control device (1a) closes a hot-water supply refrigerant flow rate adjusting valve (49a) arranged at a hot-water supply refrigerant inlet (44a) of a hot-water supply side heat exchanger (44) and adjusts a valve opening degree of an air conditioning refrigerant flow rate adjusting valve (35c) arranged at a cooling time air conditioning refrigerant inlet (24a) of an air conditioning heat source side heat exchanger (24) based on a temperature of a vicinity of a cooling time air conditioning refrigerant outlet (24b).
