ABSORPTION HEAT PUMP

PROBLEM TO BE SOLVED: To provide an absorption heat pump for suppressing temperature rise of hot water at a hot water pipe inlet side even when partial load is generated during a heating operation. SOLUTION: This absorption heat pump includes a regenerator 1 for heating diluted absorbing liquid returned from an absorber 5 and separating refrigerant vapor, a condenser 2 for condensing and liquefying the refrigerant vapor distributed from the regenerator 1, an evaporator 4 for evaporating a refrigerant liquid distributed from the condenser 2, and the absorber 5 for absorbing the refrigerant vapor distributed from the evaporator 4, a hot water inlet temperature sensor 13 is disposed at an upstream side with respect to the absorber 5, of a hot water pipe 11 passing through the condenser 2 after passing through the absorber 5, and a hot water flow rate to the hot water pipe 11 is reduced when the hot water inlet temperature sensor 13 detects a prescribed temperature or more. A hot water pump 12 is disposed at an upstream side with respect to the absorber 5, and flow rate control is performed by the hot water pump 12 through a control device 15 on the basis of a detection signal from the hot water inlet temperature sensor 13.
