Abstract
An absorption-type heat pump includes an evaporator 1, an absorber 7, a regenerator 12, and a condenser 17. In the evaporator 1, water 4 as a refrigerant is flash-evaporated through a flash evaporating device 2. The water vapor 6 from the evaporator 1 is absorbed into an absorbent consisting of an aqueous lithium bromide solution in the absorber 7, so that a heat carrier fluid 8 is heated by the heat of absorption evolved within the absorber. In the regenerator 12, the diluted absorbent 9 received from the absorber 7 is heated with a heating fluid 13, whereby the absorbed water content of the absorbent 9 is evaporated. The concentrated absorbent 14 resulting from the step of regeneration is returned to the absorber 7, while the water vapor 16 evolved in the regenerator 12 is introduced into the condenser 17. The heat carrier fluid 8, which has been heated in the absorber 7, is passed through the condenser 17, being further heated by the heat of condensation within the condenser 17.
