Abstract

The invention provides an aborption heat pump capable of realizing stabilization of a liquid level of the part of a liquid storing a heated medium. The absorption heat pump (1) has an absorber (10), an evaporator (20), a regenerator (30), a condenser (40), a heated medium gas-liquid separation unit (8-) which imports a heated medium (Wm) heated in the absorber (10) and separates the heated medium into vapor (Wv) and liquid (Wq) of the heated medium, a vapor generation flow mastering unit (62) which masters generated flow of the vapor of the heated medium, a heated medium liquid supply device (86) which supplies the liquid (Ws) of the heated medium to the absorber, and a supply control unit (64) which controls the heated medium supply device (86) so that liquid (Ws) of the heated medium of the flow correspdoning to the generated flow of the vapor (Wv) of the heated medium mastered by the vapor generation flow mastering unit is supplied to the absorber (10).

Description

technical field [0001] The present invention relates to an absorption heat pump, and more particularly, to an absorption heat pump capable of stabilizing the liquid level of a portion storing liquid in a medium to be heated. Background technique [0002] Among the heat pumps that extract heat from a low-temperature heat source to heat a medium to be heated, absorption heat pumps are known as heat-driven heat pumps. Absorption heat pumps include heat-increasing heat pumps that obtain more heat than the heat input as a heat source, that is, the first type of absorption heat pump, and temperature-increasing heat pumps that obtain a heated medium that is at a temperature higher than that of the driving heat source, that is, the second type of absorption heat pump. An absorption heat pump mainly includes an evaporator for evaporating a refrigerant liquid, an absorber for absorbing refrigerant vapor through an absorption liquid, a regenerator for detaching the refrigerant from the...
