ABSORPTION TYPE HEAT PUMP EQUIPMENT

PURPOSE: To simplify construction of a passage system and an apparatus by a method wherein the heat of water vapor separated in a high-temperature regenerator is utilized as a driving heat source of a medium-temperature part regenerator of a low- temperature-side heat pump and the heat of water vapor generated herein is utilized as the driving heat source in a high-temperature part evaporator and a low-temperature part regenerator. CONSTITUTION: Absorption type heat pump equipment of a triple effect type has a low-temperature part heat pump 2 using a water solution of lithium bromide as an absorbent and a high-temperature part heat pump 3 using a water solution of nitric acid as the absorbent. The low-temperature part heat pump 2 is equipped with first and second medium-temperature part regenerators 21 and 22 heating the absorbent from a low-temperature part absorber 12 and first and second medium-temperature part condensers 23 and 24 condensing water vapor separated in the second medium- temperature part regenerator 22. As a driving heat source of the second medium- temperature part regenerator 22, the heat of water vapor from a high-temperature part regenerator 33 is used, while the heat of the water vapor separated in the second medium-temperature part regenerator 22 is made the driving heat source of a high- temperature part evaporator 31 and a low-temperature part regenerator 13.
