ABSORPTION HEAT PUMP

Japanese Patent JP2016061519

A

PROBLEM TO BE SOLVED: To provide an absorption heat pump capable of restricting the reduction in efficiency of heat transfer to the heated medium.SOLUTION: An absorption heat pump comprises an absorber 10 for heating a heated medium w circulating through a heat exchanger tube 12 with the heat of absorption produced when an absorbent Sa absorbs refrigerant vapor Ve so as to evaporate the heated medium w in the heat exchanger tube 12, in which the heat exchanger tube 12 includes: a preheating tube 12p for heating up heated medium liquid Wq; and a generation tube 12e for evaporating the heated medium liquid Wq heated up in the preheating tube 12p. The absorber 10 is configured by connecting one end of each generation tube 12e to a generation pipe distribution part 14es and by connecting the other end of each generation tube 12e to a generation pipe collection part 14ec; the generation pipe distribution part 14es and the generation pipe collection part 14ec are respectively composed of one part; and the heated medium w flowing through each interior of a plurality of generation tubes 12e is configured not to merge during flowing from the generation pipe distribution part 14es to the generation pipe collection part 14ec.SELECTED DRAWING: Figure 3
