ABSORPTION HEAT PUMP DEVICE AND ITS USE DEVICE

PROBLEM TO BE SOLVED: To provide a concentration device using an absorption heat pump and having excellent thermal efficiency. SOLUTION: Liquid to be concentrated such as fruit juice, salt water, and milk supplied to a concentration device 10 through a supply pipe 31 for liquid to be concentrated is heated through a heat transfer pipe 4A of an absorber 4, a heat transfer pipe 6A of a second resorber 6, a heat transfer pipe 5A of a first resorber 5, and a heat transfer pipe 2A of the concentration device 2 and is heated by hot water circulating and supplied through a hot water pipe passage 20 to evaporate water vapor. The concentrated liquid is discharged into a discharge pipe 32 for concentrated liquid, and steam generated in the concentration device 10 is supplied to a heat transfer pipe 3A of an evaporator 3, a heat transfer pipe 7A of a first desorber 7, and a heat transfer pipe 8A of a second desorber 8 as a heat source to reduce flow rate of driving heat source introduced into a heat transfer pipe 1A of the regenerator 1 through a heat source supply pipe 18.
