Conventionally, absorption type heat pumps have been used to recover waste heat, and this system is shown in Figure 1. That is, the waste heat fluid (a) is passed through the evaporator (1), where heat is removed by evaporation of the refrigerant, and the vaporized refrigerant moves to the absorber (2) and is absorbed into the absorber (2). (2) Heated fluid passing through (e.g. boiler feed water)

In addition, a part of the waste heat fluid (waste heat fluid) is guided to the regenerator (3) without passing through the evaporator (11), and is sent from the absorber (2) via the pump (4). The absorption liquid (c) is heated to evaporate the refrigerant in the dilute absorption liquid.Then, this vaporized refrigerant further enters the condenser (5) and is condensed by the cooling fluid (e.g. cooling water) (d). It's been a long time since I've been in the middle of a long time (6), (
7) to the evaporator (1). In addition, the regenerator (
The concentrated absorption liquid (e) that has been absorbed in 3) is sent to the absorber (2) by the pump (8), but on the way it passes through the heat exchanger (9).
) heat is recovered from the dilute absorption liquid (c). However, conventionally, according to such a device, only one type of waste heat fluid heating tube (heat transfer tube B) is provided in the evaporator (1) and regenerator (3), for example. When there are many types of waste heat fluids nearby and the heat is to be recovered, an absorption heat pump must be installed for each waste heat fluid, which has the disadvantage of increasing equipment costs.
