Absorption type heat pump

Abstract

The invention provides an absorption type heat pump, wherein even partial load is generated in the heating operation, temperature uprising of the warm water at the warm water pipe inlet side can be suppressed. The absorption type heat pump comprises a regenerator for separating refrigerant steam by heating dilute absorption liquid returned by the absorber; a condenser for condensing and liquefying the refrigerant delivered from the regenerator; an evaporator for evaporating refrigerant delivered from the condenser; an absorber for absorbing refrigerant steam delivered from the evaporator. A warm water inlet temperature sensor through the upstream side of the warm temperature pipe of the condenser, and the absorber is disposed behind the absorber. When the warm water inlet temperature sensor detects that the temperature is over the set temperature, flow of warm water to the warm water pipe is reduced. A warm water pump is disposed on the upstream side of the absorber, which controls the flow through a control device according to a detection signal from the warm water inlet temperature sensor.

Description

Technical field [0001] The present invention relates to an absorption heat pump, which can perform original high-efficiency operation as a heat pump even when it becomes a partial load. Background technique [0002] Conventionally, there has been known an absorption heat pump using water as a refrigerant and a lithium bromide (LiBr) solution as an absorption liquid, for example. The absorption heat pump has as its main components: a regenerator, which heats the dilute absorption liquid returned from the absorber to separate refrigerant vapor; and a condenser, which condenses the refrigerant vapor sent from the regenerator And liquefaction; the evaporator, which stores the refrigerant sent from the condenser, and spreads it from the diffuser to the heat transfer tube to evaporate; the above-mentioned absorber, which passes the concentrated absorption liquid sent from the regenerator The refrigerant vapor sent from the evaporator is dispersed and absorbed from the diffuser (for exa...

Problems solved by technology

[0007] In addition, if it is difficult to absorb refrigerant vapor in the absorber 5, the amount of heat absorbed from the heat source water as a sub heat source passing through the heat transfer tubes in the evaporator 4 decreases, and the heat of the sub heat source cannot be effectively used.
