Abstract

An absorption heat pump apparatus using a refrigerant as a heat exchanging medium includes a vapor generator for producing a dilute refrigerant solution and a heat exchanger having an evaporator for producing evaporated refrigerant gas and an absorber for making the evaporated refrigerant gas to be absorbed into the dilute refrigerant solution. A plurality refrigerant paths extending inside the evaporator and absorber for flowing the refrigerant inside for heat exchange operation. Each inlet end of refrigerant paths is connected to an inlet before the evaporator by a plurality of first capillary paths. Each outlet end of refrigerant paths is joined to an outlet. A plurality of second capillary paths are connected to the refrigerant paths before the absorber for supplying the dilute refrigerant solution to the absorber. When passing through the capillary paths, the refrigerant is cooled due to the pressure loss.

Dependent claims

A heat pump apparatus using a refrigerant as a heat exchanging medium comprising:

refrigerant solution means for producing a poor solution of said refrigerant;
and
heat exchange means, said heat refrigerant means comprising:
evaporation means for evaporating said refrigerant to produce a refrigerant vapor thereof;
first refrigerant path means provided inside said evaporating means passing therethrough, said first refrigerant path means having an inlet for taking said refrigerant and a predetermined number of first refrigerant paths which are branched from said inlet and extending out said evaporation means for carrying said taken refrigerant and said refrigerant vapor therethrough;
absorption means for making said refrigerant vapor be absorbed into said poor solution;
and
second refrigerant path means provided inside said absorption means passing therethrough, said second refrigerant path means having said predetermined number of second refrigerant paths including first ends each connected to a branched end of said first refrigerant paths for taking said refrigerant vapor into said absorption means and second ends, and said second refrigerant paths further including an outlet joining said second ends of second refrigerant paths for carrying said refrigerant vapor absorbed poor solution therefrom.
