Abstract:
An absorption heat pump system, comprising a generator means, a heating means, a condenser means, an pressure reducing means, an evaporator means, an absorber means, a pumping means, said elements so arranged and so fluid flow connected by tubes and connections, that a refrigerant rich solution is pumped into said generator means and heated by said heating means whereby refrigerant vapor is evolved, after which the refrigerant vapor is conducted into said condenser means wherein said refrigerant in condensed and from whence liquid refrigerant flows through said pressure reduction means and evaporates within said evaporator means after which the refrigerant vapor flows into said absorber wherein the vapor is absorbed into refrigerant depicted solution which is thereby enriched prior to being pumped by said pumping means into said generator wherein refrigerant each solution is heated and deprived of a portion of refrigerant and, as refrigerant poor solution, is returned to said absorber as in conventional absorption heat pump systems, the improvement comprising said generator being in the form of a vortex chamber, said vortex chamber generator comprising a tangential inlet, a central outlet and a tangential outlet, said elements are no arranged that refrigerant rich solution enters said vortex chamber through said tangential inlet and is accelerated at constant rotational momentum with a concomitant pressure reduction below the vapor pressure of the refrigerant fraction of said refrigerant rich solution, said refrigerant traction being the most volatile portion of said solution, such that a portion of said refrigerant evolves from said refrigerant rich solution in the form of refrigerant vapor which, being lighter, floats upward and out of said vortex chamber through said central outlet and toward said condensation means as in conventional systems while refrigerant depicted solution flows out of tangential outlet toward said absorption means whereby the generation of refrigerant vapor in an absorption heat pump system occurs at a lower temperature as desired.
