Abstract

A generator unit of an absorption heat pump system having a plurality of vertical tubular conduits around the reservoir zone in the lower portion of the generator unit, each conduit having a lower opening for drawing rich liquor from the reservoir portion. Heat is transferred from an external source into the vertical conduits. A method of separating rich liquor into refrigerant vapor and weak liquor including drawing rich liquor into vertical tubular conduits at a temperature at which bubbles of refrigerant vapor are forming in the rich liquor, heating the rich liquor in the vertical conduits thereby increasing the formation of refrigerant bubbles, driving the rich liquor upward in the vertical conduits with increasing speed by the vapor lift action of refrigerant bubbles and separating the fluid coming out of the vertical conduits into the refrigerant vapor and weak liquor.
