Abstract
A simplified, low cost absorption heat pump includes a single pressure vessel having first and second insulated compartments in unrestricted fluid communication with one another and containing, hermetically sealed, a working medium. A heat transfer ar is used to maintain the compartments at differential temperatures, but equal pressures so that the absorption cycle proceeds in a two-stage, batch mode, namely boiling of the working medium in the first compartment and simultaneous condensing in the second compartment during the first stage and evaporating in the second compartment and simultaneous absorbing in the first compartment during the second stage. The heat transfer arrangement then utilizes the heat given off or taken in during the absorption cycle for heating/air conditioning in a conventional manner. Periodically the working medium is rectified by a unique pump arrangement which transfers any working medium in the second compartment back to the first compartment after a predetermined number of cycles have been completed.
