ABSTRACT:
An absorption cooling and heating apparatus and method, in which generator means evaporates a refrigerant from a solution therewithin to form refrigerant vapor, and condenser means then condenses the refrigerant vapor so produced within the generator means. Evaporator means receives the condensed refrigerant from the condenser means, and evaporates the same to form vapor therewithin, with absorber means being provided to absorb the refrigerant vapor that was formed in the evaporator means. The absorber means also receives a concentrated solution conveyed from the generator means, and delivers a dilute solution to the generator means. Heat exchanger means is provided for effecting heat exchange between the concentrated solution being passed to the absorber means, and the dilute solution being returned back to the generator means. Also, switch means for alternately changing to a cooling or to a heating cycle is provided. The condensed refrigerant passed from the condenser means is mixed with the dilute solution being passed back into the generator means, by compulsory mixing means such as an ejector or a refrigerant pump, with the aid of the switching means. The generator means may also comprise a separate high temperature generator and a low temperature generator, with refrigerant vapor being condensed through a condensation conduit passing through the low temperature generator to thereby heat the solution therewithin, and then being mixed with the dilute solution being supplied to the low temperature generator itself, by virtue of the inner pressure generated within the high temperature generator.
