ABSTRACT:
A combined air-heating and refrigeration system wherein the air temperature of a living area is maintained within a predetermined range. A conventional furnace isprovided with a heat exchanger for heating air carried within ducts which communicate air from within the living space for circulation past the furnace for heating. The refrigeration portion of the system may be either of the compression or of the absorption type. In the preferred embodiment an absorption type is used and comprises a generator for heating an absorbent and a refrigerant. The heated refrigerant is communicated to a condenser to cause the refrigerant to condense, and the condensed refrigerant is then expanded by a suitable expansion valve and communicated to an evaporator wherein the refrigeration process takes place. The refrigerant is then mixed with the absorber and recirculated to the generator by means of a circulation pump. Heat exchangers are provided for utilizing the heat generated by the furnace for heating the absorbent and refrigerant within the generator of the refrigeration system while the heat generated by the condenser during the condensation of the refrigerant is utilized to preheat the air being delivered from the living space for heating by the furnace.
