Solar heating and cooling system

Patent ·
OSTI ID:5696430
A system is disclosed to accomplish both air cooling and air heating of indoor space by utilizing solar energy. In principle the disclosed system is an absorption refrigeration system, wherein a solution of an evaporable refrigerant in a less evaporable solvent is passed through a solar collector-generator, but the system has additional fluid passages with the provision of changeover valves arranged so as to pass the refrigerant in heated and vaporized state from the collector-generator to an indoor heat exchanger, bypassing the condenser of the refrigerator, thereby to accomplish air heating and return the refrigerant in liquid state from the heat exchanger to the collector-generator, bypassing the absorber of the refrigerator.
