Application of air conditioning is widespread in the United States; any new system for heating buildings must be at least compatible with it to be commercially viable. A wide variety of options exists to provide air conditioning along with solar heating for buildings. The effectiveness and efficiency of coupling these air conditioning options with solar heating depends strongly on which solar heating system is being contemplated. This paper discusses the relative merits and the state of development of several solar boosted heat pump systems with regard to their ability to provide air conditioning using conventional vapour compression refrigeration cycles. A brief description is given of the status of solar fired air conditioning. Clues to an approach to cool storage in solar air conditioning systems are given by an assessment of cool storage for reducing peak electrical loads from conventional air conditioning equipment. A system using hydrated salts in a rolling cylinder thermal energy storage device for compact and effective cool storage is described. References are given to provide the interested reader with more detailed information.
