HIGH EFFICIENCY AND LOW COST LIBR ABSORPTION MACHINE FOR SOLAR AIR-CONDITIONING
Global energy shortage and environmental deterioration have stimulated solar-energy application. Economic benefit is still the main concern for application of solar driven air-conditioning. A new scheme of utilization of solar energy is presented, which focuses domestic building as the object, arranges solar collector arrays on the roof of the building, supplise hot water for whole community in the building year-round and supplies air-conditioning chilling in summer and heating in winter for rooms in top one or two stairs with a LiBr absorption machine. A combined double-effect and single-effect LiBr absorption cycle is proposed, which enables the machine operate within double-effect cycle in meanwhile accumulate heat in a hot water tank during irradiation daytime and within single-effect one, the heat supplied by the accumulated hot water tank in the remaining time. Because the required heating temperature for the two cycles is far different, the density of energy storage is very high. Finally, a scheme of LiBr absorption machine consisted in plate-shell heat exchangers is presented, which is a suitable type of small-size machine for solar air-conditioning.
