Abstract:
In recent years, Air conditioning appliances in buildings are responsible for a large percentage of the ozone depletion and greenhouse effect . The purpose of this research is to analysis of solar single effect lithium bromide-water absorption cooling system in a typical office building in Kerman. The solar energy is absorbed by heat pipe solar collectors and stored in an insulated storage tank. This system has been designed to supply the cooling load of mentioned typical office building where the cooling load is 35.17KW ( 10 tons of refrigerant) which events in July. Results demonstrate that depending on the Kerman climate and the specification of the building by means of optimized design of solar heat pipe collectors, up to 2500 m3/year Natural Gas energy saving can be reached by use of solar absorption cooling system. Achieving this purpose requires utilizing 13 collectors which everyone compromises 30 tubes with total absorber area of 41 m2 which is the optimum collector area for this plant in Kerman. According to this replacement the annual reduction of CO2 is equal or greater than 5 Kg and the investment payback rate would be 11.4 years which would be much shorter than the payback time of a solar cooling system combined with conventional all air systems.
