Abstract

Solar energy applications in Iran for supplying domestic hot water; space heating and cooling have been considered severely in last decade. The purpose of this research is to analysis of solar single effect lithium bromide-water absorption cooling system in a typical office building in Tehran. The solar energy is absorbed by heat pipes 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 Tehran climate and the specification of the building by means of optimized design of solar heat pipe collectors; up to 2400 m3/year Natural Gas energy saving can be reached by use of solar absorption cooling system. Achieving this purpose requires utilizing 16 collectors which everyone compromises 30 tubes with total absorber area of 45 m2 which is the optimum collector area for this plant in Tehran. According to this replacement the investment payback rate would be 13 years which would be much shorter than the payback time of a solar cooling system combined with conventional all air systems.
