Analysis of Solar Powered Air Conditioning Systems for Residential Applications

Abstract

In this paper the absorption air conditioning system has been analyzed, and the solar energy has been used as a source for heat required to operating the absorption cycle. The influence of most of the parameters which may affect the performance of absorption air conditioning system has been studied under the climatic conditions of Iraq. The main advantage of solar based air conditioning systems is the synchronization between the cooling demand and the availability of solar energy especially in hotregions like Iraq which containshuge potential of solar energy in summer season. The results obtained indicate the ability of using solar energy to reduce the electricity consumption for air conditioning applications. Fora certain space with cooling load 5 Ton (17.5 kW) for climatic conditions (solar radiation intensity 1000 W/m2 and ambient temperature 45oC) the solar collector with area 40 m2 can provide 75% of required heat to produce this cooling load demand and a collector with area53 m2 can provide 100 % of required heat to produce this cooling load demand for the seclimatic conditions.
