Analysis of Solar Powered Air Conditioning Systems for Residential Applications

Abstract

In this paper the absorption air conditioning system has been analyzed, and the solarenergy has been used as a source for heat required to operating the absorption cycle. Theinfluence of most of the parameters which mayaffect the performance of absorption airconditioning system has been studied under the climatic conditions of Iraq. The mainadvantage of solar based air conditioning systems is the synchronization between the coolingdemand 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 ofusing 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 radiationintensity 1000 W/m2and ambient temperature 45oC) the solar collector with area 40 m2canprovide 75% of required heat to produce this cooling load demand and a collector with area53 m2can provide 100 % of required heat to produce this cooling load demand for theseclimatic conditions.
