n 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 hot regions like Iraq which contains
huge 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. For
a certain space with cooling load 5 Ton (17.5 kW) for climatic conditions (solar radiation
intensity 1000 W/m
and ambient temperature 45
C) the solar collector with area 40 m
provide 75% of required heat to produce this cooling load demand and a collector with area
53 m
can provide 100 % of required heat to produce this cooling load demand for these
climatic conditions
