Air conditioning demand is rapidly increasing in many parts of the world, especially in moderate climates. Air conditioners and refrigerators are the only equipment’s consumes more electricity say 70% in the household articles. This results in a dramatic increase in electricity demand on hot summer days, which causes an unwanted increase in the use of fossil fuel and nuclear energy, leads to global warming and air pollution. This paper describes the usage of vapour absorption air conditioning systems using solar thermal energy. In this system an electric generator is replaced by solar thermal collectors for heating the refrigerant called LiBr-Water. During this study an atmospheric temperature, fluid temperature at the collector and the temperature of space to be conditioned were measured to find out the COP of the system. The specifications of the entire system components are arrived based on the design calculations recommended by ASHRAE. The experimental results shows that there is a drastic decrease in the dry bulb temperature when compared with outside dry bulb temperature. The main objective of this study is to reduce the electricity consumption by introducing solar thermal energy.
