A Proposed Model for Utilizing Exhaust Heat to run Automobile Air-conditioner

In these paper three fluid vapor absorption systems is used for air conditioning of four strokes, four cylinders passenger car. The capacity of air conditioner is one ton. The exhaust of car is used to heat the ammonia solution in the generator. The temperature of exhaust heat is measured at different engine speed under 1/4th and half opening of throttle valve. The analysis shows that the maximum amount of useful heat available in the exhaust gas is about 6 KJ/sec. In this study it is found that the amount of heat required for generator is 3.02 KJ/sec. However the heat present in the exhaust is more than this amount. Therefore, the required heat to run the one-ton air conditioner that is needed to convert ammonia solution into ammonia vapor is sufficient.
