ABSTRACT
Automobile air conditioning by vapour compression refrigeration system increases the amount of energy consumed. A vapour absorption refrigeration system which will utilize vehicle engine waste heat either from the exhaust gases or from the cooling system thereby reducing energy consumption is being proposed. Estimation of automobile cooling load was undertaken as part of an investigation to determine the suitability of a vapour absorption refrigeration system for automobile air conditioning system. Heat balance method was used to estimate the various thermal loads, radiation loads and cooling load of a car with four passengers in Lagos, Nigeria. The value of the cooling load obtained was 2.35kW and it was estimated under the hot weather condition of the sun to give a fairly accurate result for design purpose.
