Original Study


The main objective of the proposed project is to design an air-conditioning system for a hybrid-powered car under various conditions surrounding the car during operation or when it is stationary. Hybrid energy here combines two types of energy, one is kinetic energy generated from exhaust gas recycling, and the other is solar energy generated from the photovoltaic system. Both types of hybrid energy can be converted into electrical energy sufficient to operate the electric compressor of the refrigeration system. When the car is running, the kinetic energy of the waste exhaust gases generated by the combustion of diesel fuel inside the engine is converted into electrical energy by passing it to a turbine connected to the dynamo. On the other hand, when the car is in stop mode, solar energy is invested to operate the cooling system by connecting photovoltaic cells to the battery, where it is stored and converted into electrical energy to operate the compressor. As a result, the hybrid cooling system significantly reduces engine load and fuel consumption, thus increasing engine efficiency.The results of the current study showed that it is possible to operate the air conditioning system in the vehicle during operation and when the engine is off. The study also showed an improvement in the efficiency of the engine as a result of removing the load placed on the engine as well as the coefficient of performance for the proposed cooling system increased by about 5.18% when compared to the conventional cooling system. These findings led to the discovery of a solution to the energy waste problems of the air conditioning system in a vehicle that operates in the vapor compression cycle.
