The purpose of this thesis work was to investigate the performance of an automotive air-conditioning system experimentally and theoretically, with consideration of two-phase flow and oil concentration. An automotive air-conditioning test system with real size automotive air-conditioning components has been established to operate as a Clutch Cycling Orifice Tube system, which can measure the vapour quality and oil concentration. A Stream Analysis Model for an accumulator of automotive air-conditioning systems has been developed, and validated by the experimental results. A swash plate compressor of automotive air-conditioning has been investigated experimentally, and the effects of two-phase flow and oil concentration on its performance have been studied. The effects of refrigerant charge, inlet air temperature to evaporator, condenser surroundings temperature, and compressor speed on the performance of automotive A/C systems have been also investigated experimentally. A new automotive A/C system with an accumulator-capillary tube-suction line heat exchanger has been developed and investigated experimentally with comparison to a conventional system without an internal heat exchanger, and a system with a liquid line-suction line heat exchanger. The results show that the new system has better performance than the conventional system, such as higher cooling load and coefficient of performance, and better compressor working conditions.The purpose of this thesis work was to investigate the performance of an automotive air-conditioning system experimentally and theoretically, with consideration of two-phase flow and oil concentration.
