In this paper, a detailed energy and exergy analysis have been dealt with on experimental AAC (Automobile Air Conditioning) system with R134a as working refrigerant. For this aim, an experimental AAC system consisting of a laminated type evaporator, swash plate type compressor, a parallel flow type condenser, TXV(thermostatic expansion valve) and a receiver drier. The performance analysis of separate components of AAC system has been carried out under various compressor speeds and thermal loads. AAC system equipped with increasing compressor speed by three-phase electric motor controlled by frequency converter. Various thermal loads in the range of 1500 and 2850 W were applied to the system by means of electric heaters. The experiments were conducted at the condensing temperatures of 50-60 oC for each thermal load, and at the compressor speeds of 600, 800, 1000, 1200, 1400 rpm for each thermal load-condensing temperature combination. The refrigerant and air temperatures, refrigerant pressures, compressor speed, air velocity passing through the evaporator and thermal load were measured. Effects on system performance of such operational parameters as compressor speed, return air in the evaporator and condensing air temperatures have been experimentally evaluated and by means of energy and exergy analysis.

Energy and exergy analysis of the air conditioning systems employing the mixture of outdoor and return air (ACOR) are presented. The equations of heat transfer rate and exergy destruction are developed for ACOR according to the system parameters of moist air and condensate water. The effects of the incoming air dry bulb temperature to the coil and relative humidity, and leaving air dry bulb temperature from the coil on the heat transfer and exergy destruction are investigated by means of a computer code developed. The heat transfer from the air to the coil increased as the incoming air dry bulb temperature and relative humidity increased while the heat transfer decreased with the increase in the leaving air dry bulb temperature. The exergy destruction of the moist air increased as the incoming air dry bulb temperature increased, but it decreased with the increasing values of incoming air relative humidity values.
