摘要汽车的出厂检验包括汽车空调的运转合格检验，在这个检验过程中，由于生产节拍的控制，时间只有几分钟，因此高效的判断汽车空调合格与选取的检验参数密切相关。通过设计一套与环境温度湿度相关的空调出风温度湿度相对应检验装置时保证汽车空调出厂合格的重要手段。汽车出厂检验的装置主要是压缩机性能试验台，除此之外还有汽车空调器试验台，蒸发器冷凝器两器试验台等多种，而空调器的核心部件是制冷压缩机，其中所以制冷压缩机的性能最能真实反映汽车空调系统的制冷效果，所以，制冷压缩机的性能测试是汽车空调检验装置最有效也是最真实的试验方式。

Title Performance Evaluation of Integrated Automotive Air Conditioning and Heat Pump System
Abstract
This study deals with the performance characteristics of an R134a automotive air conditioning system capable of operating as an air-to-air heat pump using ambient air as a heat source. For this aim, an experimental analysis has been performed on a plant made up of original components from an automobile air conditioning system and some extra equipment employed to operate the system in the reverse direction. The system has been tested in the air conditioning and heat pump modes by varying the compressor speed and air temperatures at the inlets of the indoor and outdoor coils. Evaluation of the data gathered in steady state test runs has shown the effects of the operating conditions on the capacity, coefficient of performance, compressor discharge temperature and the rate of exergy destroyed by each component of the system for both operation modes. It has been observed that the heat pump operation provides adequate heating only in mild weather conditions, and the heating capacity drops sharply with decreasing outdoor temperature. It is also possible to improve the heating mode performance of the system by redesigning the indoor coil, using another refrigerant with a higher heat rejection rate in the condenser and employing a better heat source such as the engine coolant or exhaust gases.
