现在,用于客车空气调节装置的制冷机主要机型是活塞压缩式制冷机。这种制冷机在使用中最可靠,且比涡轮压缩式和热电式制冷机具有较好的动力指标。空气调节装置制冷设备的结构特点多半是由供电系统确定。在装有空气调节的客车内主要使用两种类型压缩制冷装置:苏联国产的кж-25型,它是由集中供电系统供给交流电,和民主德国产的MAБ-2型,它需要由单独供电系统供给直流电。装有空调设备的客车中多数装有MAБ-2型压缩式制冷机和单独供电系统,由轮对
At present, the main type of refrigerator used for passenger air conditioner is a piston compression refrigerator. This type of refrigerator is the most reliable in use and has better dynamic specifications than turbo-compression and thermoelectric refrigerators. Most of the structural features of air conditioning refrigeration equipment are determined by the power supply system. There are mainly two types of compressed air compressors used in air-conditioned passenger vehicles: the Soviet-made кж-25, which is supplied from a centralized power supply system to the AC and the German-made MAБ-2 from the independent power supply system Supply DC. Most air-conditioned buses are equipped with a MA-2 compression cooler and a separate power supply system,
