最近二十年来,世界各国汽车空调装置发展迅速。近些年来,各国以节能为重要课题,又研制了不少新型结构的空调压缩机。除大客车上的独立式冷气机组外,一般汽车空调压缩机是靠风扇皮带由发动机直接驱动。的,因而压缩机的转速与发动机的转速变化成比例。若以怠速时转速为1计,高速时转速可增加到10,这样大的转速变化对制冷工况影响极大,往往与车厢内的舒适性要求有矛盾。汽车空调压缩机的使用条件与一般制冷压缩机不同,在性能结构上有下列特殊要求。
In the recent two decades, the automobile air conditioners in various countries in the world have been developing rapidly. In recent years, various countries regard energy conservation as an important issue and have developed many new-type air-conditioner compressors. In addition to independent air-conditioning units on the bus, the general automotive air conditioning compressor is driven directly by the engine by the fan belt. Therefore, the speed of the compressor is proportional to the speed of the engine. If the idling speed of 1 count, the speed can be increased to 10 high speed, such a large speed change on the cooling conditions greatly affected, often with the comfort requirements within the compartment there are contradictions. Conditions for use of automotive air conditioning compressors and general refrigeration compressors, the performance of the following special requirements.
