双动力汽车空调压缩机设计及其试验研究

Design and Experiment of Double Power Automobile Air Conditioning Compressor

为实现发动机熄火时汽车空调系统的正常运转,并且降低驻车以及正常行驶时的能源消耗和排气污染,提出一种热/电双动力新型压缩机;以OX-60A-1型涡旋压缩机为原型机,开发一种双动力压缩机,并配备相关控制策略,可以实现发动机驱动模式与电驱动模式的快速切换;针对压缩机的各项性能进行台架试验,并进行空调系统的整车环境模拟试验.结果表明:集成设计的双动力汽车空调压缩机各项性能、整车空调环境指标均达标,从而为该压缩机的实车应用提供了试验依据.

A thermal/electric double-power compressor was designed for the normal operation of the automobile air condi-tioning system when the engine is turned off, which can reduce both energy consumption and exhaust pollution during park-ing or normal driving. The design of the compressor and its control strategy is based on the OX-60A-1,model of scroll-compressor. The new compressor can realize a quick switch between the engine driving mode and the electric driving mode. Its performance has been checked with bench test, and the whole vehicle environment simulation was conducted. The results indicate that the dual-power compressor can reach the functional level of the original machine, and the whole vehicle air conditioning can meet the environmental requirements. The research provides anexperimental basis for the application ofthe double-power compressor on vehicles.
