部分内循环对整车空调性能的影响分析及实验验证

摘要

本文介绍了汽车空调中部分内循环实现方式，以及部分内循环对整车风量的影响。通过试验和模拟的方式，详细讨论了机械式内循环和电子式内循环两种方式采用部分内循环对整车制冷、加热除雾除霜性能的影响。从整车能耗角度，考察了不同压缩机形式下采用部分内循环对功耗影响。研究成果可以指导汽车空调开发的工程实践。%The method for realizing the vehicle air conditioning partial recirculation was introduced, and the effect of the partial recirculation on the air mass flow rate in the vehicle. Through the experiments and simulation, the influence of partial recirculation on the characteristics of refrigeration, heating defog and defrost for the two ways of mechanical and electronic cycles was analyzed. From the point of the vehicle energy consumption, the effect of partial recirculation on the energy consumption under the conditions of different compressors was investigated. The research results may provide good guidance for the development of air conditioning for vehicles.
