摘要
本文介绍了ＣＯ_２跨临界循环高压侧压力控制的基本原理；通过循环分析，阐述了不同压力运行条件对制冷量和制冷效率的影响。通过对所得结果的分析论证，提供并优化出一种简单、实用的压力控制调节方案，该方案对汽车空调、热泵系统更有实用意义。
This paper first introduces the basic principle of high-side pressure control and the concept of the optimum pressure. The influence of varying pressure, operating conditions on capacity and efficiency is expatiated through cycle analysis. The paper, according to the results of analysis and demonstrating, put forward a new applied and simple scheme of highside pressure control. The scheme has even more significance for automobile air-condition and heat pump system.
