摘要
CO2作为一种天然制冷剂,是目前制冷剂替代的一个重点研究方向。本文对CO2制冷循环特点进行介绍,通过对CO2涡旋式压缩机的工作特点和影响泄漏的因素进行分析,提出一种可降低CO2涡旋式压缩机气体泄漏量以及提高能效的方法,并进行试验验证。
As a kind of natural refrigerant,using CO2 for refrigerant substitution is an important research direction. The characteristics of CO2 refrigeration cycle are introduced. Through analyzing on the operation characteristic of CO2 scorll compressor and the factors causing leakage,a method which can reduce leakage loss of gas and enhance energy efficiency of C02 scorll compressor is put forward and verified by experiment.
