摘　　要： 对CO2制冷剂的应用历史、物性及其热力循环的类型和特点进行介绍。以CO2为制冷剂的系统包括CO2单一工质系统、CO2复叠式系统、CO2自复叠系统及CO2载冷剂系统4种形式,本文结合工程实例比较分析这4种系统各自的优缺点、适宜的应用场合和地域。 TheCO_2 refrigerant＇s application history,physical properties and the types and characteristics of thermodynamic cycle are described. The refrigeration systems using CO_2 as refrigerant mainly include the following four types.mono CO_2 refrigeration system, CO_2 cascaded refrigeration system,CO_2 self-cascaded refrigeration system and CO_2 second- ary refrigerant system. Based on real projects, the advantages, disadvantages, suitable ap- plication situations and geographical area of these four types of CO_2 refrigeration systems are compared and analyzed.
