介绍了国内外人工冰场的发展现状，特别是CO 2制冷剂在人工冰场制冷系统中的应用情况。从节能和环保的角度阐述了CO 2用于人工冰场制冷系统的重要意义。总结了常规冰场和CO 2冰场制冷系统的分类及CO 2冰场制冷系统的热回收应用。最后在文献数据基础上比较分析了常规及CO 2冰场制冷系统的性能系数与运行经济性。%The development situation of ice rink at home and abroad, especially the artificial ice rink refrigeration system application using CO2refrigerant is introduced. From the point of energy conservation and environmental protection, the significance of CO2in ice rink refrigeration system application is elaborated. The common categories of conventional and CO2ice rink refrigeration system are discussed, also including heat recovery application in CO2ice rink refrigeration system. Finally, based on literature data, the coefficient of performance and the function economy of conventional and CO2ice rink refrigeration systems are compared and analyzed.
