摘　　要：本文公开了霍尼韦尔正在开发的高性能、低环境影响的新型制冷剂的最新进展。新工质保留了现有氟烃制冷剂的高效率、同时在全球变暖效应方面有显著改善,且可燃性也比易燃的碳氢化合物低很多。本文将讨论R134a、R404A和R410A在家用冰箱、自动售卖机、家用空气调节和商用制冷应用方面的替代制冷剂的研究成果,同时还将比较和对比替代制冷剂的物理和化学性质、热力学性质以及不同应用下的实验结果。New refrigeration system working fluids with the positive attributes of both high thermal performance and low environmental impact are currently in development. These materials maintain the high level of system efficiency we are accustomed to with fluorocarbon refrigerants but with significantly lower global warming impact than current refrigerants. These fluids exhibit significantly lower flammability characteristics than the much more flammable hydrocarbons. Replacements for R134a as well as R404A and R410A will be discussed for various applications including household refrigerators, vending machines, residential air conditioning, and commercial refrigeration applications. Chemical and physical properties, including thermodynamic data, as well as some experimental results for the various refrigeration applications are compared and contrasted.
