HCFC-22的替代物THR03的研究

1前言HCFC－22作为空调与热泵机组的制冷剂而广泛存在。按照《蒙特利尔议定书》规定,发达国家将于2020年全面禁用含氢氯氟烃（HCFC）类物质,发展中国家也将于2030年禁用。现有的HCFC－22替代物中,呼声较高的有美国联合信号公司的R410A和R410B,杜邦公司与英国ICI公司的R407C,日本大金公司的R32／R134a。这些替代物各有优缺点,共同的缺陷在于若不采用改型措施,它们的制冷量和性能系数均比HCFC－22低,只有改型后,才有可能达到相同效果甚至更好。国内也已开始HCFC－22的替代研究工作,如西安交大和天津大学等。我们在长期…

THRO3 AS AN ALTERNATIVE TO HCFC-22

A mixture alternative refrigerant to HCFC-22 named THR03 was developed by us.The calculation results of THR03 was compared with HCFC-22 and other alternatives. The standard A/C performance test for THR03 and HCFC-22 in the same air conditioner was done. The flammability and the material compatibility test are also discussed in this paper. It shows that THR03 has zero ODP, low GWP value, non toxicity, non flammability, and good thermal performance. The thermal parameters of THR03 such as the operating temperatures,pressures and volumetric capacity are close to those of HCFC-22. Therefore, THR03 can be applied directly to existing and new air conditioner as "drop-in" alternative.
