Problems solved by technology

[0003] So far, no ideal final substitute for R12 has been found or developed, but countries around the world have developed multiple mixed refrigerants, some of which have been considered as new mixed refrigerants that are likely to replace Freon R12, such as U.S. Patent No. 4810403, etc. disclose such as R22/R124/R152a mixed refrigerants, and Japanese Patent Laid-Open No. 52-70466 discloses R22/R115/CH 3 Cl may be a mixed refrigerant with practical value, but these mixed refrigerants still have certain limi...

Embodiment 1

[0022] According to the mixed refrigerant composed of 43.5% (weight) of R22, 8.5% (weight) of R152a, 5% (weight) of R142b, and 43% (weight) of RC318, it can save energy by 58.5-62% in heat pumps and air conditioners through application tests. It can save energy by 57-62% in the refrigerating device. After a certain unit uses the mixed refrigerant of this embodiment to replace other proportioned mixed refrigerants disclosed in CN1030204C, the energy-saving effect increases by 28%.

Embodiment 2

[0024] According to the mixed refrigerant composed of R22 45% (weight), R152a 7% (weight), R142b 5.5% (weight), and RC318 42.5% (weight), it can save energy by 59-62.5% in heat pumps and air conditioners through application tests. It can save energy by 58.5-62% in the refrigerating device. After a company uses the mixed refrigerant of this embodiment to replace other mixed refrigerants disclosed in CN1030204C, the energy-saving effect increases by 29%.

Embodiment 3

[0026] According to the mixed refrigerant composed of R22 46% (weight), R152a 8% (weight), R142b 4.5% (weight), and RC318 41.5% (weight), it can save energy by 58-61.5% in heat pumps and air conditioners through application tests. It can save energy by 58-61.5% in the refrigerating device, and after a unit uses the mixed refrigerant of this embodiment to replace other proportioned mixed refrigerants disclosed in CN1030204C, its energy-saving effect increases by 26%.

Abstract

The present invention is one kind of energy-saving environment-protecting zeotropic mixture refrigerant consists of chlorobifluoromethane 43.0-46.5 wt%, 1, 1-difluorethane 6.0-9.0 wt%, 1-chloro-1, 1- difluorethane 4.0-6.0 wt%, and octafluorocyclobutane 41.0-44.0 wt%. The refrigerant has obvious energy saving effect, excellent environment protecting performance and excellent comprehensive performance, and may be used as new generation of refrigerant to replace CFC widely used in various refrigerator, heat pump and air conditioner.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a new generation of energy-saving and environment-friendly non-azeotropic mixed refrigerant. Background technique [0002] As we all know, refrigerants used in refrigeration, heat pumps and air conditioners have long used Freon R12 (CCl 2 f 2 ), has been used for sixty years, but it is found that mankind is facing the most serious environmental crisis in history, especially because the extensive use of Freon R12 has seriously damaged the atmospheric ozone layer, and it is worrying that the destruction of the ozone layer has a negative impact on human survival. It caused great harm, so countries around the world paid special attention and signed the Montreal Protocol. According to the Montreal Protocol, among the ozone-depleting substances, chlorofluorocarbons including Freon R12 are the most harmful, and they are absolutely controlled and prohibited. Substances, and it is...
