Abstract

An environmental-protective cryogen for substituting CFC-12 consists of HFC-161 and1,1-HFC-152a and hydrocarbon, which is selected from one or above one of HC-600a, HC-600 and HC-290. The ODP value of cryogen is zero, GWP value is much less than CFC-12 and HFC-134a. It has excellent environmental and thermal performances, thermal-power parameter, and it saves energy. It can be used for crude HFC-134a, ester oil system, crude CFC-12 and mineral oil system or CFC-12 substitute.

Description

technical field

[0001] The invention relates to a working medium of a refrigeration cycle, in particular to a novel environment-friendly refrigerant replacing CFC-12. Background technique

[0002] Among chlorofluorocarbon (CFC) refrigerants, CFC-12 has long been widely used in automotive air conditioners, household refrigerators and industrial cold storage due to its excellent thermal performance, stable chemical performance, non-toxicity, and non-flammability.

[0003] However, because CFC-12 has a certain destructive effect on the ozone layer in the atmospheric stratosphere, its ODP (Ozone Depletion Potential) value is 0.82 (with CFC-11 as the reference value 1.0), so "About Ozone Depletion Substances of the Montreal Protocol will contain CFC-12 CFC s As the first batch of eliminated substances. At present, developed countries have stopped the production of CFC-12, and my country is also reducing its production and usage year by year, and plans to...
