S5. the mixed material in S4 is sampled, detects its interior ethane, whether the content of propylene meets corresponding parts by weight
Proportioning, the mixed material obtained if meeting are the refrigerant of the replacement R32.
Wherein, the detection in S1 and S5 utilizes gas chromatograph to complete.
Specifically, S1 moderate purities reach refrigerant grade standard refer to the purity of each raw material reach 99.96wt% with
On.
Specifically, the cleaning reagent in S2 is any raw material that S1 moderate purities reach refrigerant grade standard.
Specifically, it refers to that the absolute pressure in pressure vessel is down to 0-0.15Pa to be vacuumized in S3.
Above-mentioned preparation method introduces " drop in " (being directly injected into) and " add in " (at any time when carrying out R32 replacements
Addition) concept, i.e., it directly injects in the former refrigeration equipment using R32 or adds refrigerant provided by the invention at any time and can make
With any parts of refrigeration equipment need not be replaced.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) air-conditioning refrigerant provided by the invention is tested after directly substituting R32 on original equipment, because its evaporation latent heat is big,
Faster, therefore its high cooling efficiency is proved through company project research center by 2 years test datas unit interval cooling rate,
Fractional energy savings reaches 18-20%, good energy-conserving effect；Therefore refrigerant provided by the invention will not produce while do not destroy ozone layer
Raw greenhouse effects.
(2) air-conditioning refrigerant provided by the invention is because of high cooling efficiency, therefore 55% that its filling weight is R32, economical real
Favour.
(3) the refrigerating capacity ratio R32 of refrigerant provided by the invention is higher by 4% or more, compressor can be made to unload in advance, simultaneously
Refrigerant provided by the invention is that its average molecular weight ratio of mix refrigerant R32 is small by 59%, and mobile performance is more preferable, discharge pressure
It is low, the operating pressure of compressor is alleviated, unloading in advance and mitigating operating pressure can effectively extend the service life of compressor.
(4) ethane in refrigerant provided by the invention, the water solubility of propylene are small, will not with use R32 original equipment in moisten
Chemical action occurs for lubricating oil, compatible with the lubricating oil in original equipment, therefore it need not replace any original refrigeration equipment, not adjust
It is whole to come into operation, avoid the unnecessary economy brought to user due to the huge apparatus caused by refrigerant is replaced wastes
Loss.
