Description

CMR-04 type ternary non-azeotropic environmental protection refrigerant
Technical field
The invention belongs to refrigerant art, specifically relate to a kind of good thermophysical property CMR-04 type ternary non-azeotropic environmental protection refrigerant that has that constitutes that mixes by several working medium.
Background technology
At present, energy shortage and environmental pollution have become the two large problems that the mankind face, and be energy-conservation and slow down the central topic that Global warming will be the 21 century scientific technological advance.Be faced with stern challenge with the closely-related refrigeration industry of people's daily life.Because the refrigeration agent during some use is to the consumption of atmospheric ozone layer and the influence of Greenhouse effect, simultaneously refrigeration system is annual consumes a large amount of energy, thereby seeks the advanced subject that energy consumption that ideal CFCs substitutes working medium and reduce refrigeration system has become current Engineering Thermophysics subject.
Since 1987, protect ozonosphere, superseded Ozone Depleting Substances for one, reduce the whole world action of Greenhouse effect and just carry out according to the timetable of Montreal protocol agreement in countries in the world.Each relevant industry of China has begun actively to substitute work, strives for obtaining " green mark " that State Bureau of Environmental Protection is issued early, makes the product of oneself become the Green Product that is received by the market.
R12 is a refrigeration industry, especially domestic refrigerator, refrigerator, automative air conditioning and the widely used conventional refrigerants of commercial refrigeration utensil.The refrigeration working medium of existing alternative R12 mainly contains: R134a, R600a and some nearly azeotropic, non-azeotropic binary or ternary mix working medium.
The R134a alternative route need be transformed and change cooling cycle system and major parts (comprising compressor) thereof, lubricating oil, moisture eliminator etc., and directly substitution is used, and brings additional cost to refrigeration industry undoubtedly.In addition, the R134a alternative route is no matter be to compressor production firm, or refrigerator, refrigerator production firm, production technique, control are required too harsh, careless slightly meeting stays serious hidden danger, and the Greenhouse effect of R134a own are big in addition, is not best final alternative route.
R600a belongs to A3 class material, and is inflammable, explosive, and poor stability when aerial content is 1.8%～8.4% (volume ratio), then can burn or explode as spark.But R600a is as the refrigeration agent of refrigerator, with energy-conservation, low noise, atmosphere is not had the advantage of destruction fully, takes the course of its own in numerous user CFCs alternative routes.
Comparatively speaking, the mixing medium alternative route has great superiority, and the improvement design change of tackling compressor in substituting mutually is less, and the distinctive alternating temperature phase-change characteristic of mixing medium provides more wide energy-conservation prospect for refrigerating appliances such as refrigerator, automative air conditionings.The mixing medium alternative route does not need to transform its refrigeration system at refrigerator, automative air conditioning producer, refrigerating efficiency and energy consumption are made moderate progress, demonstrated fully the design of " filling type ", no matter external, domestic at present, mixing medium widely adopts in numerous user CFCs alternative routes.
