Abstract
The present invention discloses ternary non-azeotropic refrigerant which is made by that three substances are together compounded. Calculated according to the mass percent, the ternary non-azeotropic refrigerant of the present invention is composed of R22 (29% to 46%), R152a (30% to 55%) and R124a (7% to 25%). The present invention has the advantages of energy saving, environmental protection, low price, low using cost, good refrigerating effect and big refrigerating capacity; besides, an original refrigeration system can be directly filled without the need of reformation, so the reformation cost is saved for a user of the original refrigeration system.
Description
Technical field
The invention belongs to refrigerant art, specifically relate to a kind of ternary non-azeotropic refrigerant that is composited jointly by three kinds of materials.
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Since 1987, protect ozonosphere, superseded Ozone Depleting Substances for one, reduce the whole world action of Greenhouse effect and just carry out according to the timetable of Montreal protocol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.

Comprehensively above-mentioned, CMR-02 of the present invention has following beneficial effect:
1. energy-conserving and environment-protective: consumption is about 80% of R134a, 70% (the weight meter) of R12.
2. cheap, use cost is low.
3. refrigeration is good, and refrigerating duty is big.
4. former refrigeration system need not to transform, directly perfusion; Save improvement cost for former refrigeration system user.
Reference: the about 68 yuan/kg of R-134a market price, 34 yuan/kg of R-12 market value, and 36 yuan/kg of selling price is estimated in CMR-02 market.
The application notice of refrigeration agent of the present invention:
1. stow away from heat, burning things which may cause a fire disaster are being lower than 40 ℃ the local storage of drying ventilation and are using.
2. be sure not slack tank is incinerated, with blast protection.
3. be sure not jar is deposited in the thermal source face, sun point-blank place can set off an explosion and injure.
Wear eye-protection glasses when 4. operating, wear shield cap, spatter accidentally on eyes or skin, please use a large amount of flushing with clean water immediately.
5. gas replenishment process will be hunted leak, and uses the leak detection of electronics sniffer or lather, as finding gas leakage, inflation again after handling.
6. inflation is inexcessive, observes liquid-sighting glass, sees micro bubble and gets final product.
