Basic Overview
After the establishment of the Montreal Protocol, some developed countries, after research and comparison of technical personnel in a class of Freon alternatives, the gradual formation of two major categories of hydrofluorocarbon refrigerants and hydrocarbon-based refrigerants. The former is widely used in the United States, Japan and other countries, and the latter is promoted for use in European countries. The ozone layer destruction coefficient of both is zero, and will not cause damage to the ozone layer. In the formation of global warming greenhouse effect coefficient, hydrocarbons are significantly lower than hydrofluorocarbon products. In terms of water solubility, cold condensation pressure, evaporation pressure, exhaust temperature and vacuum requirements and other indicators and manufacturing costs, hydrocarbons also have a greater advantage over HFC products.HCR-12,22 refrigerant is a highly efficient, energy-saving, environmentally friendly hydrocarbon refrigerant developed by SINOPEC Jinling Petrochemical Company Refrigerant, which is the ultimate alternative to CFC, HCFC, HFC refrigerants. Hydrocarbon refrigerant has been widely used in many countries in Europe, America and Asia.
Hydrocarbon refrigerants have been used in automotive air conditioning since 1995; they have successfully replaced R12 and R134a refrigerants in western developed countries.
Other refrigeration, hydrocarbon refrigerant has been widely used by all major refrigerator manufacturers in Europe, 95% of the refrigeration equipment in Germany's refrigerators, refrigerators, freezers and refrigerators are using hydrocarbon refrigerant, and 80% of the freezers in some of the major supermarket chains in the UK have been refrigerated with hydrocarbon refrigerant. Hydrocarbon refrigerant has become the dominant refrigerant technology in Europe; Asian countries such as Thailand, Singapore, India, Malaysia and other countries, hydrocarbon refrigerant has been widely used in central air-conditioning and large refrigeration equipment. Hydrocarbon refrigerant is recognized as: has obvious environmental advantages, and energy saving effect is very prominent. Domestic Haier, Kelong, the two leading enterprises, exported to Europe's refrigerators, air conditioners are mostly hydrocarbon refrigerants. Many countries and regions of the world, the use of hydrocarbon refrigerants for refrigerators, domestic air conditioners and central air conditioning and other refrigeration systems in the use of the ratio is gradually expanding. This high-efficiency, energy-saving, environmentally friendly refrigerant will eventually replace R12, R22 and R134a.
Product Features
■ Completely environmentally friendly
HCR-22 hydrocarbon refrigerant is derived from natural ingredients, from pure sources, deep purification, precision formulation, no damage to the ozone layer, no greenhouse effect, completely environmentally friendly.
■ Economical
By weight, HCR-22 is only about one-third of R12 and R134a refrigerants, making it more economical.
■ Energy efficient
Low freezing point, greater latent heat of evaporation, making the cooling speed faster per unit time; isentropic compression ratio work is small, so that the compressor work easier to extend the service life of the compressor; small molecular weight, mobility is good, the delivery pressure is lower, reducing the load on the compressor. The use of HCR-22 hydrocarbon refrigerant can reduce the system operating costs, energy saving rate of up to 10-20%.
■ Good refrigeration
HCR-22 hydrocarbon refrigerant unit volume, more refrigeration capacity per unit mass. Improved heat transfer performance of the condenser and evaporator. Therefore, HCR-22 hydrocarbon refrigerant is more efficient and has better refrigeration performance.
■ High oil mixing rate
HCR-22 hydrocarbon refrigerant oil mixing rate is very high, and all commonly used refrigeration lubricants (mineral lubricants, synthetic lubricants) are compatible, non-toxic, non-corrosive to metals and oil-resistant rubber. And many refrigerants need special matching refrigerant lubricant, such as the use of improper, there will be problems, the use of hydrocarbon refrigerant can prevent the emergence of refrigerant and refrigerant lubricant is not compatible with the problems caused by.
Currently on the market to use more R134a refrigerant corrosive, the rubber material requirements of the refrigeration system is extremely high, and the commonly used lubricants are not compatible. Therefore, the original infusion of R12 refrigerant car air conditioning replacement with R134a refrigerant must be modified, otherwise the compressor will be damaged, and expensive. In most cases, no matter what type of automobile air conditioning, refrigerators, home air conditioning, central air conditioning and other refrigeration equipment need to be replaced with HCR-22, without retrofitting.
■ Convenient filling
Filling HCR-22 hydrocarbon refrigerant air conditioning system and filling procedures do not need to change, according to the original filling program can be, but it is recommended to use a digital scale to ensure that the filling amount is accurate.
■ Wide range of applications
HCR-22 hydrocarbon refrigerant is a series of products. HCR-12 refrigerant is mainly used for automotive air conditioning, R600a, ar290 refrigerant is mainly used for refrigerators, household air conditioning, central air conditioning, refrigerated trucks and other refrigeration systems.
■ Strong adaptability
Most refrigerants are composed of chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs) mixtures, which have been proved to be unsuitable for use in very hot or tropical areas, while HCR-22 refrigerant has a unique adaptability to very hot climates.
■ Fully compliant
HCR-22 hydrocarbon refrigeration complies with international standards and Australian/New Zealand standards. It is a non-fluorine, high-efficiency, energy-saving, environmentally friendly product
