Energy-saving environment-protecting abrasion-proof canned carbon-hydrogen refrigerant

Abstract

The invention relates to an energy-saving environmental-protection type abrasion resistant canned hydrocarbon refrigerant, which comprises propane and isobutane. The energy-saving environmentally-protective abrasion resistant canned hydrocarbon refrigerant is characterized in that the energy-saving environmentally-protective abrasion resistant canned hydrocarbon refrigerant further comprises low temperature refrigeration lubricating oil; the propane accounts for 54 to 65 percent; the isobutane accounts for 30 to 40 percent, and the low temperature refrigeration lubricating oil accounts for 3 to 8 percent. The hydrocarbon refrigerant is prepared by mixing mixed alkane with certain proportion and the low-temperature refrigeration lubricating oil in proper amount, thus effectively solving the problem of the prior hydrocarbon refrigerant that a compressor is abraded frequently and a cylinder bore is scuffed frequently due to the characteristics of being too dry and excellent oil solubility, The hydrocarbon refrigerant with mixed alkane disclosed by the invention belongs to natural working fluid, is free of fluorine without influence on warming-up of the global climate. Compared with R12 and R134a, the freezing point is lower; the latent heat of vaporization is larger; the specific energy of constant entropy compression is smaller so that the compressor works more easily. The flowing property is better; the delivery pressure is lower; the load of the compressor is lower; fuel consumption is reduced and the energy-saving rate can reach 10 percent to 20 percent when the air conditioners are running.

Description

technical field [0001] The invention relates to a refrigerant, in particular to an energy-saving, environment-friendly, wear-resistant canned hydrocarbon refrigerant. Background technique [0002] After the establishment of the "Montreal Protocol", technical personnel in some developed countries, after research and comparison, gradually formed two categories of refrigerants based on hydrocarbons and hydrofluorocarbons as a substitute for Freon. Among them, the former is highly recommended by European countries, and the latter is widely used in the United States, Japan and other countries. Both have zero ozone depletion coefficients and will not cause damage to the ozone layer. In terms of the greenhouse effect coefficient of global warming, hydrocarbons are significantly lower than hydrofluorocarbon products. Hydrocarbons also have greater advantages over hydrofluorocarbons in terms of water solubility, condensation pressure, evaporation pressure, exhaust temperature, and ...

Problems solved by technology

It is difficult and unrealistic to require every user to pay attention to replenishing lubricating oil, so this problem has not been well solved, which is not conducive to the promotion and use of hydrocarbon refrigerants.
