Problems solved by technology

This is because the existing refrigeration system is almost based on the traditional refrigerant (fluorine-containing) as the design parameter. After replacing the hydrocarbon refrigerant, the original system will lose lubrication. During the promotion and use, every user is required to pay attention to replenishing lubricating oil. It is more difficult, which is unfavorable to the promotion and use of hydrocarbon refrigerants, but this problem has not been well resolved

Abstract

The invention relates to a refrigerant, in particular to an energy-saving environment-friendly abrasion-resistant canned hydrocarbon refrigerant which is prepared by the following raw materials by weight: 54-65% of propane, 30-40% of isobutene and 3-8% of low-temperature freezing lubricating oil, wherein the pour point of the low-temperature freezing lubricating oil is at the temperature ranging from -25DEGC to -36 DEG C. The hydrocarbon refrigerant is prepared by adding mixed alkane with proper proportion into proper low-temperature freezing lubricating oil and effectively solves the problem that abrasion and cylinder score often happen to a compressor due to the fact that the existing hydrocarbon refrigerant has the characteristics of being too dry and good in oil solubility.

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 ...
