Problems solved by technology

Most of the refrigerants we currently use are Freon products. Freon can destroy the ozone layer because of the presence of chlorine (Cl) in the refrigerant, and as the number of chlorine atoms increases, the ability to destroy the ozone layer increases. The increase in the ozone layer will reduce the ability to destroy the ozone layer; the main cause of the greenhouse effect is that the refrigerant generates a large amount of greenhouse gases during the slow oxidation and decomposition process, causing damage to the environment we depend on for survival

Abstract

The invention discloses a mixed refrigerant, which is prepared by mixing the following materials by mass: 10-20 parts of difluoromethane, 20-24 parts of tetrafluoroethane, 8-12 parts of propane, 15-20of liquid-state carbon dioxide, and 3-5 parts of alkyl chromium salicylate. The mixed refrigerant of the present invention does not contain chlorine element, cannot damage ozone layer, has advantagesof good refrigeration effect and strong environmental protection, and cannot damage the environment.

Description

technical field [0001] The invention relates to a refrigerant, in particular to a mixed refrigerant. Background technique [0002] Refrigerants, also known as refrigerants, are commonly known as refrigerants in some areas in the south. It is a working substance that circulates continuously in the refrigeration system and achieves refrigeration through its own state changes. The refrigerant is vaporized by the heat absorbed by the cooling medium (water or air, etc.) in the evaporator, and transfers heat to the surrounding air or water in the condenser to condense. Most of the refrigerants we currently use are Freon products. Freon can destroy the ozone layer because of the presence of chlorine (Cl) in the refrigerant, and as the number of chlorine atoms increases, the ability to destroy the ozone layer increases. The increase in the ozone layer will reduce the ability to destroy the ozone layer; the main cause of the greenhouse effect is that the refrigerant generates a lar...
