Abstract

The invention discloses an environment-friendly mixed refrigerant containing trifluoroiodomethane and a preparation method of the environment-friendly mixed refrigerant. The mixed refrigerant is prepared from the following substances in parts by weight: 0.1 to 37 parts of trifluoroiodomethane, 0.1 to 87 parts of difluoromethane, 1 to 26 parts of fluoroethane and 0.1 to 12 parts of fluoromethyl ether. The refrigerant provided by the invention has the characteristics of low GWP value, high safety and low toxicity.

Description

technical field [0001] The invention relates to a refrigerant, in particular to an environmentally friendly mixed refrigerant containing trifluoroiodomethane and a preparation method thereof. Background technique [0002] Refrigerant, also known as refrigerant, is the working medium of the refrigeration cycle. It uses the phase change of the refrigerant to transfer heat, that is, the refrigerant absorbs heat when it vaporizes in the evaporator, and releases heat when it condenses in the condenser. There are more than 80 kinds of substances that can be used as refrigerants at present, the most commonly used ones are ammonia, Freon, water and a few hydrocarbons. R22 refrigerant has been widely used in air conditioning and other fields due to its excellent thermal and transmission properties. However, R22 is a typical CFCs substance, which destroys the ozone layer and has a greenhouse effect. It is restricted by the Montreal Protocol and the Kyoto Protocol. In developed count...
