Non-azeotropic multielement mixed refrigerant

Abstract

The invention discloses a non-azeotropic multielement mixed refrigerant. The non-azeotropic multielement mixed refrigerant is prepared from, by weight, 20-25 parts of heptefluoro propane, 13-20 parts of 1,1,1-halothane, 15-20 parts of pentafluoroethane, 4-8 parts of dichlorotrifluoroethane, 15-20 parts of perfluorocyclobutane, 20-25 parts of dimethyl ether, 4-8 parts of liquid nitrogen, 5-10 parts of carbon dioxide, 15-20 parts of ethylene and 4-6 parts of thiophane. The non-azeotropic multielement mixed refrigerant has much higher refrigerating capacity, excellent comprehensive performance, and a wide application range.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a non-azeotropic multi-element mixed refrigerant. Background technique [0002] Refrigerant is a working substance that circulates continuously in the refrigeration system and achieves refrigeration through its own state changes. Most of the early refrigerants were flammable or toxic, or both, and some were very toxic. Strong corrosion and instability, or some pressure is too high, accidents often occur. Traditional pure refrigerants have limitations in properties and functions, and mixtures are used to prepare refrigerants with better performance. How to choose a formula to make refrigerants have a wider application range and better refrigeration effect is the key to the research of mixed refrigerants. Contents of the invention [0003] The object of the present invention is to provide a non-azeotropic multi-component mixed refrigerant. [0004] The technic...

[0002] Refrigerant is a working substance that circulates continuously in the refrigeration system and achieves refrigeration through its own state changes. Most of the early refrigerants were flammable or toxic, or both, and some were very toxic. Strong corrosion and instability, or some pressure is too high, frequent accidents

The nature and function of traditional pure refrigerants are limited. Using mixtures to prepare refrigerants with better performance, how to choose the formula to make the application range of refrigerants wider and the refrigeration effect better is the key to the research of mixed refrigerants.
