Novel environment friendly refrigerating fluid

Abstract

The invention relates to a novel environment friendly refrigerating fluid which is prepared by 1,1-difluoroethane, difluoromethane, pentafluoroethane and carbureted hydrogen component, the carbureted hydrogen component is formed by choosing one or more than one of iso-butane, n-butane, dimethylmethane and propene with arbitrary proportion, and all components are as follows by mass percent: 5-98 percent of 1,1-difluoroethane, 1-60 percent of difluoromethane, 0-30 percent of pentafluoroethane, and 1-20 percent of the carbureted hydrogen component; the ODP value of the refrigerating fluid is zero without damaging atmospheric ozone layer, and compared with HCFC-22 and the existing substitution R407 and R410A, the GWP value is greatly reduced and the environment protecting performance is better; in addition, the charging amount is reduced, the energy efficiency ratio is improved, resource is saved, the novel environment friendly refrigerating fluid can be used as long-term substituent for HCFC-22.

Description

[0001] The application of the present invention is a divisional application with the application number 200810082668X, the application date is February 25, 2008, and the invention-creation name is "a new environment-friendly refrigerant". The original application claimed the right of priority, and the filing date of the earlier application as the basis of the priority right was November 9, 2007, the application number was 200710156803.6, and the country of the earlier application was China. technical field [0002] The present invention relates to a refrigerant, in particular to an environment-friendly refrigerant that can directly replace HCFC-22 in refrigeration, air conditioners, heat pumps and other equipment with basically unchanged system, zero atmospheric ozone destruction potential and low greenhouse effect. The global response to climate warming provides a reliable technology that is easy to popularize and apply, and has quick results. technical background [0003] ...
