Problems solved by technology

Developed countries use government financial subsidies to replace new energy-saving and environmentally-friendly air conditioners, but in my country so far only environmentally friendly and non-energy-saving air conditioners account for only 5% of the total number of air conditioners. The current economic status of our country cannot replace new air conditioners with national financial subsidies. In order to meet the requirements of building energy saving

Abstract

The invention belongs to the technical field of refrigerants used by fixed refrigeration compressors, and specifically relates to a refrigerant replacing R410, and a preparation method and an application for the refrigerant. The refrigerant replacing the R410 comprises the following components in percentages by weight: 20 to 36% of fluoroethane, 44 to 61% of difluoroethane and 18 to 32% of trifluoroiodomethane. The refrigerant (R-612) replacing the R410 provided by the invention has a zero ozone loss value (ODP) and an extremely low greenhouse effect (GWP), fills the blank of energy-saving andenvironmentally-friendly refrigerants at home and abroad, and has the characteristics of greenness, environmental protection, high efficiency, energy conservation and good market prospect.

Description

technical field [0001] The invention belongs to the technical field of refrigerants used in stationary refrigeration compressors, and in particular relates to a refrigerant replacing R410 and its preparation method and application.
