Abstract

The invention provides a refrigerating agent composite which is used for replacing R410A in household air-conditioner / heat pump or other systems. The refrigerating agent is composed of difluoromethane (R32) and ethyl fluoride (R161); the preparation method is implemented by carrying out physical mixing on the above components at liquid phase in corresponding proportion. The invention does not damage ozonosphere in atmosphere, has lower GWP value, can reduce emission of greenhouse gases by above 69%, has thermotechnical parameters approximate to R410A, is compatible with pipelines, parts and lubricant of existing R410A system, can realize direct filling, is superior to R410A in thermotechnical performance, and has higher refrigerating efficiency and better energy saving effect after replacement.

Description

technical field [0001] The invention belongs to the field of refrigerants and relates to a refrigerant composition, in particular to a refrigerant composition used in refrigeration and air-conditioning systems such as household air conditioners / heat pumps to replace R410A. Background technique [0002] At the "Montreal Protocol" Conference of the Parties held in September 2007, a new resolution was reached on the phase-out and ban of HCFCs, which stipulated that developed countries will completely stop the production and consumption of non-raw material HCFCs by 2020, including Developing countries, including China, should freeze the production and consumption of non-raw material HCFCs (about 70% of which are R22) at the average level of 2009 and 2010 in 2013, and completely phase them out in 2030. It can be seen that the replacement of R22 by the international community is imminent, and some developed countries such as the European Union have banned R22 in advance, refrigera...
