Environmental-protective and energy-saving cryogen

Abstract

An environmental protective and energy-saving refrigerant consists of multiple mixture R152a 20-60wt%, R290 10-30wt%, R32 10-20wt% and R1270 5-20wt%. The process is carried out by proportioning the components, mixing physically and canning. It is safe, energy saving and non-toxic. It has excellent thermal circulation and refrigeration performances and better condensing pressure.

Description

Technical field: [0001] The invention relates to a refrigerant, in particular to an environment-friendly and energy-saving refrigerant used in refrigeration, air conditioning, heat pump and other equipment. Background technique: [0002] In the prior art, refrigerants R12, R22 and R502 have been used for a long time in equipment such as refrigeration, air conditioning and heat pumps, and low-temperature refrigeration systems. These refrigerants have been widely used. In 1974, they were found to be harmful to the ozone layer of the atmosphere. effect and have a greenhouse effect. For this reason, the international community has jointly imposed restrictions and decided that developing countries (including China) will basically ban refrigerants R12 and R22 from 2020. China joined the "Montreal Protocol" in 1991, and in 1993 the State Council approved "China's Ozone Depleting Substance Phase-Out Countries", which stipulates that all CFCs will be phased out by 2010 at the latest...

Problems solved by technology

However, these refrigerants also have some problems. For example, the working pressure of R410a is very high; The air-conditioning equipment needs to be modified more before it can be applied, which will bring many difficulties to the actual application and popularization
