Environment-friendly refrigeration composition capable of replacing R410A

Abstract

The invention discloses an environment-friendly refrigeration composition capable of replacing R410A. The refrigeration composition is composed of HFC-161, a second component and a third component. The second component is HFO-1234yf and / or HFO-1234ze (E). The third component is HFC-32 and / or HFO-1123. The refrigeration composition is composed of, by mass, 5%-50% of the HFC-161; 5%-20% of the second component; and 40%-90% of the third component. The refrigerating composition has the advantages that the refrigerating performance and the heating performance are excellent, and in-situ replacement of an original system can be achieved.

Description

technical field [0001] The invention relates to the field of refrigerants, in particular to an environmentally friendly refrigeration composition that can replace R410A in situ and be used in a system that originally used R410A. Background technique [0002] In recent years, global warming has been increasing. Following the phase-out of CFC refrigerants (such as CFC-11 and CFC-12), according to the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, HCFC refrigerants will also gradually was replaced. As a typical representative of HCFC refrigerants, HCFC-22 is widely used in refrigeration equipment such as air conditioners because of its non-flammable, non-toxic, and excellent thermal properties. However, HCFC-22 not only has a certain destructive effect on the atmospheric ozone layer, but its GWP (Global Warming Potential) is as high as 1790, which has a strong greenhouse effect. According to the Montreal Agreement, HCFC-22 will be phased out in 2020. State...

Problems solved by technology

[0003] Chinese patent CN100500792C discloses a refrigerant composition replacing HCFC-22, consisting of 5-25% HFC-161, 25-50% HFC-125 and 40 Composition of ~50% HFC-32, the pressure of this composition is similar to that of HCFC-22, and it can replace HCFC-22 without changing the main components of the system, but the GWP value of this composition is still as high as 1200-2000, and the greenhouse effect is significant

[0004] Chinese patent CN101649190B discloses a refrigerant to replace R22, which consists of 35-50% propylene, 30-40% propane, 5-16% 1,1,1 , 2-tetrafluoroethane, 5-10% 1,1,1-trifluoroethane, and liquid CO2, which can be directly filled in R22 equipment, but its GWP value is still as high as 1080-1180, and the greenhouse effect is significant

[0006] Chinese patent CN105018036B discloses a heat transfer fluid to replace R410, which is composed of 40-58% 1234yf, 40-50% R32 and 2-10% R152. Refrigerant can replace R410, but its cooling effect and GWP value are not disclosed

However, none of the above compositions disclosed the possibility of replacing R410A in situ and the unit refrigeration capacity of the composition
