Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to these specific implementations. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

[0033] The refrigeration composition provided by the present invention is prepared by mixing fluoroethane (R161), 1,1,2-trifluoroethylene (R1123), the third component and the fourth component in a liquid state according to a certain proportion for physical mixing.

[0034] The third component is selected from 1,1-difluoroethane (R152a) and / or difluoromethane (R32);

[0035] The fourth component is selected from at least one of trifluoroiodomethane (CF3I), fluoromethane (R41) and carbon dioxide (CO2).

[0036] Table 1 shows the composition ratio of the environment-friendly compositions of Examples 1-9 of the present invention, and Ta...

Abstract

The invention discloses an environment-friendly refrigerating composition with excellent refrigerating and heating performance. The environment-friendly refrigerating composition comprises the following components: (a) 1 to 30% of fluoroethane; (b) 1 to 60% of 1, 1, 2-trifluoroethylene; (c) 1 to 25%of a third component which is selected from 1, 1-difluoroethane and / or difluoromethane; and (d) 1 to 50% of a fourth componentwhich is selected from at least one of trifluoroiodomethane, fluoromethane or carbon dioxide. The ODP value of the environment-friendly refrigerating composition is 0, the GWP value is smaller than or equal to 200, and the environment-friendly refrigerating composition has excellent refrigerating and heating performance at the same time, can be used as a refrigerant for replacing R410A and is particularly suitable for being used as a heat transfer medium of a new energy automobile air conditioner.

Description

technical field [0001] The invention relates to the field of refrigerants, in particular to a refrigerant comprising fluoroethane, 1,1,2-trifluoroethylene, 1,1-difluoroethane and / or difluoromethane, trifluoroiodomethane, fluoromethane and An environmentally friendly refrigerating composition of at least one type of carbon dioxide, the environmentally friendly composition is suitable for use as a heat transfer working medium for heat pumps and air conditioners, and is particularly suitable for replacing R410A as a heat transfer working medium for new energy vehicle air conditioning systems. Background technique [0002] In November 2017, the "Montreal" Kigali Amendment reached the conditions for entry into force. This international convention aimed at reducing HFCs substances came into effect on January 1, 2019, which means that HFCs and combinations composed of HFCs are currently commonly used The world is facing controlled and gradual reduction, that is, the development of ...
