AI Technical Summary
Technical Problem
The existing refrigerant R290 poses safety risks and has insufficient heating performance in household and automotive air conditioners, making it difficult to meet the requirements of the next generation of environmentally friendly refrigerants.
Method used
A mixed refrigerant composed of trans-1,2-difluoroethylene (HFO-1132(E), monofluoroethane (HFC-161), and trifluoromethyl methyl ether (HFE-143a) is used to replace R290 by adjusting the mass ratio of each component.
Benefits of technology
It achieves low GWP, low heat of combustion, and good cooling and heating performance, and can directly replace R290 as a refrigerant without requiring system modifications, thus improving safety and environmental performance.

Abstract
The invention provides a mixed refrigerant as well as a preparation method and application thereof. The mixed refrigerant comprises a first component, a second component and a third component, the first component is trans-1, 2-difluoroethylene (HFO-1132 (E)), the second component is fluoroethane (HFC-161), and the third component is trifluoromethyl methyl ether (HFE-143a); compared with an R290 refrigerant in the prior art, the mixed refrigerant has the advantages that the fire blast hazard is reduced; the mixed refrigerant has the environment-friendly characteristic of low GWP, the GWP is smaller than or equal to 150, and the environment-friendly requirement is met; the thermophysical property and the refrigeration and / or heating cycle performance of the mixed refrigerant are similar to or better than those of R290; the mixed refrigerant can be used for directly replacing an R290 refrigerant.
