Title:
COMPOSITION FOR IMPROVING REFRIGERATION ENERGY EFFICIENCY OF HFO1234YF
Document Type and Number:
WIPO Patent Application WO/2021/110008
Kind Code:
A1
Abstract:
Provided is a composition for improving the refrigeration energy efficiency of HFO1234yf, comprising a refrigerant HFO1234yf, a refrigerated lubricating oil PVE, a solubilizer absolute ethanol, and a high-polarity metal protective agent; according to mass percentage, the composition is: HFO1234yf: 85%; PVE: 12%; absolute ethanol: 1%; and metal protective agent: 2%; the metal protective agent is selected from chlorinated poly-α-olefins or chlorinated alkanes, the chlorinated poly-α-olefin being obtained by reacting poly-α-olefin with chlorine gas. The composition can effectively protect the compressor components while reducing the amount of refrigerated lubricating oil in an automobile air-conditioning system, extend its service life; at the same time, the invention can better improve the heat conduction performance of the condenser and the evaporator, increasing the air-conditioning refrigeration coefficient.
