High-performance air-conditioning refrigerants with low GWP.

Number: 1217

Author(s) : LOW R.

Summary

The average Global Warming Potential (GWP) of all refrigerants used must reduce to about 300 if international regulatory requirements are to be met (Cohr-Pachai, 2018). Yet as GWP reduces so must the focus be maintained on ensuring that the energy efficiency of any new refrigerant does not result in a perverse increase in indirect emissions of CO2 from added power consumption. Koura has new air-conditioning refrigerants in active development which offer comparable cooling capacity with energy efficiency increased compared to R- 410A whilst having a GWP of 300 or lower. This paper covers the refrigerants’ properties and performance by cycle modelling and practical testing in systems. Initial results of lubricant and materials compatibility will also be presented and discussed in the conference presentation.
