Abstract [en]

In a global effort to mitigate global warming refrigerants with a high Global Warming Potential (GWP) will be banned in certain applications. The current European legislation prohibits a refrigerant R404A, which is commonly used in retail food refrigeration systems, from placing on the European market from the 1st of January 2020. Similarly, R404A will be soon unacceptable in retrofit and new supermarket systems in the USA. A refrigerant R449A is a potential replacement for R404A but with the GWP that is significantly lower than R404A's. In this study experimental investigations are conducted during the conversion of a supermarket refrigeration system from R404A to R449A. The performance data is presented and environmental benefits of the conversion are discussed.
