Résumé

R-404A has been the global industry standard HFC refrigerant for commercial refrigeration in both small and large systems. However, due to its high global warming potential (AR4 100 year GWP = 3922), lower GWP alternatives to R-404A are urgently needed. In particular, the recently enacted European F-Gas regulation requires commercial hermetically sealed systems to use refrigerants with <150 GWP by January 1, 2022. Regulations on high GWP HFCs in other regions are also being proposed. To address this need, a hydrofluoroolefin (HFO) refrigerant mixture with <150 GWP named XL20 (R-454C) has been developed. XL20 is a mixture of HFO-1234yf and HFC-32. HFO-1234yf is in the formulation to dramatically reduce the GWP and HFC-32 has been added to increase the cooling capacity and provide performance close to R-404A. Though XL20 is mildly flammable, the small charge sizes found in self-contained systems are able to accommodate refrigerants with some degree of flammability. This paper will present results from experimental testing of XL20 in a self-contained freezer originally designed to use R404A. Standard performance parameters will be measured and compared to the R-404A baseline, including energy consumption, pressures and temperatures and mass flow rate. Compatibility of XL20 with lubricants and other system materials will also be presented.
