The project aims to provide data, support and information of alternative refrigerants with low GWP at the phasing out of HFC refrigerants for existing and new heating / cooling systems. The focus will be on the new refrigerant thermal properties, requirements for safety of components and energy efficiency.
• Identification of conditions for the phasing out of R134A, R410A and R404A refrigerants and assessment of new refrigerants in term of energy efficiency
• Investigation of the thermal properties and safety of new low-GWP refrigerants and consequence analysis of phasing out of HFC refrigerants and the introduction of new refrigerants on system performance
• Experimental determination of heat transfer and pressure drop for evaporation and condensation with new low GWP refrigerants
• Experimental study of compatibility with polymers, metals and also stability in and outside the system and performance of compressors, heat exchangers and expansion valve with different oils.
