Experimental Validation of R-474A as a Drop-in Replacement for R-454C
R-474A: the safe, ultra-low GWP alternative refrigerant. Experimental validation in R-454C hydronic heat pumps aims to confirm first simulations, offering a reliable solution where R-290 use is limited by safety or regulation.

Session description
As the RACHP sector accelerates the transition to low-GWP refrigerants, the challenge remains to identify safe, efficient, and regulatory-compliant alternatives that can be deployed across a wide range of applications. While R-290 is increasingly favored for its ultra-low GWP, its A3 flammability classification significantly limits its use in certain residential and commercial settings due to safety concerns and building code restrictions.
This study focuses on R-474A, a newly developed ultra-low GWP, A2L-classified refrigerant, as a complementary solution to R-290, particularly in applications where safety or regulatory constraints make the use of hydrocarbons impractical or prohibited. Following promising computational modeling and system-level performance simulations, a dedicated ...
