R410A subs perform well at high ambients

Further tests of low GWP alternatives to R410A in air conditioners have again shown good results at high ambients. The latest results released under phase ll of AHRI’s Low-GWP Alternative Refrigerants Evaluation Programme, compared the performance of R32 and Chemours’ development refrigerants DR-55 and DR-5A in soft optimisation tests against baseline R410A.
