Daikin R474a (A2L) approved for EV heat pumps

Daikin, the only company globally to manufacture both air-conditioning systems and refrigerants, has developed a low-GWP refrigerant designed for electric vehicles (EVs) equipped with heat pumps.

R474A (D1V-140) has been developed as an alternative to R1234yf for improved heat pump performance in EVs, particularly in colder climates, where they can lose up to 20 per cent of driving range due to the energy consumption required for cabin comfort and battery thermal management.
