- •
R32/R290 (68/32 wt. %) is proposed to replace R410A in household air conditioners.
- •
The ODP of the mixed refrigerant is 0, and the GWP is 22.0% of that of R410A.
- •
The refrigerant charge amount is 30.0%–35.0% lower than that of R410A.
- •
Higher cooling and heating capacities and similar COP are achieved by R32/R290.
- •
Micro-channel heat exchangers achieve 34.1% lower charge and 6.8% higher COP.
