Which HC refrigerant is allowed for use in NEW Domestic Small Appliances?

The key idea is regulatory approval for refrigerants in new domestic small appliances, balancing safety, environmental impact, and practicality. R-600a is isobutane, a hydrocarbon with very low global warming potential. When used in small, tightly controlled appliance charges and with proper safety design, it meets the requirements for new domestic refrigerators and freezers. That’s why it’s permitted for these applications. The other refrigerants don’t fit this specific category. R-404A and R-410A are high-GWP HFCs used in other systems and aren’t approved for new domestic small appliances under current guidelines. Ammonia, R-717, is toxic and highly corrosive, making it unsuitable for household appliances. So, isobutane is the one allowed for NEW Domestic Small Appliances.
