Which of the following refrigerants is allowed in NEW Domestic Small Appliances?

In this topic, which refrigerants are approved for use in new domestic small appliances is determined by safety, compatibility, and regulatory approvals (EPA’s SNAP program). The refrigerant chosen must be non-ozone-depleting and suitable for the low-temperature, compact systems found in household refrigerators and freezers. R-404A fits this category because it is a non-ozone-depleting refrigerant that has historically been approved for use in new domestic small appliances, including freezers, where reliable low-temperature cooling is required. It has a chemical profile and operating characteristics that align with the design of typical household equipment, making it an acceptable option under the regulatory framework for new appliances. The other refrigerants presented don’t meet the criteria for this particular appliance category. R-410A is engineered for air conditioning with higher pressures and materials compatibility requirements not suited to standard domestic small appliances. R-717 (ammonia) is toxic and unsuitable for consumer enclosures. R-600a (isobutane) is flammable, and its use in new domestic small appliances is restricted by safety regulations in many markets, even though it is common in some regions.
