Which refrigerant is noted for having a low ODP, low GWP, and reduced toxicity?

The refrigerant noted for having a low ozone depletion potential (ODP), low global warming potential (GWP), and reduced toxicity is HFOs, or hydrofluoroolefins. HFOs are designed to provide effective cooling while minimizing their environmental impact compared to traditional refrigerants.

HFOs have a low ODP, which means they do not contribute significantly to the depletion of the ozone layer, making them better for environmental sustainability. Their low GWP indicates that they have a minimal effect on global warming when released into the atmosphere, a critical factor as the push for environmentally friendly refrigerants continues.

Additionally, HFOs are characterized by reduced toxicity compared to many older refrigerants. This lower level of toxicity makes them safer for use in residential and commercial applications, aligning with modern regulatory measures aimed at protecting both human health and the environment.

In contrast, other refrigerants, such as HCs (hydrocarbons), while having low ODP and GWP, can present flammability issues and may not be suitable for all applications. R-134a has a moderate GWP and does not exhibit the same environmental friendliness as HFOs. R-717 (ammonia), although it is an efficient refrigerant
