What characterizes hydrocarbon refrigerants?

Hydrocarbon refrigerants are characterized as natural refrigerants with low global warming potential (GWP). These refrigerants, which include substances like propane (R-290) and isobutane (R-600a), are derived from natural sources and exhibit a significantly lower impact on global warming compared to many synthetic refrigerants. Their low GWP makes them an environmentally friendly option, aligning with global efforts to reduce greenhouse gas emissions and combat climate change.

In contrast, synthetic refrigerants typically have higher GWPs, which can contribute considerably to global warming when released into the atmosphere. While hydrocarbons are often utilized in various applications, their classification primarily as natural refrigerants with low GWP is the key characteristic.
