It is a fluid that can easily be boiled into a vapor and condensed back into a liquid so the system can use evaporation and condensation to cool your cabin air How does r134a refrigerant work? Because freontm 134a is used in many applications, it is important to review materials of construction for compatibility when designing new equipment, retrofitting existing equipment, or preparing storage and handling facilities. It's a hydrofluorocarbon (hfc) with a relatively low global warming potential (gwp) compared to its predecessor r12. Understand its role in cooling systems and why safer alternatives are emerging.
