How to Safely Switch to A2L Refrigerants

Sustainability, Meet Safety

New and evolving environmental regulations have created shifting ground beneath the feet of any individual or business using refrigerants. Fortunately, hydrofluoroolefin (HFO) chemistry has led to the emergence of a new generation of refrigerants for air conditioning and refrigeration systems. These HFO refrigerants offer high-performing and environmentally sustainable alternatives to traditional hydrofluorocarbon (HFC) and hydrochlorofluorocarbon (HCFC) refrigerants, which are being phased down and phased out in developing countries.

While this new generation of refrigerants offers superior reliability, consistency, and efficiency, selecting and implementing a new refrigerant isn't as easy as topping off an existing HFC or HCFC-based system with an HFO alternative.

Many factors must be considered in making the switch. This white paper aims to explain he various refrigerant options in the marketplace, how to assess their suitability for a range of applications, and how to safely transition an existing system to a new refrigerant. Learn the difference between ASHRAE safety ratings—including the mildly flammable A2L classification that is assigned to many HFO refrigerants—and how to properly handle these refrigerants to eliminate risk.
