The Transition to Low-GWP Refrigerants

Share

Just as the HVAC industry in the United States transitioned from ozone-depleting hydrochlorofluorocarbon (HCFC) refrigerants to hydrofluorocarbon (HFC) refrigerants, it will now transition from HFCs to low global warming potential (GWP) refrigerants. The specific timing, however, is a hotly debated industry issue.

This white paper discusses:

  • The phase-out schedule for HFC refrigerants
  • Johnson Controls decision to move forward with R-454B in new residential and commercial HVAC equipment
  • Benefits of R-454B
  • Pending manufacturing cutoff dates for the unitary sector
  • Updating codes and standards to ensure a safe transition
  • Training and licensing installing contractors to properly use the new refrigerant
