R-410A
Safety and Training Program
As more manufacturers build air conditioning equipment using the HFC R-410A, it is important that contractors and technicians understand the safety, safe handling, proper charging, operating characteristics and proper applications of this refrigerant.
The EPA has established the phase out of the HCFC R-22 with no production or importing beginning in 2020. However, manufacturers of air conditioning equipment must phase out the use of HCFC R-22 in new equipment by January 1, 2010. Many manufacturers have already started this process and are building specially designed systems that utilize R-410A.
The newly designed R-410A systems employ thicker walled tubing, newly developed compressors, components and a higher grade oil that requires different installation and service procedures.
R-410A is an azeotropic mixture and is presently marketed under the brand names of Puron, Suva 410A, and Gentron AZ-20.
These newly manufactured R-410A air conditioning systems will require contractors and technicians to shift to different tools and equipment, safety standards and fundamentals when installing, changing out (retrofitting) older split A/C systems, and repairing systems in the field.
We need to know why R-410A can only be used in equipment specifically designed and constructed for R-410A, and cannot be retrofitted from R-22 systems.
We need to know why R-410A operates at considerably higher pressures and requires the use of special tanks, gauges and recovery equipment, and how to properly handle R-410A for the safety of everyone.
We need to know why all refrigerant flow controls, valves and driers have changed and must be properly applied with newly designed and built compressors.
The AC&R Safety Coalition training program will prepare you for these new challenges, and with successful completion of the certification exam, show evidence of your professional ability to safely handle and work with this new generation of refrigerants and air conditioners. R-410A operates at significantly higher pressures and refrigeration capacity.
The R-410A program is conducted through the auspices of various organizations such as:
COSA
The program is approved by International Comfort Products: Arcoaire, Comfortmaker, Heil, ICP Commercial, Keeprite, Tempstar, Goodman Manufacturing, Amana Heating and Cooling. The Conditioning Contractors of America (ACCA) distribute the Coalition’s training manual.
The ESCO Institute was chosen to provide the grading and publishing services for the coalition.
