R-410A
Certification
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.
In order to prepare HVACR
service personnel for these challenges, some of the industry leading
organizations have joined together.
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 training materials were developed by Ferris State University
personnel and published by ESCO press. The certification exam
was developed by HVAC Excellence and is available through the
various coalition members, schools and wholesalers throughout the
United States and Canada.
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.
