The EPA
has established the phase out of the HCFC R-22 with no
production or importing beginning in 2020. However,
equipment manufacturers must phase out the use of HCFC R-22
in new units by January 1, 2010.
R-410A designed systems employ thicker
walled tubing, and compressors capable of withstanding the
higher pressures of R-410A. R-410A systems require different
installation and service procedures.
New equipment that uses R-410A will require service personal
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.
HVAC service persons need to understand the safe handling,
proper charging, operating characteristics, proper
applications, and general use of R-410A refrigerant.
R-410A:
-
Should only be used in equipment specifically designed
and constructed for higher pressure refrigerants.
Operates at considerably higher pressures and requires
the use of special tanks, gauges and recovery equipment.
-
Requires training of installation and service personnel
in the proper and safe handling of R-410A.
-
Needs service personnel to understand why all
refrigerant flow controls, valves and driers have
changed and must be properly applied with newly designed
& built compressors.
-
Many
equipment manufacturers are well aware of the concerns
and safety issues of working with R-410A and other HFC
refrigerants and are requiring installation and service
professionals who purchase their R-410A systems to be
R-410A Certified.
In order to
prepare Air Conditioning Professionals for the challenges presented
by R410A, some of the premier organizations of our industry
have joined to create the AC&R Safety Coalition.
-
Esco Institute
-
Ferris State
University
-
HVAC Excellence
-
Indoor Air Quality Association
-
Industrial Technical Excellence
-
Refrigeration Service Engineers Society (RSES)
By uniting to create a industry wide program, the AC&R Safety
Coalition R-410A Safety Training and Certification program is
offered by Associations, Manufacturers, Schools, Wholesalers and all
facets of the industry including:
-
Air Conditioning Contractors of America (ACCA)
-
Amana Heating and Cooling
-
Bacharach Inc
-
COSA
-
Goodman Manufacturing
-
International Comfort Products
-
United
Association
The AC&R Safety
Coalitions R-410A Safety Training & Certification program
provides the necessary training and practical knowledge to
safely perform service on systems containing R-410A as well
as R-407C and other near azeotropic blends. This program
also includes information on: the R-22 phase-out,
appropriate refrigerant and oil applications, service
techniques, as well as safe handling of R-410-A.
Do not
be denied your opportunity to work on current and future
equipment because you did not opt to get
certified. |
