The Refrigerant
Issue:
Putting It Into Perspective For North American Central Air Conditioning
Consumers Overview.
New R-22 is expected to be available for the next 20 years.
Recycled and reclaimed R-22 makes the fluid likely to be available
past the life of all equipment installed until 2010. You can have
confidence buying a system using R-22 ten years from now. It’s simply
not an issue today.
R-22 is not likely to be subjected to major price increases like
R-12 because of its widespread availability and a lengthy phase
out period.
R-410A is a good alternative refrigerant, but it will be years before
it serves the majority of applications.
Homeowners should select heating and air conditioning products based
on efficiency, reliability, durability and dealer recommendations
— not on the refrigerants they use.
The Trane Company will continue to manufacture heating and cooling
products that offer homeowners long-term peace of mind and comfort.
Regulating Refrigerants: A Brief Historical Look At Pertinent
Environmental Treaties.
In 1987 the Montreal Protocol, an international agreement, established
requirements that began the phase out of CFCs (chlorofluorocarbons)
in developed nations. These requirements were modified by various
amendments, leading to the complete phase out of CFC consumption
in 1996. The Copenhagen Amendment (1992) brought HCFCs (hydrochlorofluorocarbons)
under control. These guidelines and amendments have been implemented
in the U.S. through various sections of the Clean Air Act, administered
by the Environmental Protection Agency (EPA).
What This Means For The Heating, Ventilation And Air Conditioning
(HVAC) Industry.
An HCFC known as R-22 has been the refrigerant of choice for residential
heating and cooling systems for more than 40 years. Currently all
major HVAC manufacturers use R-22 in more than 95 percent of the
systems they build. And, even though HCFCs are considerably safer
for the environment (at least 95 percent less damaging to the ozone
layer than CFCs), they still contain chlorine which is an ozone-destroying
chemical. The U.S. regulations under the Clean Air Act targeted
several dates of specific interest to the HVAC industry:
January 1, 1996: A production cap was placed on a variety
of HCFCs, including R-22. This cap limited production in the U.S.
to 15 million tons per year. (Note: To date, demand has not reached
the cap.)
January 1, 2004: The cap will be reduced to a total production
of 10 million tons by banning the use of R141B and R142B, HCFCs
used today as foam blowing agents. This is intended to have no impact
on R-22.
January 1, 2010: HVAC manufacturers can no longer produce
new air conditioners and heat pumps using R-22.
January 1, 2020: Refrigerant manufacturers will no longer
produce R-22 to service existing air conditioners and heat pumps.
(Recovery and recycling will provide refrigerant for servicing installed
systems beyond 2020.) However, and this is important to note, the
Clean Air Act does not allow any refrigerant to be vented into the
atmosphere during installation, service or retirement of equipment.
Therefore, R-22 must be reclaimed (reprocessed to the same purity
levels as new R-22), recycled (for reuse in the same system) or
destroyed. This means there will be plenty of high quality R-22
available for many years to come. Manufacturers can build R-22 products
until 2010 giving consumers a ten-year window in which they can
continue to purchase these products with confidence because of this
availability.
Consumers can also feel confident that R-22 will be available
at a reasonable price beyond 2020.
Many comparisons have been made between the phase out of R-12 (a
CFC) and R-22 (an HCFC), but few similarities actually exist. The
major price increase that occurred with R-12 was largely due to
a high government excise tax that was placed on it in order to accelerate
its phase out. It is highly improbable that this will occur with
R-22. This refrigerant is significantly less damaging to the ozone
layer should it ever escape. And, there is a 20 + year phase out
timeline firmly in place.
Because R-22 will be readily available for many years to come, market
conditions will not be influenced by the same volatility and forced
acceleration campaign that surrounded the phase out of R-12.
The Future Alternative to R-22.
As R-22 is gradually phased out of use over the next two decades,
R-410A will be phased in. R-410A is an HFC (hydrofluorocarbon) and
is considered to be the most likely replacement when R-22 is no
longer used in residential systems. However, as a point of clarification,
units using R-22 will always be serviced with R-22. They should
never need to be changed or retrofitted to a different refrigerant.
Is Puron™* A New Alternative Refrigerant? Puron™* is the trademarked
name that one equipment manufacturer has given to R-410A. However,
developed by a major chemical company who refers to it as Genetron®
AZ-20**, this is not a proprietary refrigerant and is available
for use by the entire HVAC industry. Other manufacturers may adopt
similar positioning taglines as they begin to market new R-410A
products, so you can expect to see a variety of catchy monikers
for R-410A in the coming years.
Why Isn’t R-410A More Widely Used Today?
The transition to R-410A requires that heat pump and air conditioning
systems be redesigned. R-410A is a refrigerant with operating pressures
almost 50 percent higher than R-22. Because of this, a redesign
of the compressor as well as other components is necessary. Additionally,
since R-410A demands special synthetic lubricants for the compressor,
there are compatibility issues with the lubricants, cleaners and
other fluids used in the manufacturing process. All of these issues
must be carefully evaluated.
And, with these significant product and production process changes,
testing and training must change also. Dealers must be schooled
in stricter installation and service techniques required for working
with R-410A units and must obtain new recovery equipment and servicing
tools, as well. The Clean Air Act accommodates the magnitude of
this total effort by allowing a lengthy transition period for the
phase out of R-22.
Another reason R-410A is not widely in use is that industry production
capacity of the refrigerant is limited. It will take several years
for the chemical producers to gear up their production of R-410A
for complete industry transition by 2010.
A Common Sense Approach To Refrigerants.
Beyond regulating the use of certain fluids, the Clean Air Act also
mandated the use of common sense in dealing with refrigerants. By
containing and using refrigerants responsibly — that is, recovering,
recycling, reclaiming with the prevention of leaks — refrigerants
have no ozone depletion consequences. The Clean Air Act outlined
specific refrigerant containment and management practices for HVAC
manufacturers, distributors, dealers and technicians. The single
best thing a homeowner can do for the environment, regardless of
the HVAC fluid used, is to select a reputable dealer who employs
service technicians that have achieved Environmental Protection
Agency (EPA) certification to handle refrigerants.
It’s important to remember that properly installed home comfort
systems rarely develop refrigerant leaks. So a system using either
R-22 or R-410A will have negligible detrimental impact on the environment
for the length of its lifespan.
Put Your Confidence In Trane.
After selecting a reputable dealer, the next best thing a homeowner
can do for the environment is to purchase a high efficiency home
comfort system. With carbon dioxide (CO2 ) emissions tied directly
to energy use, high efficiency heating and air conditioning systems
make a significant contribution toward reducing the global warming
problem.
Trane’s history of manufacturing efficient, environmentally sound
products culminated in the development of the XL 1800 family of
comfort systems more than three years ago. With a SEER up to 18.00,
these are the most energy efficient systems available in the industry.
No other manufacturer has been able to match our gains in efficiency.
This same technical know-how and engineering expertise are being
utilized to develop systems using the new R-410A refrigerant. As
