RMI analyzed the
feasibility of recovering refrigerants by reclaiming them to prevent leakage of
hydrofluorocarbons (HFCs) gases with very high global warming potentials
(GWPs). With more refrigeration equipment in the world, the need for the
recovery of refrigerants increases. The U.S. and other countries are phasing
down the use of HFCs, but it will be a long time before HFC-containing
equipment is no longer around. The refrigerant R-410A has a GWP of about 2000
and is used in a majority of residential and commercial air conditioning
systems in operation today, including in my own heat pump system. Thus, they
note that demand for legacy refrigerants will persist even as production
declines.
“Meeting this demand will require more effective
management of refrigerant already contained within the installed base of
cooling equipment, where significant volumes remain embedded in equipment at
the end of its useable life. For example, R-410A accounted for 39% of all HFCs
in use in 2022, and more than 80% of residential and small commercial air
conditioning equipment rely on it. Much of this refrigerant could be recovered:
a national contractor survey found that more than half of retiring residential
systems still retain at least 75% of their charge at installation (the
proportion of refrigerant contained within a system).”
They note that the reclaimed refrigerants can be recovered, reclaimed with sufficient purity, and returned to the market.
“Scaling recovery and reclamation can convert recovered
refrigerant from retired systems into a meaningful secondary supply stream,
helping to offset declining production, reduce shortages, and limit price
volatility as supply tightens under the HFC phasedown.”
Reclaimed refrigerants can be
utilized as part of buyback programs. They note that not enough refrigerants
are currently recovered and reclaimed.
“Despite these benefits, reclaimed refrigerant remains
underutilized in the United States, comprising just 3 to 10% of total HFC
consumption as of 2022, and refrigerant recovery rates are well below leading
nations such as Japan, where the recovery is around 40%.”
Thus, reclaiming refrigerants
presents both an economic opportunity and an opportunity to prevent greenhouse gas
emissions.
RMI partnered with OTS
R&D to evaluate the performance of reclaimed refrigerant under controlled
laboratory conditions.
“The results were clear: In both systems, across all
operating conditions, there were no statistically significant differences in
performance between reclaimed and virgin refrigerants. Heating and cooling
capacity, as well as energy efficiency, remained consistent and within expected
uncertainty bounds. These findings demonstrate that reclaimed refrigerant
meeting AHRI 700 standards is chemically equivalent to virgin refrigerant and
delivers equivalent performance, reinforcing its viability as a reliable substitute
for virgin supply.”
Reclaiming refrigerants can
make the transition to lower GWP refrigerants more cost-effective.
“…fully realizing this opportunity will require
sustained coordination and alignment across contractors, distributors,
refrigerant producers and reclaimers, equipment suppliers, and policymakers to
make adoption of reclaimed refrigerant a standardized industry practice.”
Recommendations are given below:
The key finding of the report is that reclaimed refrigerants can be easily and cheaply reprocessed to virgin refrigerant standards. They note that it will be important in the years to come to manage reclaimed refrigerant, which is still in demand but no longer produced, in order to avoid shortages, price volatility, and service disruptions for contractors and building owners. Europe experienced refrigerant price spikes due to its phase-down requirements, but such problems can be avoided by a well-managed reclamation process.
