HCFCs are used in the following sectors, either as single components
or in blends:
| |
Feedstock |
| |
Refrigeration |
| |
Foams |
| |
Solvents |
| |
Fire
extinguishing |
| |
Sterliants |
While many HCFCs are in the list of controlled substances, only
HCFC-22, -123,
-124, -141b,
-142b and -225ca/cb
are consumed in significant quantities. The specific applications
where they may be found include:
| |
Refrigerant for small
air conditioning equipment , such as window-mounted and through-the-wall
air conditioners, non-ducted and ducted as well as packaged
air conditioners |
| |
Refrigerant for small
water chillers of about 100 kW refrigeration capacity up to
the capacity of centrifugal chillers |
| |
Commercial refrigeration
equipment |
| |
Smaller chillers |
| |
Heating only heat pumps |
| |
Industrial refrigeration
equipment (largely overlapping with the above market for smaller
chillers) |
| |
Commercial refrigeration
, such as small, plug-in units (e.g. soft drink coolers and
ice cream freezers) as well as systems installed on site in
smaller shops as well as super- and hypermarkets |
| |
Mobile air conditioning
equipment (but not automobiles) such as reefer ships, refrigerated
containers, refrigerated railcars, road transport, air conditioning
in trains, air conditioning in buses and merchant marine and
fishing vessels |
| |
Mixture component in some
drop-in replacements for CFC-12 and R-502 |
| |
Used in original equipment
manufacture (OEM) |
| |
Foam applications, e.g.
extruded polystyrene foams, rigid foam applications in domestic
refrigeration |
| |
Feedstock used for the
production of PTFE (polytetrafluoroethylene) |
|
| |
Blowing agent in rigid
polyurethane foams (used largely for insulation purposes) |
| |
Blowing agent in integral
skin foams (used for example in manufacture of soles of shoes,
but also internal parts of automobiles such as dashboards, steering
wheels etc.) |
| |
Blowing agent for phenolic
foam (minor use) |
| |
Significant use in solvent
applications for purposes such as lubricants, coatings and cleaning
fluids for aircraft maintenance and electrical, electronic or
photographic equipment, mould release agents, document preservation
sprays.
|
|
| |
Blowing agent in extruded
polystyrene board foam |
| |
Blowing agent in polyethylene
foam production (minor use) |
| |
A refrigerant mixture
component in some CFC-12 drop-in replacements |
| |
Feedstock used for the
manufacture of VF2, which is then used to make the engineering
fluoro-polymer PVdF |
|
| |
Speciality solvent in
the manufacture and maintenance of high-value electrical, precision,
and optical equipment in aerospace, military and specialized
industry applications (e.g. precision inertial guidance systems,
and oxygen components and piping systems in aircraft carriers
and hospital ships). |
| |
Cleaning some implantable
or surgical medical devices and plastic medical equipment that
are not compatible with other solvent |
|
| |
Low-pressure refrigerant
in large air conditioning chillers (centrifugal chillers) |
| |
Portable fire extinguishers
in applications such as used in telecommunication facilities,
computer rooms, office buildings, retail facilities, libraries,
art galleries, warehouses, industrial facilities, rail cars,
automobiles, automobile racing, delivery trucks, long- and short-haul
trucks, power generation plants, commercial shipping, pleasure
craft, airport gates and airport ramps, military. |
| |
Very minor use as an ingredient
in specialty solvents |
| |
Feedstock for pharmaceutical
and agricultural products |
|
| |
Refrigerant mixture component
in some drop-in replacements |
| |
Some heat pumps |
| |
Some special air conditioning
equipment |
| |
Component of some sterilant
mixtures |
| |
Minor use as a fire extinguishant |
