Where HCFCs are used


This list is a quick reference for National Ozone Units to help identify applications where HCFCs might be used in their countries, which in turn helps to identify the HCFC-consuming enterprises which need to be involved in the preparation of the national HCFC Phase out Management Plan (HPMP).

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.

HCFCs are used in the following sectors, either as single components or in blends:

  Fire extinguishing

The specific applications where HCFCs may be used 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)
  Refrigerants for deep mines
  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, cold stores
  Refrigerated transport and 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

HCFC-225 ca/cb
  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)
  Refrigerants for deep mines
  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

The overall objective of the project is to contribute towards the reduction of direct and indirect releases or emissions of ozone depleting substances (HCFCs) and greenhouse gases (HCFCs and HFCs) both through promotion of zero ozone depletion potential (ODP) and low global warming potential (GWP) alternatives as well as promotion of best practices and better engineered and energy efficient technology.

Infos on HFCs

HFCs are fluorocarbons, used as replacements to HCFCs. Their emissions are controlled under the Kyoto Protocol. HFCs are GHGs but do not deplete the ozone layer
