What is a CFC certificate?
Chlorofluorocarbon (CFC) certifications give you permission to work on, service and repair equipment that uses chlorofluorocarbon byproducts. HVAC contractors and other industry employees must have this type of certification to work on and install air conditioning units.
Is a CFC certification same as EPA?
The AHAM/NARDA Refrigerant Recovery Certification Program is a test that also includes a downloadable “self-study” guide designed specifically for those who recover refrigerant from appliances grouped as “Type I” by the U.S. Environmental Protection Agency (EPA).
What is EPA Type 2 certification?
Type II. The Type II EPA certification allows you to service high-pressure or very high-pressure systems, excluding automotive AC and small appliances. Like the Type I exam, you will have to get 21 of 25 questions correct to pass.
Is CFC-12 still used today?
While use of CFC-12 in new vehicles has been banned since 1994, some vehicles built before then may still use it if they have not already been retrofitted to a non-ozone depleting refrigerant and they are still on the road.
What is CFC in HVAC?
Chlorofluorocarbons, also referred to as CFCs, are organic compounds composed of chlorine, fluorine, and carbon. Made as volatile derivatives of methane, ethane and propane, chlorofluorocarbons have historically been used as refrigerants in HVAC systems for multiple decades.
Who found CFC?
Sherwood Rowland and Mario J. Molina discovered that chlorofluorocarbons (CFCs) could deplete Earth’s atmospheric ozone layer, which blocks the sun’s damaging ultraviolet rays. When the scientists reported their findings in 1974, CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.
What is EPA Type 1 HVAC?
Type I. HVAC technicians who handle small appliances, such as window or room air conditioners, refrigerators, freezers and dehumidifiers, need Type I certification from the EPA. This covers recovery requirements, recovery techniques and safety.
Why chlorofluorocarbon is used in refrigerator?
They have an exceptionally high heat capacity which makes them effective in the refrigeration process. CFCs were chosen in the 1920s and 30s to replace other chemical refrigerants toxic to humans like ammonia and methyl chloride.
What replaced CFCs in refrigerators?
Chlorofluorocarbon (CFC) refrigerants were commonly used in equipment manufactured before 1995. Equipment manufactured before 2010 may use hydrochlorofluorocarbon (HCFC) refrigerant. Some newer equipment uses hydrofluorocarbon (HFC) refrigerants, which contain no chlorine.
What is a HFC refrigerant?
HFC Refrigerant: HFC refers to the chemical composition of the refrigerant. Hydrofluorocarbon indicates that the refrigerant is comprised of Hydrogen, Fluorine, and Carbon. Common HFC refrigerants are R-32, R- 125, R134a, R-143a, and R-152a. A blend that contains different HFCs is considered an HFC refrigerant.
What is CFC and HFC?
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun.
