What gases are in R134a refrigerant?
1,1,1,2-Tetrafluoroethane is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a somewhat lower global warming potential (1,430, compared to R-12’s GWP of 10,900).
What is HFC-134a gas?
HFC-134a is used in refrigeration and air conditioning systems, as a blowing agent for polyurethane foams, and as a propellant for medical aerosols. HFC-134a is a colorless gas with a faint ethereal odor that may go unnoticed by most individuals. HFC-134a has a very low acute inhalation toxicity.
Is HFC-134a harmful?
Animal studies indicate that HFC-134a has a low level of systemic toxicity following acute, subacute, subchronic, and chronic exposures. For example, neurotoxicity and cardiac sensitization occur after acute exposures to HCF-134a at high concentrations.
Can you inhale tetrafluoroethane?
Accidental inhalation of high concentrations of R-134a (1,1,1,2-tetrafluoroethane) can lead to reactive airways dysfuction syndrome. Symptoms may last for prolong periods, but recovery is expected.
What is the chemical formula for tetrafluoroethane?
CH2FCF3
1,1,1,2-Tetrafluoroethane/Formula
What is refrigerant r404a?
R-404A is a pseudo-azeotropic mixed refrigerant composed of the three ingredients R-125, R-134a, and R-143a, and was developed as a substitute refrigerant for R-502 and R-22, used in commercial refrigerator equipment for low and medium temperature ranges.
Is tetrafluoroethane a HFC?
1,1,1,2-Tetrafluoroethane (also known as norflurane (INN), R-134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone …
What is 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.
Is tetrafluoroethane flammable?
Mixtures with air of the gas 1,1,1,2-tetrafluoroethane are not flammable at atmospheric pressure and temperatures up to 100 °C (212 °F). However, mixtures with high concentrations of air at elevated pressure and/or temperature can be ignited.
What happens if you inhale CFC?
Regularly inhaling high concentrations of Freon can cause conditions such as: breathing difficulty. fluid buildup in your lungs. organ damage.
Is tetrafluoroethane a greenhouse gas?
History and environmental impacts Its concentration in the atmosphere and contribution to radiative forcing have been growing since its introduction. Thus it was included in the IPCC list of greenhouse gases.
Is r410a toxic to humans?
The most common refrigerants, R-410a (Puron) and R-22 (Freon), are neither toxic nor flammable – but they are heavy enough to fill a room and push out the oxygen until you suffocate. Health symptoms and HVAC unit signs can indicate a leak and you should call a professional if you suspect one in your home.
What is tetrafluoroethane used for in air conditioning?
/OTHER TOXICITY INFORMATION/ 1,1,1,2-Tetrafluoroethane is a non-ozone depleting alternative to dichlorodifluoromethane for use as an air conditioning refrigerant and as a propellant in anti-asthmatic and other pharmaceutical preparations.
Is 1/1 1/2-tetrafluoroethane flammable?
Mixtures with air of the gas 1,1,1,2-tetrafluoroethane are not flammable at atmospheric pressure and temperatures up to 100 °C (212 °F).
Is tetrafluoroethane harmful to humans?
1,1,1,2-tetrafluoroethane appears as a colorless gas with a slight ethereal odor. Vapors are heavier than air. Shipped liquefied under own vapor pressure. Flash point 351°F. Inhalation at high concentrations is harmful and may cause heart irregularities, unconsciousness or death without warning. Liquid contact may cause frostbite.
What happens when 1 1 1 2tetrafluoroethane is heated?
Contact of 1,1,1,2-tetrafluoroethane with flames or hot surfaces in excess of 250 °C (482 °F) may cause vapor decomposition and the emission of toxic gases including hydrogen fluoride and carbonyl fluoride.
