Most hydrocarbons are assumed to be similar to Methane in terms of Atmospheric Lifetime being 12 3 years. It isnt going to slice fingers off, as some people seem to believe. EPAs regulatory requirements for the servicing of MVAC systems apply to all three of these refrigerants. In the United States and globally, many automobile manufacturers are transitioning to the lower-GWP alternatives approved by SNAP, described below. Chlorofluorocarbons ( CFCs) and hydrochlorofluorocarbons ( HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane. In fact, in some areas of refrigeration, this has already begun. 0000001587 00000 n As long as you do not have any major leaks, then you should be fine. To reiterate an earlier point, replacing your AC is a good idea if. Chlorofluorocarbons The production of chlorofluorocarbons, commonly known as CFCs, was banned in the 1990s. Furthermore, the lifespan of the average air conditioner is approximately 15 years. This would be another reason why many experts suggest that those who still own freon-based HVAC units have them replaced. 0000004024 00000 n A refrigerant is a fluid that is used for heat transfer in a cooling system. The gases affected are the higher Global Warming Potential (GWP) HFCs and the higher GWP blends, originally designed as interim retrofit gases. which are future proof from EU regulations, as they contain a very low GWP. Hydrocarbons are assumed to be similar to Methane in terms of Semi-Empirical ODP being < 0(smog chemistry), Blend Calculation using the following information: (a) Hydrocarbons are assumed to be similar to Methane in terms of Atmospheric Lifetime being 12 3 years, (b) Pentane & Isopentane is assumed to have a net GWP over 100-yr to be 4 2. While R-32 is still going to impact the environment, it is said that it only impacts the environment about a third as much as R410A, which certainl does make it a suitable replacement. We'll explain its (important) role in your HVAC system. Pentane, Isopentane & Ethoxyethane (Diethyl ether) is assumed to have a net GWP over 100-yr to be 4 2. 0000006728 00000 n It isnt.
