Thus, a chemical with an ODP over 1.0 will degrade the ozone layer more than CFC-11. 1) Production of R11 or CFC-11 was halted by the clean air act on January 1, 1996 2) Production of R12 or CFC-12 (Dichlorodifluoromethane) was halted by the clean air act on January 1, 1996 3) R22 or HCFC-22 is a single component HCFC refrigerant with low ozone depletion potential. Their predecessors were the refrigerant classes CFCs, HCFCs, and HFCs. Carbon tetrachloride has an ODP of 1.2, and methyl chloroform's ODP is 0.11. Group I. chlorofluorocarbon-11 (CFC–11) chlorofluorocarbon-12 (CFC–12) chlorofluorocarbon-113 (CFC–113) chlorofluorocarbon-114 (CFC… It is used where low freezing point and non-corrosive properties are important. Within 60 days after November 15, 1990, the Administrator shall publish an initial list of class I substances, which list shall contain the following substances:. Refrigerants fall into one of following four main categories: A blend that contains a CFC and any other product is still considered a CFC Types of Refrigerants. HFOs are widely considered to be the refrigerant of the future. In the last decade the manufacturer developed different types of refrigerants. Other CFCs and HCFCs have ODPs that range from 0.01 to 1.0. Thus, the ODP of CFC-11 is defined to be 1.0. List of HFC refrigerants: HFC refrigerant (hydrofluorocarbons) is the third generation of fluorinated refrigerants. Chlorofluorocarbons (CFC’s) and hydrochlorofluorocarbons (HCFC’s) are fully or partly halogenated paraffin hydrocarbons that contain only carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivative of methane, ethane, and propane.They are also commonly known by the DuPont brand name Freon.. CFC Refrigerant: CFC refers to the chemical composition of the refrigerant. The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC-11. Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. Refrigerant Molecular Mass CFC-11 137.4 HCFC-123 153.0 HFC -245fa 134.0 5599 Refrigerant Molecular Mass CFC-12 120.9 CFC-500 99.3 HFC-134a 102.0 HFO-1234yf 114.0 R-12 Alternatives12 Alternatives 6600. HFOs are known as the fourth generation of refrigerants. Recognized as Ozone Depleting Potential (ODP) and Global Warming Potential (GWP), they represent a greener alternative to CFC and HCFC. Decades later, scientists would discover that chlorine, a component of CFC and HCFC refrigerants, is damaging to the ozone layer. The halons have ODPs ranging up to 10. Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon (CFC). The ODP of a chemical is the measure of how much it causes degradation of the ozone layer as compared to trichlorofluoromethane (CFC-11), which has a baseline ODP of 1.0. Hydrofluroolefin refrigerants, or HFOs, are the latest and greatest to come out to the refrigeration world. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. It is a colorless, faintly ethereal, and sweetish-smelling liquid that boils around room temperature. CFC-11 is a Class 1 ozone-depleting substance which damages Earth's protective stratospheric ozone layer. The U.S. EPA recently identified sales of a product marketed as Cool Penguin “F-12.” Sold in small cans through online retail platforms for motor vehicle air conditioner use, some cans of Cool Penguin consisted of CFC-12, CFC-114, HCFC-142b and HCFC-22, along with non-ozone depleting components. Freon Group Refrigerants Application and ODP Values Refrigerant Areas of Application ODP CFC 11(R11) CFC 12 ( R 12 ) CFC 13 (R 13) CFC113 ( R113 ) CFC114 ( R114 ) Blend of R22 and R115 (R502) Air-conditioning Systems ranging from 200 to 2000 tons in capacity. The mechanical vapor compression cycle utilizes the evaporation of a refrigerant to absorb the heat, which will lead to lower the temperature of the surrounding of the evaporator..
