Here we examine chlorodifluoromethane (HCFC-22), a chemical designated as toxic in 1994 by the U.S. Environmental Protection Agency's Toxics Release

HCFC-22. Air conditioning equipment generally runs most efficiently on the type of refrigerant it was designed for, but when the time does come to replace or retrofit your system, there are many non-ozone-depleting alternatives available. What Alternatives Can Be Used Instead of HCFC-22? Many non-ozone-depleting alternatives to HCFC-22 are

CFC-11, 5 mg/kg. CFC-12, 5 mg/kg. CFC-113, 5 mg/kg. HCFC-22, 5 mg/kg. HCFC-141b, 5 mg/kg.

The HCFC-22 phase-out is a part of the EPA’s HCFC phase-out schedule, which the United States agreed to in 1987 as part of the Montreal Protocol. HCFC-22 contributes to depletion of the ozone layer, and its production is scheduled to halt by 2020 in the United States. As HCFC-22 production is phased out, chloroform production is expected to decrease significantly. Many diverse industries have depended on Freon™ 22 (R-22) refrigerant as their go-to hydrochlorofluorocarbon (HCFC) cooling product for decades.

As HCFC-22 production is phased out, chloroform production is expected to decrease significantly. Many diverse industries have depended on Freon™ 22 (R-22) refrigerant as their go-to hydrochlorofluorocarbon (HCFC) cooling product for decades. It's been the most widely used choice for air conditioning (AC) and medium- to low-temperature commercial refrigeration because of its dependability—and because it works.

R-22 is the most widely used HCFC refrigerant for HVACR applications, such as residential air conditioning, refrigeration, and other cooling applications. Aug 23, 2019 It's important to note that the EPA uses the scientific term HCFC-22 to refer to refrigerant R-22 in its listings. Changes To Leak Rates In 2019. May 21, 2019 All HCFCs are “Class II” ozone-depleting substances (ODS) subject to the phase out per the Montreal Protocol and U.S. Clean Air Act. R22 Has HCFC-22 known as R-22 is used as a refrigerant for previously manufactured for AC Systems. R-22 is an ozone-depleting substance that will not be produced in Jul 17, 2019 One of those compounds was R-22, also known as Freon, a hydrochlorofluorocarbon (HCFC) that became the standard refrigerant for Since the 1930s, R-22 (also known as Freon or HCFC-22) has been used in refrigeration and air conditioning.

In an experimental study on residential air conditioner of 3.5 kW capacity using R161, it was 2012-09-08 · As government authorities in the industrialized world work to phase out an air-conditioner coolant, HCFC-22, a black market has sprung up for it. HCFC-22 costs are a tiny fraction of finished product costs and so do not materially affect the size of those markets. Consequently leakage, in terms of increased use of HCFC-22 due to lower costs, is not significant. Nor would there be any economic incentive for HCFC-22 plants to be constructed speculatively since, even if the product were given Chlorofluorocarbons: CFC-11, CFC-12, CFC-113, HCFC-21, HCFC-31, HCFC-133a .

HCFC-22 is used as a refrigerant in several different applications, as a blend component in foam blowing and as a chemical feedstock for manufacturing synthetic polymers.
