Air conditioning work must be performed using approved CFC recycling equipment that meets the standard of SAE J To verify that CFC recovery and recycling equipment meets this standard, see approved equipment list or contact the ETL Testing Laboratories at () and Underwriter’s Laboratory at () (back to top). The Company's products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, and include refrigerant and industrial gas sales, refrigerant management services consisting primarily of reclamation of refrigerants and RefrigerantSide® Services performed at a customer's site, consisting of.   CFC’s are chloro flouro carbons which are refrigerants that run inside an air conditioner or refrigerator. All refrigerants run in a closed circuit. CFC’s cannot leak unless there is a leakage in the refrigerant circuit. Moreover, nowadays CFC’s a. Code of Practice for Refrigeration and Air Conditioning. NOTICE ON THE DOCUMENT. This Code of Practice for Refrigeration and Air Conditioning was made possible using funding from the Multilateral Fund (MLF) through the World Bank (WB) and the Government of Sweden, granted to the Philippine Government through the Department of Environment and Natural Resources (DENR) as implementing 5/5(3).

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. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate. Hydrofluorocarbons (HFCs) also act to warm the planet. commonly used in air conditioning, process chiller and industrial refrigeration plant applications.’ R is a hydrochlorofluorocarbon (HCFC) and was commonly used in air conditioning, process chiller and industrial refrigeration plant applications. It will soon be phased out due to ozone depletion potential and status as a potent greenhouse gas.   The Montreal Protocol led to a global phase-out of most substances that deplete the ozone layer, such as chlorofluorocarbons (CFCs). A happy side-effect of . types of refrigeration and air conditioning, as solvents, insulating and blowing agents, and in a variety of other goods and man-ufacturing processes, CFCs have depleted the global ozone column by % to 3 % in the last eight years. As a consequence, the quantity of UV-B radiation over much of the earth's surface is % greater than.

The 40 CFR 82 Subpart F regulation applies to your facility if you recover refrigerant from appliances or other stationary sources such as air conditioners (not motor vehicle air conditioners) and refrigeration equipment before disposal/recycling. These regulations prohibit purposeful venting and minimize accidental releases of ozone-depleting refrigerant compounds (CFCs.

Mr. Coad passed away in August Harry J. Sauer, Jr., PhD, PE, Fellow ASHRAE, was a professor of mechanical and aerospace engineering at the University of Missouri-Rolla. He taught courses in air conditioning, refrigeration, environmental quality analysis and control, and related areas. Aerosol propellants and refrigeration devices often make use of chlorofluorocarbons and related compounds more commonly known as their trade name, Freon. Freon also acts and an organic solvent though it is a man-made compound. Although there are dozens of types of Freon, they all fall into CFC, HFC and HCFC.

Chlorofluorocarbon Uses in Army Facility Air-Conditioning and Refrigeration by Chang W. Sohn Kelly 0. Homan Benjamin J. Sliwinski Recent studies have verified that the emission of manmade chlorofluorocarbons (CFCs) into the atmos-phere has depleted ozone in the stratospheric layer, and may affect terrestrial ecology.

A special numbering system is to be used for fluorinated alkanes, prefixed with Freon- R- CFC- and HCFC- where the rightmost value indicates the number of fluorine atoms, the next value to the left is the number of hydrogen atoms plus 1, and the next value to the left is the number of carbon atoms less one (zeroes are not stated), and the remaining atoms are chlorine.

Most refrigerants found in air conditioners, refrigerators, and freezers contain fluorocarbons, and many fluorocarbon compounds contain chlorine. Chlorofluorocarbon (CFC) refrigerants were commonly used in equipment manufactured before Equipment manufactured before may use hydrochlorofluorocarbon (HCFC) refrigerant.

The most widely used CFC both in aerosol dispensers, such as spray cans and fire extinguishers, and in refrigeration devices, CFC is also set to be completely phased out.

Known in the automobile industry as R (Refrigerant), this chlorofluorocarbon was used extensively in automobile air conditioning systems prior to [Show full abstract] information for the Army's air-conditioning and refrigeration (AC and R) equipment inventory based on site studies of three Army installations and information in the Red.

Grether International Environmental Corporation, Oklahoma City, OKUSA This Paper deals with the ozone depletion and the chlorofluorocarbon (CFC) issues as they affect the air conditioning and refrigeration by: 2.

The term refrigeration means cooling a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature).

In other words, refrigeration is artificial (human-made) cooling. Energy in the form of heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir.

information for the Army's air-conditioning. In Augustthe U.S. Environmental Protection Agency issued final regulations that implement the Montreal Protocol on Substances that Deplete the Ozone Layer.

The regulations require a 50% reduction in consumption of fully halogenated chlorofluorocarbons (CFCs) within 10 years and a freeze on consumption of halons within 4 years.

Consider the climate and the vehicle’s type of duty. Repair and Recharge This is probably the best option while CFC is still avail-able at a reasonable price. During the next fifty years the applications expanded to include foam blowing, precision cleaning, air conditioning, refrigeration, and propellants for medicinal, cosmetic, food, and general-purpose aerosols.

These uses eventually resulted in large emissions of CFCs into the atmosphere. Refrigeration and air conditioning processes are now part of our way of life and it would be inconceivable for it to be any other way. They have become essential ingredients for maintaining and improving our quality of life.

The refrigeration cycle: The refrigerant absorbs the heat () as energy source to evaporate in the closed space (A). Among these, the chlorofluorocarbon (CFC) group and related bromofluorocarbons or halons have been identified as potentially the most dangerous (see Table ).

Refrigerants containing chlorine or bromine contribute to the breakdown of the ozone layer (see Figure ). The reaction is as follows: However, the CIO molecule is unstable.

It breaks down and reacts with ozone molecules (in accordance with the equation above) repeatedly until .air conditioning systems (APT A, ). Almost all buses use conventional mechanical' refrigeration (vapor compression [V /C]) systems. In a mechanical refrigeration system, a refrigerant fluid is maintained under pressure in a closed system consisting of a reservoir of liquid, an expander, an evaporator, a compressor, and a condenser (Figure 1).In the s, two significant new uses that greatly expanded production of CFCs were created.
