Choosing and Using Alternative Refrigerants for Motor Vehicle Air Conditioning Ozone Protection Hotline (800) 296-1996 February 2, 1999 Changes from the February 25, 1998 version: changed name of Free Zone manufacturer. YouTube. R134a performs similarly to R-12, making it an easy-to-use replacement, and is relatively safe to use as it has an ASHRAE classification of A1. The automotive industry relied on R-12, a common CFC-based refrigerant commonly called Freon, for many years. several alternative refrigerants considering a range of selection criteria that include: refrigerant engineering performance, system design impact, MAC system changes to optimize the use of new refrigerants, cost, flammability, and environmental impacts including global warming, and human toxicity risks. It has also gone through warm periods when … Comparison of Different Alternative Refrigerants to HCFC-22 B.HADYA 1, Dr. P. USHA SRI 2 . Due to the considerable existing economic investment in this equipment it is not expected that such equipment will be The Environmental Protection Agency (EPA) is responsible for implementing the R-22 refrigerant phase out for the United States. 428 J. Chem. This would take some time, but R-410A refrigerant, a hydrofluorocarbon compound (HFC), was soon considered to be the most common alternative to R-22. This natural ISObutane refrigerant gas doesn’t need to be recovered as it is hydrocarbon fluid. Most domestic refrigerators and freezers use CFC-11 as the blowing agent for the polyurethane foam which insulates and provides structural support for the appliance. Production of chlorofluorocarbon (CFC) refrigerants will stop permanently by the end of 1995, and air-conditioning and refrigeration (AC/R) systems will have to use alternatives to CFC. At the moment the effect is still small -- about 0.012 W/m 2 for all CFC substitutes combined. In this The CFC partial pressure is expressed in units of 10–12 atmospheres or parts-per-trillion (ppt). Data 2001, 46, 428-432 Thermal Conductivities of Alternatives to CFC-11 for Foam Insulation Richard Perkins,* Laurence Cusco, John Howley, Arno Laesecke, Sigrun Matthes, and Maria L. V. Ramires† NIST Physical and Chemical Properties Division, 325 Broadway, Boulder, Colorado 80305-3328 The present work examines the thermal … THE STORY OF "GREENFREEZE" In the spring of 1992 Greenpeace brought together scientists who had extensively researched the use of propane and butane as refrigerants, with an East German company DKK Scharfenstein. There are no hydrocarbons here instead MO99 is an HFC refrigerant. A blend that contains a CFC and any other product is still considered a CFC refrigerant. 428 J. Chem. reduced within a short time period. CFCs came to dominate first refrigeration and later HVAC because of their safety and efficiency. 11. However, they do not deplete the ozone layer. The paper outlines EPA's role in investigating alternatives to replace the chlorofluorocarbon CFC-114 (1,1,2,2-tetrafluorodichloroethane) as the refrigerant in retrofitted Navy shipboard chillers. Consulting Engineer Post Office Box 12014 Arlington, VA 22219-0014 USA for the Alternative Fluorocarbons Environmental Acceptability Study The West Tower, Suite 400 1333 H Street NW Washington, … with those of CFC-12 and HFC-R134a refrigerants. The U.S. Army`s AC/R systems have a total cooling capacity of more than 1 million tons; approximately 55 percent of these systems use CFC-based refrigerants. Texaco Heritage Plaza's Converted Chillers Type Size Old Refrigerant 3-stage centrifugal 1,050 tons each CFC-11 HCFC-123. “natural refrigerants”. The finest alternative for R-22 Freon is often R-407c. Alternative Refrigerants and Oils Q: What is the right oil to use with the new refrigerants? Earth’s climate has changed many times. EPA may place conditions or restrictions on how an alternative can be used. CFC-12 is used as the refrigerant. With the introduction of all of these new refrigerants the use of refrigeration and air-conditioning really began to pick up over the next twenty to thirty years. The selection of alternate refrigerants should not hamper the performance of the refrigeration system because it leads to fall in the demand of the refrigerant. List of HFC refrigerants: HFC refrigerant (hydrofluorocarbons) is the third generation of fluorinated refrigerants. well as alternative refrigerants that possess a lower GWP. They mostly break down before they reach the ozone. CFC is well-known as a contributor to ozone depletion. CFC Refrigerant Alternatives Energy efficiency/energy use differences are small between CFC baseline refrigerants and HCFC or HFC alternatives ( Fig. alternatives to existing chlorofluorocarbon (CFC) and hydro-chlorofluorocarbon (HCFC) refrigerants. Refrigerant types: CFC Refrigerant: CFC refers to the chemical composition of the refrigerant. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. A blend that contains a CFC and any other product is still considered a CFC Freon™ 123 refrigerant is a hydrochlorofluorocarbon (HCFC) replacement for the chlorofluorocarbon (CFC) R-11 in centrifugal chillers. The Environmental Protection Agency (EPA) is responsible for implementing the R-22 refrigerant phase out for the United States. HCFCs contain chlorine, fluorine, and carbon (just like CFC), but also contain a hydrogen atom which decreases their stability and gives them a shorter lifetime in the atmosphere. Controls on greenhouse gas emissions are necessary. There are no hydrocarbons here instead MO99 is an HFC refrigerant. We specialize in Parts for Daikin, Carrier Midea, Air-Con, Chigo, YMGI, Cooper & Hunter, OLMO. alternative refrigerant using separate recovery equipment dedicated to that refrigerant. It has been used in refrigeration systems since 1840 and in vapor compression since 1860. It is a hydrocarbon with less harmful fluorocarbon than other alternative refrigerant gases. Figure 1 Map of Refrigerant Change. Furthermore, its ODP and GWP are 0. Background Scientists worldwide have concluded that CFC-12 and other chlorofluorocarbons deplete the ozone layer. If a system has R22 in it already you can’t use a alternative refrigerant to easily add to the R22. Figure1 shows how the use of refrigerants is evolving. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22. Record ID : 1997-3199 Languages: English Subject: Figures, economy Source: International Conference on Ozone Protection Technologies.Conference proceedings. Alternative to Refrigerant for Industrial Cooling. Compared to CO2, the three CFC alternatives have a greater greenhouse effect. Table 3 summarizes typical data for both Freon™ 134a and CFC-12. 1.5 ). If a system has R22 in it already you can’t use a alternative refrigerant to easily add to the R22. The best replacement for R-22 Freon is usually R-407c. While many automotive manufacturers are using R-1234yf in new vehicles, German brands like Volkswagen, Porsche, Audi, and BMW have committed to R-744 as their refrigerant of choice. THR02 is proved to be an environment-friendly, nontoxic, inflammable, drop-in alternative to CFC-12 and HFC-134a. MO99 offers the consumer and HVAC tech a lower cost alternative. The CFC refrigerants fulfilled all the primary requirements and heralded an unprecedented revolution in the refrigeration and air-conditioning industry (Bhatti, 1999). Details. HFCs are the newest alternative refrigerants. The best part about this alternative R-22 is that it is safe! Benefits of using Freon™ 123 include: Low ozone depletion and excellent environmental properties This option has the highest initial cost, but in many cases may be the cheapest Alternative Refrigerant. smooth transition to alternatives that pose lower overall risk to human health . Since Freon is a CFC (chlorofluorocarbons), it has been phased out in lieu of more environment-friendly refrigerants because of its capability to damage the ozone layer. In the 1970s, environmental concerns came into play. For example, using a motor vehicle A/C refrigerant accepted under SNAP as a CFC-12 substitute requires, among other things, the use of a new label and new fittings unique to the alternative, and the CFC-12 must first be removed from the system. “For example, R-134a survives 14 years compared to R-1233zd (E), one of the new alternative refrigerants, at only 29 days,” explains Vijay Deshmukh, centrifugal chiller portfolio leader at Trane. Production of chlorofluorocarbon (CFC) refrigerants will stop permanently by the end of 1995, and air-conditioning and refrigeration (AC/R) systems will have to use alternatives to CFC. EPA’s Significant New Alternatives Policy (SNAP) Program ensures the . Boorneni and Satyanarayana [7] have been focused on alternative refrigerant to conventional CFC refrigerant, CFC like R-12, R- 22, R-134a are not eco-friendly. Measuring the alternative refrigerantssolution requires: generating a total addressable market forecast of HFC refrigerant gas emissions for the period 2020–2050 (in kilotons of carbon dioxide-equivalent emissions per year), forecasting an adoption of replacement refrigerants and the resulting decreased emissions from reducing the amount of HFC produces, used, and released i… This also involved a closer examination of the use of R152a. Every human being or a machine has a value. Out with R-22, In with R-410A . There are cars on the road today using this alternative. ... R152a refrigerant found as a drop in replacement for R134a in vapour compression system. Publication date: 1996/10/21 Document available for consultation in the library of the IIR headquarters only. Drop in solution Compatible with copper Miscible with mineral oil A third of original charge only is required when replacing halocarbons refrigerant in existing equipment Energy saving : up to 20% due to lower molecular mass and vapour … HFC’s are definitely not a good option for the replacement of CFC’s and HCFC’s The best choices from an environmental point of view are the natural refrigerants: Ammonia Hydrocarbons Carbon dioxide : Mainly for Vehicle AC and mobile refrigeration 19. A new long-term drop-in mixture alternative THR02 is developed and evaluated in a series of theoretical and experimental evaluations. Hydrocarbon Refrigerants Used since the 1880’s Zero ODP and negligible GWP Good substitutes for CFC’s, HCFC’s, and HFC’s. For this paper, the ones considered are R-22, R-152a, blends (or near azeotropes), and nonazeotrope refrigerant mixtures CNARMsl. Refrigerant HFCs can last up to 270 years in the atmosphere, according to EPA. On Monday, May 3, the EPA officially proposed to phase out HFCs, as per HuffPost, lowering their use and production by 85 percent over the next 15 years. Global warming is often described as the most recent example of climate change. Commercial CFC production began with R-12 in early 1931, R-11 in 1932, R-114 in 1933, and R-113 in 1934; the first hydrochlorofluorocarbon (HCFC) refrigerant, R-22, was produced in 1936. - Early published test data indicate small penalties for substitutes, but recent industry data show near equal refrigerant performance as achievable Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. To replace a card, fill out and submit an application for a Replacement CFC Card. Once received by our office, you should receive your replacement card in 7-10 days. You know… the refrigerants we deal with on a daily basis such as R-134a, R-404A, and R-410A. Ozone-Depleting Substances: Alternatives.

ASHRAE # Trade Name Manufacturer (a)Replaces Type (e) TypicalLubricant. CFC-11 was assigned an ODP of 1.0; all other chemicals have an ODP relative to that of CFC-11. cylinder and R-744 costs $68 to fill a 100 lb. Abstract--The main objective of this paper is to explore the possibility for developing new zero ODP (Ozone Depletion Potential) and low GWP (Global Warming potential) Alternate Refrigerants to R-22 in air conditioning application. A large set of CFC-236ea operating data, as well as limited number of CFC-114 data, were available for this study. Alternatives and safety groups Natural refrigerants HFCs with lower GWP, such as R32 Hydrofluoroolefins (HFOs) HFC-HFO blends. The finest alternative for R-22 Freon is often R-407c. The report gives results of an investigation of the operation of a centrifugal compressor--part of a chlorofluorocarbon (CFC)-114 chiller installation--with the new refrigerant hydrofluorocarbon (HFC)-236ea, a proposed alternative to CFC-114. Economic impact of the alternative refrigerants against cfc refrigerants. well as alternative refrigerants that possess a lower GWP. -------f HCFC-123 was the obvious re- placement refrigerant because it is the only alternative to CFC-11 for low- pressure centrifugal chillers. But R-22 was not the first refrigerant to use the trademarked brand. The present commercially available HFC is HFC-134a. Applications Comments GWP* R-404A 125/143a/134a (44%/52%/4%) Genetron ® 404A Suva ® HP62 Forane ® 404A Honeywell DuPont Arkema HFCs: The CFC Alternative. This section will be the comparative analysis between the two refrigerant gases. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22. Recognized as Ozone Depleting Potential (ODP) and Global Warming Potential (GWP), they represent a greener alternative to CFC and HCFC. FluorocarbonsMedia. By 1963, these five products accounted for 98 percent of the total production of the organic fluorine industry. The R22 refrigerant which is used as an alternative to CFC-included refrigerants, has got a low ODP value and thus, its use is permitted until the year 2030. HCFCs then became the go-to refrigerants as alternatives to banned CFCs. requirements in addition to the earlier . It has a really low loss in capability (0 – 5%) relative to R-22 and is cheaper than many different R-22 alternative refrigerants. Production of chlorofluorocarbon (CFC) refrigerants will stop permanently by the end of 1995, and air-conditioning and refrigeration (AC/R) systems will have to use alternatives to CFC. The rule, called the American Innovation and Manufacturing (AIM) Act promises an uptick in the production of alternative refrigerants. There were numerous CFC refrigerants used during this time including R-11, R-12, and in 1935 a new HCFC refrigerant known as R-22.
