The saturated liquid viscosity o f ammonia ( NH3) and of the hydrotluorocarbons, ditluoromethane (CH2F2, R32) and 1,1,1,2-tetrafluoroethane (CF3-CH2F, R134a), was measured in a sealed gravitational viscometer with a straight vertical capillary. Ammonia’s fire hazard rating is usually stated as “slight” as it is only explosive in air at concentrations of Ahmed S. Fall 08 3 This Activity received funding from the Department of Industry as part of the Energy Efficiency Information Grants Program. The same figure for the ammonia plant was 11,695 kWh, i.e. The IPLV efficiency is 12 percent higher in an ammonia chiller. It’s no surprise one of the blog’s most popular posts is Ammonia As a Refrigerant: Pros and Cons.. Since ammonia is environmentally benign, having zero (GWP) and zero (ODP) characteristics, ammonia is emerging as one of the primary natural refrigerants of choice. It is also much lighter than air. 4,945 kWh less – 30%! Summary – Ammonia vs Ammonium. Cold Chain Containers Soluciones móviles. All of the hazards associated with ammonia are announced loudly by its pungent odor; and that odor is so strong that even at very low non hazardous concentrations, it repels people from a contaminated area. R134A VERSUS AMMONIA ? If ammonia gas escapes from a refrigeration system or a storage container, it tends to collect in high areas or ceilings. ...

Ammonia is not a universal refrigerant, and mainly suitable for industrial and heavy commercial applications. Included in an information pack is a document that analyses the main advantages and disadvantages of the most widely used refrigerants in cold stores and food processing, namely R404A and R717 (NH3, ammonia), when employed in mechanical … March 1, 2013 By Mathieu Courchesne, ing., Dessau. Ammonia’s toxicity, flammability and material compatibility have to be taken in to account. From a pure theoretical standpoint, CO2 is slightly less efficient than ammonia, but this difference decreases as the evaporator temperature drops. First cost of the ammonia chiller is twice that of an R-134a chiller. Ammonia vs Freon - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Ammonia is ignitable when the concentration reaches 11 ~ 14%. While ammonia is imported too, it can also be sourced locally. Industrial chillers for the supply of chilled water, cold glycol or brine, are frequently used over a long time, and have become even more attractive for several applications to replace direct refrigeration systems. The combined temperature range was from 250 to 350 K. The Freon is a tradename while refrigerant is the name of a group of compounds used in heat pump cycles and refrigeration cycles. Air-conditioning is widely used in the industrial market in various applications and we are at the fore front of the game. This article was corrected on February 26, 2013. All of the hazards associated with ammonia are announced loudly by its pungent odor; and that odor is so strong that even at very low non hazardous concentrations, it repels people from a contaminated area. Ammonia Refrigeration HVAC. > > >Why don't you see it in more applications? Freon is colorless, odorless, non-flammable, non-explosive, and with chemical stability. In brief, ammonium is the major cation that originates from ammonia. But because CO2 is a very dense gas, the size of the equipment needed to provide the … Freon vs Ammonia & Glycol Refrigeration. Toxic and fire dangerous. This article was corrected on February 26, 2013. At the same time, there is a huge global population of ammonia systems where those challenges are successfully dealt with. Ammonia vs Freon. Ammonia is a product that falls within WHMIS/GHS legislation. Although neither ammonia nor freon is an ideal refrigerant , there are advantages and disadvantages to both types. Ammonia is a natural refrigerant that has been used for many years in a variety of applications due to its high thermal efficiency. Ammonia vs Freon refrigeration systems - comparison July 2016 With a major move towards natural refrigerants coming into effect around the world we at Lutz Refrigeration see the trend for the future moving towards Ammonia for large scale cold storage and gradually towards the medium sized and eventually smaller rooms. Ammonia in water solution is called aqua ammonia or ammonium hydroxide. 14-4-2016 2 Overview : R134a versus ammonia • Short presentation of Johnson Controls • Intro in ecodesign • F-gas : York’s point of view The “Ammonia vs. Freon” debate is not a symmetrical one; the pressure is against ammonia, and for its replacement by halocarbon refrigerants. Ammonia Vs Freon [2nv801m83ylk]. CO2 efficiency vs. ammonia efficiency. Ammonia and R-134a chillers have almost the same efficiency at 100 percent and 75 percent capacity. Freon_vs_Ammonia_and_Glycol_Refrigeratio.docx - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free. 6. Freons are also less dense than ammonia, requiring up to double the weight to reach the same volume in litres. The key difference between ammonia and ammonium is that ammonia is an uncharged but polar molecule existing as a gas at room temperature, whereas ammonium ions are charged and exist as free ions in solution or as crystallized salt compounds. Ammonia is used in the big refrigerating productions > > > >How dangerous is Ammonia? They showed, that for the Freon systems, the average monthly electricity consumption had been 16,640 kWh per 1,000 tons of storage capacity. A key characteristic of creating an industrial refrigeration system is the refrigerant of choice. Sorry for my bad English. Only iron, steel, certain rubbers and plastics, and specific nonferrous alloys resistant to ammonia should be used for fabrications of anhydrous ammonia containers, fittings, and piping. AMMONIA (R717) Used as a refrigerant for over 30 years, ammonia was gradually being replaced by chlorofluorocarbons (CFCs), but has begun regaining some ground since the adoption of the Montreal Protocol and the Kyoto Protocol, aimed at completely banishing HCFCs … I`m from Russia, Moscow. T y p e ASHRAE Number IUPAC Chemical Name Molecular Formula CAS registry number/ Blend Name Atmospheric Lifetime (years) Semi-Empirical ODP net GWP 100-yr OEL/PEL ppm (v/v) & Ammonia is more efficient as a refrigerant, you simply need to look at a Refrigerant Tables & Charts to see that ammonia has a higher latent capability per pound compared to the same pound of freon. Ammonia, especially in the presence of moisture, reacts with and corrodes copper, zinc, and many alloys. Refrigerants: Ammonia vs CO2.

Examples for Freon include chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) while examples for refrigerants are ammonia, sulfur dioxide, carbon dioxide, etc. The ammonia chiller has a much better part-load efficiency. Noise and Vibration The noise and vibration of Ammonia system is relatively larger as normally it's used for large system. Yes, dangerous. : +52 (667) 721 - 5105 mario@thermovil.com The first CFCs were synthesized by Frédéric Swarts in the 1890s. No, just ammonia is not very expansive. The packaged ice industry uses two main types of refrigerants, Freon and Ammonia for ice manufacturing equipment. TERMS & CONDITIONS. CO2 is slightly less efficient than ammonia but this difference is less noticeable at lower temperatures. The term "freon" is also a generic descriptor of a fluorocarbon refrigerant. In the late 1920s, a research team was formed by Charles Franklin Kettering in General Motors to find a replacement for the dangerous refrigerants then in use, such as ammonia. When the concentration reaches 16 ~ 25%, ammonia is explosible. The "Ammonia vs. Freon" debate is not a symmetrical one; the pressure is against ammonia, and for its replacement by halocarbon refrigerants. End-users are often faced with a dilemma when they have to choose between refrigeration contractors, especially if there is an option between Freon and Ammonia. Several publications have been made available as part of the ‘Improving Cold Storage Equipment in Europe’ (ICE-E) project deliverables. Freon types are priced differently, but you are looking at an average of R120per kg.
