They are in line with the soon to be finalised corresponding standards in Europe that are currently being reviewed in order to accommodate for the increased interest in transcritical CO2 refrigeration in the region. The aligned standards establish common guidelines worldwide and will enable manufacturers to compare compressor behaviour and performance on a fair, “apple to apple” basis. US, Europe and China work together to develop common standards Titled ‘2012 Standards for Performance Rating of Positive Displacement Carbon Dioxide Refrigerant Compressors and Compressor Units’, AHRI developed Standards 571 (SI) and 570 (I-P) in cooperation with the Association of European Refrigeration Component Manufacturers (ASERCOM) and the China Refrigeration and Air-Conditioning Industry Association (CRAA), with a view to harmonising the rating conditions with CO2 standards under development in Europe and China. The AHRI standards, which concern CO2 compressors for subcritical and transcritical refrigeration applications, provide for the first time a rating method for compressors and compressor units that use CO2 as a refrigerant in the US. In Europe, the main compressor standards, namely EN1 2900 (Refrigerant compressors: Rating conditions, tolerances and presentation of manufacturer's performance data) and EN 13771-1 (Compressor and condensing units for refrigeration: Performance testing and test methods) are currently being revised to accommodate for the increased interest in transcritical CO2 refrigeration in the region. Under the umbrella of ASERCOM, CO2 compressor manufacturers Dorin and Bitzer have been leading this work to establish the European guidelines. In scope of AHRI standard: refrigeration only The new AHRI standards apply to electric motor driven, single and variable capacity, single and two stage positive displacement refrigerant compressors and compressor units operating with carbon dioxide in both subcritical and transcritical applications for refrigeration. The standards do not apply to carbon dioxide compressors used in other applications such as heat pumps and air-conditioning, automotive air-conditioners or household refrigerators and freezers, etc. Rating conditions According to the AHRI standards, data should be reported at the following conditions for the compressor or compressor unit application usage intended: Medium Temperature (e.g. fresh food display cases) Suction dew point temperature, -4 °F to 32 °F (-20 °C to 0 °C) Discharge dew point temperature for subcritical compression cycle, 32 °F to 77 °F (0 °C to 25 °C) or discharge pressure for transcritical compression cycle, 1160 psia to 1595 psia (80 bar to 110 bar) Useful superheat of 18 °F (10 K) for all operating points For subcritical applications, condenser exit subcooling of 0 °F (0 K) For transcritical applications, gas cooler exit temperature of 95 °F (35 °C) Refrigerating Capacity may include increased refrigeration effect provided by the subcooler per rating methods of section 5.5 of the standard Low Temperature (e.g. freezer cases) Suction dew point temperature, -58 °F to 14 °F (-50 °C to -10 °C) Discharge dew point temperature for subcritical compression cycle, 32 °F to 77 °F (0 °C to 25 °C), or discharge pressure for transcritical compression cycle, 1160 psia to 1595 psia (80 bar to 110 bar) Useful superheat of 18 °F (10 K) for all operating points For subcritical applications, condenser exit subcooling of 0 °F (0 K) For transcritical applications, gas cooler exit temperature of 95 °F (35 °C) Refrigerating Capacity may include increased refrigeration effect provided by the subcooler per rating methods of section 5.5 of the standard About AHRI, ASERCOM and CRAA Based in the US, AHRI is one of the largest trade associations in the nation, representing more than 300 heating, water heating, ventilation, air-conditioning and commercial refrigeration manufacturers within the global HVAC&R industry. ASERCOM is the Association of European Refrigeration Component Manufacturers, which among other issues elaborates safety and technical standards and promotes harmonisation of component standards and regulations. Similarly, China Refrigeration and Air-Conditioning Industry Association (CRAA) also promotes standards harmonisation by international cooperation and works to improve the standardisation system for Chinese refrigeration and air-conditioning industry. © 2012 R744.com - Managed by shecco™ Print this page | Close window Coca-Cola Brazil displays 100 CO2 coolers at Rio +20 20 June 2012 Coca-Cola Brazil, an official sponsor for Rio+20, is displaying 100 new R744 coolers provided by Metalfrio Solutions at several different conference locations. Rio +20 takes place from 20-22 June 2012 in Rio de Janeiro, Brazil. Underscoring the main focus of the United Nations Conference on Sustainable Development, Rio +20, Coca-Cola Brazil is showcasing 100 coolers using the natural working fluid R744. Supplied by the commercial refrigeration company Metalfrio, apart from the benign environmental impact of using of CO2 as a cooling gas, the VB43R coolers incorporate new energy efficiency standards and a longer component lifespan. Referring to the price of these coolers, Mr Adilson Lemos, Metalfrio Marketing Manager said: “In comparison, the cost of the eco-friendly coolers is still more expensive today than our other models, however as demand for the new units increases, production costs will decrease which will result in reduced pricing to the customer”. HFC-free by 2015 with CO2 coolers As part of the global strategy, Coca-Cola Brazil is gradually replacing their coolers with HFC-free equipment and from 2015 all new coolers will use CO2 gas in their compressors. According to the Sustainability report 2010/2011 published at the beginning of 2012, the Coca-Cola Company had by the end of August 2011 400,000 coolers using HFC-free refrigerants, including carbon dioxide and hydrocarbons. As mentioned at the ATMOsphere America 2012 conference on 13 June, so far Coca-Cola has placed around 612,000 HFC-free natural refrigerant machines, out of which more than 202,000 units use R744. It is expected that more than 650,000 HFC-free machines will be installed. With more than 10 million dispensers, vending machines and coolers in the global market, the Coca-Cola Company aims to reduce their impact on climate change through installing cooling equipment that is HFC-free. The Company’s phase out of HFCs, is expected to avoid emissions of more than 52.5 million metric tons of CO2 equivalent over the life of the equipment. Coca-Cola & Metalfrio - long-term partnership

  • Carrier Transicold to Highlight Sustainability Solutions at IAA Show 2016 Stand E15, Hall 27, IAA Show, Hanover, Germany, 22 – 29 September 2016
    For Immediate Release Contact: Andy Hemphill / Beth Laws For Carrier Transicold 020 8647 4467 [email protected] [email protected] Carrier Transicold to Highlight Sustainability Solutions at IAA Show 2016 Stand E15, Hall 27, IAA Show, Hanover, Germany, 22 – 29 September 2016 WARRINGTON, England, Aug. 25, 2016 — Carrier Transicold will introduce visitors to a prototype natural refrigerant trailer unit as well as a new generation of engineless transport refrigeration systems at the 2016 IAA Show in Hanover, Germany. Both technologies highlight Carrier’s commitment to helping fleets meet efficiency and sustainability goals. Carrier Transicold, which operates in the UK as Carrier Transicold UK, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX). The prototype natural refrigerant trailer unit will be making its IAA debut, mounted to a Rohr trailer and displayed on the Rohr stand (F09) in Hall 27. Following the IAA Show, it will enter service on a three-year technology field trial with German retailer Netto Marken-Discount. The prototype unit stands apart from conventional transport refrigeration technology for operating exclusively with carbon dioxide (CO2) refrigerant in a closed- loop system. CO2 is a safe and non-ozone depleting gas with a global warming potential (GWP) of one, delivering a massive reduction in F-Gases and making it the baseline against which other refrigerants are measured. Carrier Transicold will also showcase the new engineless transport refrigeration units that have joined its range following the strategic acquisition of Dutch firm, TRS Transportkoeling b.v. (TRS). The Carrier stand will feature an example of the ground- breaking ECO-DRIVE power module, which utilises the power generated by a truck’s own Euro VI diesel engine to drive a host refrigeration unit, removing the need for a secondary engine.

Is Earth’s ozone layer still at risk? 5 questions answered Editor’s note: Curbing damage to Earth’s protective ozone layer is widely viewed as one of the most important successes of the modern environmental era. Earlier this year, however, a study reported that ozone concentrations in the lower level of the stratosphere had been falling since the late 1990s – even though the Montreal Protocol, a global treaty to phase out ozone-depleting chemicals, had been in effect since 1989. This raised questions about whether and how human activities could still be damaging the ozone layer. Atmospheric chemist A.R. Ravishankara, who co-chaired a United Nations/World Meteorological Organization Scientific Assessment panel on stratospheric ozone from 2007 to 2015, provides perspective. What’s the prevailing view among atmospheric scientists today about the state of the ozone layer? The overall picture is clear: The Montreal Protocol reduced use of ozone-depleting chemicals and will lead to healing of the ozone layer.

  • QUANTIFYING the SOCIAL IMPACT of REFRIGERANT CHOICES the Role of Refrigerants in Climate Change… and What You Can Do About It
    QUANTIFYING THE SOCIAL IMPACT OF REFRIGERANT CHOICES The role of refrigerants in climate change… and what you can do about it AUGUST 2020 Contents The Impact of Refrigerants 4 The Importance of 2024 in California 5 The Social Cost of Carbon 7 What can HVAC Engineers & Chiller Manufacturers Do? 8 Natural & Alternative Refrigerants 9 Putting this into Practice with Two Case Studies 10 Case Study 1: Natural Ventilation 11 Case Study 2: Alternative Refrigerants 12 Global Leaders 13 Call to Action 14 Manufacturer Advocacy Letter 15 Contributors & References 17 iii QUANTIFYING THE SOCIAL IMPACT OF REFRIGERANT CHOICES The Impact of Refrigerants Refrigerants are significant contributors to climate change. Project Drawdown identifies refrigerants as the #1 most impactful factor in the construction industry (Project Drawdown, n.d.). Flourinated gases comprise 3% of the total greenhouse gas emissions in the United States, 92% of which are due to refrigerants in buildings and vehicles (Environmental Protection Agency, 2020). The impacts of refrigerants are classified using two measurements: ozone depletion potential (ODP) and global warming potential (GWP). Beyond the environmental impact, refrigerants additionally pose a risk to human health via risks of toxicity, flammability, asphyxiation and other hazards (Advent Air, 2015). Many of these risks can be mitigated via prudent refrigerant management, such as prevention of leakage and proper disposal. The Montreal Protocol In order to combat the harmful impacts of refrigerants, the 1987 Montreal Protocol was established to protect the ozone layer through phasing out the usage of refrigerants with high ODPs, including Chloroflourocarbons (CFCs) and Hydrochrloroflourocarbons (HCFCs) (U.S. Department of State, 2019).

  • Interpreting Environmental Impacts Resulting from Fruit Cultivation in a Business Innovation Perspective
    sustainability Article Interpreting Environmental Impacts Resulting from Fruit Cultivation in a Business Innovation Perspective Marco Medici * , Maurizio Canavari and Moreno Toselli Department of Agricultural and Food Sciences, Alma Mater Studiorum-University of Bologna, 40127 Bologna, Italy; [email protected] (M.C.); [email protected] (M.T.) * Correspondence: [email protected] Received: 29 September 2020; Accepted: 20 November 2020; Published: 24 November 2020 Abstract: Sustainability of food production is a major concern today. This study assessed the environmental impact of fruit production and discussed business implications for sustainability. Data were collected from three agricultural enterprises growing six species of fruit, extending over a total of 34 hectares, and producing roughly one thousand tons of fruit per year. The results of the life-cycle assessment (LCA) showed that several production activities heavily impact the environment: in descending order of absolute terms, fruit refrigeration, agronomic operations, irrigation, and fertilizer use were recognized as the most impacting. Other activities, including agrochemical applications, planting, and plastic use for harvesting and packaging, showed overall lower impacts. The high environmental impact associated with most of the production activities emphasizes the need to make the primary food production cleaner, more resource-efficient, and less energy-intensive. Affordable incremental innovations able to reshape the way business is conducted in the context of primary food production are proposed, mainly relying on process rationalization and digital switchover. The analysis of the business path toward increased sustainability involves strategic issues, ranging from the reshaping of production processes to relationships with consumers, affecting value proposition, creation, and capture. Keywords: business models; innovation; resource efficiency; sustainability; environmental assessment; fruit production; cleaner production; life cycle assessment (LCA); carbon footprint 1.

  • Ammonia – a Natural Refrigerant
    Ammonia – A Natural Refrigerant Environmentally friendly, economically efficient Our developed society depends on industrially produced refrigeration. Whether at home, in the production and storage of foodstuffs like frozen foods, yogurt and coffee, as part of industrial production processes in the automotive and chemicals/pharmaceuticals industry, or in air-conditioning systems – refrigeration is a central element everywhere. Industrially produced refrigeration is what makes a modern lifestyle possible. And natural refrigerants such as ammonia, carbon dioxide and hydrocarbons are an integral element in refrigeration. Natural refrigerants have been used to produce cold energy – mainly in food production and th storage – since the mid-19 century. Ammonia (NH 3) in particular has proven its worth in industrial refrigeration for over 120 years. Although “safety refrigerants“ – such as the now illegal CFCs – were increasingly used in plants built in the 1950s and ‘60s, ammonia has always managed to prevail in industrial refrigeration technology. Due in great part to the environmental debate surrounding ozone depletion and global warming, ammonia’s share in the market for refrigeration technology is on the rise again, and companies of long-standing tradition and experience prefer to work with ammonia. Compelling Characteristics Ammonia is a colourless gas that liquefies under pressure and has a pungent odour. In refrigeration technology, ammonia is known as R 717 (R = Refrigerant). Although it is synthetically produced for use in refrigeration, ammonia is considered a natural refrigerant because it occurs in nature’s material cycles. Ammonia has no ozone depletion potential (ODP = 0) and no direct greenhouse effect (GWP = 0). Its indirect greenhouse effect contribution is also very limited due to its high energy efficiency.
