We are excited to announce that we have selected the first five Technology Case Studies to be presented at ATMOsphere America 2013. Below you will find a short summary of the selected case studies.
We are also pleased to announce that Baltimore Aircoil Company will be supporting us as a Silver Sponsor and that Hansen Technologies is our newest Bronze Sponsor.
Technology Case Studies – Part 1
IGA Cap-de-la-Madeleine, Carnot Refrigeration
Key words: Sobeys, supermarket, CO2 commercial refrigeration, heat recovery
To reduce its energy consumption and green house gas emissions, Sobeys Quebec chose to replace its existing HFC refrigeration system at its IGA Extra Supermarket in Cap-de-la-Madeleine with a CO2 refrigeration system from Carnot. This new system uses captured CO2 gas for water heating purposes without the need for a heat exchanger or pumping system. This case study will highlight how the new CO2 system helped the store achieve a 22% reduction in refrigeration energy consumption.
Low charge ammonia condensing units for the US market by Derek Hamilton, Star Refrigeration
Key words: Freezer, NH3 low charge, ‘plug and play’, industrial refrigeration
This case study focuses on a freezer installation in which a low charge ammonia package has offered lower installation costs, better efficiency, and lower operational costs than alternative HFC solutions. The presentation will show that the latest aluminum heat exchanger technology, developed and built in the U.S., coupled with the proven low pressure receiver system, can result in high efficiency ammonia systems with a minimal ammonia inventory.
Ammonia/CO2 system offers mainstream solution, Danfoss
Key words: Canadawide, distribution c./warehouse, NH3/CO2 industrial refrigeration
Together, Danfoss and Cimco Refrigeration present a unique ammonia/CO2 refrigeration solution recently deployed by Canadawide for an expansion at its 60,000 ft2 distribution center/warehouse operation in Montreal, Canada. The study addresses how the unique solution contributed to energy, installation cost, and maintenance savings for Canadawide. The presentation also shows how this solution is scalable for mainstream deployment.
Carbon Dioxide Heat Pump Field Study by Merle Rocke, EcoThermics Corporation
Key words: Country maid dairy, CO2 heat pump, transcritical, simoultaneous heating and cooling
The study presents a pioneering project between EcoThermics and Country Maid, utilizing transcritical carbon dioxide (CO2) dedicated heat recovery. The project involved the study of a prototype CO2 hydronic heat pump supplying simultaneous high temperature hot water and cold water for space air conditioning in a commercial/industrial food production facility under actual operating field conditions. This case study attempts to extrapolate comparisons to traditional methods and outline the lucrative market possibilities of CO2 heat pump technologies.
How to manage 150 gramms propane limit with big plug in appliances in US market by Doug Smith & Marek Zgliczynski, Embraco North America
Key words: R290 under 150g, hermetic compressors, light commercial refrigeration
In 2011, the EPA SNAP positive conclusion opened up an opportunity in the U.S. household and light commercial refrigeration applications for the use of hydrocarbons. However, the approved charge limit of 150g of propane creates a challenge for larger sized light commercial appliances. This case study presents different options for addressing this issue, including a comparative analysis.
Next week, we will announce the second round selection of Technology Case Studies for ATMOsphere America 2013.
