2nd round of case study selections for ATMOsphere America 2014

[-] text [+]

We are pleased to announce the following technology case studies that have been selected for the Commercial Refrigeration Session at ATMOsphere America 2014. The event will take place from 18 – 19 June in San Francisco, California.

The effects of mechanical sub cooling and its benefits by Jeffrey Gingras, Systemes LMP

The case study demonstrates that mechanical sub cooling increases the quality of the refrigerant prior to the expansion valve. This methodology helps Systemes LMP in achieving a higher percentage of liquid than flash gas and increases the refrigeration capacity as well as the Energy Efficiency Ratio. When using mechanical sub cooling one will be able to obtain 21% more efficiency and consume less energy than a conventional synthetic system in warmer climates. This is strictly based on Power consumption.

The importance of taking a systems approach to CO2 installations - recent experiences with Sobeys in North America by Louis Morris, Parker

This paper will review Parker/Micro Thermo Technologies' experience with the CO2 refrigeration installation at the IGA Terrebonne (Quebec) supermarket. When Sobeys decided to use CO2 for the refrigeration in all its new stores several years ago, Micro Thermo Technologies adapted and developed new control components to support Sobeys' efforts. The results of these efforts in terms of energy usage and overall control improvements will be reviewed in this case study, along with best practices and lessons learned.

A case study of the CO2 system at Whole Foods Market, Castro by Tom D. Wolgamot, DC Engineering, Tristam Coffin, Whole Foods Market and Dan O'Brien, Zero Zone

This case study examines the successful application of a partnership approach to the design, installation, and operation of the CO2/407A cascade refrigeration system in the Whole Foods in the Castro district of San Francisco. Long-term partners worked collaboratively to deliver a system that met Whole Foods sustainable criteria for equipment costs, installation costs, and energy costs. This case study will review the expectations set forth by Whole Foods and the overall project delivery method that lead to a successful project. Comparative system costs will be reviewed as a mean of demonstrating the positive results. Lessons that were learned will also be discussed so that others may successfully deploy CO2 systems in the North American market.

About ATMOsphere America 2014
18-19 June at The Westin Market Street in San Francisco, California

For its third annual event, ATMOsphere America 2014 is shaking things up and moving to the West Coast. Around 250 HVAC&R industry experts are expected to gather to discuss the latest developments in the natural refrigerant market. Presentations, panel discussions and technology case studies will focus on a range of topics from commercial, light commercial & industrial refrigeration to air conditioning, heat pumps, HVAC and more. An exciting new feature of this year’s event is an optional Napa Valley Wine Tour combined with a site visit, as well as an innovative session featuring utility providers.
