Jim Armer - Planning & performance - natural refrigeration system design
PDF document
published on 18 June 2014
Jim Armer highlights the key roles both preparedness and stakeholder engagement play in managing the risks and associated costs linked to the installation and maintenance of new systems. The sharing of information and good planning are vital in installing and maintaining successful natural refrigerant systems.

Xavier Marle - Mechanical sub-cooling - no climatic limit to transcritical applications
PDF document
published on 18 June 2014
From Systemes LMP, Xavier Marle talks about the advantages of mechanical sub-cooling in improving the efficiency of CO2 transcritical refrigeration. According to Marle, mechanical sub-cooling can reduce energy consumption by 17%, improve the Energy Efficiency Rating (EER) by 35%, and decrease the number of refrigeration compressors needed to keep systems in a positive temperature mode.

Andre Patenaude - First North America built Copeland CO2 booster transcritical rack
PDF document
published on 18 June 2014
Andre Patenaude Director from Emerson presents a Life Cycle Climate Performance (LCCP) comparison of a CO2 booster system and an R404A DX system. The CO2 transcritical booster system has a 64.5% lower carbon footprint at 70°F (21°C) than the R40RA DX system.

Louis Morris - The importance of taking a systems approach to CO2 installations
PDF document
published on 18 June 2014
Louis Morris, from Micro Thermo Technologies a subsidiary of the Parker Hannifin Corporation presents the company's focus on providing a holistic, system approach that ensures none of a retailer's HVAC heating and cooling systems are competing with each other. To illustrate this approach Morris describes the way in which all of the subsystems in an IGA store in Terrebonee, Québec, Canada are interconnected, so that the condensers, RTU (rooftop units), lighting, racks and cases influence each other.

Tom Wolgamot, Dan O'Brien - A case study of the CO2 system at Whole Foods Market, Castro
PDF document
published on 18 June 2014
In a joint presentation Dan O-Brian from Zero Zone and Tom Wolgamot from DC Engineering present on the advantages of CO2 systems versus HFC DX systems. They compare three similar sized Whole Foods stores, one with a CO2/R407A system, one with a DX LT/Glycol system, and one with a distributed system.

Michael Englebright - Fast track and implementation of transcritical CO2 refrigeration into Roche estate
PDF document
published on 18 June 2014
Michael Englebright from Carel focuses his presentation on small footprint CO2 units developed on the basis of traditional condensing units, a technology already used in Japan. In the US, Roche pharmaceuticals has already invested in this technology, and by the end of 2014, Englebright says that 18 such systems are planned for completion.

Jeff Newel - CO2 supermarket system - case study of a warm climate CO2 booster system
PDF document
published on 18 June 2014
Jeff Newel from Hillphoenix, presents an industry first, the company’s pioneering installation of a CO2 booster system in a warm ambient climate at a Sprouts Farmers Market store in Dunwoody Georgia. Here, a standard Advansor CO2 booster system with 4 MT compressors and 3 LT compressors was installed together with an adiabatic gas cooler, minimising the CO2 temperature leaving the gas cooler and thereby reducing energy consumption by 6%.
