Maho Ito, Ken Eklund - CO2 heat pump water heater field test
PDF document
published on 19 June 2014
Maho Ito of Sanden International USA and Ken Eklund, Washington State University Energy Program laboratory, presents test results of CO2 heat pump water heaters. Laboratory tests have shown an Energy Factor (EF) of 3.35 and Coefficient of Performance (COP) of 4.2 at outside ambient temperature of 67°F(19.4°C), compared to average electric resistance water heater of less than 1.0 EF. Field tests at four single-family homes in North Pacific States are currently ongoing, with results so far indicating a field performance very similar to that predicted from the lab test results.

Troy Davis - Introduction of Mayekawa's ECO Cute water source hot water heat pump at Torres De Alba Hotel
PDF document
published on 19 June 2014
The presentation by Troy Davis, Mayekawa USA MYCOM, discusses the introduction of Mayekawa's ECO Cute water source hot water heat pump at Torres De Alba Hotel in Panama City. The hotel owner recently installed the first ever integrated CO2 refrigerant water source heat pump heating and cooling system implemented in a hotel in Central America. By combining the hot water heating system with the chilled water cooling system using the Mayekawa water source heat pump unit, a higher COP is realised versus individual systems. This integrated system has been in operation since the summer of 2013 and the calculated payback period for the new heat pump system is less than 3 years.

Brian Dobbs - Performance comparison of CO2/NH3 vs. R507 in an industrial refrigerated warehouse
PDF document
published on 19 June 2014
Brian Dobbs, VaCom Technologies, compares an exiting CO2/NH3 system developed for an industrial refrigerated warehouse with a theoretical conventional system using R507. His methodology entails measuring in real-time the performance of the cascade system and then using the same refrigeration loads in order to perform an energy usage and efficiency analysis via web-accessible analysis tools. Dobbs presents his findings, which support the use of the cascade system.

Mirko Bernabei - CO2 Booster MT and LT with parallel compression and total heat recovery in a meat factory
PDF document
published on 19 June 2014
SCM Frigo’s Mirko Bernabei presents a case study illustrating the successful installation of CO2 technology in a meat factory in France. The installation is comprised of a CO2 booster MT and LT system with parallel compression and total heat recovery, which provides both cooling and heating in one unit. Parallel compression maximises the efficiency of the system when the weather is hot or during heat recovery mode in wintertime, which decreases power consumption compared with a traditional booster unit.

Rolf Christensen - Low charge energy efficient ammonia evaporator with separator vessel
PDF document
published on 19 June 2014
Rolf Christensen from Alfa Laval introduces his presentation with a general overview of Alfa Laval’s activities in the refrigeration sector and continues by comparing traditional separator designs with the Alfa Lava’s U-Turn separator while highlighting the technical and operational advantages of the latter. He goes on to present data from Alfa Laval’s installations of U-Turn separators in North America and Europe in terms of resulting savings in energy consumption and refrigerant charge requirements.
