[-] text [+]

We are excited to announce the second round of case study selections for ATMOsphere Asia 2014. Panasonic, Mayekawa, Nihon Netsugen Systems, CAREL, Danfoss and KAV Consulting will present their innovative technology case studies in the fields of commercial and industrial refrigeration. The final round of case studies selected will be announced early January 2014. 

As the event is quickly approaching, don’t miss your chance to attend the first-ever ATMOsphere Asia 2014. Register now!

Selected case studies:

Commercial refrigeration

Introduction of energy savings by CO2 refrigeration systems in SM/CVS by Gaku Shimada, Panasonic

Presenter Gaku Shimada from Panasonic introduces how a CO2 refrigeration system works efficiently in a CVS and SM in Japan. The presentation will be based on monitored data throughout the year. The key technology and product structure implemented to achieve efficiency will be presented. Future prospects of CO2 technology application and other issues will be addressed.

Development of CO2 cooling system for supermarket by Katsuhiko Harada, Nihon Netsugen Systems

Nihon Netsugen Systems is developing a CO2 cooling system for medium and large size supermarkets. Partnering with German compressor manufacturer GEA Refrigeration Technologies, Nihon's prototype unit includes GEA Bock's CO2 semi-hermetic reciprocating compressors. The prototype unit is a booster system, which consists of transcritical and subcritical compressors. One unit can cool down both medium temperature and low temperature domestic cabinets. It can also create hot water with a heat recovery function. The first supermarket installation is planned for 2014.

Sustainable CO2 control solutions for small supermarkets and convenience stores by Michael Englebright, CAREL

In this case study, Michael Englebright from CAREL will demonstrate that transcritical CO2 can be used in small and very small refrigeration systems as safely and as simply as in bigger commercial refrigeration applications. The presentation also focuses on how to disseminate the know-how and provide the technical support needed from project design to commissioning and after sales to guarantee a similar momentum around transcritical CO2 for small footprint systems as in traditional retail applications.

Industrial Refrigeration

Industrial refrigeration system using NH3/CO2 refrigerant “NewTon” by Hideyo Asano, Mayekawa

Hideyo Asano from Mayekawa introduces the “NewTon” system which was developed to reduce CO2 emissions produced by the industrial refrigeration market. The author will also present and describe the technical specifications and results of several reference cold storage installations in Japan and in Indonesia.

NH3/CO2 cascade system, successful case in China
by Hernan Hidalgo, Danfoss

Hernan Hidalgo from Danfoss will present a successful case study from China where a NH3/CO2 cascade refrigeration system was installed in a Chinese warehouse. Combining NH3 for the high-temperature side and CO2 for the low-temperature side, this case study demonstrates a safe and more energy efficient solution that can operate reliably under varying external conditions. Hernan Hidalgo will show an analysis of energy consumption between the previous system and the new system, proving energy savings of around 10%.

Replacing an air cooled R22 system with an evaporative condenser cooled ammonia system by Klaas Visser, KAV Consulting

KAV Consulting Pty Ltd (KAVC) was commissioned by Wakefield Transport Group (WTG) to advise on tenders received from design and construction refrigeration contractors, to augment the capacity of an R22 refrigerated Propylene Glycol (PG) system used for the cold sterilisation of oranges against the common fruit fly for export to Asian countries.

After examining past production patterns, quantities of fruit cold-sterilised, electrical energy consumed, and Maximum Demand (MD) measured in previous years, KAVC advised the client to consider replacing the existing air cooled R22 system with a custom designed ammonia system with more than double the capacity of the R22 system, allowing the cold sterilisation capacity to be more than doubled without the need to augment the power supply capacity from the grid. The system ran from the end of April till the end of October 2013. The presenter, Klaas Visser, will show its results compared to the two previous years. He will also describe further capacity improvement planned for this coming season.
