EUROVENT KÄLTE KOLLOQUIUM: Fifth presentation
"Heat dissipation in the logistics cold store."
Evapco Europe GmbH presented on behalf of members of the Eurovent Cooling Tower (CT) working group, giving a thorough explanation of the different types of cooling towers, their functional principles, advantages, and challenges for each type of technology.
About the EUROVENT KÄLTE KOLLOQUIUM
Over two days, from 4th - 5th June 2024, operators, planners and manufacturers explored reliable refrigeration systems for the cold chain, "From Farm to Supermarket," in Wiesbaden, Germany. A comprehensive technical programme took delegates from theory to practical, with a mix of seminars and excursions, perfectly blended to encourage learning, discussion and networking in inspiring surroundings.
Organised by Eurovent Certification and COOLPLAN, with media partners CCI and KKA, day-one was hosted at the historic Kloster Eberbach. The extensive technical programme scrutinised the latest trends in refrigeration, decarbonisation and boldly tackled issues such as underperformance and its impact on food quality and energy efficiency.
Day-two put the theory into practice, with the chance to go explore cold food chain technology in its natural habitat, with excursions to a green farming market and NH3/CO2 logistics warehouse.
The presentation
"Heat dissipation in the logistics cold store."
On day-one, the afternoon sessions began with the fifth presentation of the day from Michael Rabenstein, Country and Branch Manager, of Evapco Europe GmbH. Michael started with a brief overview of Evapco before turning attention to the role of the Eurovent Working Group for Cooling Towers.
His presentation then moved onto a thorough explanation of the different types of cooling towers including wet open cooling towers and hybrid cooling towers (both certified under the Eurovent Certified Performance mark) and adiabatic condensers/recoolers and dry condensers/recoolers. Michael explored the functional principles, advantages and challenges for each type of technology.
He next focused in on the role of certified performance. Emphasising that uncertified products pose the risk of underperformance, and that unverified product data was open to interpretation. Using a case study, Michael showed the impact of uncertified data and the resulting underperformance. Not only did the uncertified system have a higher power requirement, but with the system not performing as promised, he highlighted the trouble that would emerge at handover time. With the message on certification firmly delivered, Michael showed delegates how to access certified data via the Eurovent certified product directory.
Back on the topic of cooling towers, he gave a summary of system concepts and accessibility, before moving onto maintenance and control. Pointing out the huge importance of regular maintenance, he delved into the requirements for components such as heat exchangers, the external and internal unit and the water cycle. Michael showed delegates an alarming array of nightmare images of poorly maintained systems, before asking the audience for questions.
