The next Chillventa takes place from 14–16 October 2014. The International Trade Fair for Refrigeration, Air Conditioning, Ventilation and Heat Pumps starts on Tuesday and runs for three full days. After the extraordinary success of the last event, the event team is looking optimistically to Chillventa 2014 and is confident that the importance of this exhibition for the sector will continue to grow. Around 1,000 exhibitors are expected this year – a new record.

Knowledge transfer is also top priority during the exhibition from 14–16 October, when more than 125 interesting presentations are lined up for visitors to the forums in halls 1, 4A and 7. Bernhard Rieger from Mitsubishi Electric Europe BV speaks on "Hotel air conditioning with maximum comfort – patented VRF R2 heat pump system for simultaneous cooling and heating". Hans Kaut GmbH is represented by Sascha Wittenstein, who delivers the paper on "A pleasant climate for your business". Dr. Nikolaus Meyer of Geo-En Energy Technologies GmbH deals with air conditioning of large buildings in his paper and shows efficient solutions with geothermics and photovoltaic systems. Another paper by Ulf Cartellierie of Stulz GmbH provides ideas on "Why the discharge of large thermal loads can cause difficulties with air conditioning". These are just a few of the many presentations.

Applications & Training & Regulations
Hall 1 focuses on application, training and laws, standards and regulations. A key role is played by the new F-Gas Regulation and associated new developments in refrigerants with low Global Warming Potential. The application of NH3 in faraway countries is also on the agenda. At the forum on Tuesday morning, for example, refrigerant manufacturers Arkema, DuPont and Honeywell present global solutions for the use of low GWP refrigerants. The necessary oils for these refrigerants are dealt with in addition. A practical report by the Bundesfachschule Maintal (Federal College of Refrigeration and Air Conditioning Technology) shows the use of the refrigerant R-290 (propane) and discusses its possible commercial applications. Dave Godwin from the U.S. Environmental Protection Agency (EPA) will also speak on refrigerants at the forum on Wednesday morning.

Refrigeration
The products presented in hall 4A include components, refrigerants, electronic controls and the latest monitoring systems. Here the classic refrigeration for commercial and industrial purposes dominates. The initiative for more efficient refrigerants is just one focus of this forum. The presentation by Danfoss on "Optimized plant efficiency through dynamic COP measurement" tackles a particularly interesting topic. The necessary parameters are detected by the specially developed module and reproduced as corresponding current COP, which is then compared with the ideal COP for the system. The comparison of these two figures enables the system to be optimized. The forum in hall 4A concentrates on refrigeration.

Air Conditioning – Ventilation – Heat Pumps
Hall 7 focuses on air conditioning, ventilation and heat pumps. The impact of the new F-Gas Regulation is also clearly noticeable in the presentations here. Other topics presented include heat transfer in buildings, the use of renewable energy sources, efficient air conditioning and ventilation systems, and ecodesign. The presentation on "Economic Energy and Climate Management by DAIKIN Cloud Services" shows the possibility of obtaining precise statements on current operation, system reliability and energy consumption for already installed or new Daikin VRF systems with the existing bus topology and knowledge of the components used.
