ESI participates in European Project directed at energy saving technologies

Press release Jan 2014

Heating, Ventilation, and Air Conditioning (HVAC) systems account for approximately 35% of the total energy consumption in residential and commercial buildings. Although today most of the energy consumed is spent on heating, there is an increasing demand for cooling solutions. The demand is expected to escalate in the coming years due to climate change. To reduce overall energy consumption, the European Commission has identified a compelling need to seek new and innovative technologies able to increase the efficiency of HVAC systems.

With this in mind, the European Commission funded the EnE-HVAC project that was launched in October 2012. The project is expected to enable the achievement of significant energy savings in future HVAC systems through use of new and innovative technologies. These technologies include nano-technological coatings and surface treatments for improved heat transfer; new nano-materials and micro-materials for improved efficiency of the refrigerants; and, improved efficiency and heat transfer capabilities of coolants via new nano-technological additives.

The ESI research team based at the CFD & Multiphysics Center of Excellence in Essen, Germany is working on the development of new methodologies for Computational Fluid Dynamics (CFD) and Multiphysics applications, particularly focusing on coupling multidisciplinary software tools.

Using the ESI advanced CFD & Multiphysics solution, the ACE+ Suite, ESI team is developing nano-technology simulation approaches for modeling specific parts of HVAC components, including anti-freezing / anti-ice surfaces, condensation drainage systems, evaporation systems and heat transfer systems.

A well-orchestrated synergy between simulation and experimental tests helps reduce the number of physical experiments needed as part of the EnE-HVAC project. Running multiple iterations of synthesis and surface manufacturing followed by laboratory tests require numerous man hours. By using initial experimental input from small scale tests and feeding this information into large scale numerical models, we gain extremely valuable input for selecting optimal surfaces for large scale physical tests. This iterative process between experiments and modeling is very valuable for getting the most accurate end results in shorter time scales".

The project engages a consortium consisting of 8 European partners, including 6 industry partners (LuVe S.p.a. (Italy), EXHAUSTO A/S (Denmark), ESI GmbH (Germany), Dansk Varmepumpe Industri A/S (Denmark), Carbodeon Ltd. Oy. (Finland) and Vahterus Oy (Finland) and, two research institutions (the Danish Technological Institute, (Denmark), and IK4 Tekniker, (Spain)).
