Dynamic free cooling

The goal of the project "Dynamic Free Cooling" was to develop an energy-reducing free cooling system for buildings. The project is based in the ventilation unit MicroVent, developed in an earlier EUDP project, and has been working to find opportunities and limitations in the use of free cooling to cool rooms with outdoor air and with the best possible comfort for the occupants of the premises.
The project has developed a comfort module that compensates for temperature by the room temperature, whereby comfort nuisance. By combining MicroVent with komfortmodullet and strategies for comfort control has designed a multifunctional system that can comply buildings varying demand for cooling and ventilation.

The results of the project is a prototype of a system that provides essential
energy and related operational savings in building operation. The concept is highly suitable for the renovation of the existing building stock, as the construction costs of the multi-functional system is lower compared to
existing technologies.

An experience from the project is that the current grilles to MicroVent (without mixing module) works well already, even with relatively large temperature difference between supply air and room air. This experience speaks to explore the possibility of implementing free cooling without comfort module further. Inventilate will work on this to determine whether there should be sales of free cooling system with comfort module or whether to create a simpler and cheaper system without comfort module.
