Finally, large ceiling fans are installed in every room, even those using air conditioning. Ceiling fans ensure that even in the absence of the necessary breezes, the airflow needed to feel comfortable in the room is provided for the users. This solution significantly reduces the amount of energy consumed. The overall consumption of the ceiling fans and the split system (the latter used to cool the technical rooms) is only 3.7kWh/m².yr compared to a classic air conditioning system in a standard building consuming 80kWh/m².yr.
Electrostatic fluid accelerator
Potential advantages of EFA cooling devices include improvement on all these issues; EFA fans produce no vibration and have no parts to wear out. Their power consumption and airflow are controllable electronically, allowing them to be run in an optimal fashion to maximize cooling and efficiency. In particular, EFA fans can produce flow which is fairly laminar, and the velocity profile of the flow can be controlled to a much greater extent than conventional fans.
Control of the airflow may have the most important impact on cooling effectiveness. Electrostatically accelerated flows have been shown experimentally to alter the boundary layer along a fixed surface so that the heat transfer rate is increased, in some cases by more than twofold.
