Intelligent HVLS assisted ventilation for office environments

The project develops a new ventilation and cooling principle for typical offices. Rather than lowering the temperature in rooms with energy intensive air conditioning systems, cooling and a good thermal indoor climate are obtained by creating air movement in the occupancy zone. The solutions are developed for office spaces and large-scale offices with ordinary ceiling heights. The air movement is created by newly developed HVLS * fans, which are intelligently controlled in cooperation with ventilation, cooling and heating - and according to the outdoor and indoor temperatures, load, office layout, room dimensions, solar gain, user preferences, time of the year, etc.

Today, HVLS fans are sold for high ceilinged rooms, such as large warehouses and sports centers, with other indoor climate requirements and use than office space. These are "stand-alone products" with simple speed control and with a timer. The present project develops an intelligently controlled HVLS solution for typical office premises with room heights of 2.5 to 4 meters. A solution with intelligent operation also including the building’s ventilation, cooling and heating system.

The required electricity consumption to ensure a good indoor climate in office premises can typically be reduced by 30-35%.

A configuration and dimensioning tool is developed for consultants, distributors, installers, etc., ensuring that the new type of ventilation system is designed and installed correctly

Note *: A HVLS-fan is reminiscent of a propeller fan hanging from the ceiling. But they are not comparable. A HVLS-fan has a diameter of at least 2 meters and rotates slowly and moves very large volumes of air. While a propeller fan has a very high rotational speed and generates more noise.
