Energy efficient ventilation systems

Changes of actual load often lead to trouble with the operation of the ventilation system. The design data are no longer correct if, for any reason, the actual load has permanently changed during the usage. The proposed ventilating system maintains the most commonly developed harmful gaseous contaminant content below the permissible level in spaces with forced ventilation. Sensors are mounted in every room, in a given height. By following the demand, the supplied fresh air volume matches the momentary load. Thus, possible health hazards can be mitigated and acceptable life- and working conditions can be maintained in these spaces. The requested indoor air quality is assured in any ventilated space without disturbing the air supply to other spaces. One of the main advantages of this system is that no energy is wasted for the handling of any excess air when the system load is below the design load.
