BUILDING WITH DEMAND-CONTROLLED HEAT EXCHANGE SYSTEM FOR VENTILATION, HEAT EXCHANGE VENTILATION SYSTEM AND HEAT EXCHANGE SYSTEM

摘要

The invention relates to a filter element for a heat exchange system, said filter element being provided at an interface between an inlet branch of the heat exchange system via which an air stream is supplied and an airflow passage through a heat exchanger of the heat exchange system. The filter element comprises air filtering and distribution means for filtering the supplied air stream and distributing the supplied air stream over the area of the interface. The air filtering and distribution means has a corrugated, oblong shape having peaks and valleys extending in a longitudinal direction of the filter element, such as a first filtering material pleated in fanfold manner having longitudinal pleats.
