Abstract: A partition device for a reactivation section of an air treatment rotor in an air treatment apparatus includes at least one first partition member provided with a first cover area, an inlet opening and an outlet opening for a reactivation air stream and an actuating member for moving and positioning the at least one first partition member or a part of the at least one first partition member in relation to a center axis of the air treatment rotor to regulate the area and shape of the reactivation section.

Abstract: The invention relates to a method, performed by a control device (100), for cleaning an evaporative humidifier and cooler apparatus (1) for humidification and cooling of air, the apparatus (1) comprises: a cooling and humidification media (2), which is configured to receive and evaporate a fluid (4); a fluid distribution element (6), which is configured to distribute the fluid (4) to the cooling and humidification media (2); and a tray (8) arranged to collect fluid (4) downstream of the cooling and humidification media (2), wherein the fluid (4) distributed by the fluid distribution element (6) is collected from the tray (8).

Abstract: The invention relates to a partition device (6) for a reactivation section (18) of an air treatment rotor (2) in an air treatment apparatus (1). The partition device (6) comprises at least one first partition member (31) provided with a first cover area (44), an inlet opening (46) and an outlet opening (48) for a reactivation air stream (22) and an actuating member (29) for moving and positioning the at least one first partition member (31) or a part of the at least one first partition member (31) in relation to a center axis (8) of the air treatment rotor (2) to regulate the area and shape of the reactivation section (18). The invention also relates to an air treatment apparatus (1) and a method, performed by a control device (25), for controlling an air treatment apparatus (1). The invention also relates to a computer program product and a computer-readable medium.

Abstract: An air handling system includes a movable evaporative media section. The movable evaporative media section is movable between a closed position and an open position. When the movable evaporative media section is in an open position, the movable evaporative media section exposes an opening to the air flow and is positioned to allow at least a portion of the air flow in the volume to flow around the movable evaporative media section and through the opening.
