Professor XP is based on the induction principle. Optimal functions Professor XP´s function is based on the induction principle. Ventilation air at a given dynamic pressure is released through specially formed nozzles into a dispersal zone, thereby creating a low static pressure. This low pressure causes the warm air from the room to be sucked towards the ventilation air passing through the battery. The volume of the warm indoor air is 3 to 5 times that of the ventilation air. The air is cooled (or heated) as it passes through the battery, which consists of aluminium ribs with copper ducts filled with cold (or warm) running water. While cooling, the heat of the room is absorbed through the aluminium ribs and trans- ferred through the copper pipe to the water circuit and then goes further to a central cooling unit (see Picture 2). Despite the small external dimensions of the product, the construction makes it possible to achieve a high cooling capacity. The nozzles discharging the ventilation air are designed to maintain the Coanda effect, i.e. the adhesive capacity of the air in the duct, with a start in the nozzles. The air then fol- lows the side of the duct towards the ceiling. The side of the beam is shaped to maintain the Coanda effect across the ceiling of the room. Warm indoor air The new battery concept The new, patent pending, modular battery concept from Lindab, now has been integrated in the Professor XP. It offers 4 different performance values for 2 pipe system (cooling or heating only) with variants: min, med, high or max; and provides different cooling capacities to suit your needs. If Professor XP is to be used in a 4-pipe system (cooling and heating), these 4 variants can be combined with additional variants for heating. This provides a unique possibility to e. g. reach different capacity demands with the same product length and an architectural uniform appearence in rooms. To always get the Professor XP which suits to your needs, use e. g. the Waterborne Selector in LindQST.com • Product performance tailored to your needs • Avoid oversizing and reduce operating costs • Choose the most cost-effective solution • No waste of material and weight 4 Lindab reserves the right to make changes without prior notice 2021-11-02
