Public tender Vob/a ventilation system NEA Hauptwache General description of the service In the rooms in component G of the Hauptwache underground station, a new emergency power system is planned on the first basement level. The ancillary and technical rooms required to operate the emergency power system are mechanically ventilated. A floor-standing central ventilation unit with a volume flow of 1,900 m3/h is used in the ventilation center specially created for this purpose. The ventilation unit is equipped with an electric reheating register for heating purposes. The outside air is supplied via a ventilation duct which leads outside through the stairwell emergency exit Gw, room Hw-gub-31. The exhaust air leads outside via the same route. The air is distributed via a duct network made of galvanized sheet steel. The air volume is allocated to each person or area using volume flow controllers or control flaps. Swirl outlets are used as air outlets in the usage units. Motorized fire dampers with spring return motors are provided to separate the individual fire compartments. To avoid condensation and thermal losses, the systems are insulated in accordance with recognized technical standards. The ventilation system is controlled by a higher-level building management system. The control cabinet with the necessary active and passive components to control the system is placed in the technical room immediately adjacent to the ventilation center. Any necessary closure of public traffic areas, etc. must be applied for in good time from the relevant authorities and departments. The necessary official permits must be obtained from the beginning of construction. When carrying out the work, the contractor is bound by the instructions of the construction management.
