Title The HVAC Design of a Hotel in Beijing
Abstract
The hotel is located in Beijing, the construction of which is one underground floor and fourteen floors on the ground. The underground floor is used as the warehouses and equipment rooms. The hotel requires heating, ventilation and air conditioning and smoke control measures if it is necessary. The total construction area is 15000 square meters, and the area which needs air-conditioning is 12034 square meters. The employee dining room, the multifunction room, the ballroom and the hall can install the full air system, and other rooms can install fan coil units with fresh air system; each room uses square diffusers to deliver air and single shutter air inlets in order to return air to the ceiling. Bathrooms are equipped with ventilating fans. Stairwells should be set with pressurized air supply system, and the basement should be set with the mechanical smoke extraction system and the mechanical ventilation system. The cold source comes from two water-cooled screw chillers. The heat source comes from the municipal heating network, which also needs plate heat exchanger to transfer the heat. Cooling towers is placed on the roof of the podium.
