Air Conditioning and Ventilation Design of the Zhangjiagang Hotel

Zhangjiagang Hotel is a closed high-rise four-star hotel with complete intelligent air conditioning system. Cold source for the system comes from three water-cooled chillers with screw compressor while beat source is supplied by three oil-fueled steam boilers. For the convenience of maintenances in emergent cases, a parallel system is employed for the circulating water pumps. Constant air volume(CAV)system is applied for the large space of the first to the fourth. For the standard floors, air conditioning system consisting of fresh air handling units and fan-coil units will be installed. As for smoke management design, positive pressure smoke-proof system have been provided for the fire control lift wells, which is based on both domestic and international experiences. The air conditioning system is controlled by the Building Automation experiences. The air conditioning system is controlled by the Building Automation System(BAS) of the building. A summary of commissioning and operation practice is given at the end of this article.
