- Abstract:
- The design of water supply and drainage system in super highrise fivestar hotel is complex. It is difficult to convert water supply and drainage pipelines with special shapes. The shock absorption and noise reduction requirements of fire pump room on the refuge floor are high. There is a high correlation between the hot water system and HVAC system selection. The selection of water consumption, water quality analysis and treatment, water supply system zoning, hot water source selection, hot water system selection, drainage system conversion, ventilation setting mode, fire protection system zoning and sponge city design of Nanjing Grand Hyatt Hotel water supply and drainage were analyzed and discussed. According to the current codes, local regulations and hotel property requirements, a relatively safe and reliable fire protection system and economical, reasonable and comfortable cold and hot water and drainage systems were selected. The fire protection system adopted the form of fire pump transferring and supplying water in series. Domestic cold and hot water systems in low area adopted the form of water pump frequency conversion to supply water. The high area adopted the combined water supply form of gravity water supply from the water tank and the frequency conversion water supply from water pump. The drainage system adopted the form of sewage and waste diversion. The design can be used for reference by relevant designers.
