Title A hotel air conditioning design of Ningbo City
Abstract A hotel located in Ningbo City that latitude is 29°52. The climate in Ningbo city is that when the summer is hot and winter is cold. The market structure is that there are two floors in the underground and seventeen floors on the ground. Its area is 22515 square meter, its height is 68.1 meters. Going on the ventilation and air conditioning engineering design according to buildings and the local climate characteristics, which is including the design of the air system, water system and the cold and heat source and so on.
The design uses a water cooled screw chillers for air-conditioning cold source, gas boiler as a heat source. Conditioning mode, up spaces such as shopping malls, halls, etc. with full air system; offices, hotel rooms, etc. using an independent fan coil air system. All-air systems use flat square diffuser jets form rather independent fan coil air system uses Louver side to send the form. Water system with closed horizontal vertical DRS. Wei stairwell positive pressure air supply system; hallway with mechanical exhaust system.
Keywords All-air system Fan-coil independent open air system
