This design content for the design of Nanjing Dragon Hotel9 floor hotel building in central air conditioning system. One of the hotel building is an important symbol of buildings, its construction level and equipment level is also a national modernization degree and level of technology. This design according to the characteristics of hotel air conditioning, according to the energy structure and energy in the Nanjing area, the use of the status and the present level of economic development, from the point of view of energy-saving design, design of cold and heat sources of the building.
The Department of architecture of catering, entertainment, accommodation integrated comprehensive building, is a frame structure, located in the Nanjing area, a total of 9 on the ground floor, the floor height of 33.5m, comprehensive hotel load characteristics: a hotel, hotel lobby, with large population flow. A layer of shops along the street with a display window,window larger difference between indoor and outdoor illumination, see the room is dim so often the hotel bottom illumination of very high from outdoor, lighting load due to personnel intensive, fresh air load is large. The hotel is a place of personnel flow, so the temperature and humidity, indoor air cleanness and fresh air volume, pide the calculation process should be fully aware of the building inside and outside the area in the load, and a more accurate calculation of cold, heat load.
The design content includes: Calculation of air condition cold load;determine the air conditioning system design and system; the selection of cold and heat source; air terminal handling equipment selection; design and calculation of the wind system; selected indoor air and airflow organization form; design calculation, water system layout and hydraulic.

1 绪论
1.1我国暖通空调的现状
在社会经济飞速发展的今天，我们的居住条件日益改善，人们对生活环境的舒适性越来越重视，对采暖通风空气调节的需求越来越大，对中央空调的舒适性、节能环保、室内空气品质更加关注。因此，设计一项节能、舒适、健康的中央空调系统具有很重要的实际意义。
空调系统创造了一个室内舒适的环境,同时也在消耗着大量的能源。据美国对公共建筑和居住建筑能耗的统计，有1/4的建筑能耗用于空调而在我国一般中央空调系统能耗更是约占了整个建筑总能耗的50%左右。我国作为世界公共建筑中的能耗大户,节能迫在眉睫，然而中央空调系统的节能具有很大潜力,在节能减排方面具有深远的实际意义。空调节能不仅是一个技术措施，同时也是与国家节能政策方针密切相关的综合问题。
