摘要:本课题题目为上海市某宾馆空调系统设计。该宾馆为为8层建筑建筑总面积约4000m2,一层为餐厅层高为4.5m,其余七层为客房,层高为3.3m。
在了解建筑物概况及设计参数、冷负荷的情况下,对系统方案进行初步确定:由于该宾馆层数较少,使用人员不多,制冷负荷较低,我们选择半集中式中央空调系统。为了更好,更经济的对房间承担冷负荷及湿负荷,选取空气水系统的设计方案。具体设计按送风参数的数量,送风量恒定与否,所使用空气来源和房间的控制要求设定。在完成方案的确定后,进行风系统和水系统的阻力计算,在计算过程中,综合经济因素,质量因素等确定管材,确定风管水管管路路径,得出最不利路径的阻力,结合冷负荷,送风量等选择相应的空调末端产品以及辅助设备。23486

THE HOTEL AIR CONDITIONING SYSTEM DESIGN in SHANGHAI CITY
Abstract:This project is a hotel air conditioning system design in shanghai City. The building designed in shanghai is a eight-storey hotel. The first layer is a restaurant, the height of witch is 4.5 m. The remaining four are the guestrooms, the height of witch is 3.3 m. with a total floor area of approximately 4000 square meters.
Initially identify the system program after understanding the building profile and design parameters and the cooling load: For the reason of the hotel's low-rise, the use of the cooling load is low, we chose a semi-centralized central air conditioning system. In order to be more economical commitment to the room cooling load and the moisture load, select the design of the air-water system. Specific design of air the number of parameters, the air flow constant, the use of air source and room control requirements set. After the completion of the program is determined, the calculation of resistance of the air system and water system should be started. In the calculation process, the comprehensive economic factors, quality factors to determine the pipe to determine the path of the duct hose pipe to draw the most unfavorable path of resistance, combined with the cooling load, air supply, select the corresponding end of the air-conditioning products as well as auxiliary equipment.
