南京市某航海博物馆空调系统工程设计(任务书,计算说明书12000字,PDF图10张)
摘要
本工程为南京市航海博物馆通风空调系统设计工程，项目位于江苏省南京市。南京市航海博物馆共四层，层高6米，建筑功能复杂多样，包括恒温恒湿展区、普通观光展区、恒温恒湿库房、普通库房、电影院、天体馆、商店等。
工程结合南京地区气候特点、建筑功能，勘察调研当地地理环境、资源分布、市政能源供应，综合考量，进行冷热源方案经济性分析对比，选择冷热源方案为江水源热泵。利用Revit和Dest软件建立博物馆的土建模型，利用软件进行建筑全年负荷模拟，典型房间手算验证，得出建筑全年动态负荷，作为冷热源方案设计，空调分区划分、空调系统设计依据。
根据房间功能、防排烟分区合理划分空调系统，一层中庭大厅采用全空气系统，上送侧回，分层送风，一层百叶风口侧送，上层喷射风口喷射送风。电影院天体馆，人员密度大，考虑观众体感舒适度，结合卫生要求采用座椅送风。
本次设计进行了充分的调研分析、模拟论证，选择切实可行得设计方案，提高能源利用效率，降低运行费用，力求符合绿色经济得主流设计趋势。

Abstract
This project is the ventilation and air conditioning system design project of Nanjing Zhenghe navigation museum, which is located in Jiangxinzhou, Nanjing city, Jiangsu province. Zheng he navigation museum has four floors with a height of 6 meters. The architectural functions are complex and diverse, including constant temperature and humidity exhibition area, general sightseeing exhibition area, constant temperature and humidity warehouse, general warehouse, cinema, celestial museum, store and so on.
Based on the climatic characteristics and architectural functions of Nanjing region, the project investigated and investigated the local geographical environment, resource distribution and municipal energy supply, comprehensively considered, analyzed and compared the economy of the cold and heat source scheme, and selected the cold and heat source scheme as the river-source heat pump. Using Revit and DeST software to build the civil model of the museum, using the software to simulate the annual load of the building, and verifying the typical rooms by hand, to obtain the annual dynamic load of the building, which can be used as the basis for the design of cold and heat source schemes, air-conditioning zoning and air-conditioning system design.
Air conditioning system is reasonably divided according to room functions and smoke prevention and exhaust zones. The atrium hall on the first floor is equipped with an all-air system, with upper feed side to back, layered air supply, side feed louver air outlet on the first floor, and air injection outlet on the upper floor. The nudist hall of the cinema has a high density of people, considering the comfort of the audience, and combining with the hygiene requirements, seats are used for air supply.
This design has been fully investigated, analyzed and simulated, and the feasible design scheme has been selected to improve energy utilization efficiency and reduce operating costs, striving to meet the mainstream design trend of green economy.
