3、不稳定，这促使中央空调系统软件变工况性能好，调整灵巧；大型购物中心每天都在营业，而且四季天气变化比较大，这使得商场的中央空调运行情况要与天气状况相匹配，既要在大多数低负荷情况下有不错的经济发展性能，又要满足某些恶劣天气的高峰负荷。人员流量大、人员密度大、空调冷负荷指标高、运时间长是商场建筑的特点。温度、环境湿度、洁净度和排风量会影响顾客和商场中的工作人员对室内环境的舒适感觉。室内环境质量低于标准会危害人们身心健康和员工工作效能。商场建筑的室内空气环境问题已引起商业界的更多关注。商场空调环境关键目地是提供房间内适合的温度湿度，创造使消费者感到舒服的冷、暖购物环境；同时减少房间里物品（包括服装、家
4、具等）变质的可能性；并且能让员工在舒适的环境里进行工作。建筑冷负荷计算，管路的水力计算，根据空调系统的主要工作原理、设计原则、控制方法和系统适用性分析进行合理布置，按照需求选择离心式冷水机组，以上就是主要的设计内容。通过风机盘管加新风的方式，不断将冷量供给房间，用来调节和控制室内空气参数，以求提供一定舒适度要求的人工环境。关键词：空调系统； 舒适性； 稳定性； 负荷AbstractWith the significant improvement of Chinas economic strength, peoples quality of life has been greatly impro

Special central air conditioners for large，medium and small shopping malls can adjust the temperature and

Nowadays，because the competition in the market of commercial enterprises is more and more fierce，the natural environment for shopping has a great relationship with the companys
7、profits，and the staff in the shopping malls are relatively dense，especially on national legal holidays，the central air conditioner has a large cooling load in summer，a large output of fresh air system，and a smaller heating load in winter. Asymmetry and contingency of peoples flow in the store make t

The store operates every day，and the climate problem is relatively serious in the four seasons. It is stipulated that the central air-condition

It is necessary to consider the peak load of some extreme weather and have good economic development performance under low load conditions in most time periods. Office building is a public place with a very large population. Temperature，
