摘要
天津市服务综合楼总建筑面积43318m2，地下室建筑面积为9384m2。本空调工程设计冷负荷采用谐波分析原理计算法；空调湿负荷的计算方法采用的是经验数据概算法；本工程根据各空调房间热湿负荷的特点及使用功能等工程实际，进行空调分区，此次设计只选做了一二楼层，分为六个中央空调区和多个局部空调区，同时根据各空调区的使用特点和负荷特点，合理地设置六个中央空调系统及多个局部空调系统，以有利于调节运行；本工程制冷机组采用制冷量大、效率高、噪声低的双压缩机-螺杆式水冷机组，并选用两台，其中一台兼做备用。
为消除空调房间内的余热和余湿，须对空气进行热湿处理，并经严格的热湿处理计算确定空调机组的冷热湿量和选用符合要求的空调机组。
本工程空调水系统庞大而复杂，且容易产生水力失调，所以选用了水力平衡性较好的同程式系统。同时要求配有比较完善的自控系统。

ABSTRACT
Bai-Si-Te synthetic building’s floor area of tianjin total 43318m2,the air conditioning area is 9384m2.In this air conditioning engineering,the computation of the designed cooling load used the overtone analysis principle;The humidifying treatment load of an air conditioni-ng system computational method which used was the empirical data generally algorithm;Acc-ording to project reality for instance the heat-wet load characteristic and using function of va-rious air conditioned room and so on,carried on the air conditioning district for this project,and divided into six central air conditioning areas and many partial air conditioning for be-nefitting adjustment and workingand simultaneously,according to the handling characteristics and the load characteristic of various air conditioning area,reasonably established six cen-tral air-conditioning systems and many partial air-conditioning systems;This project refriger-ation unit uses double compressor-screw rod type water cooling unit of which the refrigerati-on quantity is high,the efficiency is high,the noise is low,and concurrently selects two,one does spare.
In order to eliminate the over heat and the over wet in the air conditioned room,we must carry on heat-wet treatment to the air which is inputted,and after the strict heat-wet treatment computation,determinate air-conditioning unit's cold and hot and moisture content,and select the air conditioning units which conform to the request.
The aqueous system in this air conditioning project is huge and complex,and also is easy to have the water-power imbalance,therefore here has selected the same formula sys-tem which water power balanced state is better.Simultaneously it requests to have the quite pe-rfect automatic control system.
Key words:central air-conditioning,partial air-conditioning,fan-coil,air conditioning unit
