文档介绍：设计总阐明
本设计为上海市某办公楼空调通风系统设计。该办公楼属大型办公建筑，总建筑面积约为55000㎡。地下两层，地上二十八层，。地下两层为车库及设备用房，地上二十八层均为办公用房。该建筑旳重要功能间有办公室、会lding. The building’s height is . In the building there are offices, meeting room, reception room and so on. Cooling load for the entire floor is 3080 kilowatts. The whole floor using Central Cooling Chillers to focus on the way .
The main rooms in the building are offices, most of them are very small, and the rooms are not connected. So the selected air-conditioning system should be able to achieve independent control of each room. Considering the various factors, determine to select the fan-coil system plus fresh air system. Arrangement in the room ceiling fan coil units, using the dark form of equipment. With this system, fresh air units deal with the introduction of a new wind to the indoor air enthalpy value, do not bear the load indoor. The fan-coil units bear all cooling load and part of its new rheumatoid load. Fan-coil plus an independent air system sent by the Venetian and the under side air delivery. Closed water system with a dual-track program, three cold-water pump, dual-use a prepared; cooling pumps three elections, one prepared by dual-use.
After the cooling load calculation, we can select the refrigeration machine , the fan coil units, the wind pipe and water pipes, the fresh air units and pumps. Read the relevant air-conditioning design manuals and complete the final design of the air-conditioning system.
Key words: PAU+FCU systems; load; pipeline design; refrigeration machine
