第2章 设计参数 摘 要 PAGE I 南京市外国语学院综合楼空调系统 毕业设计计算说明书 摘 要 本次设计的是南京市外国语学院综合楼空调系统。针对该综合楼的功能要求和特点，以及该地区气象条件和空调要求，参考有关文献资料对该楼的中央空调系统进行系统规划、设计计算和设备选型。对其进行了冷、热、湿负荷的计算，还对各室的所需的新风量进行了计算。考虑到建筑本身的特点，全部采用多联式系统，该系统具有节能 节省建筑空间 施工安装方便，运行可靠 满足不同工况的房间的使用要求等优点。对于冷热源的选择，考虑建筑周边没有固定的热源供给、建筑的负荷相对较小。因此对该建筑的冷源选择采用室外空气冷却室外机以满足建筑冷热负荷的需要。为考虑室外机散热效果及建筑的美观性，并将室外机放置建筑楼顶。同时对该系统的风管、冷媒管，制冷系统等进行了设计计算。 根据计算结果，对性能和经济进行比较和分析，对设备的选择、材料的选用，确保了设备在容量、减震、消声等方面满足人们的要求,并使系统达到了经济、节能的目的，按照国家相关政策做到了环境保护。 关键词 空调；多联机；全热交换器；新风；节能 吉林建筑大学本科毕业设计 吉林建筑大学本科毕业设计 PAGE \* MERGEFORMAT 14 PAGE 15 Abstract This design is the air-conditioning system which is used for foreign language college comprehensive floor building in nanjing city. As to the office building’s functional requirements and the characteristics of this region as well as the weather condition and the air-conditioning’s requirements, reference to the relative literatures, system planning and plan calculation were chosen, and the equipment of the central air-conditioning was selected. We make the calculation on the refrigeration duty, heat load and moisture load together with the fresh air volume needed by every room. Taking into account the characteristics of the building itself, all with multi-line system, The system has energy saving building space construction, easy installation, reliable operation to meet the different requirements of the room working conditions and other characteristics. For the choice of cold and heat sources, in considering the construction of the neighbor has no fixed heat supply, a relatively small construction load, moreover, Therefore, the construction of the cold source selection using outdoor air; cooled outdoor unit in order to meet building cooling load required . To consider the outdoor unit cooling effect and architectural aesthetics and architectural roof outdoor unit placement, Meanwhile the duct system. Refrigerant pipe, refrigeration systems and other design calculations carried out. According to the calculation results as
