[暖通供热论文] 摘要： 某会展中心暖通工程竣工验收后，发现了一些问题：冷却水泵、冷却塔性能均达不到设计要求的参数。其余，如蒸汽系统、蒸汽凝结水排放，空调冷（热）水室外管沟、冷负荷调节等方面均存在一些问题。经一年多的整治和改造，整个空调系统基本达到设计的要求，均能正常投入运行。本文简单介绍了这些问题的解决措施，仅供同行参考。

The summary of the system of the central air-condition in the exhibition
Abstract： The system of the central air-condition in the exhibition hall was finally fixed, but we found several problems. Some parameters can’t reach the original designing. Such as the cooling pumps and the cooling towers, additionally some disadvantages lied in the system of the vapor, the transpiration of the congulated water and the cannels which were used to put the cooled (heated)water pipes. After discussing these problems carefully, we excogitated some ways to solve. Now the system of the central air-condition in the Ningbo international exhibition reaches the requirement of the designing. The article introduces these ways. We hope these projects will provide references to the craft brothers.
一、工程概况：
某会展中心，是一座现代化的展览中心，其内共有建筑物6座，4座展馆，其余为会议楼、商务楼。会展中心总建筑面积近9万㎡，占地约400亩。建筑群采用大型集中中央空调系统，总制冷量为1600万大卡/小时。集中冷冻机房内设置450万kal/h的溴化锂冷水机组3台，200万kal/h的溴化锂冷水机组1台。配备28台逆流式冷却塔，冷却水循环泵7台。……
