湿度对建筑空调系统设计及运行影响探讨
Influence of humidity on building air conditioning system design and operation
摘要：
以某动物实验中心全新风空调系统为例，分析其在设计阶段对湿度控制的考量，结合能耗模拟软件EnergyPlus，探究湿度对空调系统运行阶段的实际影响。对比模拟与实测值发现，达到设计要求的所需冷量比实测冷量大42%，说明实际运行未满足设计要求。进一步计算空调系统的输出显热比发现，在某些条件下，设备实际的输出显热比为0.374，大于设计所需的输出显热比0.355，从而导致室内实际参数偏离设计值。认为在设计阶段应考虑湿度的影响，尤其是设计潜热负荷占比较大的空调系统。
Abstract：
Taking the all outdoor air conditioning system of an animal experiment center as an example, analyses the consideration of humidity control in the design stage. Combining EnergyPlus, an energy consumption simulation software, explores the practical influence of humidity on the operating phase of an air conditioning system. By comparing the simulated and measured values, finds that the required cooling capacity to meet the design requirements is 42% higher than the measured cooling capacity, indicating that the actual operation fails to meet the design requirements. Further calculating the output sensible heat ratio of the air conditioning system, finds that the actual output sensible heat ratio of the equipment is 0.374 under some certain conditions, which is higher than the design sensible heat ratio of 0.355, resulting in the deviation of the actual indoor parameters from the design value. The influence of humidity should be considered in the design stage, especially at the high latent heat load.
