暖通空调系统占典型建筑能耗的30%至50%；在炎热潮湿的气候中，它更接近该范围的上限。对建筑暖通空调系统实施有效的节能措施，可以降低建筑能耗，降低高峰需求，提高建筑舒适度。近年来，地板下空气分配系统（UFADS）被用作暖通空调系统的一种创新方法，以提供最大程度的乘员舒适性、改善室内空气质量和节能。在这项研究中，我们评估了位于湿热地区的教育大楼中UFAD系统的运行和性能。 该研究发现，即使在炎热的夏天，该建筑也过冷，UFAD系统也处于再热模式。建议根据建筑负荷优化现有空气处理机组（AHU）排放空气温度（DAT）设定点重置，并将地板下静压降低一半，以改善建筑舒适性和能源性能。据估计，实施优化的AHU DAT设定点重置计划可潜在减少约30%的UFAD系统热衰减。将地板下的静压降低一半可能会将系统的最小气流速度降低约30%。 引文:ASHRAE论文CD:2014 ASHRAE年会，华盛顿州西雅图

The HVAC system accounts for 30 to 50 percent of a typical building's energy consumption; in hot and humid climates it is closer to the upperend of that range. Implementing effective energy saving measures for the building HVAC system can reduce the building energy consumption,reduce peak demand, and improve building comfort. In recent years, under-floor air distribution system (UFADS) is used as an innovativeapproach to HVAC system to offer utmost in occupant comfort, improved indoor air quality and energy savings. In this study, the operation andperformance of a UFAD system in an education building located in a hot and humid area is evaluated. The study found the building wasovercooled and the UFAD system was in reheat mode even in hot summer. Optimizing existing air handling unit (AHU) discharge airtemperature (DAT) set point reset based on building load and reducing under-floor plenum static pressure in half are recommended to improvebuilding comfort and energy performance. It is estimated that implementing the optimized AHU DAT set point reset schedule can potentiallyreduce about 30% of the UFAD system thermal decay. The reduction of the under-floor plenum static pressure in half can potentially reduce thesystem minimum airflow rate by about 30 %.
