通过现场研究，研究了紫外线杀菌辐射（UVGI）缓解冷冻水冷却盘管生物污染（生物污垢）的能量使用相关效应。在炎热潮湿的气候条件下，为运行建筑提供服务的空气处理机组中，对明显存在生物污染的冷却盘管进行5个月的监测，以确定污染盘管的基线。监测的参数包括空气流量、空气侧压降、盘管上游和下游的空气温度和湿度、冷冻水流量、进出冷冻水温度和水侧压降。按照典型的制造商指南，将UVGI线圈辐射系统安装在线圈的下游侧，然后在14个月的时间内对系统进行被动监测。通过比较基线期和辐照后期的数据来估计操作的变化。盘管空气侧压降和传热系数平均改善的95%置信区间为11。 分别为07%至11.13%和14.5%至14.6%。考虑到所涉及的物理现象的复杂性，尤其是气流和潜在负荷对空侧压降的综合影响。引用:2016年冬季会议，佛罗里达州奥兰多，会议论文

The energy use-related effects of ultraviolet germicidal irradiation (UVGI) to mitigate biological fouling (biofouling) of a chilled water cooling coil areinvestigated via a field study. A visibly bio-fouled cooling coil in an air-handling unit serving an operational building in a hot, humid climate is monitoredfor 5 months to establish a fouled coil baseline. Parameters monitored include air flow rate, airside pressure drop, air temperature and humidity upstreamand downstream of the coil, chilled water flow rate, entering and leaving chilled water temperature, and waterside pressure drop. A UVGI coilirradiation system is installed on the downstream side of the coil following typical manufacturer guidelines, and the system is then passively monitored overa period of 14 months. The change in operation is estimated by comparing data from the baseline and post-irradiation periods. The 95% confidenceintervals for average improvement of coil airside pressure drop and heat transfer coefficient are 11.07% to 11.13%, and 14.5% to 14.6%, respectively.Complexities of the physical phenomena involved, in particular, the combined effect of airflow and latent load on airside pressure drop, are taken intoaccount.
