Abstract
This paper presents the impacts of UVGI systems on cooling coil performance in hot and humid climate. The purpose of this study is to investigate the effects of UVGI systems on pressure drop reduction and air-side heat transfer enhancement. Speed variation experiments were employed before and after UVGI operation to comparatively demonstrate the effects of UVGI systems. The results show that pressure drop is more sensitive to the impacts of UVGI than heat transfer coefficient. It takes longer time for UVGI system to take effects on heat transfer coefficient than on pressure drop. In addition, bio-fouling has much more significant impacts on heat transfer reduction than dust fouling. The impacts of dust fouling on pressure drop are more significant than on heat transfer rate. The UVGI system has been in operation for 8 weeks by mid March and the experiment is still in progress. The future impacts will be evaluated as the experiment continuous.
