Cooling Tower/ Chiller/ Generator Rooms Simulations

Recirculating the cooling tower discharge into the tower intakes can negatively influence the performance of cooling towers, chiller yards, and condenser units that are close to other cooling equipment. Current design approaches frequently take this discharge re-ingestion issue into account. CFD analysis is used to examine the worst-case discharge recirculation effects on the operation of cooling towers and chillers as well as the impact of hot, humid air on the surrounding air. The bounding design values of the increase in the wet bulb temperature at the tower intake due to recirculation and interference are calculated considering the various cooling tower operation conditions, ambient temperature, humidity, wind conditions, and the impact of nearby high-rise buildings.
