What’s the best placement for air-cooled chiller? This article discusses CFD analysis of air-cooled chillers adjacent to a three-story building for answers. It shows that placing air intakes parallel to prevailing wind direction with at least 10 ft (3 m) of spacing between the chillers and at least 10 ft (3 m) from the adjacent building can reduce the adverse recirculation of discharge plumes into the chiller air intakes and reduce potential performance degradation.
