Thank you in advance!

Most of the time the Chillers are installed in the basement with the Chilled Water Pumps and Condenser pumps. The Chilled water pumps push the water to the air handlers on different floors and the condenser water pumps pump water to the cooling towers to reject the heat to the atmosphere.
In super tall buildings like the Burj Dubai Tower which has 41,000 tons of cooling you have equipment stations on different floors that have pumps to help with the enormous head pressure. The Central plant is still in the basement that stores 20 Centrifugal chillers and main pumps. The pumps are massive with high HP motors.
