The placement of your chiller installation depends on the type of chiller you have. Air cooled packaged chillers, they should be placed outside on a level surface. This can be on a concrete pad or on a roof that can support the operating weight of the chiller. A split-system air cooled chiller will have the main control unit indoors and the condenser fans located outside to expel the heat taken away from the process to the ambiant air. Water cooled packaged chillers are typically located indoors as they are connected to the building's piping.
