Air cooled chillers are the "simplest" of the chiller systems. Most of them very closely resemble a split system condenser or RTU. This makes them an easier entry point to learn chillers. Typically an air cooled chiller will have the condenser coils suspended above the base of the chiller. Under the coils will be the evaporator, compressors, and piping. Many of the control cabinets will be positioned on the end of the chiller, some will be centered in the long side. Some chiller controls are in separate cabinets from the high voltage, while others aren't. These seems to come down to manufacturer preference. There are options to use remote evaporators or remote condensers. This goes back to their versatility per the application.
