Air-cooled chillers long have been the choice for system designers who are focused on simplicity and low cost. A system based on an air-cooled chiller usually is less expensive to install and easier to maintain than other types, such as water-cooled systems. On the other hand, these advantages typically have come at the expense of lower efficiency.
