Air-cooled chillers adapt well to a wide range of operating conditions. They are easier to install, require less maintenance, and can be used in many applications. However, for the same cooling capacity, their material cost is usually higher compared to water-cooled models.
Water-cooled chillers are more suitable when there is a stable water supply, good water quality, and ambient temperatures below 45 °C. They generally offer better cooling performance, lower energy consumption, and quieter operation. Their overall cost can be slightly lower, but installation is more complex as they require a cooling tower and water pump. Cleaning and servicing the shell-and-tube condenser also calls for trained technicians.
