An industrial air conditioner unit can either be air-cooled or water-cooled.

In an air-cooled unit, a fan is used to circulate air over a refrigerant-cooled condenser coil. The hot air from the condenser is then exhausted outside the building. This type of unit is relatively simple, inexpensive and does not require a water supply. It is typically used in small to medium-sized industrial facilities where water resources are limited or not readily available.

In a water-cooled unit, a water pump circulates water over a refrigerant-cooled condenser coil. The hot water is then cooled in a cooling tower or a chiller before being recycled back to the condenser. This type of unit is more energy efficient and typically used in large industrial facilities where the cooling load is higher and a water source is readily available.

Both air-cooled and water-cooled units serve the same purpose of removing heat from the air in the building and cooling it. The choice between the two depends on the specific requirements of the facility and the available resources.
