How water cooled air conditioning systems work.
Air cooled versus water cooled system specs.
Left untreated the open loop can scale corrode and provide an encouraging environment for biological growth.
An air cooled condenser uses no water on site and requires no on site water treatment while a water cooled system of any size requires that the open loop be treated.
Once through water cooling system is applied in large centralized air conditioning installation in locations where sufficient cooling water is available such as those along the seafront of victoria.
