Left untreated the open loop can scale corrode and provide an encouraging environment for biological growth.
Water cooled air conditioner system.
Chilled water is circulated through a water coil equipped air handler to cool the living space and at the same time heat is absorbed from the air and.
Although the release of water is controlled water cooled air conditioners are still more expensive to run than traditional split air conditioners.
However if the unit is inside then the hot air will need an exhaust duct or fan that leads outdoors.
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.
Instead of circulating air through 18 inch air ducts chilled water is circulated through one inch pipes which fit easily into very tight spaces.
How water cooled air conditioning systems work.
Water cooled air conditioner is also called water cooled condenser as its function is to reject the heat that was absorbed by the refrigerant in the evaporator.
Air cooled systems remove heat from the unit by pushing it into the air.
Water cooled air conditioners however are plumbed directly into your mains water supply and use cold water to cool the system via internal pipes.
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.
