Closed Loop Flat Type Copper Tube Aluminum Fin Dry Cooler Systems
How is closed-loop dry cooling system?
The strength of a closed-loop dry cooling system is that the unit
is very simple and relatively easy to install. The energy
requirements are relatively low and are easily controlled.
Maintenance is normally low requiring only periodic inspection,
lubrication, and testing of the fluid.
The best location for the fluid cooler is usually on the roof
because it requires free clear air to work efficiently.
However, the coolant must also have some kind of glycol to prevent
freezing if your location has a designed dry bulb in the winter
that dips below freezing. If the location is very cold, the
concentration of glycol may need to be significant to prevent
freezing. Glycol concentrations increasingly begin to reduce the
rate of heat transfer.
The weakness of a closed-loop dry cooling system is that it is
dependent on the atmospheric dry bulb. For example, if your
location’s design dry bulb is 100F in the summer and your equipment
requires 90F coolant, while the system can only supply around 105F
to 110F coolant to the load. In this case, you would need
supplemental cooling to get the coolant temperatures down to 90 F.
