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.
