Water Based Shell Tube Air Cooler For The Air Handling Unit
A water-based shell-and-tube heat exchanger functions as a critical cooling or heating coil within an Air Handling Unit (AHU). It utilizes a bundle of tubes housed in a cylindrical shell-the water runs through the tubes while air passes across the outer surfaces to achieve precise space cooling or dehumidification.
How the Process Works
Tube Side: Chilled water (typically supplied by a central chiller plant or cooling tower system) flows through the internal metal tubes.
Shell Side: Warm building air (or outside ventilation air) is forced across the outside of the tubes using the AHU's supply fan.
Heat Transfer: Heat from the air is transferred to the cooler water via conduction, resulting in conditioned, cooled supply air entering your facility.
Key Benefits for AHUs
High Efficiency: The large surface area of tube bundles combined with internal baffles ensures maximum thermal transfer and turbulence.
High Pressure: Shell-and-tube coils are built to handle rigorous water pressures compared to standard finned-tube coils.
Robust Maintenance: These heat exchangers can be dismantled, allowing technicians to easily clean out scale or debris from the tubes.
