Abstract:
A method of adjusting air temperature, said method comprising the steps of:directing a first mass of air from an inlet of a first heat exchange module, over a coil assembly, to an outlet of the first heat exchange module using a tangential fan adapted and constructed to rotate about a vertically-oriented axis; simultaneously directing a second mass of air from an inlet of a second heat exchange module, over a coil assembly, to outlet of the second heat exchange module using a tangential fan adapted and constructed to rotate about a vertically-oriented axis; directing a fluid through the coil assembly of the first heat exchange module and the coil assembly of the second exchange module; and adjusting the temperature of the fluid to cool or heat the air to a desired temperature, wherein the coil assembly of the first module provides thermal communication between the first mass of air and the fluid and the coil assembly of the second module provides thermal communication between the second mass of air and the fluid, and the coil assembly of the first module and the coil assembly of the second module are in series fluidic communication.
