1. 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; andadjusting the temperature of the fluid to cool or heat the air to a desired temperature, whereinthe 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, andthe coil assembly of the first module and the coil assembly of the second module are in series fluidic communication.2. The method of claim 1, wherein the step of adjusting the temperature of the fluid comprises passing the fluid through a source of recirculating fluid that is in series fluidic communication with the coil assemblies, wherein the source of recirculating fluid heats or cools the fluid to a predetermined temperature.3. The method of claim 1, further comprising drawing the first mass of air from a first room through the inlet of the first heat exchange module.4. The method of claim 3, further comprising directing at least a portion of the first mass of air into a second room.5. The method of claim 1, further comprising directing at least a portion of the first mass of air through the outlet of the first heat exchange module into a first room and thermostatically controlling the air temperature of the first room.6. The method of claim 5, wherein thermostatically controlling the air temperature of the first room comprises causing the fan to go on and off in response to a preset change in air temperature.7. The method of claim 1, further comprising adjusting the speed of the fan of the heat exchange module or the fan of the second heat exchange module.8. The method of claim 1, wherein the fan and the coil assembly are adapted and constructed to fit within a space no greater than 35 cm wide and 9.2 cm deep and having a predetermined height.9. The method of claim 1, wherein the air from the inlet is directed over a plurality of tangential fans.10. The method of claim 1, further comprising:directing a fluid through a coil assembly of a third heat exchange module and a fourth heat exchange module, wherein the coil assemblies of the third and fourth heat exchange modules are in series fluidic communication with one another and wherein the coil assemblies of the third and fourth heat exchange modules are in parallel fluidic communication with the coil assemblies of the first and second heat exchange modules.
