Duct Bank Heating Calculations are Essential for Critical ...

layering your conduits within your duct bank to reduce the total heating effect. Fourier Law described the effects of heat transferred by conduction. The heat flux is proportional to the ratio of temperature over space. The air space within the conduit is the only area within a duct bank that does not conduct heat. In the air space convection

INTRODUCTION: HVAC BASICS

1. An outside air duct can be found either before the cooling coil or before the filters on the air handling unit, depending on the design. 2. A system may have multiple sets of filters to remove different levels of impurities. 3. If the outside air duct is before the cooling coil the filters may be located before the outside air damper or ...
