Duct Sizer (Size By Dimensions): Select this row to open the input form that allows you to specify duct dimensions and one of either airflow or velocity values to calculate duct friction loss and other values. See below for more details. Duct Sizer (Range of Duct Sizes): Select this row...
Three phase heaters are available in voltages from 208 to 600 Volts AC, for insertion into duct sizes ranging from 6” x 8” to 120” x 144” OPTIONAL FEATURES Circuit fusing under 48 Amps Insulated control panels (standard on plenum style heaters) ...
One of the common air filter sizes may work for your HVAC system. However, if your filter doesn't fit properly, here's how to measure it.
A genetic algorithm technique is used to design an HVAC air duct system with minimum life-cycle cost. The approach has the capability to incorporate standard (discrete) duct sizes, variable time-of-day operating conditions and variable time-of-day utility rates. An example is used to illustrate...

TheHVAC Duct Sizermodule allows you to quickly size one HVAC duct run and a range of duct sizes. You can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters). The results include both the...

Equipment rooms: since the total mechanical and electrical space requirements range between 4 and 9% of the gross building area. It is preferable to be centrally located in the building to reduce the long duct, pipe, and conduit runs and sizes, to simplify shaft layouts, and centralized mainte...
Manual HVAC fire damper FH-70, installed in the ventilation or air-conditioning systems, usually it is open, once a fire occurs, the gas temperature of the duct arrives at 70 degrees, and then the fuse protector will be fused and the damper...
