An electric heater adapted to be used as a space heater or to be mounted over the discharge end of a hot air duct to diffuse air flowing into a room from the hot air duct and to heat the air in the room. The electric heater includes a housing adapted to be positioned over the ...
velocity at the peripheral part of the inner surface of the duct higher than that at the center part thereof and providing a ventilation port and several dusters having a proper length to the bottom part of a header so as to form large turbulent air in the downstream part of the header. ...
A fully self contained, in-line humidity control system for a forced air HVAC system. The system is designed to be integrated into the duct system of an existing or new installation forced air HVAC system such that the environment throughout a structure may be dehumidified by a central ...
Have the ducts and registers cleaned. Although it's rare for dust alone to actually reduce airflow, it's been known to happen. While it's possible to do this work yourself, duct cleaning from a professional service isn't very expensive, and it's much easier than doing it yoursel...

A filter assembly for mounting over an opening at an end of a forced air system duct, such as a cold air return. The filter assembly is designed to replace an existing louvered grill covering. The filter assembly is dimensioned which substantially retains the shape and appearance of the ...
air duct sealing device of the forced draft circular cooler, which comprises a lower circular fixed air duct of the forced draft circular cooler, an upper circular movable air duct, and a sealing device arranged between the upper circular movable air duct and the lower circular fixed air duct....
Using CFD, the paper deals with a simulation of all phenomena related to forced-air duct fitted with a fan, with the emphasis on unit aerodynamic resistance and untight air ducts. We created a 3-dimentional model of the system including perforations simulating untightens in ...
