Air Pollution Control Ventilation Equipment ... most kinds of control devices. These are: (1) hoods, (2) ductwork, (3) stacks, and (4) fans. Together, these items comprise a ventilation system. A hood is used to capture the emissions at the source; ductwork, to convey them to the control device; a stack, to disperse them after they leave the device; and a fan, to provide the energy for moving them through the control system.

Improving the Efficiency of Duct Systems ...e student will learn some of the basics about residential ductwork supply and return systems. This course addresses both the energy and health impacts of residential duct installations. Retrofitting of existing residential duct systems is possible under the guidance of a professional; however, it is best to properly install the ductwork in new construction so that the system can operate at  more...

Ductwork - Exterior Exposed ...ed thermal losses depends directly on the location of the ductwork. For ducts located entirely within the conditioned space, any thermal losses go directly to the conditioned space. The greatest thermal losses and related energy penalties occur when ducts are located entirely outside of the building envelope. Factors affecting thermal losses and energy penalties of exterior ducts include  more...

UV Lamps in Air Circulating Ductwork ...ome of the basic issues related to UV disinfecting in air ductwork, including the installation parameters that impact the effectiveness of UV lights in air ductwork and considerations regarding the effectiveness of UV lights with respect to germicidal irradiation to deactivate viruses, mycloplasma, bacteria and fungi. The student is expected to read and review the material contained in  more...

Kitchen Makeup Air ...input are evaluated, hoods are located and specified, the ductwork size and routing are determined, and exhaust fans are specified to remove the proper volume of air. Unfortunately, much less time is usually dedicated to planning how the exhausted volume of air will be replaced, although an air balance schedule is commonly used to indicate the source and quantity of the makeup air. In this  more...
