Air Pollution Control Ventilation Equipment .... 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. In this course the student will learn about  more...

Laboratories Best Practices Manifolding Exhaust ...ties when compared to separately ducted, multiple exhaust fans. A manifolded system also offers a number of benefits, including increased fume dilution, enhanced personnel safety, augmented redundancy and improved design flexibility. A holistic, team-based approach is important when determining the design and appropriateness of a manifolded exhaust system. Design decisions regarding fan type,  more...

Laboratories Best Practices Energy Recovery ...oling energy needed to condition this air, as well as the fan energy needed to move it, is 5 to 10 times greater than the amount of energy used in most offices for those purposes. Heating and cooling systems can be downsized when energy recovery is used, because energy recovery systems reduce peak heating and cooling requirements In this course the student will learn to better understand  more...

Laboratories Best Practices Minimizing Reheat ...minate the use of reheat energy, including dual-duct-dual-fan systems, fan coil systems, zone cooling and heating coils, and radiant cooling. Continuous commissioning is also discussed as an important tool in minimizing simultaneous heating and cooling. The student is expected to read and review the material contained in the Laboratories For The 21st Century: Best Practices Guide ?  more...

HVAC - Equipment and Systems ...ation baseboard units, air handling units, unitary units, fan coil units and their components ?Air Distribution Ductwork ? Provides an overview of air movement, components of air distribution systems, duct classification on velocity, pressure, shape and materials ?Air Distribution Equipment & Accessories ? Provides an overview of air delivery devices such as registers, grilles and diffusers.  more...

Fans for Livestock Buildings ...iple of stepped ventilation using several different-sized fans is explained and compared with control schemes using two-speed, multispeed or variable-speed fans. This plan also discusses other important considerations in choosing fans and controls for ventilating modern livestock and poultry buildings. The student is expected to read and review the material contained in the Selecting Fans For  more...

Fan Coil Basics - Titus ...Fan coil units are products that have been around for years; however, there has been a growing interest in the use of these products for a variety of reasons. Fan coil units can provide zone control of heating and cooling in a manner that matches the zone load. For fan coil products, the typical application characteristics are similar to multi-family residential building. For these structures,  more...

Room Fires Positive Ventilation ...fans to pressurize a structure prior to suppressing a fire. This pressurization or positive pressure ventilation tactic can assist in the venting of smoke and high temperature combustion products and make attacking the fire easier than without positive pressure ventilation. However, this tactic also provides additional oxygen to the fire and can increase the rate of heat and energy being  more...

Duct Thermal Performance ...iencies, duct performance principles such as air leakage, fan performance and heat transfer. In addition the student will gain an understanding of the California Title 24 Duct Systems Compliance Path. The student is expected to read and review the material contained in Duct Thermal Performance Models for Large Commercial Buildings, LBNL-53410 October 2003. The student must take a  more...

Terminal Units ...ging from fairly common single duct boxes to more complex fan terminal units with special IAQ inlet controls. In this course the student will learn some of the basics of selection and applications of terminal units including installation considerations, controls, sizing and types of units. The student is expected to read and review the material contained in the Titus Product Catalog  more...

Air Conditioning Systems ...system of mechanical components - usually a compressor, a fan, condenser coil, evaporator coil and a chemical refrigerant - extract heat from indoor air and transfers it outside, leaving the cooled indoor air to be re-circulated. The cleaning function of air conditioners is performed by filters. Diverse geographical and operating conditions require considerably different types of air  more...

Industrial Fan Fundamentals ...fan for a particular application is dependent upon many factors. Initial cost, efficiency, operating and maintenance costs, speed, materials, space constraints, flow rate, pressure, temperature, cleanliness of the product and the range of operating conditions are all considerations in the selection of a fan and driver. Improper selection of the fan/driver can result in higher operating and  more...
