Overview
Credit: 2 PDH
Length: 21 pages
A cold air distribution system refers to supplying air at low temperatures of around 42 to 50°F instead of the customary 55°F. Cooling supply air below 55°F reduces the supply air volume dramatically, thereby reducing the first cost of the air-handling equipment and recurring energy costs. Humidity levels can be lower - within the range of 40 to 50%, resulting in improved air quality, comfort and productivity. The physical size of HVAC equipment is smaller, resulting in smaller mechanical rooms, less dead space above ceilings, and more room for occupants.
Nonetheless, cold air production and distribution is not straight forward and requires more attention to details during the design phase. This includes detailing to prevent condensation or sweating on the cold surfaces, dumping of cold air and careful selection of ceiling diffusers. Duct leakage is more of a concern and coil selection is based on parameters that are different from conventional designs.
This 2-hour course outlines the application considerations for the successful design, installation and operation of a cold air HVAC system. This course is aimed at mechanical and HVAC engineers, architects, building designers, energy auditors, operational and maintenance personnel, sales and marketing personnel, and others.
