HVAC Optimization with Cold Air Distribution

COURSE NO: M02-026
HVAC Optimization with Cold Air Distribution
Course Highlights

This online engineering PDH course outlines the application considerations for the successful design, installation and operation of the cold air HVAC system.


The 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 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.


Cold air production and distribution is not straight forward and requires more attention to details during 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 PDH online course is intended for mechanical, chemical & process engineers, system design engineers working in power, oil & gas, chemical, metal & mining, manufacturing and engineering industries, energy auditors, operational and maintenance personnel who are involved in the planning, design and operation of HVAC systems.
