Explore fundamentals of mechanical ventilation fans: how air movement scales with speed, power and efficiency, with examples and a survey of axial, centrifugal, cross-flow, and tangential fans.
Explore diffusers and how they diffuse and create effects using an HPLC system, including restricted air and the combat effect, with notes on suspended ceilings.
Calculate cooling loads, select a techno-economic system, and design air and water distribution, considering space, ambient conditions, occupancy, lighting, sun exposure, and utility availability.
Explore duct and accessories fabrication, including rectangular, round, and linear diffusers, bypass chambers, and compare axial and duplex flow types for kitchen, toilets, basement, chemical industry, and farm.
Analyze the cooling load arising from sensible and latent heat gains, including external and internal sources, and methods to size cooling coils and refrigeration systems.
Apply energy balance to compute cooling load from external and internal sensible gains and solar gains, using u-value and window area to determine required cooling capacity.
Linear diffusers in a wave system cause comfort problems; use deflection plates and adjust blades during balancing, and require multiple duct connections for four-foot sections to ensure even air distribution.
Discover ancillaries for hvac systems, from flexible connectors and sound attenuators to sand traps, intakes, dampers, diffusers, grills, bellmouths, and exhaust and toilet extractors, plus fan coil and split systems.
