Residential vs. Commercial systems • Course focus was on HVAC equipment that is used in both: residential and commercial systems • Emphasize on the application in commercial systems

Commercial HVAC Systems Multi zone Single zone CAV With and without humidity control VAV With and Dual without duct reheaters This is not the complete list ! CAV Dual With reheaters duct DOAS with fan coils or radiant ceilings All Hydroinic that relay on infiltration DOAS with fan coils

Typical Components in Commercial systems • • • Constant operation Outdoor air supply Two fans (supply and return) Multizone system Control …. .

Residential System

Course objectives • • • Apply fundamental physical principles to HVAC design Describe and size each component in an HVAC system Design HVAC systems based on manufacturer’s datasheets Contrast residential systems with commercial systems and use appropriate design techniques for each type of system Solve HVAC design problems with high-quality references
