This course develops the student’s core understanding of how energy is used by all HVAC systems, regardless of how they are applied, and how to reduce energy use. Information covered in class includes basic analysis of energy used to move fluids with fans and pumps through resistances, energy to change the thermal state of a fluid with heating / cooling / humidity changes, and auxiliary and prime mover losses. It also covers a simple, taxonomic approach to universal methods of analyzing energy savings potential. Energy use and conservation in common systems and equipment will be reviewed. Finally, the course offers a practicum with attendee’s actual systems and equipment discussed in an open forum. Course includes case studies and low cost/no cost ideas.
