REFR 114 HVACR Year 1 Week 4
Apprentices will use the Pythagorean Theorem to solve for angles and complete basic piping offsets. They will draw increasingly complex wiring diagrams, including split phase and shaded pole induction motors. They will apply air and water flow calculations to understand heat transfer, and load formulas to solve for BTUH. They will further apply these calculations to calculate specific areas and data in a built environment. They will plot air conditioning and refrigeration system using psychometric charts. They will continue brazing and oxy-fuel welding following progression charts. Finally, they will identify hazards to setting equipment.
