Load & DesignCâu 22 / 110
What is the main benefit of properly sizing equipment to a load calculation rather than oversizing?
a.Faster refrigerant charging
b.Better humidity control, comfort, and energy efficiency
c.Elimination of the need for a permit
d.Higher supply air velocity
Giải thích
Right-sized equipment runs longer, steadier cycles that dehumidify effectively and hold temperature evenly, improving comfort and efficiency. Oversizing wastes energy through short cycling and leaves the space humid. This aligns with Title 24 efficiency goals.
