Load & Design第 1 / 110 题
In residential load calculations, what does an ACCA Manual J procedure primarily determine?
a.The size and gauge of supply ductwork
b.The heating and cooling loads of a building based on its construction and climate
c.The refrigerant charge required for the condenser
d.The electrical service size for the panel
解析
Manual J is the industry-standard residential load calculation method. It estimates the sensible and latent heating and cooling loads by accounting for construction, insulation, windows, orientation, infiltration, and local design temperatures. Equipment is then selected to match those calculated loads.
