a.To size the refrigerant lines
b.To establish total equipment capacity for the whole structure
c.To determine duct insulation R-value
d.To calculate the gas meter size
Giải thích
A block (whole-house) load establishes the total heating and cooling capacity the equipment must provide. A room-by-room load then distributes that capacity to size individual ducts and registers. Both are needed for a complete design.
