An introduction to HVAC system design — how engineers perform load calculations, select equipment, and design distribution systems for commercial and residential buildings.
An oversized HVAC system short-cycles — it turns on and off rapidly without running long enough to dehumidify the air or distribute conditioned air evenly. An undersized system runs constantly and still can't maintain comfort on peak design days. Correct sizing requires a proper load calculation, not rules of thumb like "400 sq ft per ton."
