Drying-System Balance (Installed Dehu vs Evaporation Load)

Checks whether the installed dehumidification keeps up with the estimated evaporation load: the balance in pints/day, the capacity-to-load ratio against a target margin, and a balanced / no-margin / deficit verdict with the capacity to add. Closes the loop between evaporation-load and dehumidifier. Field capacity falls below the AHAM nameplate as the air dries; the restorer's daily monitoring and IICRC S500 govern.

Formula and source

balance_ppd = installed_ppd - evap_load_ppd; ratio = installed_ppd / evap_load_ppd; verdict from ratio against the target margin (default 1.2): >= margin balanced with margin, 1 to margin no margin, < 1 deficit (add margin x load - installed).

Balanced-drying-system principle, by name; ANSI/IICRC S500. The capacity-to-load comparison is a field-arithmetic identity, not edition-bound.
