Drying-System Balance (Installed Dehu vs Evaporation Load)
Checks whether the installed dehumidification keeps up with the estimated evaporation load.
Example
You enter
- Evaporation load (pints/day, from evaporation-load) 200
- Installed dehu capacity (pints/day; field, not AHAM) 260
- Target capacity-to-load ratio 1.2
You get
- Balance 60 ppd
- Capacity-to-load ratio 1.3
Details, formula, and sources
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.
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.
Closes the loop between the evaporation-load and dehumidifier tiles: a balanced system keeps installed dehumidification at or above the evaporation load with margin.
Estimate. AHJ and licensed professional govern.
