Healthcare facilities require uninterrupted potable and process water for sterile processing, dialysis and pharmaceutical compounding, yet one in four facilities worldwide operates without reliable on-site supply, and existing atmospheric water generation architectures fail to meet the operational envelope of healthcare deployment because single-pathway condensation systems exceed 0.78 kWh/L below 40 % relative humidity and metal-organic-framework sorption systems operate in batch cycles incompatible with continuous draw. A psychrometrically adaptive dual-pathway framework with fleet-level constrained optimization is developed and evaluated against this envelope, coupling vapor-compression refrigeration to a 60:40 silica-gel/zeolite-13X composite sorbent with condenser-to-regenerator heat recovery and a supervisory optimizer phasing regeneration cycle across modules through 200 Hz IEC 61850 GOOSE telemetry. Experimental evaluation on a four-module test array within a Weiss WK11-340/70 climatic chamber across five trial campaigns delivered 0.42 kWh/L specific electrical consumption at the 30 °C and 60 % relative humidity design point over 168 hours, 19.6 % regeneration electrical demand reduction, 0.21 bar peak manifold pressure deviation under hot-swap substitution at 75 % degraded-fleet demand, and 22.8 % lifecycle electrical cost reduction at 14.3 % capital premium.
