Blueprint: Passive Medicine-Storage Cooling Cabinet — Build and Implementation Specification

Build and implementation specification for a passive medicine-storage cabinet with internal dimensions 0.60 x 0.60 x 1.00 m, 0.100 m polyurethane insulation, a 2.5 m2 radiative roof panel, an 80 kg water thermal store and a 0.5 m2 indirect evaporative jacket, computed to hold at or below 25 °C through a 40 °C peak day in dry air (23.84 °C maximum with evaporation) and in 26 of 48 swept climates, at a parts cost of 670 USD. DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT, NOT CLINICALLY TESTED. Blueprint for the design published as DOI 10.5281/zenodo.24109046.
