Blueprint: Evaporative Cooling Store for a Village Produce Market — Build Specification

DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. Build specification for a 3.0 cubic metre double-wall brick-and-charcoal evaporative cooling store for a village produce market, drawn from the source paper: William Alexander Aldred, 'An Evaporative Cooling Store for a Village Produce Market: Design, Simulated Performance Across Climates, and the Humidity Failure Line', DOI: 10.5281/zenodo.24108663. The blueprint specifies internal dimensions 2.0 m by 1.25 m by 1.20 m, usable storage 2.4 cubic metres and a 500 kg full load; the approximately 0.10 m charcoal cavity (0.828 cubic metres of coarse charcoal fill, derived), the gravity drip water system (6.7 litres per day evaporated at the arid design point, about 10.0 litres per day supplied at the source paper's 1.5 allowance), materials with quantities, assembly sequence, loading and operating procedure, tolerances, failure modes and maintenance. Simulated performance: holds 24.6 degrees Celsius inside in 40 degrees Celsius arid heat at 15 percent relative humidity, and stops being useful above 61.5 percent ambient relative humidity at 35 degrees Celsius. All performance figures are simulated, not measured, and no store built to this blueprint has been tested.
