Data and code for "Second heat sink after feed-water recovery in closed-air open-water humidification-dehumidification desalination"

This record contains the model code, analysis archives, processed result tables, figure data and figures that accompany the manuscript "Second heat sink after feed-water recovery in closed-air open-water humidification-dehumidification desalination: a matched-hardware decision framework with net-water and electricity accounting" (manuscript in preparation for submission). The study is a steady-state, model-only comparison of a recovery-only closed-air open-water humidification-dehumidification (CAOW-HDH) cycle with the same cycle plus a second, independently cooled dehumidification coil under a matched hardware allowance. Contents:- 01_model_and_analysis_code: MATLAB model and the analysis, screening, branch-audit and site-sampling scripts, plus a post-processing script in Python.- 02_analysis_stages: code, inputs, result tables and logs of the analysis stages, in order.- 03_completion_extension: driver, logs and outputs of the completion run of eight sampled hours.- 04_excel_data_and_charts: Excel workbook with the plotted data and charts, and the scripts that build and check it.- 05_figures: manuscript figures and the graphical abstract (PNG, PDF, EMF, PPTX).- Supplementary tables, a map from the analysis stages to the manuscript (PHASE_TO_PAPER_MAP.md), SHA-256 integrity files and licence texts. Third-party weather, reanalysis and sea-surface-temperature data (TMYx, ERA5-Land, Open-Meteo) are not included; see EXCLUDED_THIRD_PARTY_DATA.md for sources and dates of retrieval. Code is released under the MIT licence and data, tables and figures under CC BY 4.0; see README.md for the scope of each. Files are under embargo until the date shown and will be released openly then.
