## What is PassiveCool Sim?

PassiveCool Sim is a passive evaporative cooling simulation tool built on wet-bulb thermodynamics, inspired by traditional cooling techniques passed down for centuries across the Middle East and North Africa (clay water coolers, pot-in-pot food coolers, wet pad walls, windcatchers, and more).

Core Features
- Local Simulation: Enter ambient temperature and humidity, wind speed, porous medium material and thickness, and inlet water temperature to instantly obtain theoretical wet-bulb temperature, outlet temperature, temperature drop, water consumption, and evaporative efficiency — all computed offline on your device
- Vector Performance Curves: Efficiency–wind speed and outlet temperature–wind speed curves drawn entirely in code, visualizing device characteristics at a glance
- Live & Historical Weather: Connects to OpenWeather to pull current conditions and auto-fill parameters, or look back at any historical date to simulate seasonal performance; all features remain fully usable manually without a network
- Project Management & Comparison: Save multiple device projects, then select 2–4 to generate side-by-side parameter and result tables with comparison curves
- Field Test Bias Analysis: Record on-site measurements and the app automatically recomputes theoretical values, reporting temperature/efficiency bias with likely causes
- Notes & Snapshots: Notes can be linked to projects and store parameter snapshots, reloadable into the simulator in one tap to reproduce conditions
- Consumables Estimation: Enter the device's effective face area to estimate porous material usage and reference tank capacity
- Case Library: 5 built-in traditional technique cases with vector structure diagrams; parameters import into the simulator with one tap
- Engineering Toolbox: Standalone quick calculators for dew point and wet-bulb temperature
- Units & Dark Mode: Freely switch between Celsius/Fahrenheit and Metric/Imperial; automatically follows the system's light and dark appearance

Data: All data is stored locally with one-tap backup export; location permission is used only to fetch weather on demand — never for background tracking.

All outputs in this app are theoretical simulation estimates, intended for learning and research reference only, and must not be used directly as a basis for construction.
