Grid breeze

Welcome to Grid Breeze – the high-performance, zero-permission thermal flow and HVAC computational matrix engineered specifically for refrigeration mechanics, ventilation engineers, cleanroom operators, and smart-home installers who require reliable environmental tracking entirely offline. Grid Breeze packs four specialized fluid dynamics and thermal flow calculation engines onto a clean, single-viewport dashboard panel. Profile duct velocity, estimate space cooling capacities, resolve relative humidity parameters, and compute air duct friction drops instantly without relying on active cellular networks or external telemetry data. 🔒 100% OFFLINE & PRIVATE (ZERO PERMISSIONS) Grid Breeze runs on a strict, local-first computing framework. The application deliberately excludes the Android Internet Permission (android.permission.INTERNET) from its manifest and requests zero hardware permissions. Your duct dimensions, airspeeds, ambient temperatures, and room volumes are processed entirely within volatile device system memory and never leave your hardware. 🚀 FOUR CORE THERMAL ENGINES 1. AIRFLOW VELOCITY & CFM PROFILER Calculate precise volumetric airflow parameters instantly. Input duct dimensions (rectangular or circular) and measured air velocity. The engine isolates total volumetric airflow rates in Cubic Feet per Minute (CFM) or cubic meters per hour. 2. THERMAL LOAD BTUh MATRIX Estimate indoor climate capacity demands accurately. Input target room volume, physical insulation quality tiers, and ambient-to-target temperature differentials. The engine models target thermal gain to determine estimated equipment capacity requirements in BTUh or Tons. 3. PSYCHROMETRIC RELATIVE HUMIDITY SCALER Evaluate ambient atmospheric conditions on-site. Input concurrent wet-bulb and dry-bulb temperature values. The engine computes relative humidity, moisture grain parameters, and enthalpy metrics without requiring internet-connected psychrometric charts. 4. FRICTION LOSS DUCT SIZER Optimize duct layout efficiency and fan selection. Input total duct run length, internal surface material roughness, and target airspeeds. The calculation engine estimates static pressure friction loss per 100 feet to prevent system airflow restriction. IMPORTANT NOTICE: Grid Breeze is a mathematical reference utility. All calculations are approximations based strictly on user-supplied manual inputs and standard thermodynamic principles. These outputs do not substitute for official Manual J/S/D engineering logs, certified air balancing reports, or state building safety inspections. The HVAC operator holds absolute responsibility for physical installations.
