04Capstone Project

  1. ▶Capstone: Thermal Storage DiagnosticsHands-on: diagnose eight storage call-outs — sensible vs latent sizing, the cooling business case, the flat-tariff trap, stratification, standing losses, seasonal scale, charging schedules and PCM selection — then calculate, verify and prescribe the fix.30 min
