Governing Formula:
Q_total = Q_transmission + Q_product + Q_internal + Q_air_infiltration; Safety Factor = 10%
Pune Field Notes & Environmental Standards:

Calibrated for PUF insulated panels (50mm, 100mm, 150mm) and Pune dairy/pharma storage standards.

Technical Engineering Guide & Field Diagnostic Practices

Walk-in cold rooms require rigorous heat load calculation accounting for wall transmission through PUF panels, daily product loading enthalpy reduction, respiration heat, door openings, and evaporator defrost cycles.
