Free Basic Cold Room Heat Load & Refrigeration Duty Calculator (Chill, Freeze & Blast):
Estimate coldroom volume and required refrigeration capacity (kW) for:
- Storage (Chill/Freezer): steady-state duty
- Cool-down: cooling product to setpoint over a chosen time
- Freeze / Blast Freeze: includes latent heat and sub-freezing pull-down
Just enter what you know—blank fields use sensible defaults (ambient 30 °C, typical U-values, 2 ACH, etc.).
