Cold room cooling load calculator

Enter the room dimensions, panel thickness, stored product and temperatures; transmission, product, infiltration and internal loads are calculated separately and the required cooling capacity is given in kW.

Product

Stored product

Recommended storage 0 – 4 °C, relative humidity 85%; freezing point -1.5 °C.

Total stored product (kg)For respiration heat (fruit and vegetables); no effect for other productsDaily product intake (kg/day)Fresh intake to be cooled down to room temperatureProduct entering temperature (°C)Pull-down time (hours)Time allowed for the intake to reach room temperature
