How to calculate cold room volume
Calculate internal cubic metres and understand the difference between room volume, airflow and refrigeration capacity.

Measure the internal dimensions
For a rectangular room, multiply internal width, depth and height. External dimensions include the panel thickness and produce a different volume.
An internal space measuring 2 m by 3 m with a height of 2.5 m has a volume of 15 m³. Use metres for every dimension.
Handle an irregular shape
Divide an irregular room into simpler volumes and add them together. Consider usable space and the storage arrangement when assessing air circulation.
The geometric measurement does not calculate required refrigeration capacity or performance with a given product load.
Keep the refrigeration units separate
Cubic metres measure volume. Cubic metres per hour measure airflow. Watts and kilowatts measure power. These quantities are not interchangeable.
More fan airflow alone does not make a refrigeration unit suitable for a larger room. The duty, capacity and operating conditions must also match.
Move from volume to a first selection
Combine internal volume with chilled or frozen storage, then check insulation, ambient conditions, products and door openings.
The home-page calculator helps you select a volume range in the catalogue. It does not replace a heat load calculation or guarantee refrigeration equipment sizing.
