Refrigeration Capacity Sizing & Equipment Selection Guide
The 6 critical engineering inputs required to size condensing units and evaporators accurately: dimensions, product entry temp, daily turnover, and ambient climate.
1. More Important Than Room Volume: Daily Product Turnover & Entry Temperature
A 100 m³ room receiving 1 ton/day of pre-cooled +6°C product requires one-third the cooling capacity of the same room receiving 8 tons/day of warm +28°C field-harvested produce.

Preventing product dehydration, ensuring uniform pallet temperatures, and maintaining draft-free working halls depend on selecting the right evaporator geometry and fin spacing (4 / 6 / 8 / 10 / 12 mm).
Frequently Asked Engineering & Supply Questions
Frequently asked technical questions regarding cold room doors, panel thickness selection, thermal sealing details, and turnkey project workflows.
C21 Can refrigeration capacity be calculated based solely on room volume (m³)?
No. Room volume alone only provides a preliminary estimate. Actual cooling load depends on daily product intake tonnage, product entry temperature, specific heat, pull-down time, ambient climate, and door opening frequency.
C22 Is a frozen storage room (-18°C) the same as a blast freezer room (-35°C / -40°C)?
Definitely not. A frozen storage room (-18°C) maintains products that are already frozen. A blast freezer (-35°C / -40°C) uses high-velocity airflow and high refrigeration capacity to rapidly pull down core product temperature to -18°C within hours.
C23 Should we choose individual split condensing units or a central multi-compressor rack system?
For facilities with 1 to 4 rooms or where independent redundancy per room is desired, industrial split units (R01) are cost-effective. For large multi-room logistics hubs and food factories, central multi-compressor racks (R02) offer superior energy efficiency and capacity modulation.
C24 Why is fin spacing critical when selecting cold room unit coolers (evaporators)?
While 4–6 mm fin spacing works for positive (+2/+8°C) chillers, sub-zero freezers (-18°C) require 7–8 mm and blast freezers require 10–12 mm wide fin spacing to prevent rapid frost bridging and airflow blockage.
C25 Why is remote temperature monitoring and alarm data-logging (R04) necessary?
Digital data-logging and mobile alarm panels protect high-value inventory against power outages, open doors, or defrost faults while providing mandatory historical temperature audit trails for food safety and GDP inspections.
C26 Why should an ante-room (precooling / buffer corridor) be included in cold store design?
Opening a -18°C or +2°C chamber directly to +35°C outdoor air causes severe moisture ingress, icy floors, and high power consumption. A temperature-controlled +8/+12°C ante-room acts as a thermal airlock.
