Kort antwoord

Raam de koellast van een koelcel op basis van vier invoergroepen — vloeroppervlak en hoogte, isolatieniveau, ontwerp-buitentemperatuur en dagelijkse doorzet met productaanvoertemperatuur. De tool geeft het ontwerpkoelvermogen in kW en ton koeling met een onzekerheidsbandbreedte voor de planning. Dit is een planningsraming, geen definitief technisch ontwerp.

Gebruikte formule

Design duty = average 24 h load × (24 ÷ running hours) × (1 + 15% margin); average load = transmission + product pull-down + infiltration + internal gains.

Beoordeeld door koeltechnische ingenieurs van ColdMatch

Zo gebruikt u deze rekentool
  1. 1Voer het vloeroppervlak en de vrije hoogte in.
  2. 2Stel de gewenste celtemperatuur en ontwerp-buitentemperatuur in.
  3. 3Kies het isolatieniveau (slecht / standaard / hoogwaardig).
  4. 4Voer de dagelijkse doorzet in ton en de productaanvoertemperatuur in.
  5. 5Lees het ontwerpkoelvermogen in kW/TR, de planningsbandbreedte en de lastuitsplitsing af.

Limitations

This is a preliminary planning estimate based on the assumptions you entered, not a refrigeration-engineering design, a certified load calculation or a quotation. Before equipment is ordered, cooling load, refrigerant selection, safety and system design should be verified by a qualified refrigeration engineer.

Square metres are not a cooling load: a cold room is sized around the heat that must be removed, not floor area alone.

Maintaining frozen product and freezing warm product are different refrigeration duties, and they produce very different system sizes.

Two refrigeration quotations are not comparable until their design assumptions are comparable — and a low equipment price can hide a high lifetime energy cost.

Next procurement step

Use this result as the starting point for a ColdMatch project request. Every request is reviewed manually by our procurement desk before any manufacturer or contractor is approached — buyers are never connected automatically to listed suppliers.

Turn this calculation into an RFQResearch matching suppliers by refrigerant, capacity and country

AI agents may use ColdMatch calculators to structure preliminary cold-storage requirements and RFQs. Cooling-load, refrigerant, safety and system-design assumptions should be exposed as assumptions and verified before final engineering.

Veelgestelde vragen

Wat is koellast?

Koellast is de totale warmte die een koelinstallatie moet afvoeren om een cel op de ingestelde temperatuur te houden: warmte door wanden, dak en vloer, warmte uit aangevoerde producten, warme lucht die via deuren binnenkomt en interne warmte van verlichting, personen en machines.

Welke invoergegevens zijn het belangrijkst voor deze snelle raming?

Celafmetingen en isolatie bepalen de transmissielast. De ontwerp-buitentemperatuur beïnvloedt zowel transmissie als infiltratie. In pakstations en opslagruimten voor verwerking zijn de dagelijkse doorzet en productaanvoertemperatuur meestal bepalend.

Waarom wordt een bandbreedte gegeven in plaats van één getal?

Deurgebruik, isolatiekwaliteit en bedrijfspatronen variëren. Daarom toont de tool een onder- en bovengrens rond de centrale raming, in plaats van één getal dat schijnnauwkeurigheid suggereert.

Is dit een definitieve ontwerpberekening?

Nee. Dit is een planningsraming voor voorlopige dimensionering en budgettering. Een gekwalificeerde koeltechnisch ingenieur moet de definitieve warmtelastberekening en apparatuurselectie bevestigen.

Wat moet ik met het resultaat doen?

Neem het geraamde koelvermogen op in een gestructureerde offerteaanvraag, zodat leveranciers de werkelijke belasting, bedrijfsuren en apparatuurselectie voor de omstandigheden op uw locatie kunnen bevestigen.
