Beregn kjøleeffekt – kW, BTU/t og tonn kulde
Beregn nødvendig kjøleeffekt i kW, BTU/t og tonn kulde for et kjølerom eller en frysetunnel. Basert på romvolum, temperaturklasse og klima.

Nødvendig kjøleeffekt omdanner romets totale varmelast til kW, BTU/t og tonn kulde: 1 kW = 3 412 BTU/t = 0,284 TR. Typiske veiledende laster er 40–60 W/m³ for kjølte rom (0 til +4 °C), 60–90 W/m³ for fryselager (−18 til −25 °C) og 150–400 W/m³ for spesialfrysing, før 10–20 % sikkerhetsmargin.
Effekt (kW) = volum (m³) × lastfaktor (W/m³) ÷ 1000 × sikkerhetsfaktor · BTU/t = kW × 3412 · TR = kW ÷ 3,517

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 countryAI 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.
Ofte stilte spørsmål
Hvordan beregner jeg nødvendig kjøleeffekt?
Grovtilnærming: romvolum × typisk lastfaktor per temperaturklasse — 40–60 W/m³ for kjølte rom, 60–90 W/m³ for fryselager og 150–400 W/m³ for spesialfrysing — pluss 10–20 % sikkerhetsmargin. Verktøyet viser resultatet samtidig i kW, BTU/t og tonn kulde (1 tonn kulde = 3,517 kW).
Hvilken sikkerhetsmargin bør brukes?
15–20 % er standard; for legemidler bør man i tillegg legge til N+1-redundans.
Har utetemperaturen betydning?
Varme/tropiske klima kan øke designlasten med 20–30 % sammenlignet med temperert klima.
Hva regnes som typisk W/m³ for ulike romtyper?
Grovt sett 40–60 W/m³ for kjølte rom (0 til +4 °C), 60–90 W/m³ for fryselager (−18 til −25 °C) og 150–400 W/m³ for spesialfrysing, før sikkerhetsmargin.
Hvordan bruker jeg resultatet i en forespørsel om anlegg?
Ta kW-, BTU- og TR-verdiene sammen med romvolum og temperaturklasse inn i RFQ-verktøyet. ColdMatch gjennomgår notatet manuelt før eventuell leverandørintroduksjon.
