Energy-efficient industrial refrigeration plant

Planningstool

Calculator: CO2- en ammoniakkoeling vergelijken

Vergelijk industriële CO2- en ammoniakkoeling bij hetzelfde koelvermogen, klimaat en stroomtarief. Bereken indicatieve CAPEX, jaarlijkse energie- en onderhoudskosten en totale eigendomskosten over 10 jaar.

Exclusief engineering voor veiligheid en naleving van regelgeving, werkzaamheden aan de machinekamer, vergunningen, baten uit warmteterugwinning en lokale arbeidskosten — deze kunnen allemaal de uitkomst beïnvloeden.

Vraag leveranciers om beide koudemiddelen aan te bieden bij identiek koelvermogen en identieke randvoorwaarden — ColdMatch structureert de offerteaanvraag voor een eerlijke vergelijking.

Estimates Only: This calculator is provided for general informational purposes only. Results are approximate and may contain errors, omissions, or outdated information. They do not constitute legal, financial, engineering, tax, technical, or professional advice.

Calculation method

  1. 1. Seasonal COP = application COP (3.1 chilled · 1.9 frozen · 1.4 blast) ÷ climate penalty (CO₂ 0.94–1.24 · NH₃ 1.00–1.06)
  2. 2. Compressor power (kW) = refrigeration duty ÷ COP
  3. 3. Annual energy = compressor kW × run hours × tariff
  4. 4. Maintenance = capex × 3.5% (CO₂) or 4.5% (NH₃)
  5. 5. 10-year TCO = capex + 10 × (energy + maintenance)

Berekend in kW. Imperiale eenheden: 1 kW = 3,412 BTU/h = 0.284 TR; compressor-asvermogen 1 kW = 1.34 hp.

Worked example

Diepvriesinstallatie van 600 kW in een warm klimaat (piek ~38 °C), 6,000 bedrijfsuren.

Inputs

  • • Koelvermogen 600 kW (171 TR · 2.05 miljoen BTU/h)
  • • COP voor diepvriesopslag 1.9
  • • Warm: CO₂ ×1.12 · NH₃ ×1.03

Calculation

  • • CO₂ COP = 1.9 ÷ 1.12 = 1.70 → 354 kW → 2.12 GWh/yr
  • • NH₃ COP = 1.9 ÷ 1.03 = 1.84 → 325 kW → 1.95 GWh/yr

Ammoniak verbruikt in dit klimaat ≈ 8% minder energie; in koele klimaten verdwijnt het rendementsnadeel van CO₂ en keert het verschil om.

Limitations

  • • De klimaatgebonden rendementsverliezen zijn seizoensgemiddelden; parallelcompressie, ejectoren of adiabatische gaskoelers beperken het rendementsnadeel van CO₂ in hete klimaten.
  • • Veiligheidszonering, vulhoeveelheidslimieten en kosten voor machinekamers en vergunningen verschillen per land en zijn niet afzonderlijk opgenomen.
  • • De waarde van warmteterugwinning (vaak aanzienlijk bij CO₂) is niet meegerekend.

Vragen van inkopers

Is CO2 of ammoniak beter voor industriële koeling?
Geen van beide is altijd beter. Ammoniak is doorgaans efficiënter bij grote koelvermogens en in hete klimaten. CO2 vermijdt beperkingen vanwege toxiciteit, is geschikt voor kleinere machinekamers en presteert goed in koele en gematigde klimaten, vooral met parallelcompressie. Het koelvermogen, het klimaat, de locatievoorschriften en de beschikbare onderhoudsexpertise bepalen de keuze.
Waarom is het klimaat zo belangrijk voor CO2?
Transkritische CO2-systemen verliezen rendement boven het kritische punt. Hogere omgevingstemperaturen verhogen daardoor het energieverbruik, tenzij parallelcompressie, ejectoren of adiabatische gaskoelers worden toegepast. In hete klimaten verbruikt een cascadesysteem of ammoniakinstallatie vaak minder energie.
Wat is niet inbegrepen in deze vergelijking?
Engineering voor veiligheid en naleving van regelgeving, bouw van de machinekamer, vergunningen, verschillen in verzekeringskosten, opleiding van bedieningspersoneel, baten uit warmteterugwinning en lokale arbeidskosten. Deze factoren kunnen de uitkomst beïnvloeden en moeten door leveranciers voor uw specifieke locatie worden begroot.
Kan ColdMatch een koudemiddel aanbevelen?
ColdMatch is koudemiddelneutraal. We helpen een offerteaanvraag op te stellen waarin leveranciers beide opties aanbieden bij hetzelfde koelvermogen, dezelfde aannames en dezelfde randvoorwaarden. Zo vergelijkt u op basis van gegevens in plaats van voorkeur.
