CO2 vs. ammoniakki -vertailulaskuri

Vertaile teollista CO2- ja ammoniakkijäähdytystä samalla teholla, ilmastolla ja tariffilla. Tulokset sisältävät suuntaa antavan CAPEXin, vuotuisen energia- ja huoltokustannuksen sekä 10 vuoden kokonaiskustannuksen (TCO).

Ei sisällä turvallisuus- ja vaatimustenmukaisuussuunnittelua, konehuonetöitä, lupia, lämmöntalteenottohyvitystä tai paikallisia työvoimakustannuksia — nämä voivat muuttaa lopputulosta.

Pyydä toimittajia tarjoamaan molemmat kylmäaineet samalla teholla ja rajaehdoilla — ColdMatch rakentaa tarjouspyynnön niin, että vertailu on reilu.

Calculation method

  1. 1. Kausittainen COP = käyttökohteen COP (3,1 kylmä · 1,9 pakaste · 1,4 pikapakastus) ÷ ilmastokerroin (CO₂ 0,94–1,24 · NH₃ 1,00–1,06)
  2. 2. Kompressoriteho (kW) = jäähdytysteho ÷ COP
  3. 3. Vuotuinen energia = kompressorin kW × käyttötunnit × tariffi
  4. 4. Huolto = CAPEX × 3,5 % (CO₂) tai 4,5 % (NH₃)
  5. 5. 10 vuoden TCO = CAPEX + 10 × (energia + huolto)

Laskettu kW:na. Imperiaalinen: 1 kW = 3 412 BTU/h = 0,284 TR; kompressorin akseliteho 1 kW = 1,34 hv.

Worked example

600 kW pakastevarasto lämpimässä ilmastossa (huippu ~38 °C), 6 000 käyttötuntia.

Inputs

  • • Teho 600 kW (171 TR · 2,05 miljoonaa BTU/h)
  • • Pakasteen COP 1,9
  • • Lämmin: CO₂ ×1,12 · NH₃ ×1,03

Calculation

  • • CO₂ COP = 1,9 ÷ 1,12 = 1,70 → 354 kW → 2,12 GWh/v
  • • NH₃ COP = 1,9 ÷ 1,03 = 1,84 → 325 kW → 1,95 GWh/v

Ammoniakki kuluttaa n. 8 % vähemmän energiaa tässä ilmastossa; viileissä ilmastoissa CO₂-rasite katoaa ja ero kääntyy.

Limitations

  • • Ilmastorasitukset ovat kausittaisia keskiarvoja; rinnakkaispuristus, ejektorit tai adiabaattiset kaasujäähdyttimet pienentävät CO₂-rasitetta kuumissa ilmastoissa.
  • • Turvallisuusvyöhykkeet, täyttörajat sekä konehuone- ja lupakustannukset vaihtelevat maittain eikä niitä ole eritelty.
  • • Lämmöntalteenoton arvoa (usein merkittävä CO₂:lle) ei ole hyvitetty.

Ostajien kysymykset

Onko CO2 vai ammoniakki parempi teolliseen jäähdytykseen?
Kumpikaan ei ole yleisesti parempi. Ammoniakki on yleensä tehokkaampi suurilla tehoilla ja kuumissa ilmastoissa, kun taas CO2 välttää myrkyllisyysrajoitukset, sopii pienempiin konehuoneisiin ja toimii hyvin viileissä ja lauhkeissa ilmastoissa, etenkin rinnakkaispuristuksella. Teho, ilmasto, sijoitussäännöt ja huoltotaidot ratkaisevat.
Miksi ilmasto vaikuttaa niin paljon CO2:een?
CO2-transkriittiset järjestelmät menettävät hyötysuhdetta kriittisen pisteen yläpuolella, joten korkeampi ympäristölämpötila lisää energiankulutusta, ellei käytetä rinnakkaispuristusta, ejektoreja tai adiabaattisia kaasujäähdyttimiä. Kuumissa ilmastoissa kaskadijärjestelmä tai ammoniakkilaitos voittaa usein energian osalta.
Mitä tähän vertailuun ei sisälly?
Turvallisuus- ja vaatimustenmukaisuussuunnittelu, konehuoneen rakentaminen, luvat, vakuutuserot, käyttäjien koulutus, lämmöntalteenottohyvitykset ja paikalliset työvoimakustannukset. Nämä voivat muuttaa lopputulosta ja toimittajien tulee hinnoitella ne kohdekohtaisesti.
Voiko ColdMatch suositella kylmäainetta?
ColdMatch on kylmäaineneutraali. Autamme rakentamaan tarjouspyynnön, jossa toimittajia pyydetään tarjoamaan molemmat vaihtoehdot samalla teholla, oletuksilla ja rajaehdoilla, jotta voit vertailla niitä näyttöön, ei mieltymykseen perustuen.
