Kompressorin mitoitus kylmälaitoksille

Arvioi moottoriteho, COP ja iskutilavuus kompressoreille, jotka käyttävät NH₃:a, transkriittistä CO₂:a, HFO-seoksia ja propaania.

Nopea vastaus

Kompressorin mitoitus perustuu höyrystimen tehoon kW:na ja käytön COP-arvoon: akseliteho ≈ jäähdytysteho ÷ COP. Tyypillinen COP on 3,5–5,0 kylmäkäytössä (−5 °C höyrystyminen) ja 1,4–2,2 pakastekäytössä (−35 °C). Ammoniakki (NH₃) antaa yleensä parhaan hyötysuhteen suurissa laitoksissa, kun taas CO₂ (R-744) sopii pienen täyttömäärän järjestelmiin ja kaskadijärjestelmiin.

Käytetty kaava

Moottoriteho (kW) = jäähdytysteho (kW) ÷ COP ÷ moottorin hyötysuhde · Iskutilavuus (m³/h) = massavirta × imupuolen ominaistilavuus

ColdMatchin kylmätekniikan insinöörien tarkastama

Näin käytät tätä laskuria
  1. 1Syötä tarvittava jäähdytysteho kW:na kuormalaskelmastasi.
  2. 2Valitse kylmäaine (NH₃, CO₂, R-448A/449A, propaani) ja höyrystymislämpötila.
  3. 3Aseta lauhtumislämpötila sijainnin ilmaston mukaan.
  4. 4Vertaa akselitehoa, COP:ia ja iskutilavuutta, ja pyydä yhteensopivia kompressoripaketteja.

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.

Usein kysytyt kysymykset

Miten kylmäkompressori mitoitetaan?

Höyrystymislämpötilan (Te), lauhtumislämpötilan (Tc), kylmäaineen ominaisuuksien ja tarvittavan jäähdytystehon perusteella — näistä saadaan moottoriteho ja iskutilavuus.

Mikä on odotettu COP?

Kylmätila: 3,5–5,0. Pakastetila: 1,4–2,2. Pikapakastus: alhaisemmat arvot.

Ruuvi- vai mäntäkompressori?

Alle 50 kW: mäntä/scroll. 50–500 kW: ruuvi. Yli 500 kW: ruuvi tai keskipakokompressori.

Mikä kylmäaine antaa parhaan hyötysuhteen?

Ammoniakki (NH₃) antaa yleensä parhaan hyötysuhteen suurissa laitoksissa, kun taas CO₂ (R-744) sopii pienen täyttömäärän järjestelmiin ja kaskadijärjestelmiin.

Miten käytän lukuja tarjouspyynnössä?

Vie jäähdytysteho, Te, Tc ja valittu kylmäaine tarjouspyyntötyökaluun, jotta toimittajat voivat tarjota yhteensopivia kompressoripaketteja. ColdMatch tarkistaa kuvauksen manuaalisesti ennen mahdollista toimittajaesittelyä.
