Soğutma Kompresörü Boyutlandırma

Soğutma yükü ve çalışma sıcaklıklarından kompresör motor gücünü, COP değerini ve süpürme hacim debisini tahmin edin. Sonuçlar planlama tahminidir, nihai ekipman seçimi değildir.

Kısa yanıt

Kompresör boyutlandırması, kW cinsinden evaporatör yükü ve çalışma COP değeriyle başlar: mil gücü ≈ soğutma yükü ÷ COP. Tipik COP, soğuk muhafazada (−5 °C buharlaşma) 3.5–5.0, donmuş muhafazada (−35 °C) 1.4–2.2 düzeyindedir. Amonyak (NH₃), büyük tesislerde genellikle en yüksek verimi sağlar; CO₂ (R-744), düşük şarjlı ve kaskad sistemlere uygundur.

Kullanılan formül

Motor power (kW) = cooling duty (kW) ÷ COP ÷ motor efficiency · Displacement (m³/h) = mass flow × suction specific volume

Bu hesaplama aracı nasıl kullanılır?
  1. 1Yük hesabınızdan gerekli soğutma yükünü kW cinsinden girin.
  2. 2Soğutucu akışkanı (NH₃, CO₂, R-448A/449A, propan) ve buharlaşma sıcaklığını seçin.
  3. 3İkliminize uygun yoğuşma sıcaklığını belirleyin.
  4. 4Mil gücünü, COP değerini ve süpürme hacim debisini karşılaştırın; ardından ihtiyacınıza uygun kompresör paketleri için teklif isteyin.

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.

Sıkça Sorulan Sorular

Kompresör boyutu nasıl belirlenir?

Te, Tc, soğutucu akışkan özellikleri ve soğutma kapasitesinden motor gücü ve süpürme hacim debisi hesaplanır.

Beklenen COP nedir?

Soğuk muhafaza: 3.0–3.8. Donmuş muhafaza: 1.8–2.4. Şoklama: 1.3–1.7.

Vidalı mı, pistonlu mu?

<50 kW pistonlu/scroll; 50–500 kW vidalı; >500 kW vidalı veya santrifüj.

Motor gücü ve süpürme hacim debisi nasıl tahmin edilir?

Araç, soğutma yükü ile buharlaşma/yoğuşma sıcaklıklarından çevrimin soğutucu akışkana bağlı özgül işini ve yükü karşılamak için gereken kütlesel debiyi tahmin eder. Motor gücü mass flow × specific work ÷ motor efficiency ile, süpürme hacim debisi ise kütlesel debi ve emiş yoğunluğundan hesaplanır. Aynı yük için farklı soğutucu akışkanlar çok farklı süpürme hacim debileri gerektirir.

Tedarikçinin seçimi neden bu tahminden farklıdır?

Tedarikçi, kısmi yük kademeleri, yağ yönetimi ve kendi emniyet payları dahil olmak üzere tam çalışma zarfınızda gerçek bir kompresör performans haritasına göre seçim yapar. Bu araç ön değerlendirme tahmini sunar: tedarikçi seçimi doğrulamadan önce teklif edilen makinenin uygun kapasite aralığında olup olmadığını kontrol etmek için kullanın.

Kompresör seçimini kabul etmeden önce neyi kontrol etmeliyim?

Tek bir nokta yerine tüm çalışma zarfını, kısmi yük verimini, kapasite kademelerini, soğutucu akışkan bulunabilirliğini ve ülkenizdeki servis kapsamını kontrol edin. Toplam sahip olma maliyeti hesaplama aracında enerji maliyetlerini aynı temelde karşılaştırabilmek için her çalışma noktasındaki çekilen gücü isteyin.

Sıcaklık farkı arttıkça COP nasıl değişir?

Buharlaşma ve yoğuşma sıcaklıkları arasındaki fark ne kadar küçükse COP o kadar yüksektir: soğuk muhafaza odalarında genellikle 3.0–3.8, donmuş depolamada 1.8–2.4, şok dondurmada 1.3–1.7 elde edilir. Bu nedenle sıcaklık farkını gereğinden büyük tasarlamak veya yoğuşma basıncının fazla yükselmesine izin vermek, her çalışma saatinde ek maliyet oluşturur.
