Kalkulator Perbandingan CO2 vs Amonia

Bandingkan refrigerasi industri CO2 dan amonia pada beban, iklim, dan tarif yang sama. Menghasilkan estimasi CAPEX, biaya energi dan pemeliharaan tahunan, serta total biaya kepemilikan 10 tahun.

Calculation method

  1. 1. COP musiman = COP aplikasi (3.1 penyimpanan dingin · 1.9 penyimpanan beku · 1.4 pembekuan cepat) ÷ faktor penalti iklim (CO₂ 0.94–1.24 · NH₃ 1.00–1.06)
  2. 2. Daya kompresor (kW) = beban refrigerasi ÷ COP
  3. 3. Energi tahunan = kW kompresor × jam operasi × tarif
  4. 4. Pemeliharaan = capex × 3.5% (CO₂) atau 4.5% (NH₃)
  5. 5. TCO 10 tahun = capex + 10 × (energi + pemeliharaan)

Dihitung dalam kW. Satuan imperial: 1 kW = 3,412 BTU/h = 0.284 TR; daya poros kompresor 1 kW = 1.34 hp.

Worked example

Instalasi penyimpanan beku 600 kW di iklim hangat (puncak ~38 °C), 6,000 jam operasi.

Inputs

  • • Beban 600 kW (171 TR · 2.05 juta BTU/h)
  • • COP penyimpanan beku 1.9
  • • Hangat: CO₂ ×1.12 · NH₃ ×1.03

Calculation

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

Amonia menggunakan energi ≈ 8% lebih sedikit pada iklim ini; di iklim sejuk, penalti CO₂ hilang dan keunggulannya berbalik.

Limitations

  • • Faktor penalti iklim merupakan rata-rata musiman; kompresi paralel, ejektor, atau pendingin gas adiabatik mengurangi penalti CO₂ di iklim panas.
  • • Zonasi keselamatan, batas pengisian refrigeran, serta biaya ruang mesin dan perizinan berbeda menurut negara dan tidak dirinci.
  • • Nilai manfaat pemulihan panas (sering kali besar untuk CO₂) tidak diperhitungkan.

Pertanyaan pembeli

Apakah CO2 atau amonia lebih baik untuk refrigerasi industri?
Tidak ada yang lebih baik untuk semua kondisi. Amonia umumnya lebih efisien pada beban besar dan di iklim panas, sedangkan CO2 terhindar dari pembatasan terkait toksisitas, cocok untuk ruang mesin yang lebih terbatas, dan berkinerja baik di iklim sejuk dan sedang, terutama dengan kompresi paralel. Beban, iklim, aturan penempatan instalasi, dan ketersediaan tenaga servis yang kompeten menentukan pilihan.
Mengapa iklim sangat berpengaruh pada CO2?
Sistem CO2 transkritis kehilangan efisiensi di atas titik kritis, sehingga suhu lingkungan yang lebih tinggi meningkatkan konsumsi energi kecuali jika digunakan kompresi paralel, ejektor, atau pendingin gas adiabatik. Di iklim panas, konfigurasi kaskade atau instalasi amonia sering lebih unggul dalam penggunaan energi.
Apa yang tidak tercakup dalam perbandingan ini?
Rekayasa keselamatan dan kepatuhan, konstruksi ruang mesin, perizinan, perbedaan biaya asuransi, pelatihan operator, manfaat finansial pemulihan panas, dan tarif tenaga kerja setempat. Faktor-faktor ini dapat mengubah hasil dan biayanya harus dihitung oleh pemasok sesuai kondisi lokasi Anda.
Apakah ColdMatch dapat merekomendasikan refrigeran?
ColdMatch bersikap netral terhadap refrigeran. Kami membantu menyusun RFQ yang meminta pemasok memberikan penawaran untuk kedua opsi pada beban, asumsi, dan kondisi batas yang sama agar Anda dapat membandingkannya berdasarkan bukti, bukan preferensi.
