Scenario

Standard engineering assumptions

kW refrigerasi adalah panas yang dikeluarkan dari ruang — bukan kW listrik. Daya listrik masuk ≈ beban refrigerasi ÷ COP sistem, ditambah beban peralatan bantu.

Hanya estimasi perencanaan. Kapasitas akhir, pemilihan peralatan, refrigeran, persyaratan keselamatan, harga, dan kinerja energi harus dikonfirmasi oleh penyedia sistem refrigerasi berkualifikasi yang dipilih.

Jawaban singkat

Total beban refrigerasi merupakan jumlah empat komponen: transmisi melalui selubung bangunan, penurunan suhu produk, infiltrasi udara melalui pintu, dan beban panas internal dari kipas, lampu, forklift, serta orang. Pada cold storage umumnya, transmisi menyumbang 25–40 %, produk 20–45 %, infiltrasi 15–30 %, dan beban internal 10–20 % dari total.

Rumus yang digunakan

Q total = Q transmission + Q product + Q infiltration + Q internal · Q transmission = U × A × ΔT

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.

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.

Tanya Jawab

Apa komponen beban utamanya?

Transmisi, penurunan suhu produk, infiltrasi, lampu/motor, dan personel.

Berapa U-value panel yang digunakan?

Ruang dingin 0.25–0.35, ruang beku 0.18–0.22, pembekuan cepat 0.15 W/m²K atau lebih baik.

Seberapa besar tambahan beban akibat pembukaan pintu?

Di pusat distribusi yang sibuk, infiltrasi dapat mencapai 15–25% dari total beban.

Bagaimana kalkulator menghitung total beban?

Kalkulator menjumlahkan empat komponen — transmisi selubung bangunan (U-value × surface × temperature difference), penurunan suhu produk, infiltrasi udara hangat melalui pintu, dan beban panas internal dari orang, lampu, serta kipas — lalu menerapkan margin desain. Hasilnya berupa beban perencanaan dalam kW, ditampilkan sebagai rentang, bukan satu angka.

Data apa yang dapat meningkatkan akurasi estimasi?

Data pembukaan pintu yang terukur, suhu masuk produk dan volume masuk harian aktual, U-value panel aktual dari lembar data panel, suhu lingkungan desain setempat, serta daya kipas evaporator. Setiap masukan dapat mengubah total sebesar 5–15%, sehingga alat menampilkan rentang, bukan presisi semu.

Apakah saya perlu membeli peralatan dengan kapasitas tepat sebesar beban ini?

Tidak. Beban perencanaan adalah titik awal: pemasok menambahkan margin sendiri untuk defrost, keragaman beban, beban parsial, dan kapasitas siaga. Gunakan angka tersebut sebagai dasar yang sama bagi semua pemasok agar proposal dapat dibandingkan — bukan sebagai ukuran peralatan final.

Bagaimana pembukaan pintu memengaruhi hasil?

Di pusat distribusi yang sibuk, infiltrasi saja dapat mencapai 15–25% dari total beban. Jika pintu sering dibuka atau tidak dilengkapi tirai strip, jalankan kalkulator infiltrasi pintu terlebih dahulu dan masukkan hasilnya — perbedaan antara ruang tertutup rapat dan ruang yang sibuk sering menjadi komponen selisih beban terbesar.
