Calculateur d'énergie et de coût global de chambre froide

Saisissez les dimensions, températures, entrées journalières de produit et heures de fonctionnement. Le calculateur dimensionne la chambre, estime le bilan frigorifique et compare deux scénarios d'installation. Ajoutez votre tarif et vos coûts pour comparer construire, louer ou externaliser (3PL). Il ne fournit jamais de tarifs, de prix ni d'économies.

Méthode revue le 13 oct. 2026 · Traduction en attente de relecture native.

1 · Chambre et produit

Surface

200 m²

Volume intérieur brut

1 200 m³

Puissance frigorifique de calcul (avec marge)

24,7 kW · 7 TR

Fourchette de planification: 17,9–31,5 kW

Répartition du bilan: Transmission 39% · Produit 6% · Infiltration par les portes 46% · Apports internes 8%

2 · Scénarios énergétiques A et B

kW frigorifiques par kW électrique, d'après les données de chaque fournisseur à vos conditions de calcul.

Saisissez un COP supérieur à zéro pour les deux scénarios.

3 · Coût global : construire ou louer / 3PL (facultatif)

Utilisez des montants chiffrés. Laissez vide pour ignorer.

Saisissez l'investissement et le coût de location pour comparer.

Estimation de planification. La conception finale, le choix du fluide et la conformité réglementaire doivent être validés par un ingénieur frigoriste qualifié.

ColdMatch est un service d'achat accompagné : vous soumettez votre projet, notre équipe l'analyse et le structure, puis contacte pour vous des fournisseurs adaptés. Pas de mise en relation directe avec les fabricants. Gratuit pour les acheteurs ; projets à partir de 250 000 USD.

Hypothèses et sources

  • Propriétés du produit : chaleur massique 3,5–3,6 kJ/kg·K au-dessus de la congélation, 1,8–1,9 en dessous, chaleur latente 240 kJ/kg en surgelé, point de congélation −2 °C (valeurs typiques, ASHRAE Handbook — Refrigeration, ch. 19, 2022).
  • Porte : 4,5 m², 30 s par ouverture ; masse volumique de l'air 1,2 kg/m³.
  • Apports internes, ventilateurs et dégivrage selon les forfaits documentés du modèle ColdMatch.
  • Marge de sécurité et fourchette d'incertitude selon la page méthodologie de ColdMatch.
  • COP, tarif, investissement, maintenance et location sont fournis par vous.

Formules

  • Volume = longueur × largeur × hauteur
  • Puissance de calcul = (transmission + produit + infiltration + internes) ÷ heures de marche × 24 × (1 + marge)
  • kWh annuels = kWh thermiques journaliers × 365 ÷ COP
  • Coût actualisé = investissement + Σ coût annuel ÷ (1 + r)^t, t = 1…n

Questions

Comment le bilan frigorifique est-il calculé ?

Il additionne quatre postes : chaleur traversant parois, toiture et sol ; chaleur du produit entrant ; air chaud entrant par les portes ; et apports de l'éclairage, du personnel, des chariots, ventilateurs et dégivrage. Le total journalier est réparti sur les heures de marche du compresseur, avec une marge.

Pourquoi saisir moi-même le COP et le tarif ?

Le rendement et le prix de l'électricité dépendent de la conception, du fluide, du climat et du contrat. Les données fournisseur et votre tarif évitent des économies inventées.

Puis-je utiliser les unités métriques et US ?

Oui. Changez d'unités à tout moment ; les valeurs sont converties, pas effacées.

Est-ce suffisant pour acheter ?

Non. C'est un outil de planification. Un ingénieur qualifié doit valider la conception et les fournisseurs doivent chiffrer sur un cahier des charges complet.
