Scenario

Standard engineering assumptions

I kW frigoriferi indicano il calore asportato dalla cella, non i kW elettrici. Potenza elettrica assorbita ≈ carico frigorifero ÷ COP del sistema, più i carichi ausiliari.

Stima esclusivamente preliminare. La potenza definitiva, la selezione delle apparecchiature, il refrigerante, i requisiti di sicurezza, il prezzo e le prestazioni energetiche devono essere confermati dal fornitore qualificato di impianti frigoriferi selezionato.

Risposta rapida

Il carico frigorifero totale è la somma di quattro componenti: trasmissione attraverso l'involucro, raffreddamento del prodotto, infiltrazioni d'aria dalle porte e apporti interni di ventilatori, luci, carrelli elevatori e persone. In un deposito frigorifero tipico, la trasmissione rappresenta il 25–40 %, il prodotto il 20–45 %, le infiltrazioni il 15–30 % e gli apporti interni il 10–20 % del totale.

Formula utilizzata

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

Verificato dagli ingegneri frigoristi ColdMatch

Come utilizzare questo calcolatore
  1. 1Inserisci dimensioni della cella, spessore dei pannelli e temperatura ambiente di progetto.
  2. 2Aggiungi la quantità giornaliera di prodotto in ingresso e la relativa temperatura.
  3. 3Imposta le aperture giornaliere delle porte e il carico delle apparecchiature interne.
  4. 4Verifica la ripartizione per componente e usa i kW totali per la selezione delle apparecchiature.

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.

FAQ

Quali sono le principali componenti del carico?

Trasmissione, raffreddamento del prodotto, infiltrazioni, illuminazione/motori e personale.

Quale trasmittanza usare per i pannelli?

Celle a temperatura positiva 0.25–0.35, celle per surgelati 0.18–0.22, celle di abbattimento 0.15 W/m²K o migliore.

Quanto incide l'apertura delle porte?

Nei centri di distribuzione ad alta movimentazione le infiltrazioni possono raggiungere il 15–25% del carico totale.

Come calcola il carico totale il calcolatore?

Somma quattro componenti — trasmissione attraverso l'involucro (U-value × surface × temperature difference), raffreddamento del prodotto, infiltrazioni di aria calda dalle porte e apporti interni di persone, illuminazione e ventilatori — quindi applica un margine di progetto. Il risultato è una potenza preliminare in kW, espressa come intervallo anziché come valore singolo.

Quali dati renderebbero la stima più precisa?

Aperture delle porte misurate, temperature reali di ingresso del prodotto e quantità giornaliere, trasmittanza effettiva dei pannelli ricavata dalla scheda tecnica, temperatura ambiente locale di progetto e potenza dei ventilatori degli evaporatori. Ogni dato può modificare il totale del 5–15%: per questo lo strumento indica un intervallo anziché una precisione apparente.

Devo acquistare apparecchiature dimensionate esattamente su questo carico?

No. Il carico preliminare è il punto di partenza: i fornitori aggiungono i propri margini per sbrinamento, contemporaneità dei carichi, funzionamento a carico parziale e capacità di riserva. Usa il valore per fornire a tutti la stessa base e ottenere proposte confrontabili, non come dimensionamento definitivo delle apparecchiature.

Come influiscono le aperture delle porte sul risultato?

Nei centri di distribuzione ad alta movimentazione le sole infiltrazioni possono raggiungere il 15–25% del carico totale. Se le porte si aprono spesso o non hanno tende a strisce, usa prima il calcolatore delle infiltrazioni dalle porte e inserisci il valore ottenuto: la differenza tra una cella chiusa e una ad alta movimentazione è spesso la singola voce più rilevante del carico.
