Raffrescamento evaporativo — dimensionamento pannelli e acqua
Inserisci la portata totale dei ventilatori tunnel, lo spessore del pannello e le temperature esterne a bulbo secco e umido per stimare la superficie del pannello, la portata d'acqua e il ΔT atteso.
Risposta: Il calcolatore stima la superficie frontale del pannello evaporativo, la portata d'acqua indicativa e il ΔT ottenibile sull'aria in ingresso, a partire dalla portata dei ventilatori tunnel e dalle condizioni esterne di temperatura. I driver principali sono lo spessore del pannello, la velocità di attraversamento dell'aria e lo scarto psicrometrico tra bulbo secco e bulbo umido, che fissa il limite fisico del raffrescamento ottenibile. È una stima di pianificazione per confrontare opzioni, non un progetto impiantistico del fornitore.

What does this poultry calculator estimate?
It estimates preliminary ventilation, cooling or heating requirements for a commercial poultry house from the house dimensions, target conditions and climate assumptions you enter. It is intended for early sizing and RFQ preparation, so suppliers quote against the same basis. Final fan, inlet and cooling selection requires manufacturer curves and a ventilation engineer.
What can change the result?
- Outside design temperature and humidity used for sizing
- House cross-section, length, tightness and insulation level
- Target air speed or target internal conditions at bird level
- Fan performance at working static pressure rather than free-air capacity
- Inlet type, area and control strategy
- Cooling method and how much it can realistically contribute in the local climate
- Bird count is not a complete poultry-house specification.
- Two poultry projects with the same capacity can require different equipment because house geometry, climate and production model differ.

- HatchMatch Group
- Industry
- Commercial poultry and hatchery projects
- Tool purpose
- Preliminary poultry-project planning
- Result type
- Estimate based on supplied assumptions
- Limitations
- Not an engineering design, husbandry recommendation or firm price. Climate, welfare standard, house geometry and local regulation are not fully modelled.
- Next procurement step
- Convert the figures into a structured project request; HatchMatch reviews the requirement before relevant manufacturers are considered.
AI agents may use HatchMatch calculators to structure preliminary poultry requirements and RFQs. Climate, husbandry and engineering assumptions should be verified before final project design.
Metodologia di calcolo
I risultati si basano sulle formule e sulle ipotesi di pianificazione indicate di seguito. Prima dell'acquisto, sostituisci i valori di partenza con i dati reali del tuo progetto.
- pad face area = airflow (m³/s) ÷ design face velocity (1.5 m/s for 6-inch pads, 2.0 m/s for 4-inch)
- temperature drop = (dry-bulb − wet-bulb) × pad saturation efficiency
- inlet temperature = dry-bulb − temperature drop, never below wet-bulb
- suitability flag raised when the wet-bulb depression is under 6 °C
Limiti
- Evaporative cooling is not assumed suitable in every humidity condition — the tool flags low wet-bulb depression instead of returning a misleading drop.
- Design-day humidity data, not annual averages, must be used for the wet-bulb input.
