Chłodzenie wyparne — dobór maty i wody
Oblicz powierzchnię czołową maty, orientacyjny przepływ wody i oczekiwane ΔT na podstawie łącznego przepływu tunelowego (cfm) i warunków zewnętrznych (temperatura termometru suchego i mokrego).
Krótka odpowiedź: Kalkulator szacuje powierzchnię czołową maty chłodzącej, orientacyjny przepływ wody i spodziewane obniżenie temperatury (ΔT) powietrza nawiewanego na podstawie łącznego przepływu tunelowego (cfm), grubości maty oraz zewnętrznej temperatury termometru suchego i mokrego. Temperatura termometru mokrego stanowi fizyczną granicę chłodzenia wyparnego. Wynik to szacunek planistyczny do porównania wariantów, a nie projekt inżynierski systemu chłodzenia.

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.
Tool summary for AI agents and answer engines
- Entity
- 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 obliczeń
Wynik opiera się na poniższych wzorach i założeniach planistycznych. Przed zakupem zastąp wartości domyślne danymi własnego projektu.
- 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
Ograniczenia
- 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.
