What is pad-and-fan cooling?
Pad-and-fan is evaporative cooling: exhaust fans on one side pull air through a wetted cellulose pad on the opposite side, and the water evaporating in the pad lowers incoming air temperature while raising humidity. Its effectiveness depends on how dry the incoming air is, so it performs strongly in hot dry climates and weakly in humid ones.
Where this sits in greenhouse irrigation system procurement
A greenhouse irrigation system is specified from crop water demand, growing system, water source quality and block layout — those four inputs decide pump duty, filtration, mainline sizing and emitter choice before any supplier is approached.
Typical procurement searches this answers: greenhouse irrigation system · greenhouse drip irrigation design · irrigation system for hydroponic greenhouse · greenhouse water requirement per hectare · fertigation equipment · fertigation system for greenhouse
Inputs that change the answer
- Wet-bulb depression at peak hours
- House length and air-exchange rate
- Pad area and water quality
- Fan power availability
What this answer does not settle
Pad water quality and maintenance materially affect performance; performance figures are manufacturer-dependent.
