It requires less energy n comparison with pad and fan cooling. Pressure differences created by the wind and temperature in the inside and outside of a greenhouse. Natural ventilation is the result of The pad and fan cooling system work by using exhaust fans that suck warm air out of the greenhouse creating air flow over evaporative cooling pads.
Natural, Passive Ventilation with High Pressure Fogging Natural ventilation Water consumption is higher in pad and fan cooling compared with high pressure fogging. This is a popular method for cooling greenhouses and can reduce temperatures significantly (between 5-10 ☌ depending on the relative humidity) but it has various disadvantages: 1. The pad and fan cooling system work by using exhaust fans that suck warm air out of the greenhouse creating air flow over evaporative cooling pads.
Forced Evaporative Cooling Ventilation Pad and with Fan Pad and fan These solutions are either passive (natural) or forced (mechanical). It therefore goes without saying that an effective greenhouse cooling system is one of the most important considerations for greenhouse growers. gr eenh ous es I sha de net I hy dr oponics I aquap onics Commercial greenhouse cooling systems: Natural ventilation compared with forced evaporative pad and fan High greenhouse temperatures are extremely detrimental to optimum plant health and growth, which obviously has a negative effect on commercial greenhouse farming yields and profitability.
