Ventilation exhaust fans and Circulation Fans: Installing box type or cone type exhaust fans in the wall of the greenhouse, and hang the circulation fans under the roof of the greenhouse, this way is similar to the first natural ventilation, but the air exchange speed is much higher due to the ventilation of the exhaust fans and circulation fans.In most of cases, the evaporative cooling pads with exhaust fans combination can help to bring down the temperature by 4 to 8 degrees.
Greenhouse with Fan & Pad cooling System Technical. Fan and Evaporative Cooling Pad System: installing evaporation cooling walls in one side of the greenhouse, and install the negative pressure exhaust fans on. Fan and Evaporative Cooling Pad System: installing evaporation cooling walls in one side of the greenhouse, and install the negative pressure exhaust fans on the opposite side of the greenhouse, it is the most cost-effective way to bring down the temperature inside the greenhouse in hot summer. All material used in structure like connectors, bracket & fasteners are of hot dipped galvanized.Natural ventilation: there are scrolling up sidewalls or open roof in the greenhouse for ventilation, the fresh cold air comes through the sidewall opennings of the greenhouse, then the heated air rises up in the greenhouse and vent out though the roof openning.Fresh air exchange can help to bring down the temperature inside the greenhouse.It is used to cool the air by using the heat present in the air. There are normally 3 ways to achieve ideal climate control within the greenhouse: We fabricate qualitative range of Fan, Pad Evaporative Cooling System.
