Greenhouse Ventilation Ventilation

Greenhouse ventilation Systems are systems that make use of distributed inlet and outlet exhaust systems to maintain steady airflow, temperature, and humidity within a greenhouse. Depending on their geographic location and ventilation needs, these systems sometimes also make use of air coolers, exhaust fans or circulation fans to help better control the trapped heat and humidity generated from growing plants.

About The Greenhouse Industry Greenhouse Industry

Commercial greenhouses are typically high-tech structures dedicated to the horticultural needs of plants, where environmental properties such as temperature, light exposure, irrigation, fertilization, humidity, and ventilation can be controlled for optimal crop growth.

Over the past decade, the world greenhouse industry has grown tremendously.  This increase is driven by the need for higher indoor production due to limited land, water, and labor.  It is crucial that commercial greenhouse managers are on the leading edge of production and operations within their facilities, understanding that their plants require constant attention and careful management to thrive.

Why We Need Greenhouse Ventilation System?

One critical element of operations for greenhouse management is climate control, which includes providing optimum lighting, heating, ventilation, insulation, and greenhouse irrigation.  Without optimal climate control, crops will generate much lower yields, decreasing the greenhouse’s profitability.  When plants receive optimal climate control, high yields are guaranteed.

Appropriate ventilation and cooling is key to achieving maximum greenhouse climate control.  The primary purpose of ventilation is to control the heat and humidity inside the greenhouse so that plants can thrive with little risk from insects and disease.  Adding exhaust fans and circulation fans can provide optimal airflow to keep commercial greenhouses from overheating.  Exhaust fans pull hot air out of the greenhouse so that fresh air enters and cools the greenhouse, greenhouse fan and pad cooling system will greatly help to cool the greenhouse in the summer.

How to Design Greenhouse Ventilation System?

There are normally 3 ways to achieve ideal climate control within the greenhouse:

  1. 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.
  2. 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. In most of cases, the evaporative cooling pads with exhaust fans combination can help to bring down the temperature by 4 to 8 degrees.
  3. 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.
