Evaporative Cooling Greenhouse Ventilation Diagram

Two evaporative cooling systems are commonly used in greenhouses.

Evaporative cooling greenhouse ventilation diagram.

In addition to passive cooling techniques one of the most common and efficient ways to cool a greenhouse is through evaporative cooling. A large number of hanging baskets tends to reduce natural cooling. Additional cooling when the regular ventilation system is unable to provide sufficient cooling for greenhouse temperature control additional cooling is needed. It was reported that greenhouse temperature could be reduced by 3 6c as compared to the ambient temperature and with assisted fan ventilation such.

Note that swamp coolers can be considered stand alone evaporative cooling systems but otherwise operate similarly as pad and fan systems. Fan cfm needed this is the optimal exhaust fan cfm cubic feet per minute rating for your greenhouse. A fan this size will exchange the air in your greenhouse at least once per minute which is recommended for venting small greenhouses. Pad and fan systems are part of a greenhouse s mechanical ventilation system.

Peak height of greenhouse. Similar to humans sweating a plant transpires moisture through its stomata. Evaporative cooling either a fog system or portable evaporative coolers can give added cooling. Two cooling systems the pad and fan and a fog system are commonly used in greenhouses.

Offers great range of products to cool your greenhouse effectively and efficiently. W x l x h x 0 85. Designed with the grower in mind these cooling pads and systems will use heat in the air to evaporate water from plants and other wetted surfaces that will then cool your structure. Evaporative cooling achieve and maintain cooler temperatures in your greenhouse in any climate with a cost effective evaporative cooling system.

Both make use of the cooling effect resulting from the evaporation of water. As this cooled air moves along the width of the greenhouse it sucks up heat so that the exhaust air is warmer than the inlet air. Typical fan and pad greenhouse arrangement. In fact plants use their own evaporative cooling process which we refer to as transpiration.

The coolest area of the greenhouse is adjacent to the evaporative cooling pads. Call us at 800 346 9902. April 12 2017 air circulation greenhouse cooling greenhouse ventilation proper ventilation workplace safety a number of factors weigh in the balance for successful cooling in the greenhouse including sensitive plant species humidity levels and workplace safety for employees and visitors alike.
