Evaporative Cooling Greenhouse Ventilation Diagram

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 greenhouse ventilation diagram.

The coolest area of the greenhouse is adjacent to the evaporative cooling pads. Two cooling systems the pad and fan and a fog system are commonly used in greenhouses. 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.

Fan cfm needed this is the optimal exhaust fan cfm cubic feet per minute rating for your greenhouse. 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. Offers great range of products to cool your greenhouse effectively and efficiently.

For greenhouse ventilation and cooling systems atlas manufacturing inc. In fact plants use their own evaporative cooling process which we refer to as transpiration. Both make use of the cooling effect resulting from the evaporation of water. In addition to passive cooling techniques one of the most common and efficient ways to cool a greenhouse is through evaporative cooling.

Continued developments in the design of natural ventilation systems are giving growers better control of temperature and humidity at lower cost. 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. They considered an external evaporative cooling of greenhouse air by providing surrounding shallow water ponds and floating wetted surfaces and developed thermal model to predict its performance.

It was reported that greenhouse temperature could be reduced by 3 6c as compared to the ambient temperature and with assisted fan ventilation such. Call us at 800 346 9902. W x l x h x 0 85. Evaporative cooling achieve and maintain cooler temperatures in your greenhouse in any climate with a cost effective evaporative cooling system.

Peak height of greenhouse. Typical fan and pad greenhouse arrangement. 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.
