Systems for the cooling of greenhouses and farms that through the evaporation of the water that flows in specific membrane panels called "pads", which filter the hot outside air managing to lower the temperature by 5-10 ° C.
These cooling systems are integrated into industrial buildings, farms and greenhouses in combination with air extractors, intakes and air circulators.
The image below shows the position in an evaporative cooling system for an example greenhouse:
PAD filtration panels can be requested in different heights and materials.
The most efficient pad in terms of cooling is certainly the CELdek pad, in cellulose paper specially designed and chemically treated to resist deterioration while meeting Greenguard environmental certification standards, improving air quality for both humans and children. animals.
The unequal pad design with cross grooves promotes beneficial mixing of air and water for optimal cooling. This unique design also has the function of continuously directing more water to the air entering the pad surface, where hotter, drier, dirtier and more intense evaporation occurs.
RCP plastic pads, on the other hand, are made of plastic and are more resistant to wear than CELdeks, however, to the detriment of cooling efficiency. In short, the advantages and disadvantages of the two different pads can be summarized with the following table:
|Parameter||CELdek PAD||RCP Plastic PAD|
|Compatible Tanks||WDP, MPG||MPG|
WDP is a complete water supply and drainage system for humidifying the walls of PADS cooling panels.
This system includes:
The WDP system is specially designed to ensure uniform humidification of CELdek cellulose paper evaporative cooling panels.
It is a modular system, without glue, which guarantees greater reliability than the WDP system. The risks of water leaks in the seams due to improper gluing and thermal expansion and contraction of materials causing tearing of the glue are frequent and this glue-free MPG system compensates for thermal expansion and contractions of the materials, allowing the water reservoir to expand freely within the joints, without the risk of water leaking.
The advantages of the MPG system:
