Greenhouse cooling system - Shanghai J.L Horticulture and Agriculture Supplies

Evaporative Cooling Pad
  • Features and Quality


  1.  Made of corrugated fiber paper with the spatial crossing linking technology, high absorbability, high water resistant, corrosion resistant and anti-mildew.
  2.  High hygroscopicity, to absorb water naturally, with fast speed of pervasion and lasting effectiveness.
  3.  Specific stereoscopic structure, supplying enough surface area for heat exchange of the water and air
  4.  No micro hole on the surface. No phenol in the raw material.


  • Function


The cooling process of Evaporative greenhouse Cooling System is accomplished at the paper pad. This cooling pad is made of corrugated fiber paper which is covered by thin layer water film. When the outside hot air passes through the paper, water on the thin film will absorb the heat in the air and evaporate into vapor. And the cool and humid air will enter the room. The processing is just like the wind blowing through the water level.

  • The temperature difference between the Wet-bulb and dry bulb:


Temperature of the dry bulb and the wet bulb is different at any time in the outside. Temperature of the dry bulb is high, and that of the wet bulb is lower. In hotter weather, the bigger temperature gap between dry bulb and wet bulb.


  • Frame of Cooling Pad:


The frame can be made of galvanized aluminum alloy or stainless steel, beautiful and practical, high-strength, easy to maintain and replace cooling paper.
Antioxidant treatment process enhanced service life.
Cooling paper is made of high quality corrugated fiber paper from Kiamusze. High hygroscopicity, good effect of refrigeration.

Wet curtain cooling system
Wet curtain cooling system with Cooling Pad and ventilation fans is a new type of energy saving cooling equipment. It has the advantages of the simple structure, large production capacity, low price, low power consumption, fresh air, good cooling effect. This cooling system can be widely used in the high temperature workshop and greenhouse. The principle of cooling in nature: water evaporation on the wet curtain will reduce the temperature, water on the surface of the corrugated paper fiber has a thin layer film, when the dry hot air outdoor by drawing of ventilation fans goes through the paper pad, water film on the pad will absorb the heat in the air and vaporized into steam, so that the cooling and humid air come into the room. The wet curtain cooling principle is the effective combination of wet curtain and ventilation fans to achieve cooling purposes.
