Greenhouse Cooling system is mainly consisted of Exhaust fans and cooling pad.

*Greenhouse Exhaust Fan

Features:

1. The fan consists of blades, motor, frame, protect net, support frame and shutters.

The shutters open and close automatically when the fan starts up and stops running, avoiding outside dust entering the room.

2. Frame: extra thick, galvanized steel sheet, one-off molded, high strength, anti-corrosive and durable.

3. Shutter, made of high strength galvanized steel sheet, flexible operation, dustproof and waterproof.

4. Belt tensioner, made of high quality aluminum magnesium alloy, avoiding belt loosening or dropping off, extending service life of belt and avoiding distortion.

5. Strict test criterion, consist of airflow test, noise test, libration test, drive concentric test, blade RPM test, whole machine efficiency test, dynamic balance test, the thickness of the galvanized sheet test, the size of the spare parts test, etc.

Main components and parameters:

Blades are made of high quality stainless steel by CNC TURRET PUNCH PRESS, attractive and durable, special design of blade shape ensuring big air flow, no distortion ,no broken, passing the homeostasis test to ensure the air volume keeping the same as the very beginning during the operation life span.

Siemens motor or Chineses famous motor can be chose, high efficient and energy-saving with CCC certificate. Protection class, IP55, insulation class, F. The voltage ,power ,frequency and phase can be customized.


Belt impeller and pulley are made of aluminum magnesium alloy by injection molding, and pass through blast-sanding treatment for attractive appearance, reducing the weight of blade, high corrosion resistance, eliminating internal stress to improve its own rigidity and stability, high strength.

The bearing adopts special waterproof design of double-row bearing, high intension, low noise, maintenance-free and long service life.

Swung drop hammer is made of high quality nylon, stable performance, guaranteeing the shutters open and close flexibly.

*JLF Series-Evaporative Cooling Pad

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.


The cooling process of evaporative cooling system is accomplished at the paper pad. 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.

"Cooling pad +v entilation fan" tunnel ventilation is the most economical and efficient cooling way in summer. Reasonable design and installation of cooling pad with ventilation fan can control the temp at 30 degrees in the poultry house even at the hottest weather. Thus it can reduce the negative effect of high temperature on the birds to the minimum.


Specification of cooling pad

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. The hotter weather, the  bigger  temperature  gap  between dry bulb and wet bulb.

The temperature difference between the Wet-bulb and dry bulb

The frame can be made of galvanized, aluminum alloy or stainless steel, beautiful and practical, high-strength, easy to maintain and replace cooling paper. Processed antioxidant treatment, for enhance service life.

Cooling paper is made of high quality corrugated fiber paper from Kiamusze. High hygroscopicity. Good refrigeration effect.
