Cooling pad is made of corrugate fiber paper by special chemical
treatment,corrosion resistant and long service life. Water evenly
covers the surface of paper curtain. Under the negative pressure
formed by the opposite ventilator outdoor air gets through the wet
sreens, achieving the purpose of cooling . Fine infiltration and
water absorption to ensure the same temperature in the house. Our
company have several kinds of the materials of the outer frame
including aluminium alloy, galvanize board, PVC and galvanized iron
in order to meet different requirements of different customers.
Besides, customers have different need of the thickness of the
cooling pad, so we provide two styles:10cm&15cm with the
corresponding frames.
Merits of cooling pad
Water absorbing: cooling pad keeps a good ability of water absorbing and avoids the
production of bead on the surface by special formula and technical
disposal.
Instant drying: when water stops running, the protecting velum on the surface will
dry rapidly. Consequently, microorganism and algae on its surface
can be killed.
Without micro hole: algae can be prevented in its inner part and falls off from the
surface when drying.
Benefits
High evaporation efficiency
Superb wetting properties
Low pressure drop when wet,leading to lower operating costs
No water carry-over
Low scaling
Self cleaning
Strong and self supporting
Long life time
Low running costs
Quick and easy to install
Environmentally friendly
Consistant high quality
Installation design
the required air volume and the cooling pad area for a greenhouse
is calculated as follows:
suppose:the dimension of the greenhouse: 125*40=5000 sq.m
Intensity of solar radiation outside:900 walt/sq.m
Shade rate:50%(intensity of solar radiation inside is 450
walt/sq.m)
Air speed:1.5m/second
Air volume:=5000*225=1,125,000(cubic meter/hour)=312.5(cubic
meter/second)
Cooling pad area:312.5÷1.5=208.3(square meter)
That Is to say it need to install at least 208.3 sq.m cooling pad .
Installed along the side wall of the greenhouse a long 125,height
1.8m cooling pad,it’s area is 125*1.8m=225(sq.m).the cooling pad
should be Mounted on the side facing the wall of dominant wind
direction in summer,while Leeward side of the wall fan
installation.
The calculation of cooling pad for poultry house
The following calculation is used for ventilation sheds empirical
data
- for the closed sheds,7—9cubic meter/hour,,Kg live weight Province
- for the closed sheds:15cubic meter/hour, Kg live weight Province
After the cooling pad to take the following values
The thickness of the wet-curtain100mm:1.0-1.5m/sec/
The thickness of the wet-curtain150mm:1.5-2.0m/sec.
