Wet curtain cooling pad for poultry farm greenhouse with Aluminum/Galvanized/SS frame

Wet Film material is the core for the humidifier. It is a plant fiber as the substrate, through the special composition of the resin processing sintering to form corrugated plate-like cross-overlapping polymer composite material, which contains slow release type of antibacterial agent, with a strong water absorption, a good self-cleaning ability, Non-toxic, resistant to mold, fire and provide the largest contact between water and air surface area.

Working Principle

Clean tap water or chilled water through a water inlet pipe to the wet film humidifier lower circulation water tank, the water enters the water tank is composed of float valve and liquid level switch to control. The water in the water tank by a water pump to wet film on top of the water distributor, through wet membrane water distributor will be uniform water distribution, water under the action of gravity along the wet membrane surface flow down the wet film, wetting, penetrating, when the air through the wet wet film during its increased humidity, temperature drop, another part without evaporation water from the humidifier bottom back to the water tank; the water in the water tank through a circulating water pump using repeated cycles, the wet film humidification of air. So as to achieve the purpose of saving water. When the circulating water level in the water tank of water drop, switch to open, to ensure water tank, the water level of the water tank is maintained at a set height range; when the circulation of the water level in the tank falls to a certain height, the water tank of the low water level switch, ensure the circulating pump in the absence of water stop. In the process of temperature and membrane water evaporated part, but does not consume additional energy.

Saturation efficiency definition

Humidification caused by changes in the state of the air near the saturation line, expressed as a percentage, it is only with the characteristics of wet film material itself, not because of wet film inlet air changes in the state.

Saturation efficiency: η=tdb-to/tdb-twb

tdb= Temperature for the Dry bulb of Wet film inlet；

twb= Temperature for the wet bulb of Wet film inlet；

to = Temperature for the Dry bulb of Wet film outlet

E.g.: Air conditioning air volume of 50000m3 / h, heating capacity of 212KW, fresh air ratio of 30%. The air temperature is 24 ℃, the relative humidity is 50%, the winter outdoor calculation parameter is -4 ℃, 75%, the wet film thickness is calculated: outdoor -4 ℃, 75% air temperature after heating 38 ℃, Relative humidity of about 5%, check the enthalpy wet chart air wet bulb temperature of 15.7 ℃.

Saturation efficiency: η=tdb-to/tdb-twb=38-24/38-15.7=62.8%

Thus we can choose the 150mm wet film to meet the humidification requirement.
