Cooling Fan Prevent Dirt, Dust

Evaporative Cooling Fan is the use of water evaporation to absorb the heat around the principle of cooling the air, the core components for the evaporation of wet curtain, water and air at the same time through the wet curtain, the process of mutual contact evaporation, heat absorption, cooling. Air in the evaporation of the same time, the humidity will be a certain increase.

Evaporative Cooling Fan for cooling, the size of the cooling rate is mainly related to the relative humidity of the local air. The smaller the relative humidity, the greater the temperature drop. In the low humidity areas such as Xinjiang, the temperature range of up to 20 ℃. And such as Guangdong, such as high humidity areas, the cooling rate may be only 2 ℃. So in the choice of buying a Cooling Fan, the first thing to consider is the area you use to see if your local climate can meet your cooling needs.

As the evaporative Cooling Fan in the cooling at the same time will increase the humidity of the air, in order not to increase the humidity of the air is very large, generally evaporative Cooling Fan used in outdoor open environment or open the doors and windows of the room. At this time in the choice of Cooling Fan specifications, mainly in the cold air can reach the range to be set. It depends mainly on the individual's feeling that there is no uniform standard. But generally every 200m3 / h of the air volume, probably can cover the range of 1 m3.

For the installation of a Cooling Fan in the window or through the wall outlet into the cold air of the larger air-conditioning, when it has a good air outlet, it can be used as air conditioning. At this time in the choice of Cooling Fan specifications, you first in accordance with the way the air conditioning to calculate the cooling load of the room, and then calculate the Cooling Fan in the local climate conditions, the cooling capacity to see the cooling capacity of the Cooling Fan can meet the room cooling load Claim. This calculation is scientific and accurate, but it requires professional and technical personnel to carry out, generally non-professionals are difficult to grasp. For non-professionals, the estimation method is mainly used. The general selection principle is: residential building 150m3 / m2 * h, office building 250m3 / m2 * h, public buildings 170m3 / m2 * h, ordinary industrial plant 300m3 / m2 * h. However, when using the estimation method to note that the above principle is only for ordinary buildings. When the building in the high height, poor maintenance structure, West sun serious, the room at the top, more indoor staff, heat and the larger local climate and humidity, etc., the amount of air required per unit area will increase.

For the traditional air-conditioned air-conditioned rooms, it is generally in the cooling at the same time leaving the indoor air humidity. People in this environment for a long time, will feel the air dry, uncomfortable. Since evaporative chillers increase the humidity of the air while cooling, a good way to use evaporative chillers is to use evaporative chillers in conventional air-conditioned rooms. At this point, not only can make the indoor air humidity to maintain a comfortable range, but also can greatly save the traditional air-conditioning consumption of energy, can be described as two birds with one stone. In this case, the specifications of the Cooling Fan are generally selected according to the standard of 75m3 / m2 * h.

Evaporative cooling fan In actual use, if the room window can be opened, you need to open the window. But if all the windows open, will make the indoor temperature drop down, generally open area accounted for the wall area of 4 to 5% is appropriate. At the same time the windows should be opened to avoid all open on the same wall or the distance between the windows is too small, resulting in air "short circuit", the formation of air space "dead zone."

Evaporative Cooling Fan in the course of the wet curtain should pay attention to the wet, once found wet curtain can not be completely wet, should contact the relevant departments or personnel for maintenance. For fans and pumps can be separated from the start of the model, boot should first open the pump, 3 to 5 minutes after the fan; shut down the first pump, the wind speed to high, the use of fans to dry the wet curtain, 5 minutes later And then turn off the fan, cut off the power.

In order to avoid impurities in the water on the wet curtain to form fouling, clogging, should pay attention to water quality control, to prevent the circulating water impurity content is too high, try to use a more pure water, and run the remaining water after the day off, the next day before running back Add water; conditions permit the water can be filtered or the appropriate increase in the number of cleaning; use a period of time if the air smell should be immediately contact the relevant professionals to check, if necessary, change the evaporation of the core or filter.

Long-term use, the tank, sink, air filter, wet curtain evaporator, anti-static filter, etc. can be cleaned once every two weeks to prevent dirt, dust, minerals and other clogs; long time not used or seasonal When used, should also be the tank, sink, air filter, wet curtain evaporator, anti-static filter for cleaning, with water (or add a small amount of detergent) wipe the machine shell, and then turn off the pump power, open the fan, Curtains to dry, to prevent the breeding of mold, and then put it into the box put away; refrigeration season began to use, should check the wet curtain, air filter and so on whether the mold, insects or clogs, whether there is odor, waterway (water pump, (Fan, outlet, etc.) whether the dust, power wiring is intact, the need to replace the parts to be replaced, the need for cleaning for cleaning.

Under normal circumstances, wet curtain core life of up to 5 to 10 years. For areas where the water quality is relatively large, wet curtains are prone to fouling, and care should be taken to replace the wet curtains. Generally speaking, the visible wet curtain fouling to 1/3 of the area, that should be replaced, to ensure the operating results.
