cooling water curtain wall

What are the advantages and scope of application of water curtain fans?

Water curtain fans have low investment, high efficiency, low power consumption, good air quality, strong cooling effect, stable performance, and reliable quality; “It is widely used in the fields of civil use, agriculture, industrial equipment, and other fields. Below is a detailed introduction to the advantages and application range of water curtain fans.”.

1、 Advantages of water curtain fan

1. Low investment and high efficiency

When installing central air conditioners under the same conditions and areas, compared to environmentally friendly air conditioners, environmentally friendly air conditioners account for 1/5 of the total investment in central air conditioners.

2. Low power consumption, only 1 kWh per hour

Installing central and environmentally friendly air conditioners in the same area requires only 1/10 of the power consumption of central air conditioners.

3. Good air quality

Environmentally friendly air conditioners integrate ventilation, ventilation, dust removal, and cooling to increase the oxygen content of the space and improve work efficiency. Natural or refrigeration air supply is optional.

4. Strong cooling effect

In southern regions, machines can generally achieve a cooling effect of 4 ℃ – 10 ℃, while in hot and dry regions, machines can achieve a cooling effect of 4 ℃ – 15 ℃, and the cooling is rapid.

5. Large air volume and remote air supply

The maximum air volume per hour per 100 square meters is 18000 to 60000 cubic meters.

6. Stable performance and reliable quality

Adopt 100mm thick “5090 evaporation filter screen” with strong cooling capacity, and adopt three blade forward swept axial flow fan blades, which have low noise and high efficiency.

7. Adjust humidity

Conduct humidity adjustment for workplaces that require increased air humidity.

8. Efficiency and convenience

Leading intelligent control can arbitrarily group multiple devices. Remote Internet PCs and mobile phones control the startup, shutdown, refrigeration, cleaning, and other functions of the unit, greatly improving the efficiency and convenience of equipment operation management

Advantages of aquaculture water curtain

1) The evaporative cooling pad is a spatial cross connection technology made of corrugated paper, which has high absorption, water resistance, mold resistance, and long service life.

2) Large evaporation area, with a cooling efficiency of up to 80%.

3) Evaporative cooling pad paper absorbs water naturally, spreads quickly, and has a long-lasting effect. A drop of water can disperse in 4-5 seconds. The natural absorption height is 60-70 mm/5 minutes, 200 mm/1.5 hours, meeting departmental standards.

4) Cooling pad products do not contain chemicals such as phenol that can cause skin irritation. It is energy-saving, environmentally friendly, and economically durable.

5) It does not contain chemicals such as phenol and will not cause skin allergies. Harmless, green, energy-saving, environmentally friendly, economical, and applicable.

6) There are galvanized sheet and aluminum composite sheet frames for selection.

Due to a lack of understanding among many people about the cooling water curtains used in aquaculture farms, it is easy to mistakenly use them.

Mistake 1 of using cooling water curtains in aquaculture farms: The lower the water temperature, the more obvious the cooling effect.

As the water temperature rises, evaporation also occurs_ Intensification, evaporation intensification, heat carried away by water_ Increase. That is, the cooling effect is also_ The more obvious.

Therefore, room temperature water can achieve very good results and can also be recycled to reduce water resource waste.

Mistake 2 of using cooling water curtains in aquaculture farms; The wetter the wet curtain, the more obvious the cooling effect

Under the action of the water pump and gravity, water flows from top to bottom, forming a wrinkled water film with a total area equivalent to more than 10 times the outer surface area of the water curtain on the corrugated fiber surface of the wet curtain_ The contact area between air and water film, thereby_ Good cooling effect.

If the water curtain is too wet and even forms flowing water_ There may be situations where long flowing water blocks the pores of the water curtain, reducing the contact area between the water curtain and air, thereby reducing the cooling effect.

Mistake 3 of using cooling water curtains in aquaculture farms: When using both wet curtains and ventilation windows, the more uniform and stable the temperature is

Due to the “pressure difference” caused by the suction of negative pressure fans, outdoor air will quickly detour through the cooling water curtain and collide with the water film, facilitating the rapid absorption of heat in the air by a wide area of water film. Once the “pressure difference” fails to meet the requirements, the effect of water film colliding with air_ It will decrease, thereby affecting the cooling effect.

Therefore, the simultaneous use of ventilation windows and wet curtains will reduce the speed of air passing through the wet curtains, thereby affecting the cooling effect.

Mistaken use of cooling water curtains in aquaculture farms: Do not clean the wet curtains before use and use them directly

Due to debris blocking the small holes of the water curtain, the water flow is unevenly distributed within the water curtain, and the wind cannot penetrate the water curtain, resulting in a decrease in cooling and ventilation effects, which cannot achieve the purpose of cooling.

Precautions for installing cooling water curtains: Introduction to the advantages of using water curtains in aquaculture farms

1. The water curtain is blocked, and if used for a long time, it is never cleaned. The water curtain will be filled with bacteria, dirt, and other factors that affect cooling. Therefore, we need to clean it regularly to avoid the breeding of bacteria.

2. Insufficient water curtain area.

3. Insufficient number of fans.

4. The standardized chicken coops are not tightly closed.

5. The density of the chicken coop is too high.

6. The fan belt is too loose.

Applicable conditions for installing cooling water curtains:

1. The chicken coop should be a closed type, with all ventilation outlets of the iliac water curtain inlet and exhaust fan outlet closed as much as possible.

2. According to the large quantity and weight of chickens raised, the required curtain area for cooling the feet during the hot summer season is required.

3. The exhaust air volume of the exhaust fan is sufficient. What are the benefits of using water curtains to cool down in summer

In addition to the above points, the water storage tank should be well lit and shaded, and the lower the water temperature, the better the effect. Don’t always expect the temperature inside the house to drop to an ideal level, as the higher the air humidity, the worse the cooling effect of the water curtain. The longer the water curtain is opened, the greater the humidity in the shed, and the less significant the effect. It may also bring management troubles such as wet bedding, increased dirt, increased E. coli infection and coccidiosis. Therefore, it is advisable to use exhaust fans as much as possible to prevent heatstroke, and use water curtains when the temperature is too high, which has a good overall effect.
