Answer: Under the action of the turntable and the droplet spraying device, ultra-small droplets are generated by centrifugal force, which greatly increases the evaporation surface area; The airflow blown by the powerful fan greatly improves the surface wind speed of liquid and accelerates the diffusion of gas molecules, so the evaporation of water is greatly improved, and the water absorbs heat and cools down during evaporation, which can also improve the relative humidity of air, reduce dust and purify the air. This kind of spray fan uses centrifugal force to produce droplets, so it is called centrifugal spray fan.
B: Under the action of the high-pressure water pump, the water in the high-pressure nozzle spray fan has a pressure of tens of kilograms, and water mist is generated through the high-pressure nozzle, with the droplet diameter less than 10 micron, and the evaporation surface area is greatly improved. The airflow blown by the water mist through the powerful fan greatly improves the surface wind speed of the liquid and accelerates the diffusion of gas molecules, so the evaporation capacity of water is greatly improved, and the water absorbs heat during evaporation, which reduces the temperature and improves the relative humidity of the air. This kind of fan is called high-pressure nozzle spray fan because it produces micro fog through high-pressure nozzle.

Brief introduction of evaporative spray cooling fan;
Traditional air conditioners have high energy consumption and high operating cost, which limits the purchase amount to some extent. The evaporative spray cooling fan of our company embodies the characteristics of energy saving, humanization, beauty and environmental protection, and provides a perfect solution for the ventilation and cooling of electronics, textiles, shoes, plastics, machinery workshops, cigarette factories, modern gentlemen, offices, supermarkets, hospitals, casinos, waiting rooms and other environments.
Characteristics of evaporative spray cooling fan;
1. Completely environmentally friendly products: environmentally friendly products without compressor, cold coal and pollution. It uses the principles of indoor air evaporation cooling and convection ventilation with rooms to achieve the purpose of ventilation cooling and humidity increase.
2. Low operating cost and quick investment recovery: compared with series air coolers, the power consumption is only 1/2- 1/3.
3, the cooling effect is obvious: in humid areas (such as southern areas), it can generally achieve an obvious cooling effect of about 5- 10℃; In particularly hot and dry areas (such as north and northwest), the temperature drop can reach about 10- 15℃.
4. The investment cost is low and does not occupy the building area: compared with the air cooler system, the cost is less than half, and the equipment does not occupy any building area.
5. Keep the indoor air clean, clean and hygienic: Opening doors and windows to exhaust air is a major feature of evaporative air conditioning. 100% fresh air replacement mode makes people stay in the natural environment at all times, without the discomfort caused by traditional air conditioning, and exhausts dirty air outdoors.
6. Easy maintenance and installation: the system is simple, easy to install and maintain quickly, and professional maintenance personnel are not needed.
7. Prevent dry air: It can moisturize the skin and is good for the skin.
8. Low noise and vibration
Advantages of evaporative spray cooling fan over central air conditioner and air cooler;
1. Evaporative spray cooling fan uses water to evaporate and refrigerate, with long air supply distance and large air volume, which can make the temperature distribution in closed places uniform and has filtering function. The indoor environment is comfortable, with high oxygen content and fresh air. However, the traditional central air conditioner directly uses Freon refrigeration, which leads to large air supply temperature difference, small air volume and difficult room temperature uniformity. Moreover, the ventilation function is poor, it is not suitable for semi-closed places, and it is easy to get "air conditioning disease" after long-term use.
2. The service life of evaporative spray cooling fan is twice as long as that of traditional central air conditioner, with low overall failure rate and simple and convenient equipment maintenance.
3. The spray cooling fan can increase the ambient humidity and lower the ambient temperature more effectively than the traditional air cooler;
4. Principle of spray fan: There are two options for spray cooling fan.
The spray cooling fan has the advantages of small one-time investment, high overall operating efficiency and low operating cost. Take a 2000-square-meter space as an example. Using 20 air conditioners, the operating power is 20KW at full load 1 hour, while the operating power of 40 new generation spray cooling fans is only 10KW/ hour, which can save 3000-5000 yuan per month at daily1hour.
A new generation of spray fans, spray fans, cooling fans and cooling fans make use of the advanced centrifugal secondary atomization principle to make ultra-small water droplets reach 10 micron by centrifugal force under the action of the turntable and the mist particle injection device, thus greatly improving the evaporation surface area; Droplets are blown up by the fan through airflow, which means that the surface wind speed of liquid is greatly increased and the diffusion of gas molecules is accelerated. Thereby greatly improving the evaporation of water, absorbing heat in the process of water evaporation, lowering the temperature and improving the relative humidity of air. In the use process, there is no water drop phenomenon, fine atomization and long-distance transportation. If it is used with a large-flow axial fan, it can increase the indoor exhaust air volume and airflow speed, and further improve the use effect. This technology developed rapidly in South Korea, and was introduced to China in the late 1990s, and some domestic enterprises began to apply it, but its high price discouraged most enterprises. After painstaking research, Deqing Zhongwei Electric Appliance Co., Ltd. finally completely digested and absorbed its original technology, and further improved the raw materials and processing technology on the original basis, greatly improving the use effect. Its outstanding advantages are: simple structure, can be used by single machine; Strong operability, more flexibility and wider application scope; Because the system does not need high pressure, the cost is low, and the situation that the nozzle is easily blocked is also avoided; Meanwhile, the cooling speed is faster; There is no need to modify the use environment of the workshop; Because we have been able to mass-produce, the price is very low, and the products are exported at home and abroad; At the same time, due to the adoption of new technology, the overall power of the equipment is smaller, allowing customers to save electricity and energy when they are practical. The power of a single unit is only more than 200 watts, which saves a lot of use costs for customers, and the equipment failure rate is very low. It can also save maintenance costs for customers and improve actual work efficiency.
