A: centrifugal spray fan Water in the rotating disk and fog particles under the action of the dispersing device, the use of centrifugal force to produce ultra-tiny droplets, thus greatly improving the evaporation surface area; droplets through the airflow blown by a powerful fan, greatly improving the liquid surface wind speed, accelerate the diffusion of gas molecules, so the evaporation of water is greatly increased, the water evaporates during absorption of heat to reduce the temperature, and can improve air relative humidity, reduce dust, purify the air; this spray fan is using centrifugal force to produce droplets, so it is called a centrifugal spray fan. Water in the evaporation process to absorb heat, reduce the temperature, and at the same time can improve the relative humidity of the air, reduce dust, purify the air; this spray fan is the use of centrifugal force to produce droplets, so it is called centrifugal spray fan.
B: High-pressure nozzle spray fan Water in the role of high-pressure pumps, with dozens of kilograms of pressure, through high-pressure nozzles to produce a micro-mist, droplet diameter of less than 10 microns, so the evaporation surface area is greatly improved, the micro-mist blown through the powerful fan airflow, greatly improving the liquid surface wind speed, accelerating the diffusion of gas molecules, so the evaporation of water is greatly improved, the water evaporates in the process of water Absorption of heat in the process of evaporation of water, reduce the temperature, and at the same time can improve the relative humidity of the air, reduce dust, purify the air; this fan is through the use of high-pressure nozzles to produce a micro-mist, so it is called high-pressure nozzle spray fan.

Evaporative spray cooling fan introduction:
Traditional air conditioning energy consumption, high operating costs, which to some extent limits the purchase volume. Our evaporative spray cooling fan, reflecting the energy saving, human nature, beautiful, environmentally friendly and other characteristics, for electronics, textiles, shoes, plastics, machinery workshop, cigarette factory, modern home gentleman, office, supermarkets, hospitals, casinos, waiting rooms and other environments of ventilation and cooling to provide a perfect solution.
Evaporative spray cooling fan features:
1, completely environmentally friendly products: it is no compressor, no cold coal, pollution-free environmentally friendly products, which is the use of indoor air evaporative cooling principle of cooling and convective air exchange with the indoor so as to achieve the ventilation and cooling, increase the humidity of the purpose.
2, low operating costs, can quickly recover the investment: compared with the chiller series, power consumption is only 1/2-1/3
3, cooling effect is obvious: in the more humid areas (such as the southern region), generally can reach 5-10 ℃ or so of the obvious cooling effect; in the particularly hot and dry areas (such as the North, Northwest China), the cooling amplitude of about can reach 10-15 ℃. Around.
4, low investment cost, does not occupy the building area: compared with the chiller system, the cost is less than half, and the equipment does not occupy any building area.
5, to keep the indoor air clean, clean, hygienic: doors and windows open for exhaust is a major feature of the evaporative air-conditioner, 100 percent of the fresh air replacement so that people are always in the natural environment, completely free of traditional air conditioning brought about by the sense of discomfort, the dirty air out of the outdoors.
6, easy to maintain and install: the system is simple, easy and fast installation, maintenance, without the need for professional maintenance personnel.
7, to prevent air drying: it can moisturize the skin and have some benefits for the skin.
8, low noise, low vibration
Evaporative spray cooling fan and central air conditioning units, chillers compared to the advantages:
1, evaporative spray cooling fan is the use of water evaporation refrigeration, air distance, air volume, can make the closed place temperature distribution is uniform, and both filtration function. Make the indoor environment comfortable, high oxygen content, fresh air, while the traditional central air conditioning is the direct use of Freon refrigeration, air temperature difference, air volume is small, the room temperature is not easy to uniform. And ventilation function is poor, not suitable for semi-enclosed places, if used for a long time easy to get "air conditioning disease".
2, evaporative spray cooling fan service life than the traditional central air conditioning twice as long, the overall failure rate is low, equipment maintenance is simple and convenient.
3, spray cooling fan than the traditional chiller can be more effective in increasing the environmental humidity, reduce the ambient temperature;
4, the spray fan principle: spray cooling fan there are two ways to **** choose
Spray cooling fan one-time investment in a small, but also the overall operating efficiency, operating costs province, 2000 square meters of space, for example, with the chiller host 20 units, one hour full load calculation, running power for 20KW, and a new generation of spray cooling fan 40 units per hour running power is only 10KW, according to the daily operation of 10 hours a day, you can save 3000-5000 yuan of electricity per month, energy saving up to 50%.
The new generation of spray fan, spray fan, cooling fan, cooling fan is the use of advanced centrifugal secondary atomization principle, so that the water in the rotating disk and fog particles under the action of the spraying device, the use of centrifugal force to make the ultra-tiny droplets up to 10 microns, therefore greatly improving the evaporation surface area; droplets through the airflow by the fan blowing, which means that greatly improves the surface of the liquid wind speed, accelerate the gas The diffusion of gas molecules. Therefore, the evaporation of water is greatly increased, in the process of vaporization of water to absorb heat, reduce the temperature and increase the relative humidity of the air. In the use of the process of no droplet phenomenon, atomization fine, range transport, if used with high-flow axial fan, increase the indoor exhaust volume, improve air flow rate, can further improve the use of the effect. The technology developed faster in South Korea, the end of the nineties began to import our country, the domestic enterprises of some industries began to apply, but its price is very high, so that most enterprises are discouraged. Ltd. after intensive research, finally fully digested and absorbed its original technology, while further improving the original basis of raw materials and processing technology, making the use of the effect greatly improved. Its outstanding advantages are: the structure is relatively simple, a single unit can be used; mobility, more flexible, wider range of applications; because the system does not require high pressure, the cost is lower, but also to avoid the nozzle is easy to clog and so on; at the same time, the cooling speed is faster; do not need to use the environment of the workshop for transformation; because we have been able to mass production, so the price is very low, the products are exported to domestic and foreign; at the same time, because we are At the same time, due to our new technology, making the overall power of the equipment is smaller, so that when the customer is practical, more energy-saving power, single power is only more than 200 watts, saving customers a lot of cost of use, and the failure rate of the equipment is very low, but also for customers to save maintenance costs, improve the actual efficiency of the customer's work.
