The operating principle of Cixi cold air fan is simple and effective. It sucks indoor hot air into the machine through a fan blade driven by an electric motor, and then is processed by a refrigeration device to blow out the cold air, forming a cool atmosphere. The cooling fan has a unique design, stable operation, low power consumption, and low noise. It can not only effectively solve indoor high temperature problems, but also keep the air moist, providing a pleasant space. The development trend of air coolers is becoming increasingly diverse and intelligent. With the advancement of technology, the appearance design of air coolers is becoming increasingly compact and exquisite, with a fashionable appearance. The introduction of intelligent control systems enables the cold air fan to automatically adjust its operating status based on environmental temperature, achieving the best energy-saving effect. In addition, some air conditioners can also be equipped with air purification functions, which can filter out harmful substances such as bacteria and dust in the air, providing people with a healthier living environment.

In summary, as an important cooling device, air coolers provide great convenience for people's lives and work. With the continuous progress of technology, we can expect the cold air fan to bring more functions and innovation in future development, creating a more comfortable and livable living environment for people.

The difference between industrial large fans and negative pressure fans is that industrial large fans and negative pressure fans have similar functions, that is, cooling and dehumidification. Therefore, people may hesitate to choose which one to choose. In fact, industrial large fans and negative pressure fans have some differences besides similar functions. By understanding the differences between the two, we can choose according to our own needs, What are the differences between industrial large fans and negative pressure fans? The answers provided below are expected to be helpful to everyone.

Differences between industrial large fans and negative pressure fans

1. Installation is different

(1) Installation of industrial large fans. Industrial large fans are generally installed above factories and workshops, which have a wide working range and allow a large portion of the area to be cool.

(2) Installation of negative pressure fan. Negative pressure fans are generally installed outside the workshop window and at the lower air outlet for easy external ventilation.

2. Different principles

(1) Principles of industrial fans. The cooling principle of industrial large fans is that the airflow is pushed from top to bottom in a conical shape towards the ground, and flows horizontally to the ground. When encountering horizontal airflow blocking or adjacent to the fan, it is pushed up to the roof, which can achieve effective all-round overall ventilation and personnel cooling for tall spaces. Unclosed spaces with low environmental requirements can also be effectively cooled.

(2) Working principle of negative pressure fan. Quickly reach a large exhaust volume when the fan is powered on and working. It can quickly create an air pressure difference between the indoor environment and the outdoor environment, forming a strong negative pressure, forcing the dirty and hot indoor air to be quickly discharged from the outdoor according to the flow direction we set, and the indoor air pressure will decrease.

3. Different effects

(1) Industrial fan effect. In terms of personnel cooling. The natural breeze generated by a large energy-saving fan blows on the human body, promoting the evaporation of sweat to carry away heat and cooling the body, bringing a cooling sensation. Usually, this cooling sensation can reach 5-8 ℃. In terms of natural ventilation, industrial fans can accelerate indoor air flow and achieve the effect of natural ventilation; In terms of dehumidification and dehumidification, the dehumidification effect of industrial fans is direct and effective, promoting air mixing throughout the entire space.

(2) Negative pressure fan effect. Due to sunlight shining on buildings, machinery, human bodies, and other heat sources, the temperature in places that require ventilation is higher than outdoors. The negative pressure fan can quickly exhaust the indoor hot air, keeping the room temperature at the same level as the outside temperature, and preventing the temperature inside the workshop from rising. The negative pressure fan only has the function of ventilation and cooling, without the function of refrigeration. Cooling is the feeling of the human body.

4. Different usage locations

(1) Places where industrial large fans are used. Large public buildings such as shopping malls, gyms, stations, airports, etc. promote air circulation, dispel odors, create a comfortable shopping and viewing environment, and increase sales. Moreover, mobile fans in industrial fans can be used in relatively open areas and are also more convenient to use.

(2) Place where negative pressure fans are used. For example, clothing factories, electronics factories, entertainment venues, pig farms, garden flowers, and other enclosed places that require cooling and humidity.

Energy saving and environmentally friendly air conditioners (evaporative air conditioners, water-cooled central air conditioners) may have a longer lifespan and a good cooling effect in the factory, as long as the maintenance method is appropriate. What are the reasons for the frequent occurrence of industrial production fan failures? How should everyone maintain and maintain it?

1. If there is significant environmental pollution around the air conditioning unit, it is recommended to clean the server once or twice a day to ensure that the air conditioning unit is fresh and tidy. It is recommended to use fully automatic function mode for operation.

2. After six months of operation of the unit, the basin and its evaporative substances should be cleaned once, and the pressure during cleaning should not be too high to prevent damage to the cooling water curtain.

3. When stopping use for a long time, in order to avoid damage to the human body and mosquito growth caused by freezing and cleaning, the water inlet valve of the drinking water equipment should be turned off, and the unit should be called into the cleaning method. The remaining water in the water storage tank basin should be drained. When shutting down, the server needs to be tightly covered with a soil net and clamped to prevent residual flowers from blocking the evaporation of substances in the late winter wind and sand.

4. When repairing the air conditioning unit, be sure to turn off the power supply of the control cabinet. Maintenance workers should hang maintenance signs inside the unit to prohibit turning on the power supply.

5. When the unit of the air cooler trips due to a fault, it must first clear the fault and then press and hold the air leakage switch.

6. The first time using it, there is a smell of wood residue, which dissipates after 24 hours of persistent use.

7. Rainproof blinds cannot withstand force, and it is prohibited to use the blinds as support points and move them by hand during use or under this premise.

8. Memory rechargeable batteries need to be carefully replaced after 2 years.

9. The server base should be treated with anti-corrosion and rust prevention measures in 2 years, preferably painted. Regular safety checks should be conducted on the robustness of the main frame every year.
