Refrigeration & Air-Conditioning
Refrigeration technology is widely used in cooling towers, with fans playing a fundamental role. In the cooling tower, timely discharge of vaporized cooling medium is crucial for reducing the temperature inside the tower, which can maximize the cooling effect of the cooling medium. This is also one of the important conditions that affect the working efficiency of the cooling tower. The refrigeration technology in the cooling tower is mainly achieved by evaporating the cooling medium. When the cooling medium is heated by an external heat source, it will vaporize and absorb heat, thereby lowering its own temperature. At this point, the function of the fan is to timely discharge these vaporized cooling media outside the tower to maintain stable temperature inside the cooling tower. By ensuring the smooth discharge of the cooling medium and stable control of the temperature inside the cooling tower, we can have a significant impact on the cooling effect of the cooling medium. This not only improves the working efficiency of the cooling tower, but also extends its service life and reduces maintenance costs. In summary, the application of refrigeration technology in cooling towers is of great significance for improving cooling effectiveness and work efficiency. By optimizing the design and operation of fans, we can better leverage the role of refrigeration technology in cooling towers, achieving more efficient cooling and energy utilization.

Data center
Fans play an important role in data centers, mainly used for heat dissipation, air circulation, and energy conservation. As one of the basic components in the data center cooling system, fans generate airflow, transfer the heat generated by the equipment to the heat exchanger, and exhaust the hot air to maintain the normal operating temperature of the equipment. Specifically, the application of fans mainly includes the following aspects: 1. Heat dissipation: The servers and other devices in the data center generate a large amount of heat during operation. If these heat cannot be dissipated in a timely manner, it will lead to an increase in equipment temperature, which will affect the performance and lifespan of the equipment. Fans can achieve fast and efficient heat dissipation by inhaling cold air and expelling hot air. 2. Air circulation: Data centers often have a large number of equipment densely placed, which can easily lead to lack of air circulation. Good air circulation can improve the heat dissipation efficiency of equipment and reduce the formation of local hot spots. Fans can promote air flow through forced convection, ensuring good air circulation throughout the entire data center. 3. Energy saving: Traditional air conditioning systems require a large amount of energy to cool or heat indoor air. Using a fan for heat dissipation can effectively reduce energy consumption. Due to the fact that fans are only used for circulation and heat dissipation, compared to traditional air conditioning systems, they consume less electricity and can save energy costs. In summary, the application of wind turbines in data centers is crucial. It can not only maintain the normal operating temperature of the equipment, improve heat dissipation efficiency, but also promote air circulation, energy conservation, and consumption reduction. With the continuous expansion of data center scale and technological progress, the application of wind turbines will become increasingly widespread.

Fan Renovation
In the fields of refrigeration, air conditioning, and building services, AC asynchronous motors are commonly used to drive fans. However, the efficiency of this method is relatively low, leading to an increase in energy consumption. In order to solve this problem, EC technology is widely used in the speed regulation of AC asynchronous motors, and its performance far exceeds traditional AC and DC speed regulation methods. The Sanmu EC fan has the advantages of simple structure, wide speed regulation range, high speed regulation accuracy, convenient installation and debugging, complete protection functions, stable and reliable operation, and significant energy-saving effects. Therefore, it is necessary to replace inefficient AC fans with efficient EC energy-saving fans without changing the mechanical structure of the original system. Switching to EC energy-saving fans not only benefits environmental protection, reduces operating costs, but also improves comfort. Therefore, replacing AC fans with EC fans has become a trend, which is of great significance for improving energy efficiency and reducing operating costs.

Medical purification
In medical facilities, bacteria, viruses, and harmful substances in the air may pose a threat to the health of patients, so maintaining the cleanliness and purity of the air is crucial. The fan can remove pollutants such as bacteria, viruses, and harmful gases from the air by inhaling and treating it, and then release the purified air. Specifically, the application of fans in medical purification includes the following aspects: 1. Air disinfection: The fan can inhale air and disinfect it through methods such as ultraviolet radiation and ozone to kill bacteria and viruses in the air. 2. Harmful gas treatment: Fans can remove harmful gases such as formaldehyde, benzene, as well as particles and other pollutants from the air, ensuring air quality and cleanliness. 3. Humidity and temperature control: In medical facilities, operating rooms, intensive care units, and other rooms require strict humidity and temperature control. The fan can effectively reduce the temperature and humidity in the room by adjusting the air flow speed and direction, providing a comfortable and safe working environment. 4. Air circulation: Fans can promote air circulation in medical facilities, provide good air circulation and ventilation effects, and ensure that patients and medical staff can breathe fresh air. In summary, fans have a wide range of applications in medical purification, ensuring air quality and environmental cleanliness in medical facilities, and providing safe and comfortable working and treatment environments for patients and medical staff.
