Introduction to the main functions of air-conditioning centrifugal fans

Before installing the fan, first check whether the various components of the fan are complete. If the user finds that the fan itself is not completed and lacks parts during the installation process, it will definitely have a great impact on the installation process, so we are working on the fan. When installing, you must carefully check the integrity of the fan, including whether the fan is deformed or damaged, or the solid parts are loose. During the inspection process, it must be checked by the user in detail. It is the impeller part of the fan. If the impeller is found to be rubbed before installation, it must be replaced in time to ensure the installation quality of the fan. Prepare each component in advance according to the installation instructions. The installation process is also user-friendly.

Installation knowledge needs to be stored in advance by the user. One thing that is most easily overlooked in Chinese is the installation manual that comes with the fan package. It is best to read the installation manual well, which can also help users further understand the components Each of the models can speed up a lot of progress for installation.

There is one more important point. In the installation, some devices of the fan must be installed, so as to effectively ensure the safety of use and prevent the occurrence of safety accidents. Be sure to ask professionals to install and wire, and avoid random wiring; do not load the overlapping weight of the pipes on the parts of the fan. The air ducts connecting the inlet and outlet of the fan are all supported separately. If users follow these methods to complete the entire installation process of the fan, I believe that the problems in use will be reduced a lot.

Since the function of the fan cannot be replaced by other equipment, the amount of use of the fan in the country is very large, and it involves almost all occasions. Not only that, even some equipment also needs the auxiliary use of the fan to achieve the effect. This is a typical example, but most of the air conditioners use centrifugal fans. The use of centrifugal fans allows the air conditioner to achieve maximum value. This has also greatly increased the usage and scope of the fan, but what role does the centrifugal fan play in the use of air conditioners? (Guide: Ten simple deburring methods, there is always one suitable for you!)

The reason why air conditioners use centrifugal fans cannot be explained clearly at once, but it is still necessary to tell users the most basic common sense content. The high-temperature and high-pressure refrigerating steam from the compressor enters the condenser through the high-pressure hose. The outside temperature is lower than the temperature of the refrigerant entering the condenser. With the help of the condensing fan, most of the heat of the refrigerant flowing in the condenser is taken away by the air outside the car, so that the high-temperature and high-pressure gas is condensed into a high-temperature and high-pressure liquid. When this high-temperature and high-pressure liquid flows through the throttling expansion valve, due to the throttling effect, the volume suddenly increases and the pressure is reduced, and it becomes a low-pressure and low-temperature mist liquid that enters the evaporator and vaporizes at a constant pressure. Because the refrigerant vaporizes in the tube The temperature at the time is lower than the circulating air in the car outside the evaporator tube, so it can absorb the heat in the air outside the tube, so that the temperature of the air flowing through the evaporator is reduced, resulting in a cooling effect, and the vaporized refrigeration vapor is compressed The machine sucks and compresses and turns into high-temperature and high-pressure gas, completing a refrigeration system cycle.

Air conditioner centrifugal fan is mainly composed of two parts: outdoor unit and indoor unit. The outdoor unit is responsible for cooling or heating, and the indoor unit is responsible for transporting cold or hot air to the room, and transporting indoor hot or cold air to the outdoors through pipes to achieve the effect of cooling or heating.

It is not difficult to see from the realization principle of the above air conditioner that the centrifugal fan is undoubtedly the biggest contributor to the air conditioner's ability to exert such a large effect. However, due to the big difference in the model of air conditioner, it is not All air conditioners use centrifugal fans, and some air conditioners use axial fans to achieve the greatest effect than centrifugal fans.
