What are the factors that affect medium efficiency filters?

The first factor that affects the resistance of air conditioning filters is wind speed. The higher the wind speed, the greater the resistance of the filter; The second is the pollution caused by dust filtration, where the greater the pollution, the greater the resistance. When the wind speed remains constant, the wind resistance basically reflects the amount of dust collected by the filter.

The resistance of newly installed air filters is called initial resistance, and as the number of adsorbed particles increases, the resistance increases. The increase in wind resistance leads to an increase in wind pressure loss, which reduces wind speed and transmission, increases the transmission power of the fan, and is not conducive to energy conservation. In order to maintain and reduce the increase in wind resistance, it is necessary to frequently replace or clean the air filter of the air conditioner, which increases maintenance costs.

In the daily operation of air conditioning, air humidity is also a factor that affects wind resistance. An increase in humidity can cause dust particles adhering to the filter material to stick together, blocking the flow of air and increasing wind resistance. Therefore, we need to find a balance between the impact of wind resistance, economic costs, and fan energy efficiency, and improve the air conditioning and medium efficiency air filters in the storage room.
