Fan coils are usually installed directly in air-conditioned rooms, and their service status and quality of service will affect indoor noise levels and air quality. Therefore, daily maintenance and maintenance of air filter, drip tray, coil, fan and other major components must be done to ensure that the fan coil works normally and does not have a negative impact.
The coil is responsible for the important mission of transferring the cold heat of the hot and cold water to the air passing through the fan coil. In order to ensure high efficiency heat transfer, the surface of the coil must be kept as clean as possible. However, since the fan coil is generally equipped with a coarse filter, the hole is relatively large, and at the beginning of use, it is inevitable that dust passes through the filter and adheres to the surface of the pipe or the rib of the coil. If it is not cleaned in time, the amount of heat exchange between the hot and cold water in the coil and the air flowing outside the coil is reduced, so that the heat exchange performance of the coil cannot be fully exerted. If there is a lot of dust attached, even if some of the air passages between the ribs are blocked, the air supply volume of the fan coil is also reduced, and the air conditioning performance is further reduced.
