The terminal equipment of the fan coil unit, also known as the central air conditioner, is mainly composed of low-noise motors and coil units. The fan cools or heats the indoor air or outdoor mixed air through the surface cooler and sends it into the room to reduce or increase the indoor temperature to meet people's comfort requirements. However, there are many dust particles in the atmosphere. Under the action of long-term suction and return air, the aluminum fins of the fan are covered with dust and dirt. At this time, the heat exchange between the chilled water and the hot air is affected on the one hand, and the air temperature is affected. . Today, let’s take a look at the fan coil cleaning methods and common troubleshooting, and hope to help you.

After the central air conditioner has been used for a period of time (usually 1-2 years), the aluminum fins of the fan must be cleaned. The fan motor and impeller must be removed in the process of cleaning the aluminum fins of the fan. You can also check whether the motor and capacitor are burned out. an examination. When cooling in summer, due to the large amount of condensed water, when it flows into the condensate drain pipe in the tray, it is easy to produce bacteria and algae and block the condensate drain pipe. Therefore, the tray should be cleaned, sterilized and algae-killed.

After cleaning the water collecting pan of the fan coil, perform disinfection and sterilization and dredge the condensate pipe. Regularly place fan coil disinfection and sterilization tablets on the fan coil water collection tray to prevent the tube from being blocked due to the propagation of bacteria and algae. At the same time, the fan impeller, volute, motor, shaft, etc. of the fan coil are removed, washed and dusted. After the fan coil is cleaned, the amount of ventilation is increased, the central air conditioning effect is good, the indoor air quality is good, the noise is reduced, the electricity bill is reduced, and the condensation is smooth.
