Fan coil units are generally used in central air conditioners. Their function is to exchange indoor air, adjust indoor temperature and humidity, and finally reach the comfortable temperature of human body. Do you know what little knowledge fan coil units have? Fan coil unit is mainly composed of surface cooler, water pipe, filter, fan, water tray, exhaust valve and bracket. As the terminal device of the central air-conditioning system, the working principle of fan coil unit is that the air in the room is continuously recycled, so that the air is cooled (heated) after passing through the cold water (hot water) coil unit to keep the room temperature constant. Usually, fresh air is sent into the room after being treated by the new fan unit to meet the needs of fresh air volume in the air-conditioned room. Low running noise. When running in low gear, the noise is generally 30 ~ 40 dB (A). Flexible control, economy and energy saving. The fan speed can be divided into three grades: high, medium and low. The water system pump automatically controls the temperature regulator to flexibly adjust the temperature of each room, and can stop running when no one is indoors. Small in size, convenient in layout and installation, and various forms such as plain horizontal concealed installation, etc. You don't need to specially design space to install them. If the building needs to be expanded, it is easier to increase the corresponding fan coil units. Because the units are scattered, the workload of maintenance management is heavy when there are a large number of units. As long as we clean and maintain it in time, it will bring great convenience to our use.
