It is common for the condensate pipe of fan coil units to be blocked, mainly due to the presence of water in the fan coil units of hotel rooms. In addition, the temperature is suitable, which can increase the growth of algae and plants. The fan coil units cause a thick residue of gel like material that slides and blocks the condensate pipe. Overseas, algae killing drugs are often placed in the water storage tray of hotel room fan coil units to reduce their damage. Water seepage outside the water storage tray of the fan coil unit is mainly due to insulation issues. Strengthening insulation can remove it; If the condensate pipe of the fan coil unit is not smooth in the water storage tray, it is caused by the overflow of condensate water. The method of connecting the condensate pipe is usually to prepare a 4-5 meter long plastic hose in advance, insert one end into the condensate discharge pipe, and connect the fan coil unit to the bathroom tap water fan coil unit. A small connector can be made by screwing it onto the tap water fan coil unit with an external thread, and use the pressure of water to clear the sewer, fan coil unit or blow it with a carbon dioxide cylinder.

The key to the fan coil unit is the mandatory effect of the centrifugal fan, which heats the gas according to the appearance of the electric heater. Therefore, the heat convection heat exchanger between the heat pipe radiator and the gas is strengthened, and the fan coil unit can quickly heat the gas in the room. Fan coil unit is the tail equipment of air conditioning unit. The principle of fan coil unit is to continuously circulate the gas in the room inside the generator set, so that the air is cooled after passing through the cooling water fan coil unit to ensure the stability of the room temperature. Usually, the fan coil unit is sent into the room after being solved by the fresh air unit to achieve the necessary exhaust air volume for the central air conditioning room. However, because heating methods such as fan coil units only rely on convective heat transfer, which results in a lower level of comfort in the room, they are only suitable for venues where people stay for a shorter period of time, such as fan coil unit company offices and hotels, and not for ordinary housing. Due to the increase in centrifugal fans, the project cost and operating expenses have been raised, and the maintenance and supervision of fan coil units are also relatively complicated.
