The first feeling that fan coil unit brings to people is beauty. After experiencing, it will be found is really comfortable, with soft blowing and no dead corners. FCU operates stably and has very little noise. What is important it has centralized control and is very humanized in design, which is very in line with the living needs of modern people.

With people's understanding of fan coil units and the popularization , there are many people around who use it Suddenly one day, a friend said, why does fan coil units have a musty smell? is there any problem?

The fan coil units are connected by air ducts. They accumulate over time. Without knowing, or if the filter screen of the air outlet is damaged, a lot of dust will enter the air ducts. When the air ducts are wet and mixed with dust, a strange smell will be emitted.

Physical changes have taken place in the fan coil unit blades and a rust smell appears. When the fce is in operation, it will blow out along with the air supply.

Fcu condenser is oxidized by humidity and will also have an increased musty smell when heated.

Another is that the condensate pan of fan coil unit does not drain smoothly. The water pan has accumulated water for a long time, and floating objects in the air fall into it, resulting in bad chemical reaction, some mildew and a musty smell.

If the design of fce condensate pipe is not reasonable, there will also be peculiar smell, especially when condensate water is discharged inside. Sometimes, it will be passed directly into the downcomer, which will bring up the musty smell.

Most of the musty smell  is caused by physical and chemical reasons, not fan coil unit failure, so it is only necessary to find the source of musty smell and clean up the fan coil unit.
