Air filter is an important part of the fan coiler used to purify the return air, usually made of chemical fiber material filter or multi-layer metal mesh plate. Due to the location of the fan coiler installation, the length of the working time, the use of different conditions, its cleaning cycle and cleaning methods are different.

In general, during continuous use should be cleaned once a month, if the cleaning work is not timely, the filter mesh of the aperture clogging is very serious, it will make the fan coiler air supply greatly reduced, and its supply of cold (heat) to the room is correspondingly greatly reduced, thus affecting the quality of room temperature control.

Air filter cleaning method should be convenient, fast, small workload point of view, preferred vacuum cleaner cleaning method, the biggest advantage of this method is to clean without disassembling the filter. For those who are not easy to suck clean wet, heavy, sticky dust, should be used to remove the filter with water pressure rinsing or brushing, or brushing with medicinal water cleaning method.

Air filter cleaning is the most frequent fan coiler maintenance work, the largest workload operations, must give full attention and reasonable arrangements.

Second, drip tray
When the coil for air cooling and dehumidification treatment, the resulting condensate will drip in the drip tray (also known as water tray, water collection tray), and discharged through the drain. Fan coil air filter is generally coarse filter, some fine dust will pass through the filter holes and attached to the surface of the coil, when the surface of the coil condensate will be formed when the dust will be brought down to the drip tray. Therefore, the drip tray must be regularly cleaned to clean the dust deposited in the drip tray. Otherwise, too much dust deposited.

1, will make the drip tray of the water capacity is reduced, in the condensate produced a large amount of water, due to drainage is not timely caused by condensate from the drip tray overflow damage to the ceiling of the room accident;

2, will block the drain, the same condensate overflow occurs;

3, will become a breeding ground for bacteria and even mosquitoes, posing a threat to the health of the people in the room.
The drip tray is usually cleaned twice a year, if the air conditioner is used seasonally. The air conditioner is cleaned once at the end of the season. Cleaning is generally done by flushing with water, and the sewage is discharged from the drain. In order to disinfect and sterilize, you can also clean the drip tray and then use disinfectant water (such as bleach) to brush once.

Third, the coil
The coil carries the important mission of transferring the cold (hot) water to the air through the fan coil. In order to ensure efficient heat transfer, the surface of the coiler must be as clean as possible. However, because the fan coiler are generally equipped with coarse filter, the hole is relatively large, in the beginning of the use, it is inevitable that there is dust through the filter and attached to the coiler pipe or rib surface. If not cleaned in time, it will make the coil in the cold (hot) water and the coil outside the flow of air between the heat exchange is reduced, so that the heat transfer efficiency of the coil can not be fully realized. If there is a lot of dust attached, and even part of the air channel between the ribs are blocked, it will also reduce the air supply of the fan coiler, so that its air conditioning performance is further reduced.

Coil cleaning can refer to the air filter cleaning method, but the cleaning cycle can be longer, generally cleaned once a year. If the air conditioner is used seasonally, it is cleaned once at the end of the air conditioning season. As a last resort, do not use the whole from the installation part of the dismantling of the way to clean, in order to reduce the cleaning workload and dismantling work on the air conditioning caused by the impact.

Fan
Fan coiler is generally used is a multi-blade double inlet centrifugal fan, this fan blade form is curved. As the air filter can not capture all the dust, so the leakage of dust may be adhered to the curved part of the fan blade, making the performance of the fan blade changes, and the weight increases. If it is not cleaned in time, the fan's air delivery will be significantly reduced, the power consumption will increase, the noise will increase, and the overall performance of the fan coiler will deteriorate. Fan impeller due to a worm shell surrounded by, not disassembled to clean the work is more difficult to do. You can use a small powerful vacuum cleaner suction cleaning, general cleaning once a year or an air conditioning season cleaning.
