Fan coil is usually installed directly in the air-conditioned room, and its service status and service quality will affect the indoor noise level and air quality. Therefore, it is necessary to do the daily maintenance of the main components such as air filter, drip tray, coil, fan, etc., to ensure that the fan coil plays a normal role and does not have a negative impact. Next, Kunshan central air conditioning maintenance take us to take a look at the Jingle central air conditioning maintenance network of small series of documents.

The coil is responsible for the transfer of cold heat from hot and cold water to the air passing through the fan coil. In order to ensure efficient heat transfer, the surface of the coil must be kept as smooth as possible. However, because the fan coil is generally equipped with coarse filters, the holes are relatively large, and it is inevitable that dust will pass through the filter and adhere to the pipe or fin surface of the coil when it is first used. If it is not cleaned in time, it will reduce the amount of heat exchange between the cold and hot water in the coil and the air flowing through the coil, so that the heat exchange efficiency of the coil can not be fully played. If there is a lot of dust attached, and even part of the air passage between the fins is blocked, it will also reduce the amount of air sent by the fan coil, and further reduce its air conditioning performance.

The cleaning method can be referred to the cleaning method of the air filter, but the cleaning cycle can be longer, and it is generally cleaned once a year. If the air conditioner is used seasonally, clean it once after the end of the air conditioner season. Less than a last resort, do not use the whole disassembly from the installation part to clean, in order to reduce the amount of cleaning and disassembly service caused by the impact.

After the fan coil is used for a period of time, dust and bacteria will accumulate between the fins and the impeller. When the dust reaches a certain thickness, the heat dissipation effect of the fins will be affected, resulting in the room temperature not meeting the requirements. In addition, the fan coil that is not cleaned for a long time will breed a variety of bacteria, which will cause diseases on the human respiratory tract. Therefore, it is recommended that the central air conditioning maintenance fan coil should be cleaned regularly.

Cleaning significance:

1. Remove bacteria and dust in the delivery and return air system to improve indoor air quality;

2, reduce the wind resistance of the variable air volume air conditioning unit, improve the heat exchange efficiency, increase the air supply, save energy;

3, regular fan coil system maintenance, prolong the service life of the unit;

4. Reduce operating costs and enhance asset value;
