How to maintain the fan coil unit ？

Fan coil units in use, maintenance work is primarily timely cleaning and replacing the air filter, single-tube heat exchangers routine maintenance and regular cleaning unit chassis, etc. The purpose is to reduce the failure rate of the unit. Fan coil is usually mounted directly in the air-conditioned room, which served the state and worked to influence the quality of the indoor air quality and noise levels. Therefore, you must do the air filter, drip tray, coils, fans and other major components of the routine maintenance worked to ensure the fan coil functioning properly, does not have a negative impact.

In order to ensure efficient heat transfer requirements of the coil surface must be kept clean. However, since the fan coil are generally equipped with coarse filter, aperture is relatively large, at the beginning of use, it is inevitable that dust passes through a filter attached to the pipe or fin surface coil. If not clean, it will make the hot and cold water in the heat coil and coil outward through the air exchange between the reduction, so that the effectiveness of the heat exchanger coil can not be fully realized. If a lot of dust adhesion, and even part of the air passage between the fins are clogged, it will reduce the amount of air the fan coil to further reduce the air conditioning performance.

Referring way to clean the air filter can clean manner, but the cleaning cycle can be longer, generally cleaned once a year. If the seasonal use of air conditioning, the use of clean time after the end of the season in the air conditioning. Not a last resort, do not clean the whole removed, in order to reduce the impact of the amount of cleaning and disassembly worked worked caused.

After the fan coil used for a period of time, it will accumulate on the fins of the impeller for dirt and germs, when the dust reaches a certain thickness, fin cooling effect will be affected, leading to the room temperature is below standard, in addition to long-term cleaning fan coil breeding ground for a variety of bacteria, these bacteria can cause disease on the human respiratory tract, it is recommended that fan coil should be cleaned regularly, fan coil cleaning meaning lower operating costs and enhance the value of assets; reducing drag VAV unit improve the heat exchange efficiency, increase the amount of air, save energy; clear to send, return air system, bacteria, dust, improve indoor air quality; regular fan coil system maintenance and prolong the service life of the unit.

Maintenance of the fan coil units in use work time cleaning and replacement of air filters, single-tube exchanger maintenance and scheduled cleaning of the unit chassis, in order to reduce the failure rate of the unit.Fan-coil unit is usually mounted directly in the air conditioning room, which serves State and the quality of work will affect indoor air quality and noise level.Therefore must make a good air filter and drip tray, Pan pipes, fans and other major parts of the routine maintenance work, ensure the fan coil unit functioning, does not have a negative impact.

In order to ensure efficient heat transfer, requires the surface must be kept bright and clean.However, due to the fan-coil are coarse filters equipped with holes bigger, when used at the beginning, it is inevitable that dust through the filters attached to the coil pipe or ribbed surface.If not cleaned, to make a coil in the hot and cold water and coil heat exchange reduction between the outflow of air, coil heat exchanger efficiency could exert.If lots of dust, even the air passage between the fins are blocked, also reduces the fan-coil unit air volume, which further reduce air conditioning performance.
