Do you know the maintenance and overhaul of the condenser?
Details
Surface cooler is also called condenser or surface cooler and coil. Generally divided into two types: first, the heat exchanger of fan coil unit, whose performance determines the capacity of fan coil unit to transport cold (heat) and its influence on air volume. This equipment is commonly found in air conditioners. Second, the air-cooled fin condenser in the air-conditioning unit ensures the disturbance of air heat exchange and makes it in turbulent state, which greatly improves the heat exchange efficiency. The aluminum fin of the surface cooler has undergone three strict cleaning procedures in the factory, including metal cleaning agent, ultrasonic cleaning and rinsing with clear water, which ensures that there is no residue on the fin, makes the air circulate more smoothly, and fundamentally guarantees the reliability of heat exchange. Maintenance and overhaul of surface cooler have the following places 1 fan coil units are usually installed directly in air-conditioned rooms, and their service status and service quality will affect indoor noise level and air quality. Therefore, it is necessary to do a good job in daily maintenance of main components such as air filter, drip tray, coil, fan, etc., so as to ensure the normal operation of fan coil without negative impact. Coil 2: The coil is responsible for transferring the cold heat of hot and cold water to the air passing through the fan coil. In order to ensure efficient heat transfer, it is required that the surface of the coil must be kept as smooth as possible. However, since fan coils are generally equipped with coarse filters with large holes, it is inevitable that dust will pass through the filters and adhere to the surfaces of pipes or fins of the coils at the beginning of use. If it is not cleaned in time, the heat exchange capacity between cold and hot water in the coil and the air flowing out of the coil will be reduced, and the heat exchange efficiency of the coil will not be brought into full play. If there is a lot of dust attached, and even some air passages between the fins are blocked, the air supply volume of the fan coil will be reduced at the same time, which will further reduce its air conditioning performance. 3. The cleaning method of coil can refer to the cleaning method of air filter, but the cleaning cycle can be longer, generally once a year. If the air conditioner is used seasonally, clean it once after the air conditioner usage season ends. Unless it is absolutely necessary, do not use the method of removing the whole from the installation site for cleaning, so as to reduce the amount of cleaning service and the impact caused by disassembly and assembly service.
