Fan coil of the first purchase to ensure that their suppliers to provide third-party product performance test reports, and to determine whether the product certification. Certification by an impartial third-party inspection and evaluation by the certification body's quality management system and business type test samples to confirm the company's products, processes or services can meet the standard requirements, the availability of sustainable and stable production in line with standard products. Enterprise through product certification is a manifestation of strength, now the State Certification and Accreditation Administration Committee authorized product certification can be fan-coil unit is China Academy of Building Research, the specific environmental monitoring and control optimization study by the Center to implement.
　　Fan coil is usually mounted directly on the air-conditioned room, it worked and served the state will affect the quality of the noise level and indoor air quality. Therefore, we must do air filters, drip trays, coils, fans and other major components of the routine maintenance worked to ensure the fan coil to function properly, do not have a negative impact.
　　Hot and cold water fan coil will be responsible for heat transfer to the cold air through the fan coil of an important mission. In order to ensure efficient heat transfer, requiring the surface of the coil must try to keep clean. However, due to fan coil units are generally equipped with coarse filter, bigger hole, at the beginning of use, it is inevitable that dust through the filter and attached to the coil of pipe or fin surface. If not clean, it will make the coil in the hot and cold water and drain off the air coil heat exchange between the reduced, so that the heat exchanger coil performance can not be fully realized. If you attach a lot of dust, and even some air between the fin channel blockage, then the coil while also reducing the amount of air to further reduce air-conditioning performance. Fan coil cleaning methods can refer to the air filter clean way, but the cleaning cycle can be longer, usually cleaned once a year. If the seasonal use of air conditioning, air conditioning use in the cleaning time after the end of the season. A last resort, do not use the whole site removed from the installation clean way to reduce the amount of cleaning and disassembly worked worked impact
