Fan coil unit is an ideal end product for central air conditioning. It consists of heat exchanger, water pipe, filter, fan, water receiving plate, exhaust valve, bracket, etc. Its working principle is to continuously recycle the air in the room where the unit is located, so that the air is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant.  Usually, fresh air is sent into the room after being processed by the fresh air unit to meet the need of fresh air volume in the air-conditioned room.

With the continuous development of fan coil technology, the field of application has also become larger, and now it is mainly used in offices, hospitals, scientific research institutions and other places.  Fan coil mainly relies on the forced action of fan and achieves the expected effect through the action of surface cooler.  When the temperature difference between the supply and return water of fan coil is constant, the higher the water supply temperature, the greater the reduction in cooling capacity and the reduction in dehumidification capacity.

Fan coil is made of high-quality galvanized plate casing, condensate pan is integrally formed by die pressing process, no welding seam, welding spot and thermal insulation material conforming to fire prevention standard are integrally connected to water pan. Fan coil is small in volume: body design is light and light, drain pipe and wiring are easy to install, left and right connection pipes and return air modes can be changed at any time to match site conditions. Unit can be installed in any space. Fan coil efficiency is high. Advanced tube expansion process ensures close contact between heat exchanger copper pipe and aluminum foil, and heat transfer performance is good.  Low noise of fan coil unit: reasonable design of fan and air flow structure and high-quality sound-absorbing and heat-insulating materials make the unit noise lower than the national standard of 1-3dB (A);  Fan coil unit has low energy consumption: the fan and the heat exchanger are reasonably matched, and the three-speed adjustable air volume enables the fan to use the least electricity. Fan coil unit is widely used as the terminal equipment in the purchase of central air conditioner. The full name of the specification is the fan coil unit of central air conditioner.
