Cassette fan coil unit is one of the central air-conditioning terminal units. It is composed of a blower and a coil unit. The air is cooled or heated when passing through the coil unit for supplying cold and hot water to maintain the indoor temperature.

Ultra-high and wide-angle three-dimensional air supply
1. The motor adopts a low-noise three-speed capacitor running motor, and is equipped with imported high-precision ultra-low noise rolling bearings. There is no need for users to add lubricating oil during use, and the service life can reach 42,000 hours. The slender shaft of the motor is specially treated and will never rust. Maintenance is easy.
2. The surface cooler is made of high-quality seamless vacuum annealed fully soft copper tubes and high-quality copper fins. It is produced by special heat exchanger processing equipment. After mechanical expansion, the heat exchange tube and the aluminum fins are tightly combined, to ensure high heat transfer efficiency of the surface cooler.
3. The built-in ultra-small drainage pump (optional) can run for up to 80,000 hours without failure, the piping construction is easier, the drainage is completely clean, and there is no worry of dew.
4. The unit can be equipped with a temperature-controlled three-speed speed control switch and an electric two-way valve, which can adjust the air volume according to the needs to achieve the purpose of adjusting the cooling (heating) volume, thereby saving electric energy. 

The cassette fan coil unit has an ABS panel. The surface of the ordinary fan coil unit is only galvanized sheet. The advantages of the cassette type are mainly beautiful appearance, sound-absorbing sponge inside, low noise, and no other accessories are required.Such as air outlets, metal hoses, etc.

Fan coil units are ideal end products for central air conditioners. Fan coil units are widely used in hotels, office buildings, hospitals, commercial and residential, and scientific research institutions. In order to meet the design and selection of different occasions, the types of fan coil units are: horizontal concealed fan coil unit (with return air box) fan coil unit, horizontal exposed fan coil unit, vertical concealed fan coil unit, vertical exposed fan coil unit , Cassette two-outlet fan coil, cassette four-outlet fan coil and wall-mounted fan coil and so on.

The fan coil unit is mainly composed of low-noise motor, coil and so on. The fan cools or heats the indoor air or outdoor mixed air through the surface cooler and sends it into the room to lower or raise the indoor temperature to meet people's comfort requirements. The cold (hot) medium water in the coil is centrally supplied by the machine room.
The central air-conditioning fan coil unit is divided into five types according to the form: horizontal concealed installation, horizontal exposed installation, vertical concealed installation, vertical exposed installation and cassette type;

According to the thickness, the horizontal fan coil unit can be divided into: ultra-thin type, ordinary type; cassette type fan coil unit

According to whether there is a condensate pump, it can be divided into: ordinary type, luxury type;

According to the static pressure of the unit, the central air-conditioning fan coil unit can be divided into: 0Pa, 12Pa, 30Pa, 50Pa, 80Pa, etc., here refers to the static pressure outside the machine;

The central air-conditioning fan coil unit can be divided into two rows of tubes and three rows of tubes according to the number of tubes; There are also two-pipe and four-pipe points: two pipes, that is, ordinary fan coil units use cold water for cooling in summer and hot water for heating in winter;

The four-pipe fan coil unit is mostly used in some more luxurious places. It can take hot and cold water at the same time, that is, some rooms can be cooled and some rooms can be heated according to needs.
