Horizontal Concealed Fan Coil Unit

Applications

As an essential terminal equipment in central air conditioning HVAC system, horizontal concealed fan coil unit is the terminal ambient air heat exchanger of central air conditioning system, and the function of ceiling concealed fan coil unit is to heat or cool the indoor environment.

Horizontal concealed fan coil units are the most durable series of all fan coil units. Adequate air volume, high heat exchange efficiency and ultra-thin fuselage structure are very popular in the market. The chilled water horizontal concealed fan coil unit in ceiling is hoisted inside the ceiling, which does not occupy other indoor decoration space and is very convenient to install.

Horizontal concealed fan coil units are widely used in air-conditioning occasions of industrial and civil buildings with multiple rooms or large spaces, such as hotels, restaurants, factories, hospitals, exhibition halls, shopping malls and office buildings, to meet the needs of cooling, dehumidification and heating. This type of fan coil unit can also be applied to the heating of agricultural greenhouses in winter and the cooling and heating of animal husbandry.

As the overall performance of advanced fan coil units is enhanced, it is suitable for high standard people and some quality-oriented customers. It can also be used in some harsh environments, and the enhanced performance makes the durability of the machine better than that of standard machines. Such as in the bathroom. The waterproof function of high-end motor is better than that of standard fan coil units, and its service life is greatly increased.

Working principle

The function of concealed fan coil is to cool or heat indoor air or outdoor mixed air through surface cooler and then send it into the room, so that the indoor air temperature can be lowered or raised to meet people’s comfort requirements. Cold (hot) medium water in the coil pipe is supplied centrally by the machine room.

Product Features and Advantages of fan coil unit fcu

 

Advantages of sheet metal shell: The shell sheet metal is all made of flower-free and oil-free hot-dip galvanized sheet, which is clean and tidy with high durability.

 

 

 

 

 

Advantages of sheet metal processing technology:

1.Longitudinal stiffener technology is added to sheet metal shell of water cooling section to increase sheet metal strength. The screw hole is stretched and plated, and the sheet metal connection is firmer.

 

 

 

 

 

2.The perforated parts of sheet metal copper pipes on both sides of the condenser are stretched to protect the copper pipes from being scratched. Stretching technology is added to the installation part of water collecting head to increase the strength of sheet metal and avoid screwing the water collecting head to damage the pipeline during installation.

Material advantages of condenser

 

 

The fan coil adopts hydrophilic aluminum foil and pure copper tube, the same as those of first-line brands.

 

 

 

 

Advantages of condenser processing technology

Aluminum foil: fully automatic fin grinding tool, fin spacing of 2mm.

Copper pipe: automatic pipe bender to ensure the stability of copper pipe thickness.

Tube expanding: vertical tube expanding machine, can keep the copper thickness unchanged.

Water collecting head: the waterway is designed according to the national water resistance standard. (advanced type is made of brass for forging, which is more strong and durable.)

 

Insulation material for fan coil unit machine

 

 

The front cover of the standard type fan coil units condenser is integrally pasted with 7mm rubber and plastic insulation material, which plays a role of heat preservation when heating, and prevents the generation of condensate water when cooling.

 

 

 

 

Advanced type fan coil unit machines are pasted with tower-shaped silencing cotton. Experimental results show that silencing cotton can effectively reduce 3-5 dB noise.

 

 

 

Advantages of fan and motor section

 

 

 

Fan: galvanized volute with strong corrosion resistance

 

 

 

 

 

 

ABS fan: noise reduction 3-5db.

 

 

 

 

 

Motor：Jiangsu Liwen Motor is selected for the standard type.

 

 

 

 

 

 

Motor:First-line brand Yong ‘an Motor is selected for advanced type.

 

 

 

 

 

The stiffening process of the motor plate increases the strength of the sheet metal, the bending part is stiffened longitudinally, and the surroundingreinforcement ribs are added to the motor mounting hole, which greatly improves the stability of the motor.

 

 

 

 

Longitudinal stiffener，Fan stiffener

Motor surround reinforcement rib

Surround reinforcement ribs for motor mounting holes

Motor board, thickness 1.0mm

The motor board bears the vibration of the fan during operation, so the strength of the motor board is very important.

The air outlet of the fan coil is widened, and the same model is 5CM wider than other products. The purpose is to enlarge the discharge plenum and reduce the noise generated by the wind.
