Description

More people are adopting central modulation and supporting fan coil units due to the energy-saving, environmentally friendly, and comfortable features of central air conditioning. The horizontal concealed fan coil, consisting of a fan and coil, stands out as the most durable in its series. With its large air volume, efficient heat exchange, and ultra-thin profile, it enjoys high popularity in the market. Hidden inside the ceiling, this unit saves indoor space and simplifies installation.

Features and Advantages

• Pressure Retaining Valve: Manufacturers equip horizontal concealed fan coils with pressure maintenance valves. These valves ensure the condenser remains airtight upon delivery and effectively prevent liquid leakage.

• Brushless DC Motor: The standard DC brushless motor, combined with an ABS wind wheel, provides ultra-quiet operation and large air volume in the upgraded fan coil unit.

• Metal Plate: Shougang 1.0 oil-free, flower-free, environmentally friendly hot-galvanized sheets make up the unit. These sheets are galvanized at 80 grams per square meter, offering long service life and high corrosion resistance. Automated molds and computer-controlled sizing ensure precise manufacturing.
• Water Pan Bracket: Manufacturers use a high-gloss spraying process on the sheet metal surface, creating a smooth, non-stick, and corrosion-resistant finish. They bond a 7mm PE thermal insulation layer seamlessly with the water tray, simplifying processing and enhancing aesthetics. This design prevents the leaks common with welded trays and significantly extends the water tray’s lifespan. The water pan’s dimensions cover the pipeline space, ensuring effective water collection.

• Radiator-Fan: The fully automatic fin grinder, featuring a large opening window and a 2mm fin gap, enhances heat transfer efficiency. Advanced mechanical tube expansion technology tightly bonds the copper tube to the fin, boosting performance.

• Turbine: The ABS turbine and volute wind turbine resist corrosion and operate with noise levels 3-5 dB lower than iron turbines.
• Collecting Head: The three-in, three-out water head speeds up water circulation and increases flow. A large handle vent valve offers easy use, and the automatic welding process ensures uniform welding without trachoma bubbles.

• High Flexibility and Low Installation Cost: The lightweight design simplifies the installation of drainage pipes and pipelines. Users can easily adjust the left and right connections and return air direction to match site conditions.

Working Principle

Fan coil units cool or heat indoor or mixed outdoor air by circulating it through a coil, adjusting the indoor temperature to meet comfort requirements. A heat pump or chiller supplies the cold (or hot) water needed for this process.

Application Scenarios

Fan coil units suit a wide range of settings, including hotels, restaurants, factories, hospitals, exhibition halls, shopping malls, and office buildings. They meet the needs for cooling, dehumidification, and heating in various multi-room or large-space industrial and civil buildings.
