FP-KM card type fan coil unit

Fan coil units are mainly composed of centrifugal fans, coil heat exchangers, etc., and are the end devices of central air conditioning systems. They are widely used in air conditioning fields of multi room or large space industrial and civil buildings such as hotels, restaurants, factories, hospitals, exhibition halls, shopping malls, and office buildings to meet the requirements of cooling, dehumidification, heating, etc., and create a fresh, peaceful, and spring like working and living environment for people all year round.

Our company's fan coil units have undergone design optimization, resulting in significantly improved coil performance. The coil units are divided into two types: high-efficiency and standard; The standard fan coil unit can meet the various parameters required by the national standard, while the performance parameters of the high-efficiency fan coil unit are more than 20% better than the national standard requirements.

The FP-KM card type exposed four outlet fan coil unit can be ideally placed in the ceiling, combined with indoor decoration, with only the air outlet exposed outside the ceiling. The air outlet is beautiful, does not take up space, and is easy to maintain.

DC brushless fan coil unit

Using a brushless DC motor to achieve diversified control of high, medium, and low speed regulation, as well as stepless speed regulation.

1. The working speed range is wide, which can meet the speed requirements of various air volume modes.

2. As the motor speed decreases, the air volume also changes, which reduces energy consumption and achieves energy-saving effects.

Waterway control system

The two-way or three-way on/off type waterway control system includes electric actuators, valves, and related components. The control system is directly installed by the factory on the coil unit with an extended water tray, and achieves automatic indoor temperature adjustment by controlling the opening and closing of the cold or hot water system.

1. Easy to install, only need to connect the water pipe and power supply on site, and it can be put into use.

2. Compact design, fully utilizing the extended water tray space, without the need to change the size of the unit.

Characteristics of FP-KM card mounted four outlet fan coil unit

1. Safe and reliable, with a long lifespan.

Each coil heat exchanger undergoes pressure leak detection; Inlet and outlet connection (the water collection head adopts forged brass structure, reliable and durable); The condensate tray is treated with spray coating, which does not rust, and all materials are made of imitation active type; The electric motor adopts ultra-low noise rolling bearings, which do not require users to refuel or repair, and the service life can reach 35000 hours; The slender shaft diameter of the electric motor has undergone special treatment and is rust free.

2. High efficiency, energy group

The fan coil unit adopts seamless copper tube series with funny double flanged aluminum ribs tightly integrated, with high heat transfer efficiency and abundant cold (heat) capacity. The standard coil unit can meet the performance requirements of the national standard, and the high-efficiency coil unit has reached the leading level in various regions.

3. High air volume and low noise

The fan coil unit adopts an ultra wide angle volute shell and steel plate multi blade centrifugal impeller. The impeller and motor can be matched with multiple priority options to meet the needs of various specifications of the fan coil unit.

4. Flexible selection

Considering the unique characteristics of installation sites and site limitations, our company provides water trays of different lengths for customers to choose from.

1. Standard water tray - reduces the required installation position, especially suitable for places with limited installation space.

2. Extended water tray - can better catch valve leaks and condensed water.

Installation and usage instructions for fan coil units

1. The fan coil unit shall be installed on a horizontal plane, kept vertical and not tilted; When installing a horizontal unit, the four lifting points must be kept level to prevent one end of the condensate pipe from rising and causing condensate overflow.

2. Valves should be installed on the inlet and outlet water pipes for easy adjustment and maintenance, and attention must be paid to the cleanliness and insulation of the inlet and outlet water pipes. The plastic pipes for condensate water should not be biased or have dead bends to ensure smooth condensate water flow during use.

3. The three speed control switch of the unit should be turned on from the start, and then other levels should be selected. When multiple machines are shared, single machine control is necessary.

4. Power supply for the unit: The single-phase 220V ± 10%, 50Hz AC motor casing should be equipped with a grounding wire. If there are difficulties in starting the unit, it is necessary to check whether the power supply is normal and whether the wind turbine is in contact with the fan volute. When installing the unit, attention must be paid to not damaging the casing, heat exchanger fins, and fan to avoid affecting the appearance and performance.

5. The temperature of the cold water supplied by the unit in summer shall not be lower than 7 ℃, and the temperature of the hot water supplied in winter shall not be higher than 80 ℃. When using cold and hot water, softening treatment must be considered based on the local water quality.

6. The unit is allowed to use a pressure greater than 1.6MPa.

7. The filter should be regularly cleaned to maintain cleanliness and ensure good heat transfer.

8. After connecting the power supply, the fan should be started first to observe whether its rotation direction is correct.

9. If the unit is installed in a dark place, it should be equipped with maintenance doors for year-round maintenance.

10. The unit should cut off the power supply during maintenance.

11. The installation and use of cassette fan coil units are detailed in the accompanying manual.

12. With the continuous improvement of our factory's technical level, we have the right to change the product specifications. If the performance parameters of the unit are changed, the random technical documents shall prevail without further notice.
