Installation and structure of fan coil

1. The installation location of the air-conditioning host should be convenient for maintenance and does not affect its use function, especially pay attention to heat dissipation. When there are multiple hosts in the computer room, all hosts must take over the direction and operating surface in the same direction.

Use and control principle of horizontal fan coil

The main control parameters of horizontal concealed fan coil unit are rated air volume, outlet static pressure, input power, rated cooling capacity, rated heat supply, noise, water resistance, etc. For the fan coil unit of double-pipe water system (suitable for air conditioning system that only converts heating or cooling according to season or air conditioning area), only one set of coil units are configured, and both heating and cooling in winter and summer are equipped, for fan coil units of four-pipe water system (applicable to air conditioning systems with frequent heating/cooling conversion), a combined type of heating and cooling coils shall be configured.

Fan coil plus fresh air system and dust influence

The fresh air system can still introduce outdoor fresh air under the premise of not opening windows for 24 hours to eliminate indoor turbid and harmful air. The fresh air system consists of a fan, an air inlet, an air outlet and various pipes and joints. The fan installed in the suspended ceiling is connected with a series of air outlets through pipes. The fan is started. The indoor polluted air is discharged to the outside through the air outlet and the fan to form negative pressure in the room, outdoor fresh air will enter the room through the air inlet, so that indoor personnel can breathe high quality fresh air, which is the fresh air system.

Fan Coil Cooling Heating Process and Common Faults

The fan coil is mainly composed of a fan, a heat exchange coil and a casing. According to the external static pressure of the fan coil machine, it can be divided into standard type and high static pressure type. According to the number of heat exchange coil rows, it can be divided into two rows and three rows. The heat exchange coil generally adopts copper tube string aluminum fins. The outer diameter of the copper tube is 10~16mm, the fin thickness is about 0.15~0.2mm, and the spacing is 2.0~3.0mm, the motor adopts capacitive 4-pole single-phase motor, three-speed speed, and the casing and condensate plate are insulated.
