Fan disk pipe unit referred to as fan tray.It is one of the end devices of the air -conditioning system composed of small fan, electric motor and tray (air heat exchanger).When frozen water or hot water flows in the tube, the air extends with the air from the outside of the tube, causing the air to be cooled, dehumidifying or heating to adjust the indoor air parameters.It is a commonly used device for cooling and heating.
Classification and characteristics of fan coils
According to the structure, it can be divided into: vertical, horizontal, wall -mounted, card types, etc., of which the vertical formula is divided into columns and low type; according to the installation method, it can be divided into bright and dark installations;It is left and right.The wall -mounted fan dish unit is all in the lightweight units. The structure is compact and good, and it is hung directly above the wall.The card -type (ceiling embedded) units are more beautiful and exposed to the ceiling. The wind turbine, motor and tray are placed on the ceiling, which belongs to the semi -mounting unit.The Mingjian crew has a beautiful shell, bringing in the air inlet and outlet, and installation in the room in the room.The shell of the dark -loading unit is generally made of galvanized steel plate.The national standard "Fan Duan Pipe Unit" (GB/T19232-2003) [2] stipulates that the fan disk pipe crew is divided into two categories according to the static pressure outside the machine: low static pressure type and high static pressure type.The export static pressure of the low static pressure unit at the rated air volume is 0 or 12Pa, and the export static pressure is 0 for the crew of the air outlet and filter;The export static pressure of the static pressure unit at the rated air volume is not less than 30Pa.
Winder plate pipe selection and installation requirements
The fans should choose light or dark in accordance with the specific conditions and decoration requirements of the room to determine the installation location and form.The vertical unit is generally placed under the windowsill of the outer wall; the horizontal units are hung on the upper part of the room; the wall -mounted unit is hung above the wall;Essence
The Mingjian unit is placed directly indoors without the need to decorate, but the units that coordinate the appearance of the appearance and the room color of the room should be selected;filter.There should also be demolished or open maintenance ports during building decoration to facilitate the disassembly and maintenance crew fans and motors and cleaning air heat exchangers.
Most of the horizontal installation units are hidden on the ceiling, and there are two ways of sending the air supply: the top side of the top side of the top shed to send the wind.If the side delivery method is adopted, a low -static fans can be selected, and the outlet of the unit can be directly connected to the double -layer shutter.The air ducts, the top of its rolling device is sent down the air.There are two ways to return air in the horizontal dark installation crew: setting a shutter or other form of air outlet and air outlet filter on the ceiling, and the air ducts receive the crew of the crew, without a duct, indoor air into the ceiling, and thenThe crew placed on the ceiling inhaled.
In addition, when choosing a fan coil, you should pay attention to the requirements of the room for noise control.
