Gray vertical concealed fan coil unit is a set of fan coil units. This model has an ultra-thin body and does not occupy effective space. The thickness can only be arranged in the wall under the window or in the recess of the decorative board. The two forms of air outlet and front air outlet are suitable for installation in conference rooms, halls, gymnasiums, etc. Key points: A filter should be installed at the water supply inlet of the unit. When flushing the main pipe of the refrigerant water system, sewage is not allowed to pass through the coil. An exhaust device should be installed at the highest point of the coil pipe connection, and a drain device should be installed at the lowest point.
The condensate discharge pipe of the fan coil unit must have a certain slope to ensure that no water accumulates in the drip tray.
Key points for selection
The main control parameters for unit selection include rated air volume, outlet static pressure, input power, rated cooling capacity, rated heat supply, noise, water resistance, etc.
The air supply volume of the fan coil unit is approximately less than the outlet static pressure (the outlet static pressure is greater than the high static pressure type).
The selection of unit specifications should be determined by factors such as the room's cooling and heating load and the heat-humidity ratio of the air
) When the fresh air and room air parameters are of equal enthalpy, the fan coil unit only bears the burden of the building envelope and the heat generated inside the room. Cooling and heating load
) When the fresh air enthalpy value is greater or smaller than the room air enthalpy value, the fan coil unit should add or deduct part of the fresh air cooling and heating load
) When the absolute moisture content of the fresh air is lower than the room air When the moisture content can fully bear the room's wet load, the fan coil can only bear the room's sensible heat load and should be configured according to dry working conditions
) When the room's sensible heat load accounts for a large proportion, the fan coil should be checked through sensible heat balance calculations Manage the air volume of the unit.
When selecting a unit, the deviation between the actual performance and the rated value should be considered and the following characteristics should be paid attention to
) The rated cooling capacity of the unit is generally the test value under the condition of air enthalpy drop
) Single plate The rated heat supply of the tube unit is generally times the rated cooling capacity
