Shandong Grid Group Co

Our company's horizontal concealed fan coil unit selects the main control parameters: rated air volume, outlet static pressure, input power, rated cooling capacity, rated heat supply, noise, water resistance, etc. For double-pipe water systems (applicable to air-conditioning systems that switch heating or cooling only according to seasons or only according to air-conditioning zones), the fan coil unit is only equipped with one set of coils for both winter and summer heating/cooling models. For four-pipe water systems (suitable for air-conditioning systems with frequent heating/cooling switching), the fan coil unit should be equipped with a combined model with two sets of heating and cooling coils.

Products Key points for selection
The main control parameters for unit selection are rated air volume, outlet static pressure, input power, rated cooling capacity, rated heat supply, noise, new generation horizontal concealed fan coil unit
acoustic 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 subtract 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 unit 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.
