FCU model selection is related to the use effect of air conditioning and energy saving, etc. No matter whether the fcu model selection is too large or too small, it will cause bad phenomena, so it must be checked before fcu model selection.
FCU type is directly related to the output air volume, cooling capacity, heating capacity, electricity consumption and operation noise of the fan coil unit.
How should I choose the fan coil unit model?  How can we choose the correct fan coil unit model?  The following Yuexin fan coil unit manufacturer will teach you how to select a fan coil unit model.
We have learned that the air volume, cooling capacity and noise of different types of fcu are different. What are the main functions of fan coil units? Cooling and heating.  What is the relationship between cooling capacity and air volume? Therefore, when selecting fan coil units, the indoor air volume needs to be determined first, which needs to be taken into account in combination with the actual situation, such as whether there is a fresh air system in the room and the air exchange rate needs.
In the fcu+fresh air system, the processing mode is the enthalpy value from fresh air processing to indoor. The fcu bears the indoor cooling load.
The calculation method steps given in the air conditioning design of civil buildings are:
1. Draw the intersection point of heat moisture ratio line and 90% relative humidity to determine the air supply status point
2. According to the state point to determine the total air volume, minus the new air volume is equal to the fan coil air volume
3. Select the number of fan coil units according to the air volume.
4. Check the fan coil unit cooling capacity.  In the calculation example given, the checked cooling load is much larger than the indoor cooling load.
There is also the cooling capacity of fan coil units. The cooling capacity can be calculated based on indoor orientation, sunlight exposure and indoor functional requirements.
Fcu model selection method, basic principle of fan coil unit model selection, air volume and cooling capacity, when both cannot be met at the same time, priority should be given to meeting air volume and ensuring sufficient air volume is the first prerequisite.
