Design & Selection
5 Section of FCU
5.1 FCU Type Selection
The air-water fan coil unit is optional for Versati units
5.2 Matching of Capacity
Load of the FCU is better to be between 70%~120% of the Versati unit.
Notes:
①
When load of the FCU is too small, the unit would start/stop frequently, which is adverse for oil return.
②
When load of the FCU is too large, the unit would always run under high frequency, which is unhelpful for
energy conservation.
