Thermal efficiency, Pressure drop
air side for accessories MBC, SUF
The diagram in fig. 06 allows to determine
the coil thermal efficiency of the
MBC
accessory for each model based on the Td
of the inlet water and Td of the inlet water
air. The corrective factor
to multiply for the
nominal capacity value are present in the
technical data table.
Fig. 07 illustrates the pressure drops (Pa)
on the air side based on the flow rate for
the MBC and SUF accessories
Fig. 08 illustrates the pressure drops (kPa)
water side of the MBC accessory coil.
N.B.:
The pressure drops illustrated in the
diagram also include those of the three-
way valve.
