PERFORMANCE ANALYSIS - HEATING EFFICIENCY OF SUPPLEMENTARY BANK
Graph 3
gives an analysis of the cooling performances in operating conditions differing from the nominal ones. The
values given refer to the maximum fan speed. The values corresponding to the medium and minimum speeds can
be found by applying the corresponding corrective coefficients given in the table below.
DATA CORRECTION COEFFICIENTS
If the unit operates at the same temperature as the inlet water, the water flow rate is envisaged at maximum speed.
The efficiency ratings obtained at speeds differing from the maximum one are calculated according to the following
corrective coefficients:
