ETHYLENE GLYCOL SOLUTIONS
Water and ethylene glycol solutions used as a thermal
vector in the place of water reduce the performance
of the unit. Multiply the performance figures by the
values given in the following table.
0-5-10 -15 -20 -25
Freezing point (°C)
Percentage of ethylene glycol by weight
cPf: correction factor cooling capacity
cQ: correction factor flow rate
cdp: correction factor pressure drop
f1 correction factor capacity
fk1 correction factor compressor power input
fx1 correction factor total power input
FOULING FACTORS
The performance data given refer to conditions with
clean evaporator plates (fouling factor=1).
For different fouling factors, multiply the figures in the
performance tables by the coefficient given in the fol-
lowing table.
