NOMINAL
For
∆
t different to 5°C, use the table
to obtain the corrective factors of the
cooling/heating capacity and input
power.
DEPOSIT FACTORS
11.18.
The performance supplied by the table
refer to clean pipe conditions with
deposit factor = 1. For different deposit
factor values, multiply the performance
table data by the coefficients given.
