Performance Characteristic Charts
Actual performance can be determined by conducting correction after looking up the following charts.
Based on the ambient temperature and desired return water temperature, we can locate the corresponding
performance factor in these charts, then the corresponding actual cooling (heating) capacity and power input
can be determined by using the following formula.
Actual cooling (heating) capacity = nominal cooling (heating) capacity * cooling (heating) performance
correction factor
Actual power input = nominal power input * power input correction factor.
