5.5 Energy recovery data
Reference conditions
See section
Reference conditions and limitations.
Effective working pressure
Consult section Compressor data for the normal working pressure.
Maximum allowed pressure of the heat exchanger
Reading settings
In addition to other data, the following temperatures can be read on the Elektronikon display:
For air-cooled units:
• The water inlet temperature of the energy recovery system
• The water outlet temperature of the energy recovery system
For water-cooled units:
• The water inlet temperature of the energy recovery system
• The water outlet temperature of the energy recovery system
• The cooling water outlet temperature of the compressor
Modifying settings
If the programmed warning settings for the water temperatures are exceeded, a warning indication is shown on
the Elektronikon:
To modify a setting, consult section
Settings menu.
Recoverable energy
The recoverable energy can be calculated from:
RECOVERED ENERGY (kW) = 4.2 x water flow (l/s) x water temperature rise (°C)
In the tables below, typical examples are given, except for the recovered energy.
