5.2.2 Displaying the cold-cap./heat-cap.-value

Press
- Depending on the setting of the unit, the cold-cap./heat-cap.-
value is displayed for the ideal comparison process by the
2 2 . . 6 6 7 7
Carnot or Lorenz method (see 5.3.11 System options,
refrigeration system or heat pump, P. 17).
Single-component and azeotropic refrigerants are calculated by
Carnot and non-azeotropic refrigerants by Lorenz.
If the pressure values are not plausible (e.g. same pressure at the
high and low pressure sides),
Cold-cap.-values for the ideal comparison processes are not
suitable for comparisons between different systems. However,
they are useful for comparisons in one system at different
times, e. g. during commissioning or before and after
maintenance.
