Expected results — 1st level

The main results within the first level are the

. primary energy ratio of an assumed reference system working under the conditions as the installed SHC system ((Equation 2).

Herewith the annual savings of primary energy through the utilisation of the SHC system can be expressed.

Further through the calculated cost per installed cooling capacity ((Equation 4), it will be possible in the following years to draw a learning curve for SCH systems.

3.1. Expected results — 2nd level

The main result within the second level is the calculation of the solar thermal energy which could not be exploited by the SHC system — this shows the “efficiency” of the SHC system ((Equation 12 and (Equation 13, see Fig. 5)
