In-Depth Information
When analyzing Figure 13, one conclusion is inferred, the dominant recovery system is
the evaporative cooler. This factor can be easily explained taking into account its location
within the test ring where the heat pipes battery works with lower temperature differences
during its operation cycles.

Evaporative cooling system
In this subsection a detailed analysis for the evaporative cooling system was carried out.
Firstly, the corresponding results for both working modes are shown ( See Figure 14 and 17
and Tables 9-10), and secondly, these results are studied separately for heating mode
(See Figure 15 and 18 and Tables 11 and 13 ) and cooling mode (See Figure16 and 19 and
Tables 12 and 13).
