•
It should be mentioned as a general conclusion that level 4 is a discordant point of
the Heating mode behaviour.
•
The dominant recovery system is the evaporative cooler in terms of total heat
recovered.
Sensible Heat
•
Temperature is the most contributory factor in terms of sensible heat. A decreasing
trend is clearly observed from positive values (heating mode) to negative ones
(cooling mode).
Latent Heat
•
Heating mode: temperature was the most contributory factor.
•
Cooling mode: an important by-pass effect was found.
