High Potential of Full Year Operation with Solar Driven Desiccant Evaporative Cooling Systems

The energy saving potential of solar driven desiccant evaporative cooling (DEC) systems are mainly evaluated for the summer period, but not for the winter time. Here, the sorption rotor has high energetically advantages for humidity recovery purposes. The solar driven DEC systems installed in the ENERYbase office building have been monitored within the last two years to analyze also this effect. The primary energy saving potential during the winter time is unexpectedly high due to the humidity recovery mode. Further simulations with different climates using the same system configuration will show the general potential of this effect.
