Regeneration air temperatures and regeneration operation on days with low irradiance
In contrast to typical design conditions, where outside air enthalpy is higher than
that inside, the measured enthalpy difference between room exhaust air and supply air
is higher on average. The heating energy related to the total produced room cooling
energy results in COPs of 1.13 (see Figure 5.35).
5.2.5 Simulation of Solar-Powered Desiccant Cooling Systems
A complete desiccant cooling simulation tool was developed in the simulation envi-
ronment INSEL to improve the control strategy and to analyse the influence of solar
