In the designed AHU a cooling coil operates also in order to control the humidity ratio. During the summer season, because of the required dehumidification after the cooling coil the air temperature can become uncomfortable (16°C or even less). To avoid discomfort for the occupants, after the cooling coil there is a reheat coil. The reheat coil controls the supply temperature, which should be about 20°C.
The cooling loads are balanced by radiant floors.
Since the building is going to be used for healthcare purposes (in particular for seriously ill people), avoiding discomfort conditions is very important.
I think that in the proposed model I shall consider such a control strategy.
Since reheating causes an energy demand increase, I am wondering whether I could consider it in the baseline model. Shall dehumidification and reheating be modeled identically in the proposed model and in the baseline model?
The baseline system is System 3 – PSZ-AC.
