Developing a collaborative control strategy of a combined radiant floor cooling and ventilation system: A PMV-based model

The development of collaborative control strategies for radiant cooling and ventilation systems improves thermal comfort energy efficiency. This study used the Transient System Simulation (TRNSYS) tool integrated with parametric simulation manager jEPlus to determine optimal starting operation mode a combined floor (RFC) system. results were validated by an experiment. optimization process was constrained defined predicted mean vote (PMV) objective minimizing consumption. showed that system started 1 h earlier than RFC at initial indoor humidity 85% prevent condensation, whereas both same time 75% in stage. In stage, self-regulation potential adjustment capacity coordinated counter dynamic internal heat gains. Moreover, proportion total sensible removed (Sv/SR) positively correlated Sv/SR must be sufficiently high large PMV deviation from zone ?0.5 0.5. A strategy using PMV-based model proposed adjust according range, resulting highly efficient maximum savings 26.2%.
