Influence of PMV-based control on energy consumption and thermal comfort during heating period in a highly glazed room

Abstract : This paper investigates the energy saving potential of a PMV-based thermal comfort control in a highly glazed room during the heating period. For the analysis, a PMV-based thermal comfort controller model is implemented in a validated Dymola® model to carry out the simulations. The results show that, PMV-based control provides consistent thermal comfort as well as energy-saving improvement. A parametric study is performed to investigate the effect of glass façades area and type on thermal comfort and energy saving. The results show that both thermal comfort and energy-savings could be improved under adequate glass façade configuration. Finally, a sensitivity study using the Design of Experiment (DoE) method is performed to study the effect of different parameters on the energy consumption in a PMV-based controlled space. Results demonstrate that energy consumption is highly sensitive to the metabolic rate, the mean radiant temperature and the clothing insulation more than those of the other parameters.
