Indoor thermal environment control based on thermal sensations

According to the existing problems including unreasonable set point of indoor temperature resulting overcooling or overheating and energy waste at present, puts forward a new concept for indoor thermal environment control. Occupants can input their thermal sensations, such as hot, cold, dry and humid through a human-machine-interface, and the control system can adjust the thermal environment accordingly. In order to verify the feasibility of the proposed system, builds an experimental test bed and carries out the experiments. The result shows that the room occupants evaluate the control system with a score between 6 and 7, i.e. “satisfied” and “very satisfied”, which means that the proposed control system is feasible for practical applications.
