Real-time determination of optimal indoor-air condition for thermal comfort, air quality and efficient energy usage

摘要: Abstract For building, “surroundings” that effect on indoor-air condition change with respect to the time. Without proper determination of desired heating, ventilating and air-conditioning (HVAC) system, it may not be feasible provide simultaneously occupants thermal comfort acceptable air quality efficient energy consumption all This paper presents an alternative methodology real-time optimal for HVAC system in order achieve such total requirements. Predicted mean vote (PMV), CO 2 concentration cooling/heating load are used as parameter indices comfort, respectively. The performance index is then defined by summation terms square errors between those actual their values. systematically minimized a gradient-based technique yield system. A case study was chosen 24 h operating single-storey building determining temperature, humidity, velocity, air-ventilation rate. experiment results show proposed can efficiently implemented maintains PMV close levels less when compared from conventional approach.
