  1. Distinguish occupants from background in an image
    using the Fuzzy C-Means algorithm (FCM)
  2. Distinguish each occupant by locating local
    temperature peaks in the image
  3. Region growing for more accurate segmentation of
    occupants

  • Temperature request and humidity request
    inference
  • TRV error of measured and desired temperature
    together with its deviation
  • HRV foreseen error and deviation
  • Integrated inference
  • If x1 is Ai1, , x5 is Ai5 then y1 is Bi1, , y3
    is Bi3
  • x1 last manipulated variable for the cooling
    valve
  • x2 last manipulated variable for the heating
    valve
  • X3 last manipulated variable for the humidifying
    valve
  • X4 temperature request
  • X5 humidity request
  • y1, y2, y3 change in manipulated variable for
    the cooling. heating and humidifying valve

  • Condition of mind, which expresses satisfaction
    with the thermal environment. 1
  • Criterias for thermal comfort (PMV index)
  • Air temperature
  • Radiant temperature
  • Humidity
  • Air velocity
  • Personal parameters such as clothing and
    metabolic rate
  • Criterias for thermal discomfort
  • Draught
  • High vertical temperature difference between head
    and ankles
  • Too high radiant temperature asymmetry
  • The optimum operative temperature for comfort is
    a function of metabolic rate and clothing
    insulation. 1
