Temperature request and humidity request inference TRV: error of measured and desired temperature together
with its deviation HRV: foreseen error and deviation
Integrated inferenceIf 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

. حرارتى راحتى شرايط ب“Condition of mind, which expresses satisfaction with the thermal
environment.” [1]
Criteria’s for thermal comfort (PMV index): Air temperature Radiant temperature Humidity Air velocity Personal parameters such as clothing and metabolic rate
Criteria’s 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]
