Role of Air conditioning system:

    Aging of yarn yet to be drawn
    Prevention of yarn from changing
     physical properties before drawing
    Maintaining level of dyeing
    Prevention of occurrence of yarn cut
     and fluff
    Purification of room atmosphere

     background in an image
     using the Fuzzy C-Means
     algorithm (FCM)
2.   Distinguish each occupant
     by locating local
     temperature peaks in the

“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]
