The ancient thought that man had seven senses, (Animation; Feeling; Hearing;Seeing; Smelling; Speaking; Tasting) but it is no more than coincidence that the principal influences which affect human comfort are also seven in number:Temperature, Humidity, Radiation, Air Volume, Air movement, Air purity and Ionization.
Air conditioning is the process of treating air also as to control simultaneously its temperature, humidity, cleanliness and distribution to meet the requirements of "conditioned space". An air conditioning system may use heating, cooling, humidifying, de-humidifying and filtering units of combination of these depending upon the out side weather.
The capacity of an air conditioning system is directly proportional to the heat load in the system. The heat load consists of internal heat which is almost constant for textile mills and transmission heat which varies from time to time and season.
The maximum heat load, which occurs during summer afternoons, determines the capacity of air conditioning required for a department of the maximum heat load, roof heat load accounts 25% to 30%. Air conditioning plants are installed to maintain correct ambient condition for spinning and weaving process to work smoothly. Norms of temperature and relative humidity for textile mills are established through controlled experiments in laboratories and mills.
The author is specialized in Compact Spinning, having 2 decades of rich experience in reputable groupsand mills. He is also the writer of a book on Statistical quality control.
