air conditioning to the characteristics of the air in a particular territory of the so-called zone. A zone may be one or more rooms of the same conditioning requirements, or a whole building or facility. In addition to the dry bulb temperature, air conditioning characteristics may include:
humidity
air movement
for clean air
clean air
..
Air-conditioning applications are classified as either comfort or industrial processes, based upon their design intent. Any application whose primary function is the conditioning of air for human comfort is classified as comfort air-conditioning. Typical comfort air-conditioning applications are found in homes, schools, offices, houses of worship, hotels, retail stores, public buildings, factories, automobiles, buses, trains, planes and ships. The remaining noncomfort applications are called industrial air-conditioning. Industrial air-conditioning processes are used to:
control the moisture content of hygroscopic (moisture absorbing) materials
control the rate of chemical and biochemical reactions
limit the variations in size due to thermal expansion and contraction of precision manufactured articles
provide clean, filtered air essential for trouble-free operation of equipment and instrumentation
provide clean, filtered air essential to the production of quality products
In addition to their primary design function, industrial air-conditioning systems may also provide some comfort air-conditioning. Under these circumstances, the equipment is operated to maintain the requirements of the industrial process with the secondary function of comfort air-conditioning as an accepted outcome. It is not an essential part of the industrial system's design.
