RESEARCH OF EXERGY EFFICIENCY OF AIR CONDITIONING SYSTEMS FOR CLEANROOMS

In modern technologies, which are related to energy transformation, namely in the air conditioning systems, important place is occupied by objects creation and improvement of which requires the use of innovation thermodynamics. Classic apparatus of this science is often insufficient to solve new tasks; it is necessary not only to its further development, but its combination with the elements of a systematic approach and energetics. Innovation mathematical research model of the central straight flow air conditioning system for cleanroom in order to computer’s estimation its energy effective by virtue of exergetic output-input ratio depending on different factors, which have influence on its work, was described in this article. The dependence of exergetic output-input ratio for chosen air conditioning system ?е on temperature difference between the inside and the supplied air tS tin tS, depending on excess heat in the cleanroom, and moisture content dout of outdoor air was defined thanks to this model. It is shown that the chosen air conditioning system should be preferably used at higher temperature difference between the inside and the supplied air, namely, for example tS = 6,0°С (respectively outdoor air temperature tout = 42°С), that will give the opportunity to gain the highest exergetic output-input ratio е , which means to gain the most advantageous economical variant of exploitation of chosen air conditioning system.
