INVESTIGATIONS OF THE INNOVATION MODEL OF EXERGY EFFECTIVENESS OF AIR CONDITIONING SYSTEM FOR OPERATING CLEANROOMS

Innovation mathematical research model of the existing central straight flow air
conditioning system for operating cleanrooms with the aim of computer estimation
of its energy effectiveness by virtue exergetic output-input ratio depending
on different factors, which have influence on its work was presented in this article.
The dependence of exergetic output-input ratio η_å of the existing air conditioning
system on temperature difference between the inside and the supplied air
Δt_S = t_in - t_S was defined thanks to this model. It was noticed that at the given
temperature difference between indoor and supplied air Δt_S the change in temperature
of outdoor air practically don’t causes the change in exergetic outputinput
ratio. The chosen air conditioning system should be preferably used
at higher temperature difference between indoor and supplied air, for example
at Δt_S = 9.0°C, that will give the opportunity to gain the highest exergetic outputinput
ratio, which means to gain the most advantageous economical variant of exploitation
of the chosen air conditioning system.
