Abstract
n the modern air conditioning systems, important place are occupied by equipment and processes, the objective estimation of value of its energy perfection can be defined only on the basis of exergetic analysis. Innovation mathematical research model of the implemented central straight flow air conditioning system for operation cleanrooms 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 on parameters of indoor air, namely temperature and moisture content was defined thanks to this model. It is found, that there is no effect of moisture content on exergetic output-input ratio of the system. It is shown that the implemented air conditioning system should be preferably used at lower indoor air temperatures, namely, for example = 25 °С, and at as higher temperature difference between indoor and supplied air as it possible, for example, 9,0 °С, that will give the opportunity to gain the highest exergetic output-input ratio = 2,56, which means to gain the most advantageous economical variant of exploitation of implemented air conditioning system.
