MATHEMATICAL MODELING AND ADJUSTMENT OF THE PARAMETERS OF THE CONTROLLERS IN A CENTRAL AIR-CONDITIONING SYSTEM

摘要

The system that control the parameters of the air (temperature and relative humidity) in a central air conditioner is multidimensional. Even when such a system includes two independent, stably-operating controllers, the system as a whole can be unstable due to the influence of cross-effects. In this article, mathematical modeling methods are used to examine the adjustment of these controllers. Certain conditions must be created for the proper execution of production processes in factories, including the processing of artificial and synthetic fibers into yarn, filaments, and fabrics [1]. This prerequisite pertains in particular to the production environment: the composition, cleanliness, temperature, and moisture content of the air, the contents of positive and negative ions, the presence of different types of fields, etc. The process of preparing air before feeding it into the air-conditioning system of a factory building consists of a number of technological operations and is referred to as air-conditioning engineering [2]. The technology used for the heat-and-moisture treatment of air that is being conditioned depends on its initial parameters and the parameters required of (specified for) the air inside the factory building.
