MODELING, SIMULATION AND CONTROL OF WINTER REGIME OF AN AIR CONDITIONING SYSTEM IN A CLASSROOM

Abstract

This paper presents analysis of control algorithm in HVAC, with an aim to minimize energy needs and to improve dynamic characteristics of plant. For this study a classroom is used, which is located at Automatic Control Department at Faculty of Mechanical Engineering in Belgrade. A winter regime of an air conditioning is considered. Mathematical model of the classroom is presented and with control system. Considered control algorithm is cascade P-PI. Model were tested and simulated in MatLab Simulink environment for winter regime of the air conditioning system.
