Temperature Optimization of HVAC Systems using PID Control
Heating, ventilation and air conditioning (HVAC) systems in buildings aim to control the indoor climate in order to keep occupants comfortable by control the temperature and air flow. To achieve this purpose, it is necessary to have adaptable control systems that could deal with the parameters required to control the indoor climatic conditions. There are for this purpose computer models that could simulate indoor climatic processes and how to control their parameters. The success of the modeling process depends on the ability to deal with changing conditions and respond effectively as much as possible so as to maintain the necessary conditions for comfort of the occupants taking into account the cost. In this paper a thermal model for a residential room has been developed using Simulink/MATLAB trying to deal mainly with the issue of maintaining the desired indoor temperature in spite of the change in outdoor conditions.
