People are gradually spending more time in indoor spaces. For this reason, the topic of ensuring a healthy indoor climate that yields positive effects on the well-being of room occupants is becoming of greater concern.
The diploma thesis describes the process of designing and creating a control system for means of regulating indoor climate in an office space. To achieve this, I designed a model of an air handling unit with elements that provide means of exchanging, heating, and cooling indoor air. To demonstrate the operation of the control system, I designed two mathematical models that describe changes in air quality and air temperature inside the office space. I also created a user interface that graphically displays the process of regulating different elements inside the air handling unit and allows for setting desired room conditions. The control program was developed using the OpenPLC software, while the graphic display of the control system was made in the ScadaBR web application.
I tested the operation of the control system and designed mathematical models by entering values that simulated different weather conditions and conditions of indoor climate. Based on the results of the test, I have concluded that the control system responds appropriately to different weather and room conditions, while the mathematical models for describing changes in air quality and temperature provide sufficient results for a simplified description of an indoor office space climate.
