Využití mikrokontroléru k řízení tepelné soustavy

Abstract

This work describes the principle of thermoelectric phenomena, their use by thermoelectric cells and the construction, properties, and possibilities of using thermoelectric cells in practice. Another goal is to design and construct a laboratory model of a heating system, in which the Peltier cell acts as an actuator and to describe the function of this proposed laboratory model. Subsequently, a microcontroller suitable for control (and regulation) of the heating system is selected and described, a PCB is designed and manufactured to adapt the signal levels of the connected sensors and actuators, and an algorithm for regulating the temperature several places of the heating system is implemented. At the end of the work, the achieved results are evaluated.
