Design and verification of thermostat with peltier thermoelectric modules

In the paper we deal with design, modeling and verification of thermostat with particularly thermally insulated chamber, based on Peltier thermoelectric modules (elements). A prototype of the designed thermostat has been realized. Parameters of the regulated system were obtained experimentally. We have developed the reliable model of the complete thermostat with the PSD regulation in the Matlab environment, as well. The model helps to optimize the parameters of the regulator according to desired temperature profiles inside the chamber. Measurements show a good agreement between the model and realized prototype of the thermostat.
