Design of thermal system for accurate temperature stabilization using Peltier thermoelectric modules
Motl, Jakub ; Trčka, Tomáš (referee) ; Macků, Robert (advisor)
This master’s thesis describes design procedure of a heat-regulating system to stabilize its temperature using a Peltier module. The implementation uses eight-bit microcontroller ATmega16 made by company ATMEL for the local and remote control system. The temperature sensors communicate with the microcontroller by serial SPI interface. To display user data, it has a DEM16217SYH type character LCD display with HD44780 control circuit. To collect data from the cooling areas of Peltier module, accurate ADT7320 temperature sensors are used, made by company Analog Devices. The Control of the Peltier module happens in two points of the electrode system and a bistable hysteresis software regulator is used. The first part summarizes the theory, which concerns with the design. Next part concerned with issues of the Peltier module, overview of temperature sensors, description of the microcontroller, the display unit and the used regulator. Last part describes the hardware and software implementation.

Control system for temperature stabilization
Malý, Pavel ; Běťák, Petr (referee) ; Kadlec, Jaroslav (advisor)
This bachelor´s thesis is engaged in problems, programming and proposal of Control system for temperature stabilization of any system. Main condition is using the Peltier´s component and microcontroller. Principle consists in setting of temperatures by user controls and operating of Peltier´s component thought MOSFET semiconductors. This MOSFET´s are designed to an H-bridge. We regulate power of Peltier´s component by the H-bridge. Main part of the circuit is microcontroller from ATMEL. This is called ATmega16. It’s programmed by ISP (In System Programming) property of microcontroller, which is necessary for programming of microcontrollers in applications. All measured and controlled values will be showed on the LCD display and should by supply by the 5V power source.

Design and construction laboratory exercise with Peltier cell
Mejzlík, Michal ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
The introduction of this paper describes three thermoeletrical effects and their properties. It also deals with thermoelectrical cells, which are using Seebeck´s and Peltrier´s effects. The paper decribes principles how the Peltier´s cells work, their mathematical model, construction and practical use. The paper shows what kinds, shapes and output we can meet at the market and which kinds of parameters regulate their selection. The paper suggests the possibility to measure characteristic behaviour and quantity during laboratories tasks and their evaluations. At the conclusion is adduced the suggestion of laboratory task together with theoretically made pilot protocol.

Thermostat for system testing at low temperatures
Sedláček, Jiří ; Hrdý, Radim (referee) ; Hubálek, Jaromír (advisor)
This bachelor thesis deals with proposal and construction of device that should serve for testing of developed electronic circuits at lower temperatures than the ambient temperature in laboratory. Thermoelectric Peltier’s coolers are used for cooling. The temperature regulation is provided by microcontroller control. The thesis is divided into three parts. First part includes necessary theory for realization of the device. In second part there is the detailed description of construction and function of the device. The third part summarises the measured parameters of the device. The thesis includes the technical documentation.
