Temperature control
Soviš, Jiří ; Glos, Jan (referee) ; Richter, Miloslav (advisor)
The thesis deals with the issue of temperature control by means of an uncontrolled source of waste heat in a closed room. The main purpose of this thesis is to get acquainted with problematics and technology used in the field of HVAC. Part of the thesis is a solution design of temperature control in which the heat loss from the compressor is used to heat the compressor room and as a supplementary heat source to the production hall to reduce costs. As part of the algorithm solution, was created a temperature model, developed in Matlab / Simulink, which was used to design a PI controller using integral quality control criterion ITAE and Nelder-Mead simplex.

Colorimeter
Škoda, Pavel ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
This thesis deals with the analysis of the color parameters for their subsequent use in the design of the device, which will be used to measure their stability in continuous production. The theoretical part defines the basic concepts and knowledge needed to understand the problems. In addition, there are described individual components and sensors suitable for color measurement. The practical part deals mainly with the descrip- tion of the construction of the colorimeter, its individual parts and the creation of the control program. At the end, there are results of the testing of the product and their overall assessment

Automation of the cultivation process in term of program control of temperature and moisture
Beneš, Vojtěch ; Papežová, Stanislava (advisor) ; Neděla, René (referee)
Theoretical part of this thesis describes different kinds of sensors used for measuring temperature and humidity of air. These sensors are categorized according to the principle on which they operate. It also describes their characteristics like range, accuracy and other aspects important for determining suitability for a glasshouse automation system.
Practical part of this work covers design of this system which can be used for auto-mated controll over temperature and humidity. It reasons about suitability of different kinds of sensors and materials. It also describes a software system capable of maintaining and changing humidity and temperature based on user input. Results of different mea-surements done during the system's operation in a variable environment are evaluated to draw conclusions about the system's ability to maintain constant temperature and humidi-ty levels inside the glasshouse.

The possibilities electricity savings of refrigeration and cooling equipment according to the distribution rate - the cold storage
Pálka, Marek ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
This bachelor´s thesis is focused on the possibilities of electricity savings of the freezing equipment, which would work only in low distribution rate and it would be disconnected from the power source in the high distribution rate. In this work, a total research in the field of refrigeration and cooling equipment, both technological circuits, as well as the principles of temperature regulation and food storage process is made. Another part of the work is focused on freezer testing standards and regulations. Much of the work is devoted to the experimental measurements, in which different types of rates on the given freezer equipment and with them associated the possibilities savings relative to other rates are measured. Another objective of the experimental measurement is to find out the temperature behaviour in the various parts of a freezing apparatus according to the switching time of the rates. There are overall experimental measurements evaluated and the possibility of electricity savings in direct reliance to the processes ongoing in the food during long term storage in the freezer in the unstable storage temperature In the conclusion of the work.

Monitoring and regulation of water reservoir
Malý, Michal ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
This work is sight on production automatic machine for temperature adjustment and highs water level in reservoir. Automatic machine watch air temperature, water temperature in reservoir and temperatures on solar panel. Further watch water mark in reservoir by the help of rustless probe. By the help of this way adventitious data governs circulatory pump and solenoid valve for suffer waters. Work includes full technical documentation including PCB.

Model Of Solar Heating in Outdoor Swimming Pool
Bartoň, Martin ; Malounek, Petr (referee) ; Chomát, Luděk (advisor)
This work deals with modeling of the technological process of heating the outdoor swimming pool. In the theoretical part are given the necessary information for resolving the simulation of heating process. Based on the theoretical background is elaborated a mathematical model of swimming pool and the technological process. This model is programmed in ANSI C language and implemented into the microcontroller ATmega8. There is also a model of the whole problem in Matlab Simulink. The result of this work is practicum model, which simulates the technological process of swimming pool heating. This model is connected to PLC B&R in which is implemented regulation and visualisation of the technological process.
