Design of a space heating system with a heat pump air-water and solid fuel source for heating the family house
Španihelová, Kateřina ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
The aim of this thesis is to design the heating system for the house, including the design and calculating the required quantity of heat for hot water. The specified heat sources are the heat pump air to water and solid fuel boiler. The task was to design the heating system to the fastest possible return on investment. The initial investment in a heat pump is high so it is necessary to design the heating system as efficiently as possible. The thesis contains a complete project of calculating heat loss of the building, the design of heating surfaces and their heat-technical calculation. There is included the design of the pipe system, the calculation of pressure loss and its regulation. The thesis also includes design of safety equipment, temperature regulation and drawings. On the basis of calculated data was processed economic assessment, which determines the return on investment to the heat pump. Compared to the gas condensing boiler the return on investment will ideally be after five years.

Design of warm air heating system for low-energy house
Koutník, Martin ; Krejčí, Vladimír (referee) ; Košner, Jan (advisor)
The diploma thesis deals with design of warm air heating and ventilating system for low energy house. Introduction of this thesis is focused on dividing residential buildings by their heat requirement. Then problems of residential building ventilation and possibilities of warm air heating systems including heat recovery are presented. In the next chapter summary of ventilating units with heat recovery and warm air heating units for residential low energy buildings and pasive family houses is presented. Calculation of low energy house heat losses, which is solved, is based on CSN 06 0210, CSN 73 0540 and CSN EN 12831 standards. Design and calculation of warm air heating and ventilation system and ground heat exchangers is also described. Floor heating system, fireplace insert and solar heating system are designed as supplementary systems. At the end of this thesis the control system is presented. Project documentation is enclosed in appendix.

Design of heating system for low-energy family house
Kytýrová, Zdeňka ; Hejčík, Jiří (referee) ; Košner, Jan (advisor)
This diploma thesis deals with the design of a heating system for a "low-energy" house. It is conceived as a low temperature system using a combination of radiators and underfloor heating. The design is supplemented with a calculation of heat loss, a proposal of needed components, a scheme of the system and means of regulation. The second part solves the heat source selection. A solar system with vacuum tubes is used as the primary source. The second one is an electrical water heater located in the accumulation reservoir for the hot domestic water. Necessary calculations for the design of the solar system, together with a scheme and means of regulation, are enclosed in this section.

Electronic ballast for sodium lamp
Eliáš, Jaroslav ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
The aim is to get acquainted with the way the management and regulation of sodium lamps. This knowledge is then applied to design your own gear. The introductory section describes the basic characteristics of discharge light sources. Their behavior was verified by measuring and findings were used to create diagrams, mainly the control circuit. Theoretical design is developed by individual functional parts of the inverter.

Power supply for medium pressure UV lamps
Hurdálek, Tomáš ; Zemánek, Miroslav (referee) ; Boušek, Jaroslav (advisor)
UV radiation has a very wide range of uses in industrial production and disinfection. At present, medium-pressure mercury lamps are used for the reliable generation of UV radiation. The aim of this work is to get acquainted with the principle of individual types of lamps and methods of controlling their power and to design an electronic ballast with continuous power control and, if necessary, verify the correct function of its most important parts.

Device for measurement and regulation of edible insect breeding conditions
Dvorský, Adam ; Búran, Martin (referee) ; Adámek, Martin (advisor)
This work focuses on the design and realization of a measuring and regulatory system for successful breeding of edible insects with a focus on the mealworm (Tenebrio molitor). For the correct setting of the system, the first part of the work is detected and described the general conditions of insect breeding. The description is mainly focused on the mealworm, its development and basic breeding conditions (temperature, humidity, etc.). This information is further used for the development of breeding equipment, the basic concept of which is further established at work. The device is controlled by espressif's ESP32 microcontroller. The work acquaints with its programming and the connection and programming of basic components for the proposed system. Experimental measurements verify the functionality of measurements and regulation in the breeding box. The regulation is accurate to tenths to hundredths of ° C.Last but not least, the design is compared with existing devices.

Drive of control ring PVE Merkersbach
Skoupý, Jiří ; Veselý, Jindřich (referee) ; Kašpárek, Jaroslav (advisor)
This thesis is focused on determination of forces acting to regulation ring of water power plant Markersbach (Germany). Solution of the problem is realized for two variants of servomotors – with and without servomotors acting surfaces balancing. Next topics of this thesis are strenght calculation of piston rod and bottom of the servomotors. Minimalization of the size of servomotors plungers by change of regulation kinematics has been done and minimal pressure in the pressure tank is determined. At the conclusion of this thesis received results are mentioned and its interpretation has been done. This thesis is provided for company Litostroj Power, ČKD Blansko Engineering, a.s.
