The Cogeneration Units for Family House - Evaluation and Simulation
Martynek, Václav ; Baxant, Petr (referee) ; Macháček, Jan (advisor)
Master’s thesis deals with cogeneration units of low power that are used for heating of buildings and to cover the heat demand of small industrial enterprises. The introductory chapters are focusing on clarifying the principles of combined heat and power (CHP) as well as on the basic advantages and important indicators of CHP. The thesis presents a brief overview of cogeneration devices by type of primary units and also provides an overview of cogeneration units suitable for family houses that are currently available on the market. The text describes how to install and connect the cogeneration unit. The fourth chapter includes description of elemental thermal processes and possibility of heat transfer. The fifth chapter describes the thermal circuit model and calculation efficiency of a cogeneration unit. Thermal circuit consists of a cogeneration unit and a multivalent tank for hot water heating system and potable hot water system. The object of master’s thesis is to create a model of thermal circuit cogeneration units in a simulation program and a graphical user interface, that will allow a simple way to evaluate the operation of the cogeneration unit when changing the input parameters.

Heat layout of heating power plant with cogeneration unit 1600kWe
Buřil, Tomáš ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
Main target of this master´s thesis is a projection of a thermal circuit of a heating plant, which uses waste heat of a cogeneration unit with power of 1600 kWe. Electric power of a cogeneration unit is supplemented with an electric power produced from a waste heat. All heat is further used for heating in a warm water heating system. Within this thesis are executed projections of a thermal circuit of a heating plant, choice of particular devices, determination of a thermal power of devices and also determination of conditions of particular heat – transferring substances. Furthermore, design of particular devices is made, mainly for basic dimensions and heat transfer.

Computer Model of Cogeneration Unit Heat Cycle
Martynek, Václav ; Novotný, Jan (referee) ; Baxant, Petr (advisor)
Cogeneration (also combined heat and power, CHP) uses a heat produced together with electricity for coverage of heat demand. Cogeneration units of low power are recently used for purpose of heating individual buildings and coverage of heat demand of small-scale industrial enterprises. The theoretical part of this Bachelor thesis is focused on explanation of principle of cogeneration production and there are basic advantages and important indicators of cogeneration production. There is brief summary of cogeneration devices according to type of drive unit. The fourth chapter is devoted to short description of heat exchanger. The fifth chapter includes description of elemental thermal processes and possibility of heat transfer. There is a description of model of heat cycle and graphs of calculated quantities in the sixth chapter. Heat cycle includes cogeneration unit, tank for preheating hot service water, storage tank and heat exchanger, which supplies the heat to the central heating system. The object of Bachelor thesis is creating simple model of cogeneration unit heat cycle in simulation program.
