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.

This thesis covers brand new detached indoor pool with one underground and one above ground floor, which is designed for a maximum capacity of 120 people, with two swimming pools, a children's swimming. The building is designed with a flat rectangular roof insulation. Envelopes are ventilated, insulated, bearing part consists of reinforced concrete. The pool hall make up the majority of the building envelope glass facade. Facilities for employees is located on the first basement floor. All technologies for cleaning pool water, air conditioning, boiler, facilities for maintenance are located on the first basement floor. Chimneys are stainless steel, placed on the outside of the building. The finish floors are ceramic tile. Pool bath is designed as a so-called white bathtub. The supporting structure of the ceiling above the pool hall beams are post-tensioned concrete.

Thesis deals with the usage of energy from recoverable resources. Theoretical part of thesis includes the description of the utilisation of heating pumps, solar radiation and biomass. The real status of the implementation is described in the second part of the thesis. Last part of the thesis contains the energy and economy valuation of real implementation.

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.

The thesis deals with energy simulation of a solar energy system in a low-energy family house with warm-air heating. The simulations performed resulted in the assessment of the energy contribution of four solar systems with different types of collectors. The profitability and return of investment for the particular system have been evaluated based on investment costs and the savings gained. The theoretical part includes an introduction to the solar energy field, solar panel systems and the passive house concept. The practical part is devoted to description of the simulated object models as used in the TRNSYS environment, the simulation results evaluation along with the assessment of the economic return on investment. The conclusion recommendations regarding a suitable type and size of the solar panel with respect to the economic criteria chosen are given.

The goal is to design a storage tank to the heat pumps air to water. The first part describes how a heat pump works and why it is advantageous to use the tank. Another section focuses on ways to accumulation of heat. Established a program that simulates the behavior of the heat pump system with storage tank, described how this program works and is designed tank size for a given heat pump. The last chapters deal with the calculation of minimum area of heat flow exchanger and the proposal inlet valve for improving the thermal stratification of the tank.

The master’s thesis contains a complete design scheme of the heating system for a family house after additional thermal insulation of some structures. In the first part, we will learn about the house and the climatic conditions. In the next section there is the calculation of the overall heat transfer coefficients for building structures and also of the heat losses of the building before and after additional insulation. In the next section there is a selection of the temperature gradient, radiators, heat proposal for an option with a single source as well as for an option with two sources. The pressure losses through each element were calculated and hydraulic balancing using the thermo-regulation valves was performed. In the conclusion the safety components were checked and the total costs of both the implementation and the drawing documentation were assessed.

The master’s thesis contains design for heat insulation of a family house for purpose of reducing the heat loss, adding a new room and complete design of heating system. First part is introducing the house, followed by calculating the heat loss for the original building. Next step proposes the heat insulation of constructions, design for the new room and recalculating the modified heat loss including comparison with the original values. Another part is dealing with the design of the heating system, providing calculations of the power requirement and the pressure loss of underfloor heating and panel radiators. After that there was the selection of the heat pump, bivalent heat source, choice of storage tank and solution for domestic water heating. In the last part the security components were checked, drawing documentation were created and attached and the calculation of return on investment was made.

The master thesis follows the bachelor's thesis entitled Water management solution of a small water Tršice reservoir. The object of the work is the completion of the water management solution at the Tršice reservoir. In the terms of the storage function of the reservoir, it will be a question of finding a possible increase of runoff for irrigation in the growing season of various crops. In the terms of the protective function, it will be a transformation of flood waves of Tršice reservoirs and below ponds.

Master’s thesis on Energy performance of domestic hot water preparation is concerned with calculating and comparing the energy performance of domestic hot water preparation in two-generation family house with an administrative part. Energy performance of domestic hot water preparation is calculated by two calculation methods and by experimental measurements, which are compared at the end of the thesis. The calculation is performed according to standard ČSN 06 0320 and set of standards ČSN EN 15316-3. Thesis is processed in accordance with valid legislative regulations.
