The thesis is engaged in complete reconstruction of a heat system of a family house with higher heat loss, i.e. heat source, piping and radiators. As a heat source is chosen air-water heat pump. Heat system is designed with panel radiators with regard to minimum building interventions. A required power for hot water heating is calculated and selected a heat pump from suitable power range in combination with storage tank with hot water tank. The bivalent point is determined, as backup source are heating elements installed in storage tank. Drawings and circuit diagrams with safety elements are attached. In the end is calculation of estimated return.

The topic of my diploma thesis is air-water heat pumps. The diploma thesis contains three parts. In the first part I describe the theory of air-water heat pumps. In the second part I consider two variants of heating, hot water heating and pool water heating using air-water heat pumps in the family house, Révova. The third experimental part is focused on observation of operational process and calculation of heat factors of air-water heat pump while in the heating model. The calculated heating factors are then compared to the heating factors from the manufacturer's graph.

The aim of master‘s thesis is to renovate old agricultural building and design it as nzeb building. The thesis contains three parts: 1st – design of the building, 2nd – design of building services, and 3rd – assessment of the impact of different operations in building on energy consumption. The results are then evaluated for economic and environmental savings. The renovated building in village Rozkoš will be used for many purposes. It will be divided into 3 parts – a multifunctional hall, a pub, and a club room. Multifunctional hall will be used for various activities for village itself or public. In the pub will be only cold kitchen with small dishes and beverages. Club room can be used for elderly people, workout or young people. The building is low rise and structural system is combined. The vertical load-bearing walls and columns are built of bricks. Horizontal load-bearing structures are cross vaults made also of bricks. Saddle roof is made of timber roof truss. The building site contains also an outdoor car park and a garden. The project was carried out in the Revit.

This thesis theoretically in Part A deals with the solution in savings heating building and heating hot water. It examines the impact of austerity measures on the overall need for and consumption of heat energy and its economic impact and compared with each other in order to achieve maximum efficiency. Part B is their subsequent application to a given object - a residental building, various design alternatives and the resulting energy savings improvements. Experimental Part C deals with indirect measurement of the thermal conductivity of building materials.

This diploma thesis deals with pressure losses in heating systems. The diploma thesis is divided into three sections. The first part is theoretical and deals with the occurrence of pressure losses. It discusses the properties of the fluid that affect pressure losses. It also deals with hydrodynamic phenomena, flow distribution, pressure loss distribution and its calculations. The aim of the second part, which is practical, was to create a heating project for a selected object. The object is a two-floor kindergarten building located in Velké Němčice. For this project, two heating variants were created. For the first variant, radiators and heating benches were designed and for the second variant, underfloor heating was installed in the building. The goal was to use a source which will gain heat mainly from renewable sources, so the air / water heat pump was chosen as the source of heat production. The project ends with a technical report. The third part of the thesis is dedicated to an experiment which purpose was to find out how the pressure losses of the connecting pieces are reacting to the change with the change of the heating water conditions (flow, temperature). Alongside, two pipes were created which differed in the type of connecting pieces so it allowed to compare how their pressure losses differ. Both pipes were connected by radial pressing, but the fittings differed in the quality of the brass, and therefore in the construction. Also, part of the experimental section of the diploma thesis is a description of the course of radial pressing of fittings from the Herz company.

The goal of the thesis is firstly to get all the information about the initial state of solved block of flats, which is located on the street Merhautova 76/954 in Brno – Černá pole, in terms of constructions, energy consumption and initial state of heating system. In the second part of the thesis, where are discussed the possibilities of reduction of energy consumption, variant drafts of reduction of energy consumption and their financial costs and the choice of optimal variant. Third part deals with assement of solved block of flats in terms of sustainable built environment by using tool to rate buildings in terms of sustainable built environment - SBToolCZ, evaluation of possibility to use renewables. In the end are written summaries and recommendations.
