Renovation of the building with respect to energy demands
Balíková, Anna ; Vyhlídalová, Karolína (referee) ; Horák, Petr (advisor)
The diploma thesis deals with the solutions of the renovation of a panel apartment building with regard to energy efficiency. The theoretical part deals with heat pumps. The acquired knowledge was subsequently applied in the computational part, where the energy assessment of the current state of the apartment building and the design of two possible variants of renovation are addressed. The aim of the first variant is the renovation of the building to meet classification class C using the possible funds. The second variant is focused on the technical equipment of the building and primary energy from renewable sources, so that the apartment building reaches classification class A. Both proposed variants are assessed from both an energy and financial point of view. The project part then contains certificates of energy intensity of individual variants of the building.
Pressure losses in heating systems
Švanda, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
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.
