Heat exchangers
Kuráňová, Helena ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The master thesis deals with the issue of heat recovery and efficiency of exchangers. The experimental part is dedicated to the measurment of efficiency of a plastic model of heat exchanger with atypical construction compared to a standard plate heat exchanger. For production of the heat exchangers 3D printer was used so the thesis uses the possibilities that 3D printing is offering nowadays.

Airconditioning in a sport center
Šafář, Robert ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
Bachelor work is focused on designing an air conditioning system for the gym so as to meet functional, hygienic and operational requirements for the microclimate of sports building. The main tasks of the device are covering heat losses of area of the gym in the winter and transportation of fresh air into the room. The system is also designed to cover the summer heat gains. The first theoretical part deals methods of heat recovery for air conditioning needs, and the second part contains two designs of ventilation of changing rooms and air conditioning system for gyms. The result of this work is detailed design work for two air conditioning equipments for specified object.

Design of air conditioning in the family house
Němcová, Aneta ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The subject of this dissertation is the design of an air conditioning system for a family house. The design contains the actual state, in which a central unit with variable air volume regulators and air supply adjustment is designed. The first version of optimisation offers a simple central ventilation, and in the second version a decentral ventilation for the object. These options were compared based on their purchasing price and additionally from the interior comfort feel point of view. In the next part a long-term measurement of an energy recovery ventilation was performer, and data was processed to evaluate and compare the efficiency with efficiency promised by producer.

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.

Parametric Study of Air Heat Exchanger
Podola, David ; Volavý, Jaroslav (referee) ; Fišer, Jan (advisor)
This diploma thesis deals with the impact of changes in operating and geometrical parameters of regenerative heat exchanger on the efficiency of decentralized ventilation units with heat recovery. Decentralized ventilation unit can be used for ventilation of family houses or smaller administration buildings. Output of this work is to determine the efficiency of a particular produced model of decentralized ventilation unit and overview of the possibilities increased efficiency of heat recovery of this units.

Air condition of cultural center
Bělehrádek, Lukáš ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The aim of the bachelor thesis is to design an air condition of cultural center. The theoretical part describes processes of heat recovery in general, followed by description of various heat recovery ventilation systems in airconditioning. Design of an air condition for a multipurpose hall with an entrance hall and a pub is dealt with in the practical part of the thesis. The design consists of two air-conditioning units for cooling, and for warm air heating. The last part of the thesis consists of design documents for the air condition of cultural center.

HVAC systems of hospital - Ecodesign 2018
Dokládalová, Tereza ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
The subject of this diploma thesis is a review of legislation about ecodesign, the design of air conditioning systems for hospital departments and analysis of energy consumption of air conditioning systems designed before and after ecodesign 2018. The thesis is divided into three parts. The theoretical part deals with research of ecodesign legislation (especially EU Commission Regulation No. 1253/2014) and air conditioning in health care facilities. In the second part design of two air-conditioning systems serving the hospital's traumatology department was realized at the level of documentation for building permission. The third part contains calculations and assessments of expected consumption of electric and thermal energy, comparison of units before and after ecodesign and evaluation of annual operating costs.
