Kohlová, Vendula ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The aim of the diploma thesis is to design heating and cooling in the office building and the showroom. The theoretical part deals with large-scale heating and cooling systems. The types of these systems and their advantages and disadvantages are described here. The practical part is devoted to the design of heating and cooling in the assigned office building and the showroom. In this part, two variants of the design are considered. The first variant considers the use of a heat pump as a source of heat and cold. In the second variant of the solution, a gas condensing boiler is used as a heat source and a chiller as a cold source. The experimental part deals with measuring the properties of one ceiling panel. The main task was to determine the cooling capacity of the ceiling panel.

Heating of the shop
Straka, Štěpán ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
The Bachelor´s thesis deals with the design of the hot water rating system and the preparation of the hot water in the commercial´s building for selling of the floor covering. The theoretical part is about the underfloor heating system. The calculation part deals with the design of the heating system by the plate radiators and by the underfloor heating, design of the hot water preparation, forced ventilation, necessary technical equipments and the desing of the door screen at the storage space. Two hanging gas condensing boilers connected with the cascade connecting will be the source of the heating energy. The preparation of the hot water will be provided by the indirect heating in the hot water cylinder. The forced ventilation will be provided by the heating, ventilating and air conditioning system with the water heater and the heat recovery.

Heating of the building with a restaurant
Čechlovská, Michaela ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
The objective of this bachelor thesis is to design a heating system for a two-floor building containing a restaurant on the 1st floor, and a guest house on the 2nd floor. The building has a flat roof. The thesis is divided in three parts: theoretical, calculating, and project documentation part. The theoretical part focuses on the heat pumps: basic information, history, principle of functioning and types of pumps. The ground / water heat pump is studied in detail. The calculating part presents the heating project itself and the proposal of hot water preparation. The building is heated by the means of underfloor heating as well as a system of heaters. The heat source is designed as a ground-water heating pump with vertical ground collectors. The ventilation of the 1st floor is forced via two HVAC units, the ventilation of the 2nd floor is natural. The preparation of hot water is assured by two non-direct heating storage tanks for preheating and reheating water. Preheating by solar collectors. The project documentation part contains the technical analysis and drawing documentation.

Heating and ventilation in the "Doubrava" family house
Jirsová, Tereza ; Pech, Ondřej (referee) ; Charvát, Pavel (advisor)
The diploma thesis is focused on the design of heating and forced ventilation for the project of the family house Doubrava. In the first two chapters is briefly described the theory and there is also described the project of the family house. The next chapter deals with the design of the forced equal pressure ventilation with the heat and moisture recovery. Than the heat loss are calculated according to the norm ČSN EN 12831-1. The next part is focused on the design of heating system and the heat source for the family house Doubrava. There is described detailed design of the floor heating, including necessary calculations, and also the type of the heat pump, as the heat source and source for hot water heating, is chosen. This part also contains a selection of expansion tank and safety valve and approximate calculation of the size of the primar circuit. The last part deals with the possibilities of using renewable energy sources. At the end of the thesis, there are more detailed results of the calculations and the mechanical drawings of individual designs of the ventilation and heating system and also there are tables of the acquisition costs.

Hotel in Wallachia
Šubová, Adriana ; Krupica, Roman (referee) ; Bantová, Sylva (advisor)
The subject of this diploma thesis is the elaboration of documentation for the construction of a hotel with a restaurant in Rožnov pod Radhoštěm. The building is designed for short-term accommodation of 50 people. The building is functionally divided into a hotel part and a restaurant part. It is a detached object L-shaped building. The building is designed as a classic building with masonry system. The hotel part is designed as a two-storey with masonry system and sloping roof. The restaurant part is designed as a two-storey with basement. This part is also from masonry system and with sloping roof. The building has 22 double rooms, 1 apartment for 4 people and 1 room for people with reduced mobility, restaurant and technical facilities.

Multifunctional house in Uherské Hradiště
Kopecká, Lucie ; Šuhajdová, Eva (referee) ; Šuhajda, Karel (advisor)
The object of this master’s thesis is a newly-built mixed-use building in the town of Uherské Hradiště. It includes parking and office spaces, retail shops, and a coffee shop. The building is situated in a mildly sloping terrain near the town centre. It is a three-storey detached building with partial basement. The floor plan was created by joining several different-sized rectangles together. The mixed-use building is based on foundation pads and slabs. It is roofed with a warm flat roof and, above the first floor, with a green roof. The building consists of a cast-in-place reinforced concrete frame with columns and beams. The floor structure is composed of prestressed hollow core slabs. The external wall of the above-ground floors is made of hollow clay blocks and the basement external wall is made of permanent formwork. The wall of the lift shaft is built from reinforced concrete and the staircase is composed of precast reinforced concrete slabs. The external walls are insulated with contact thermal insulation system and in some parts there is timber cladding – ventilated façade with thermal insulation from glass wool. The thermal insulation of the basement and of the plinth is made of extruded polystyrene. The object is divided into several functional zones. On the ground floor there is a coffee shop, a copy shop, a stationery shop, and a bakery. On the first and second floors there are office spaces. In the basement there are technical facilities only. The main entrance of the object is from the northwest part of the plot. There the entrance to the car park is also located, situated to the northwest and southwest side of the plot. Bicycle stands and a place for recycling is also located there. Around the object there is a pavement from which there is wheelchair access to all of the functional zones.

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.
