Performance of the system for energy utilization from biomass
Koláček, Richard ; Máša, Vítězslav (referee) ; Pavlas, Martin (advisor)
This diploma thesis deals with the problems associated with acquisition of experimental data from technological unit for biomass combustion with nominal capacity of 1 MW, with regard to determination of thermal efficiency. In the introduction part, parameters of currently available biomass-based fuels as well as of those with large potential in the future are summarized. Further, a review in the field of biomass combustion technology is given. Biomass boilers are compared according to their technical parameters, function and benefits and drawbacks. In theoretical part methods for determination of thermal efficiency by direct method, indirect method and modified indirect method are described. Main parameters influencing resultant values of efficiency are included into the analysis. In final part an evaluation of real operational data from prototype unit combusting wooden chips is made. Recommendations for further experimental data gathering and their processing with the aim to evaluate thermal efficiency are suggested.

Reduction in energy intensity of the public object
Michek, Jan ; Chovancová, Jitka (referee) ; Vaňková, Lucie (advisor)
The thesis focuses on increasing energy efficiency of a public building. Firstly, the basic terms regarding public procurements are explained in general. A specific area of public procurements, especially contracting public procurements of small scale are studied next. The following part of the thesis is dedicated to the basic terms in the area of energy efficiency of buildings. The goal of the thesis is to evaluate all the procurement procedures related to a concrete public procurement of small scale, to evaluate the energy efficiency of the building before the realization and to reevaluate the energy efficiency including monitoring of the building after the realization.

Indoor pool ventilation
Hrabová, Kristýna ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The bachelor thesis designed ventilation for the pool hall. Hall is divided on four separate working units. The first device is designed as an air-conditioning unit for the changing room. For swimming pool were designed swimming pool air conditioning units with heat pump. Air in the hall with a water slide is adjusted using the forced ventilation unit.

Airconditioning in healthcare facilities
Růžička, Věroslav ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor thesis deals with design of air conditioning equipment serving the spaces of hospital inpatient ward and its associated facilities. Equipments designed in the computational part have the task to transport adapted fresh air to hospital premises. The system is devided into two units. Primary mechanism operates bedrooms and their sanitary facilities. Secondary mechanism operates associated facilities. Both mechanisms are designed so that hot air can ventilate in winter. To cover the heat load in summer, fancoil units are designed. Device number one is also able to manage the treatment of humidity. The theoretical part of the thesis focuses on air filters and filtration of atmospheric air.

Design of heating system for apartment building
Vtípil, Jan ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
The bachelor's thesis deals with the design of heating and water heating in a smaller apartment building in the village of Chlumětín in the Vysočina region. The aim is to design heat sources in two variants. The first variant is the classic heating with a gas boiler and hot water heating in the storage tank, which is heated by the same boiler. The second variant is more environmentally friendly heating using two air / water heat pumps and hot water heating is solved using solar collectors.

Airconditioning of the house to the medical service
Vytasil, Michal ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor's thesis deals with the design of air conditioning equipment in the house to the medical service. The solution is the basement floor with a waiting room, reception and sanitary rooms and 1.NP with surgery. Heating load of part of the basement is completely drained air handling units, in other rooms are used sub-system with fan coil units. Sanitary rooms are exhaust ventilation ceiling-suspended equipment. In the theoretical part of the thesis focuses on the bypass factor, surface temperature of the heat sink and their effect on the dehumidification.

Sports complex
Touš, Jakub ; Pobořil, Lukáš (referee) ; Petříček, Tomáš (advisor)
The main focus of this thesis is to design the expansion and modernization of a sport complex "U Jezu" for a sport club TJ Roztoky. This thesis is consisted of a study for a territorial agreement. In this study, there are indicated a formation of two playing fields with the artificial surfaces, beach volleyball court proposing two building objects as a base for the entire complex, which consists of garages, storages and a main building. A more detailed design was created for the main building. As the supporting structure of the object, the transverse wall system completed with outdoor columns supporting the cantilevered portion of the ceiling tiles, which are mainly unidirectionally reinforced concrete floor slabs. The supporting structure is based on the strip foundations. The designed building object has two-above ground floors and a ground floor, which will be created by embedding the building object into the hill side. The ground floor is designed for the relaxation and the leisure purposes. Moreover, there is also a technological equipment necessary for the operation of the facility. On the first above ground floor, there are designed locker rooms for athletes, a club room with a kitchen and an accommodation unit for a manager of the complex. The second floor is for the accommodation. There are designed rooms with lounge and office of the president of the sport club. Part of the second floor consists of a terrace. For the roofing, a flat roof with a single-classic sequence of layers is designed. In this thesis, the static is partially solved. Furthermore, the object is evaluated in the terms of lighting, acoustic and thermal requirements as well as requirements for the fire safety of buildings.

Design of a space heating system with a heat pump air-water and solid fuel source for heating the family house
Španihelová, Kateřina ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
The aim of this thesis is to design the heating system for the house, including the design and calculating the required quantity of heat for hot water. The specified heat sources are the heat pump air to water and solid fuel boiler. The task was to design the heating system to the fastest possible return on investment. The initial investment in a heat pump is high so it is necessary to design the heating system as efficiently as possible. The thesis contains a complete project of calculating heat loss of the building, the design of heating surfaces and their heat-technical calculation. There is included the design of the pipe system, the calculation of pressure loss and its regulation. The thesis also includes design of safety equipment, temperature regulation and drawings. On the basis of calculated data was processed economic assessment, which determines the return on investment to the heat pump. Compared to the gas condensing boiler the return on investment will ideally be after five years.
