The issue of energy-efficient home heating
Kollár, Ľubomír ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
Low-energy houses are becoming more common and requested. The Bachelor's thesis focuses on heating and ventilation of low-energy houses. The beginning chapters describe and explain basic principles of these buildings and basics of air-handling and heating systems. The main part of the work overviews contemporary heating and ventilation systems while pointing out their advantages and disadvantages. The work includes a design of heating and ventilation of low-energy house.

Design of modular tubular heat exchanger
Marx, Sven ; Turek, Vojtěch (referee) ; Jegla, Zdeněk (advisor)
Hlavním cílem této práce je seznámit se s požadavky specifické procesní aplikace a návrhem výměníku tepla s křížovým tokem pracovních látek a zhodnotit návrh předmětného výměníku pomocí simulačního softwaru. Nejprve jsou v práci prozkoumány provozní podmínky rekuperace odpadního tepla a obecné možnosti návrhu a jsou uvedeny základní rovnice pro tepelný a hydraulický výpočet. Hlavní část práce se zaměřuje na modulární trubkový výměník tepla s křížovým tokem pracovních látek navržený pro experimentální výzkum rekuperace tepla a zanášení ze znečištěných spalin produkovaných spalováním alternativních paliv na VUT v Brně (VUT) na Ústavu procesního inženýrství (UPI). Nejprve je stručně představena situace v testovací laboratoři. Poté je popsán postup návrhu předmětného tepelného výměníku pomocí softwaru HTRI a výsledky jsou shrnuty a porovnány s cílovými požadavky. Následně je analyzována distribuce toku vody v trubkovém prostoru uvnitř jednoho ze čtyř identických modulů výměníku tepla užitím softwaru CDF pomocí tří různých simulačních přístupů. Jsou popsány dva přístupy využívající model turbulence k--SST a jeden přístup využívající model turbulence k--Realizable turbulence. Nakonec jsou diskutovány rozdíly mezi přístupy a výsledky simulací distribuce toku.

Application and evaluation of energy enthalpy heat exchanger
Jetelina, Michal ; Horák, Petr (referee) ; Uher, Pavel (advisor)
This master thesis is solving measuring the efficiency heat recovery and application unit, which includes heat recovery into selected building. In the first part of the thesis are analy-zed the different types of heat recovery system, their behavior and suitability of use in HVAC systems. The second part includes the actual experiment, when were measured parameters of air, which passed through the unit and then were analyzed the results. In the last part, third, was measured unit applied to the selected house and was compared to operation of the unit in case of use by the producer given unit parameters and measured parameters.

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.

Ventilation of a multifunctional house
Husák, Martin ; Rubina, Aleš (referee) ; Rubinová, Olga (advisor)
The bachelor's thesis deals with the design of ventilation equipment and air conditioning for a multifunctional building, which has 4 doctor's offices, a hairdresser, a driving school and 3 residential flats. The house is designed to meet all the necessary requirements regarding ventilation. Air handling units are designed to discharge degraded air to the exterior and bring fresh air back. Thermal comfort for the winter is ensured by radiators and in the summer by air conditioning. The theoretical part is focused on climatic conditions for the design of air conditioners, refrigeration systems and refrigerants.

Air conditioning of the cinema
Czempka, David ; Rubinová, Olga (referee) ; Blasinski, Petr (advisor)
The aim of this bachelor thesis was to design air-conditioning systems in the selected cinema equipped with a spacious foyer with bar, cinema hall with technical facilities, recording studio and secondary spaces. Systems are designed to meet hygienic, operational and safety requirements and to create an optimal indoor microclimate for people. The air-conditioning systems provide distribution of fresh air and extract of exhaust air, covering the heat loss in winter and heat gains in summer, and in selected spaces also humidification in the winter season. In the theoretical part of the thesis, I focused on the basic acoustic quantities and spatial acoustics.
