Air handling units for ventilation of flats
Grmolcová, Eliška ; Formánek, Marian (referee) ; Rubinová, Olga (advisor)
This diploma thesis deals with small air-conditioning units for ventilation of flats and family houses. First, I studied two compact air-conditioning units, processed measured data, comparing and evaluating a unit with better technical characteristics. The second task is to process variants of design solutions for the ventilation of a family house. The first variant calculates with only one air-conditioning unit when ventilating, in the second variant two air-handling units are designed. These variants were then compared and evaluated in terms of acquisition cost and operating costs.

Design a AHU unit with respect to the heat recovery system
Otava, Jiří ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
This diploma thesis is focused on problems of heat exchangers. There are two main objectives. The first objective is based on long-term measuring of enthalpy heat exchanger, processing of measured data and comparison of result with manufacturer's results. The second objective is design of variant solutions for two types of heat exchanger of air conditioning unit of selected shop. For variant without moisture transportation was selected cross flow exchangers. Thanks to knowledge from long-term measurement, was selected enthalpy heat exchanger for variant with moisture transportation. Chosen variants were compared with emphasis on heat and moisture exchange efficiency with requirements on Ecodesign.

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.

Economic and Energy Analysis of Heat Recovery Unit in the Passive House
Hanus, Dominik ; Výskala, Miloslav (referee) ; Korytárová, Jana (advisor)
The aim of this thesis is a detailed economic evaluation of the installation and operation of passive house heat recovery units respectively in terms of energy savings resulting and the financial advantages of systems. The overall analysis is focused on the comparison of the most frequently used conventional energy management system (simple ventilation windows with the central heating based on a gas or electric boiler) with the heat recovery unit. In this work they are also considered financial resources including the “Kotlíková dotace”

Airconditioning of panel buildings
Frič, Lukáš ; Andrys, Petr (referee) ; Rubina, Aleš (advisor)
Master’s thesis is interested in air-conditioning of panel buildings. It shows problems, which happen during renovation of panel buildings. Next it shows wrong solutions, which have to solve these problems and which are used a lot today. In this thesis are designed two useful solutions, which makes internal microclimate. In experimental part is made measurement and valuation of existing condition of internal microclimate in solving building.

Hot air airconditioning of the flat house
Viktorin, Michal ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
The brachelor's dissertation is divided into three parts: theoretical, computational and design. The theoretical part is focused on heat recovery systems in air through regenerative heat exchangers. The calculation and project part deal with the design of air ventilation in flat house. The building is used for permanent housing and is divided into thirteen functional units. A technical solution is developer with regard to the statutory hygiene parameters of air and thermal comfort microclimate under applicable legislation of the Czech Republic in 2015. In addition, it will provide the ideal microclimate for housing and improve the quality of life in the building.
