Heating and cooling systems in a multifunctional building
Fuksa, Lukáš ; Horák, Petr (referee) ; Formánek, Marian (advisor)
The master´s thesis is about the design of heating and cooling of a multifunctional house. The building is functionally divided into parts of shops, administration and apartments. Thesis describes various cooling options and basic types and functions of air conditioning systems. Three variants of the system at the level for expanded building permits and their evaluation are developed. The selected variant is developed at the project level for the construction.

Air conditioning in multifunctional center
Svobodová, Leona ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
The object of this bachelor thesis is the design of air-conditioning equipment in a multifunctional centre. The devices serve a multifunctional hall and a room with over-head, the lighting and the sound. The units are designed in a way to meet all the hygienical, operational and functional requirements and to create optimal in-door microclimatic conditions for people to stay. There were used all the available budget calculations, applicable regulations and standards for this design. The air-conditioning provides a supply of fresh air and conducting of depreciated air, cov-erage of heat losses, removal of heat load and humidification of air. The theoreti-cal part deals with the system of return gaining of heat and describes advantages and disadvantages of every device enabling.

Calculation of the heat load of the train air conditioning unit
Kasal, Milan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
The subject of this diploma thesis is to apply the knowledge of thermodynamics when designing parameters of the train air conditioning unit. In the first part, the issue of air conditioning technology, basic types of cooling circuits and description of individual components are outlined. Furthermore, there is an overview of groups of refrigerants and their labelling. In the second part, a calculation of the heat load of the train unit for the limit design conditions of summer and winter operation, including the application of humid air theory are to be found. There is a basic procedure for designing the main components of compressor cooling, which is almost exclusively used in train applications, outlined. The last part contains the procedure for calculating the gains/losses in the distribution channels of the real air conditioning unit M7 and the evaluation of the results. In the appendix, there is an SW in MS Excel program, which can be indicatively used to calculate the total gains/losses of the distribution channels on any air-conditioning unit before the air enters into the train unit.

The influence of heat sources to microclimate in indoors space
Janková, Martina ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
This master thesis with the influence of heat sources to microclimate in indoor space. The aim of the thesis was to make the calculations of the dynamic behavior in indoor space and suggest ventilation systems for exhaust heat load. for found values. In the practical part of the thesis, individual systems are describing and then they are valorizing in accordance with energy intensity and thermal comfort.

Airconditioning in the clean space
Faltys, Michal ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
The bachelor´s thesis deals with the designing of air conditioning system for clean spaces of operating rooms and spaces which are necessary for assuring of operation these operating rooms. The system is proposed to meet hygienic, operational and functional requirements for indoor microclimate of clean spaces. The task of this system is the transport of fresh air to interior, the covering of the heat looses during the winter and the covering of heat gains in summer. The equipment is also designed for regulation of air humidity in the interior. The theoretical part devotes to the issue of air conditioning of clean spaces generally, calculating and project´s parts devote of the concrete concept of two air conditioning equipments for the serving of clean spaces in the specified building. The result of this work is the detailed design work of these equipments.

Variant solutions reconstruction of airconditioning systems in the laboratory
Faltys, Michal ; Andrys, Petr (referee) ; Rubina, Aleš (advisor)
The diploma thesis deals with the designing and assessment of two variants of the reconstruction of the air conditioning system for the half of 3rd floor laboratory building BioVendor – Laboratorní medicína a.s. company. The system is proposed to fulfil hygienic, operational, economic and functional requirements for indoor microclimate of laboratories. The task of this system is the transport of fresh air to interior and the covering of heat gains in summer. The equipment is also designed for the regulation of air humidity in the interior. The theoretical part deals with the application of heat penetration of solar radiation double glazed construction. Calculating and project part deals with the specific proposal of two variants of a new HVAC system-level studies of which the selected variant is developed as the project documentation. Experimental part is devoted to measuring of CO2 concentration in operationally similar laboratory. The result of this work is to evaluate the operational and economic impacts on the choice of technically feasible options and implementation documentation selected option. The benefit of the experiment is to verify sufficient air exchange to ensure the optimum concentration of carbon dioxide in laboratories.

Cooling systems for polyfunctional object.
Milatová, Adriána ; Blasinski, Petr (referee) ; Formánek, Marian (advisor)
The diploma thesis deals with the design of cooling devices of a fourteen-storey polyfunctional building with administration part and housing units. The thesis describes the physical nature of cooling, the basic types and functions of cooling systems and legislation related to cooling devices. Two types of cooling systems are selected and developed for the assigned object at the building permit design level. The work includes calculations of all elements of individual systems. The purpose of this diploma thesis is the comparison of these variants and the evaluation of suitability for use on the individual parts of the assigned building. The variant chosen is elaborated at the level of the rea-lization project, including the drawing documentation.

Air filtration
Krajčová, Kateřina ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The diploma thesis describes the design of air conditioning equipment of materni-ty hospital and experimental measurement nanofilters and their subsequent comparison with conventional air filters. The work consists of three parts. The first part describes the types of filters. Nanofilters and nanofiber materials are de-scribed in detail here. In the second part is the topic of air filtration applied to the maternity hospital. Two variants of air conditioning and cooling are designed for the 3rd floor of this building. The third experimental part deals with antibacterial effects of thr silver fiber nanofilter and its comparison with commonly used filters. It also deals with the pressure drop on the filters at different air speeds.
