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.

Air heating in the sport hall
Janková, Martina ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
The main goal of the bachelor’s thesis „name“ is designing an air conditioning device for a sport hall and its social facilities. A solution must fulfill functional, hygienic and operational requirements for the specific microclimate of sport halls. The device is designed to cover heat losses in winter as well as for cool down heat gains during summer. At the beginning a microbiological and an aerosol microclimate in an air conditioning are considered. In the next part of the thesis the required performance of the device is calculated. In the third part is the documentation of both devices is attached.

Modern technologies in thermal management of passenger vehicles with alternative drivetrain
Janíčková, Žaneta ; Kopečková, Barbora (referee) ; Fojtlín, Miloš (advisor)
This bachelor thesis is focused on the assessment of the current state of modern technologies in thermal management of passenger vehicles with alternative drivetrain. The main part of the work is based on the research into advanced systems aimed at minimizing the thermal load of the passengers and at ensuring the thermal comfort in the car cabin through various forms of the heat transfer. The study deals with reversible heat pump, photovoltaic solar panels, thermoelectric Peltier device, infrared heating, heat pipe and magnetocaloric cooling. Technologies are described from the point of view of the theoretical principle of operation, further, there are mentioned benefits and limitations of the system and the application of the technology in vehicles. Finally, a calculation of the energy demands of resistance heating as well as reversible and magnetocaloric heat pump for winter and summer operation is created for illustrative purposes. In addition to that, improvements of available systems and the potential use of prototype technologies, that can significantly contribute to reducing energy consumption while providing the required thermal comfort, are proposed at the end of the thesis.

Effective use of 3D Cad systems in the field of process engineering-III
Hájek, Zdeněk ; Dvořák, Radek (referee) ; Pavlas, Martin (advisor)
The thesis is concentrated on point of effective use of 3D CAD system SolidWorks in process engineering. This system is able to use for pipe systems besides its commonly expanded support in standard mechanical engineering. The aim is to create the library of standard parts and to create data for teaching SolidWorks in process engineering. Data are created in text form and in video form as instructing videos. The first part of the thesis contains the description of SolidWorks system, all its functions and modules. The second part contains the description of right procedures of individual parts, assemblies and drawing documentations creation. We aimed on conversion of circle-square air-conditioning pipe and flanges. The evaluation of all points of issue is mentioned in the conclusion.

Air handling units
Cakl, Dominik ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
The diploma thesis deals with the analysis of problems of unevenly stratified air flow in air handling units and subsequent optimization with respect to speed ratios, energy efficiency and legislative requirements. Methods of solving the problem are theoretical and experimental, while the theoretical part deals with air distribution by means of air-conditioning fans with a focus on their aerodynamics, pressure conditions and other requirements, which are an integral part of properly designed equipment. In the experimental part of the thesis was applied a proposal of an innovative technical approach to a specific model of air conditioning assembly, which was implemented in the laboratories of the Institute of Building Services.

Air-conditioning of pharmacy
Martincová, Lenka ; Košner, Jan (referee) ; Janotková, Eva (advisor)
Diploma thesis is focused on air-conditioning and hot air ventilation of the pharmacy. The pharmacy is a part of a supermarket building. The pharmacy has its own engine room and air-conditioning. Solution is focused with the calculation of the flow rate, thermal losses and profit of pharmacy. Power of heater, cooler and humidifier are calculated according to psychrometric evaluation. Distribution elements and distribution of a duct are designed according to the flow rate of air. Total pressure losses in the duct are calculated according to the distribution in the conclusion. Units are designed for hot air ventilation and air conditioning and the engine room. In appendix there are calculations of thermal losses and gain, output from programme of CLIMACAL, drawing documentation and material specifications.
