Controlled dehumidification in summer season
Voleš, Jakub ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
The subject of the diploma thesis is the design and the assessment of two variants of existing HVAC system, that serves the microelectronic laboratory premises of GL Electronic company, which are situated in JIC INMEC center. The aim of the designing process is to find the optimal solution of the problem, which is concerned of excessive air humidity gains in the clean rooms. The first proposed approach is the installation of controlled dehumidification in the form of direct cooling into the yet existing device. The second considered approach is a complete deconstruction of implemented air conditioning unit and subsequent reinstalling of the brand new unit, which would meet all the requirements. Both two variants will be in the beginning outlined in a form of pre-study, selected option will be later on processed as project documentation for construction. The winning solution will be designed in the way that will satisfie the criteria of hygiene, function, and economy. The next section of the text will be dedicated to the research regarding the topic of the physical nature of air humidity, of the transportation of humidity, dehumidification of the space, also. Last but not least, the heat recovery efficiency will be measured (in the form of thermal glycol tubes). The experiment provides evidence of the system's real-time performance.

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 hospital
Minář, David ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
This bachelor thesis is focused on a proposal of air conditioning for clean spaces and their hinterlands, as well as for the hinterlands of laboratories, operating rooms, waiting rooms and X-rays. The devices are designed according to hygienic, operational and functional requirements of microclimates of buildings. The theoretical part deals with the issue of heat recovery systems. The calculation and the proposal part consist of three air conditioning devices for hot air heating and air conditioning of clean spaces and warm air ventilation of hinterlands of operating rooms, waiting rooms, X-rays, etc. The result of the thesis is detailed design of these devices.

Theoretical use of nanotechnology for filtration in HVAC systems
Bosák, Jan ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
Thesis solves problems using the nanotechnology for air filtration in HVAC systems. Main specialization work is air filtration for clean spaces with high classes of purity. For example Hospitals, sophisticated technology service, pharmacy etc. Thesis is devide for three parts. First part contains foundation infromations about theory and making fabrics by nanotechnology. Next I described laws of physics, That were using during the solving filtration´s issues. Goal for second part was making the experiments, which should show abilities and properties nanofilters during the air filtration in real environment HVAC systems. In the end measure part is compare nanofilters with common filters. There is describe nanofiltres behavior and their possibilies during the filtration as well as. In last part I expressed own opinions on air filtration by nanofibers. Opinions were making throught informations, That I found out in the process working on thesis and my experiences in HVAC field. By this facts I did compare for get a better idea. Additionally last part contains summary infomations from previously parts and own vision to development in the future. Goal work isn´t promotion and advertising sorts technologies. Ask is just summary and describe discovered knowledges, considered opinions ensue from measuring, information from the Net and people Who work in nanotechnology field.

Energy evaluation and application of heat recovery exchanger in airconditioning
Šafář, Robert ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
Master thesis deals with heat recovery in ventilation systems. Thes is an experimental measurement of the plate heat exchanger for a period of one year. Thes is Compaq es the efficiency of the heat exchanger manufacturer with achal field measurements. The first part describes the theoretical heat recovery systems, thein advantages and disadvantages, the basic formula for calculating efficiency. In the second part I come to the experimental measurements of the plate heat exchanger. There sult of this thesis is to Compaq the efficacy, showing behavior exchanger seasons and energy evaluation.

Effect of building construction on thermal load of space
Výravská, Zdeňka ; Ell, Jiří (referee) ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
This master’s thesis focuses on effect of outer building construction on thermal load of space. The effect of translucent and non-translucent construction is discussed. The project of air-conditioning system is prepared for the two alternatives of the translucent construction, including the purchase price of the airconditioning system and glazing and the savings on summer cooling. Afterwards the period of the recovery of investment is calculated. The plan of the airconditioning system is connected to my bachelor’s thesis “Airconditioning in the car showroom”, the subject of which was the plan of the airconditioning system of the car showroom.

The influence of microclimate on the inside glass objects
Dvořáková, Hana ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
This master thesis deals with the influence of glazing on the microclimate inside buildings. In particular, I focused on the shading coefficient and the various factors that affect it. The thesis also concentrates on the origin and composition of the solar radiation, the formation of thermal stress and refraction. In the next part of the thesis, I focused on designing two variants of shielding factor and its impact on the thermal load of gym, sports hall and the related necessary changes. The last part of the thesis deals with experimental measurements of incident solar radiation passing through the window into real physical model. From the measured values, we determined realistic shading coefficient and then applied it in the previous section of this thesis.

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.
