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.

Efficiency Analysis of Mechanical Redevelopment Methods with a Focus to the Problems of Joints of Inserted Materials
Mizerová, Lenka ; Tichomirov, Vladimír (referee) ; Myslín,, Jiří (referee) ; Solař,, Jaroslav (referee) ; Beneš, Petr (advisor)
Parameters that characterizes quality internal building environment come forth these days. One of the main reasons for the choice of the topic of this thesis is to ensure the quality of the internal environment and well-being during the usage of the buildings. Prevention of the excessive wall dampness is one of the basic conditions of a healthy and quality building environment. The thesis verifies reliability and compares the efficiency of the selected damp-proof materials and its joints. The first part deals with the influences that are reasons for the dampness of the buildings, earmark of an interest area, introducing of the valid legislation focused on the building redevelopment, consideration and evaluation of the building constructions in light of the dampness. The next part of the thesis sets main and partial targets and consecutive steps leading to fulfilment of the targets. Selection of the appropriate redevelopment procedures, materials and joints of the selected materials selected for the experiment realization follows. As this area is relatively large, we selected mechanical redevelopment methods reaching the walls and three most commonly used materials and its joints within the framework of the selected methods. There are three main steps set in the thesis: preparation of the methodology and experiment realization, measurement optimization and measurement within the laboratory and on the real buildings, comparison and evaluation of the measured values. Experimental part of the thesis took place between the years 2008 - 2011. Experiment realization comprises of material acquisition, building of the test samples and application of the single redevelopment measures. The next step includes measurement on the individual samples on the fixed measuring points. Measurements are evaluated through the mathematical statistical methods. Efficiency of the particular materials are compared and evaluated.

Airconditioning of the exhibition space
Dokládalová, Tereza ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
The point of this bachelor thesis is to design two air-conditioning units specifically made for assigned facility with exhibition purposes - archeopark. The units are designed in a way to accomplish operational, functional and hygienical requierements of indoor microclimate. The purpose of these units is to ventilate, cover the heat loss, elimination of heat load, humidification and dehumidification of air. Teoretical part of this thesis deals with indoor microclimate and its influence on a quality of life and also covers terms such as SBS, BRI, PMV and PPD.

Ventilation in the sports facility
Sedlařík, Jakub ; Bernard, Jiří (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with air conditioning sport object. The building is located in Znojmo. The aim was to design three air conditioning equipment for bowling, gym and sanitation. This is the air conditioning and mechanical ventilation. In the first part of the theory is mainly focused on selected objects sports facilities and sports centers microclimate. The theoretical part explain the issue halls air heating, radiant heating and air conditioning, and finally its use. After the theoretical part of the calculation follows that addresses the design of the equipment for each room.

Ventilation of the aquapark
Slabá, Jana ; Vlček, Petr (referee) ; Blasinski, Petr (advisor)
Bachelor thesis describes the design of air conditioning for aquapark. The part of the object is divided into three parts: relaxing pool, small pool (children pool) and technical facilities. The main task is to ensure the required exchange of fresh air and exhaust moisture loads from the interior. The swimming pool was further ensure coverage of heat loss in winter and heat gain in the summer. The device is designed to meet all hygienical, operational and functional requirements according to applicable legislation. In the theoretical part, the issues of water evaporation from the water surface. Calculation and design of the proposal addresses the specific design of airconditioning for equipment to operate the pools and technical facilities. Result of this work is the design documentation for these aircondition equipment.

Optimization of air conditioning of the wellness sports center
Prchalová, Nikol ; Rubina, Aleš (referee) ; Blasinski, Petr (advisor)
The diploma thesis deals with microclimate of a pool hall. This is divided into three parts. The first part describes the theoretical aspects of the environment in swimming pools in general. The second part of the diploma thesis deals with the calculation of the course of specific moisture concentration during the day in the pool hall. Different humidity concentration curves are assessed based on different electable input parameters. Subsequently, suitable setting options are evaluated in order to achieve acceptable environment in the hall in terms of humidity and optimal operating costs. The last part relates to the experimental part. This examines the measurement of evaporation under different boundary conditions and the subsequent comparison with some calculation methods for the calculation of evaporation.

Dehumidifier
Koštuřík, Adam ; Elcner, Jakub (referee) ; Hejčík, Jiří (advisor)
This bachelor thesis shall inform readers with the theory of humid air and its dehumidification at low temperatures. Here are the basic ways to dehumidify the air and then is selected a device that is suitable for low temperature conditions. Humidity problems in refrigerated areas are also described here.

Design of air conditioning in the swimmingpool hall
Mahovská, Adriana ; Rubinová, Olga (referee) ; Blasinski, Petr (advisor)
The diploma thesis is focused on the issue of ventilation of swimming halls. In the theoretical part, I assess the general issue of air quality in the indoor environment and in swimming halls, ventilation methods and elements for air conditioning in air handling units. In the project part, a complete design of air conditioning for the swimming pool buildings. For ventilation of the pool are created 2 alternative variants of dehumidification of the pool hall and their economic comparison. The experimental part is devoted to the evaporation of water from the water area when moving through water attractions.
