Energy efficient terraced house
Král, Jakub ; Bečkovská, Tereza (referee) ; Bečkovský, David (advisor)
The aim of my diploma thesis is a design of a new energy efficient terraced house in the gap site. Building has two dwelling unit of category 4+kitchenette and 6+ kitchenette. Building has a cellar, two floors and an attic. The cellar structures and horizontal structures are made of reinforced concrete. Sand-lime bricks are used for masonry. The building is covered with gabled roof with timber roof truss. In this building there are used rainwater and renewable energy in a form of electrical energy made by photovoltaic panels.

Air insulation, especially its efficiency, is often underestimated and most often it is recommended as combination of several methods by our experts. It is known that flowing air used to eliminate excessive humidity in lower construction is insignificantly promoted. Already our ancestors in ancient Rome had experience with implementation of air insulations. However, nowadays such design is connected with many doubts and it forces us to use sense, especially knowledge of construction physics. So it urges higher technical precision when designing functional ventilation system. Each building is actually a unique object, with regard to its position and used properties, that is why certain natural conditions must be accepted when designing. It is more complicated and figuratively speaking it can be written in c. 20 equations of twenty unknowns. Other problems arise in unknown coefficients to individual parameters and their effects. From another point of view it is the issue of changing air during the day, passing fronts, annual cycles and all of these in relation to internal environment of the building, materials used in the construction, land properties of rocks, and last but not least, relation to the terrain around the building. Then there are the effects of the building's altitudes etc. In total they are cycles with sine character of dampening and drying. The thesis discusses how to test the functionality of AIR insulations designed for the floor ventilation in historic buildings and follows on from the previously published articles. A flow analysis is being performed on an object of the city of Žirovnice which has been registered in the list of cultural monuments and was built as a brewery in the years 1589-1592 on the site of an older medieval building. This article brings new air-flow element. The aim of the article is to analyse in detail the air flow in a specific floor void with the aid of modern CFD programs and experimental measurements using the ALMEMO

Ventilation of a multifunctional house
Husák, Martin ; Rubina, Aleš (referee) ; Rubinová, Olga (advisor)
The bachelor's thesis deals with the design of ventilation equipment and air conditioning for a multifunctional building, which has 4 doctor's offices, a hairdresser, a driving school and 3 residential flats. The house is designed to meet all the necessary requirements regarding ventilation. Air handling units are designed to discharge degraded air to the exterior and bring fresh air back. Thermal comfort for the winter is ensured by radiators and in the summer by air conditioning. The theoretical part is focused on climatic conditions for the design of air conditioners, refrigeration systems and refrigerants.

Design of air conditioning system of a flat
Vrbický, Jiří ; Zerzaňová, Alena (referee) ; Hejčík, Jiří (advisor)
The diploma thesis is consisting of theoretic part, which deal with used ventilating systems, ways of waste heat recovery and describe basic types of air-conditioning systems. Following part attend to design of ventilating system and multi-split air-conditioning system for flat. Part of design of ventilation system is calculation of noise levels in rooms. Air-conditioner design is based on calculation of thermal stress. Annual demand of cold and heat demand are calculated using TRANSYS software. Design documentation is part of the diploma thesis.

Injection moulding
Heralt, Aleš ; Balej, Zdeněk (referee) ; Žák, Ladislav (advisor)
This Bachelor´s thesis is focused on construction forms for injection of thermoplastic matters. The technology for plastic products production is technology that participate more and more in production of all sorts of products - from technical components over kitchenware after as much as toys. Main part of this thesis is focused on description of the injection valve, ejector, annealing and ventilation system forms for injection with the main structural principles.

Air conditioning systems in educational buildings
Husák, Martin ; Uher, Pavel (referee) ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The diploma thesis deals with the design of several variants of cooling for a given building and air conditioning equipment. The building is divided into several zones. One zone was selected for which cooling variants were created. The first cooling va-riant was chosen as VRV system. The second was chosen cooling ceiling with heat pump. The last variant is fancoils with a heat pump. The results from all variants were evaluated. The theoretical part is a larger part focused on heat pumps and their use for cooling.
