Cooling residential spaces by using solar energy
Staněk, Martin ; Rapta, Patrik (referee) ; Pech, Ondřej (advisor)
The bachelor thesis focuses on the design of the cooling of a residential unit in an old family house. The introductory chapter deals with the description of the air conditioning equipment and its use. The following section discusses the functions and possibilities of photovoltaic systems to reduce the economic cost of air conditioning. The third chapter discusses the parameters of the building structure. The following chapter shows an example calculation and results of the heat gains of all rooms. The penultimate chapter shows the cooling design of the dwelling unit including an additional hot water storage tank, for a higher utilization of the outdoor unit. The last chapter will show the design of a photovoltaic plant on the roof of the building to minimize the economic burden of the air conditioning operation.

Heating and cooling of the administrative building with hall
Hečko, Jakub ; Horká, Lucie (referee) ; Topič, Jan (advisor)
The bachelor thesis deals with the design of heating and cooling for an administrative building with a storage hall. The theoretical part focuses on large-area radiant heating. The computational part includes a detailed design of heating for the administrative building with a storage hall and a design for cooling the administrative building. The administrative building is heated by underfloor heating, while the storage hall is heated using hot water radiant panels. Cooling for the administrative building is designed using two-pipe cassette fan coil units. The source of heat and cold is an inverter air-to-water heat pump. Ventilation is considered forced, using air handling units. The design of hot water preparation is addressed as a priority. The project part includes drawing documentation and a technical report.

Energy Efficient Building of a Family House
Palátová, Zuzana ; Wierzbická, Helena (referee) ; Vendlová, Lucie (advisor)
This balechor’s thesis deals with a project of newly designed nearly-zero energy building in Hrachovec. It has two parts – first part presents documentation for building permission which contains drawings, fire safety design, building physics, energy performance certificate and the second part deals with design of building services which contains concept design of all systems. The building has two storeys, rectangular shape, strip foundations, ceramic mansory walls and gabled roof extending over a carport on one side. The ground storey can be entered from carport. There is a kitchen connected with a living room, a bathroom, a toilet, a utility room and a storage room. In the first storey, there are two bedrooms, master bedroom, workroom and a bathroom. Concept design of bulding services contains mechanical ventilation with heat recovery, cooling, water supply, heating, sewage system, rainwater management, electrical installation and design of photovoltaic panels. Mechanical ventilation with heat recovery is located in a utility room. Space heating is provided via air-water heat pump with floor heating. The outdoor heat pump unit is located on southeast side of the building. The indoor heat pump unit is located in a utility room. Space heating in the bathrooms is complemented with towel radiators. In the living room, there is a stove. Electricity is produced by photovoltaic panels and the building is connected to a service line. The building is connected to the sanitary sewer. Stormwater sewer is connected to a stromwater tank and blocks for soaking. The stormater will be used for watering the garden.

Experimental equipment for testing of heat pipes efeciency
Vostřel, Vít ; Lošák, Petr (referee) ; Vlach, Radek (advisor)
This bachelor thesis deals with construction of a measuring apparatus for measuring efficiency of heat pipes. The thesis first discusses heat pipes and all components of the measuring apparatus in theoretical way and than it describes construction of the real model and all needed calculations. The apparatus contains a movable arm to which the measured heat pipes are attached. The Arm is able to move form 0° to 90°. The apparatus construction procedure is also described here. The whole apparatus is controlled from the computer using Excel, macros created in Excel and Data Streamer tool.

Laboratory device with temperature control
Telecký, Jakub ; Škrabánek, Pavel (referee) ; Němec, Zdeněk (advisor)
This work deals with regulation and procedures that can be used for this. The theoretical part therefore presents the basic concepts of automation and controllers. The main part is the practical part. The purchased system consists of a regulated system, which must be set up correctly. Using system identification and known procedures, sample examples of how to best set the controller are compiled. The result is a sample laboratory task that automation students can try and gain experience with methods of setting up the controller.
