Study of the cooling system of a building with regard to climate change in the Czech Republic
Vašulka, Tomáš ; Charvát, Pavel (referee) ; Fišer, Jan (advisor)
The diploma thesis aims to prepare a study of the cooling system of a multifunctional building with regard to climate change predicted until the middle of the 21st century. The work includes determining the heat load of refrigerated rooms and designing measures to reduce heat gains in the summer. Diploma thesis includes design of a cooling system with fan-coil units as end appliances with the necessary hydraulic calculations. A single-stage absorption cooling unit is used as the considered cooling source, to which a free cooling heat exchanger is assigned. The design of the cooling source includes the necessary hydraulic calculations and dimensioning of the system ensuring its functional operation. Part of the diploma thesis is drawing documentation of cooling technology and connection of fan-coil units.

Cooling of Data Center
Ostrezi, Jakub ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
The aim of this work is to design data center placed into an ISO container used for transportation. Maximization of the space efficiency and minimization of the running costs are primary. This work also contains a measurement of data center electronic parts power consumption, a computational fluid dynamics model, a simulation of external thermal gains and a 3D model with basic technical drawings.

Economy building refrigeration systems
Kohút, Radovan ; Formánek,, Marian (referee) ; Rubinová, Olga (advisor)
The thesis deals with the refrigeration systems. It analyzes ways to optimize the refrigeration process and the associated energy savings. In a practical application on an industrial building where there is the need of cooling the machinery, it compares the reference system with another two optimized alternatives. The heat recovery alternative supports heating and hot water supply and the water-side free cooling alternative lowers the energy consumption during the cold period of the year. The experimental section assesses the suitability of floor cooling in relation to the stratification of air temperature along the height of the room and the effect on thermal comfort of people.
