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.

Heat Pump Supplied from Photovoltaic System
Kaděra, Jan ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
This thesis provides heat pump usage in heating mode, heating of potable water or cooling mode. The heat pump is connected with photovoltaic power plant. The main aim of this study is to create photovoltaic system connected with heat pump and present the results of an energetic and economic evaluation. The theoretical part describes principle function heat pumps, photovoltaic power plants and components. The study provides as well a description of heating systems with a heat pump used for space heating or cooling. In the practical part of this thesis was performed calculation of energy consumption in a building. Based on this data, has been selected a suitable heat pump. To reduce the energy consumption was designed a hybrid photovoltaic power plant with a battery accumulation. Utilization of electric energy from photovoltaic system was calculated. Solutions provide the option of the energy flow analysis in specific interval. Results are summarized in the energetic and economic evaluation. The proposed solution can be applied for reconstruction or construction of a new building, focused on usage of renewable resources and emissions reduction.
