Energy efficiency of heat pumps
Bártů, Marek ; Hejčík, Jiří (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the energy efficiency of heat pumps, especially efficiency of air/water system. In the this thesis is simply described the principle of the heat pump and function of each component. It shows the issues of determining the parameters of performance of the heat pump and also describes verification in according to applicable standards. The diploma thesis gives an analysis of determining the energetical efficiency and calculation of coefficient of performance, in other words, the seasonal heating coefficient of performance. Seasonal energy efficiency of selected samples of heat pumps for the heating season is designated for specific climatic conditions.

Complex evaluation of the thermo-technical properties of the building structure and heat / cold sources for family houses
Šalšová, Bára ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with overall reduction of energy use in the family house by reducing heat loss and selecting heat and cold source. In the first part are described different types of heat loss along with ways to efectively reduce each loss. Contact insulation systems are further more described, because of beeing used more often. Newer materials are also presented to readers, although their use is less common. The next chapters describe the parameters of choosed heat and cold sources. The calculating part describes process of annual power usage calculation. Further there are three designs of thermal insulation proposed and for each one the appropriate heat and cold source is selected, using heat pump with bivalent operation for all designs. Finally these options are compared in an economic and technical way and the most advantageous of them is determined.

Simultaneous utilizing of a heat pump and solar panels in a heating syste
Gongol, Jakub ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
My bachelor thesis focuses on simultaneous utilizing of a heat pump and a solar thermal collectors. I introduce principle and types of heat pumps and thermal collectors. I also introduce different sources of low-potential heat, which can be used for a heat pump. In conclusion, heat pump and solar collectors are chosen for a type house. I calculate costs needed for heating house without and with heat pump. These costs are compared and economic return is evaluated.

Design of a space heating system with heat pump in family house
Valešová, Jaroslava ; Charvát, Pavel (referee) ; Katolický, Jaroslav (advisor)
This master`s thesis deals with low-temperature heating that employs a heat pump. The introduction gives reasons for utilization of the renewable heat sources for heating. The next part focuses on a practical application of renewables on the heating of a family house. It covers a detailed description of the building and the designed heating system which includes: the calculation of thermal losses, design of the low-temperature boiler, heat pump, safety devices, heating elements, sizing and control of the system. The last part is devoted to the assessment of the system performance.
