Monitoring of the performance of an air-to-water heat pump under real operating conditions
Elger, Jiří ; Jaroš, Michal (referee) ; Charvát, Pavel (advisor)
he Bachelor´s thesis on „Monitoring of the performance of an air-to-water heat pump under real operating conditions“ deals with the evaluation of a heat pump operation in a family house with a subsequent finding of the dependence of the heating factor and thermal performance on air temperature. The first part is dedicated to the theory of heat pumps, their categorization and explanation of the basic concepts. Next, we compare the performance characteristics and the coefficient of performance of heat pumps from different manufacturers. In the second part we describe measurements of a real heat pump which is used in a family house, the measuring instruments used, and particular measuring procedures. The third part shows the measured values plotted on charts, the measured values are analyzed, and the heat pump is checked for its suitability.

Use of waste heat of computing systems
Švehla, Michal ; Brázdil, Marian (referee) ; Chýlek, Radomír (advisor)
Using waste heat from computer systems is quiet a new area of research. The goal of this bachelor thesis is to summarize known information from this field, including descriptions of already running data centers. There are described ways of cooling which are used in data centers and mainly possibilities how to use waste heat. In the end there is shown how to evaluate suitability of using waste heat in view of data center power as well as return.

Using a heat pump
Tretera, Robin ; Křivík, Petr (referee) ; Jandová, Kristýna (advisor)
This diploma thesis provides basic information about the thermal pumps and photovoltaic systems. The heat pumps are described regarding their construction and sources of low potential heat. The description of photovoltaic systems explains the main principle of transformation the solar light to electric power and possible cooperation of this systems with the heat pumps. In practical part of the thesis there is a description of the assessed building and calculation of its thermal losses. It is followed by three designs of the thermal pump systems which are supposed to replace the original way of heating - the electric boiler. One of the designs is supported by photovoltaic system. The final part of the thesis provides the calculation of required heat sources for house and water heating, the operation expanses of all three heat pump designs, prices of electric energy and economical reliability of described solutions.

Heating of Family House by Heating Pumps
Kordiovský, Jan ; Moskalík, Jiří (referee) ; Lisý, Martin (advisor)
Bachelor’s thesis deals with the topic of heating of family house by heating pumps. Fundamental principle of their function is there explained as well as possibility of performance evaluation, different modes of operation with an additional heat source and basic distribution according to divergent criteria. In the next part were selected three types of heating pumps: air/water, ground/water and water/water. Advantages and disadvantages are evaluated for each of them. There is the question of the appropriateness of application to family houses.

Heat pump heating for a house
Loibl, Jan ; Hrnčířová, Michaela (referee) ; Nerud, Pavel (advisor)
The theoretical part of the bachelor thesis deals with introducing to the issue of heat pump systems. The functioning principle of the most widely used heat pump type is explained here as well as its coeficient of performance, its operational modes and fundamental components. In addition, possible ways of heat pump systems application in terms of obtaining lowpotential heat are introduced. In the practical part the calculation of thermal loss of selected family house is discussed together with the calculation of heat requirements for heating and domestic hot water. The following part focuses on the selection of the most appropriate type of heat pump systems for covering heat demands of the selected house. The final part poses economical assesment of the designed heat pump system including the calculation of investment recovery.
