Heat pumps testing methodology
Španihelová, Kateřina ; Kamenský, Petr (referee) ; Hejčík, Jiří (advisor)
This thesis deals with the methodology of heat pumps testing. The first part covers the basic principles of a heat pump from the thermomechanical point of view, the description of the heat pump basic components and low-potential heat sources. The next section describes the parameters of heat pumps according to which we can evaluate their effectiveness. The last part is targeted on the issue of testing heat pumps including a description of the test methods and description of the test heat pump air-water.

Small-scale gas heat pump
Poul, Josef ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
The diploma thesis deals with the issue of gas heat pumps. It provides a general survey of heat pumps in the first part and in the second part it aims on proposing settings of a gas heat pump for the given operating parameters. The proposed concept is applied to the specific case study of deployment in the industry with subsequent economic evaluation.

Heating historic building alternative fuels
Lampa, Jan ; Ing. Vrána (referee) ; Vališ, Ivan (advisor)
The introduction of theoretical part deals with issue of fuel. There are basic kinds of fuels, their properties and calorific values. In next part a summary of types of boilers depending on the kind of fuel is described. A process of burning in each type is discussed. Then the basic issue of heat transmission, heat losses and design of individual elements of central heating system is described. In the second part there are two studies compared to each other. In the first one an automatic pellet boiler is used as a source of energy and in the second one it’s a heat pump, type air-water. At the end both of the variants are reviewed and the better option is chosen. In the last part the better option is designed, into detailed design documentation. Important design values for using the heating system and hot water service are calculated.

Evaluation of heat pump operation data
Charvátová, Marie ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the issue of heat pumps as devices using low-potential heat of the surrounding environment for heating of buildings. In the theoretical part of the thesis there are described various types of these devices, the sources of low-potential heat and the possibilities of heat energy accumulation. The practical part of the thesis is focused on processing and evaluation of operational data of air/water heat pump used for heating of family house and assessment of importance of accumulation tank in heating system. Part of the thesis is also a proposal of optimization of heat pump control.

Design of heating system of apartment building
Lacko, Martin ; Vyhlídalová, Karolína (referee) ; Horká, Lucie (advisor)
This bachelor thesis is focused and designed on the heating of an apartment building. The theoretical part describes heat pumps, their properties and types. The calculation part is focused on the specific design of the heating system. The designed heat source is an air/water heat pump. The heating of the building is solved using board and pipe bodies. Specifically and in detail, the technical solution and implementation requirements are described in the technical report.

Heating system of a Low-energy house
Jankola, Mario ; Pech, Ondřej (referee) ; Katolický, Jaroslav (advisor)
This master’s thesis pertains to heating practices of low-energy houses using a heat pump (example 1) and low-temperature condensing boiler (example 2). The first part of the work contains calculations of suggested building’s heat efficiency and of under-floor heating. The second part of the work includes estimates of seasonal heating factors for construction with a heat pump. Based on the comparison: both of these heating systems are recommended; the capacity of the warm water container is established; and safety elements are chosen. Furthermore, a system of regulation for warm water heating is determined, and a curve of equithermal regulation for heating is calculated. Both of the recommended heating possibilities include calculations of costs of supplies and manufacturing, as well as blueprints for construction.

Proposal heat sources for home heating
Dobai, Szabolcs ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with heating and selection of appropriate heat sources for family houses. The first chapter describes heat sources used for heating by type of fuel. The second part is devoted to calculation of the energy balance and the amount of heat required for a particular object. According to the results, five possible options are selected. At the end, the economic evaluation of the selected heat sources are processed and the most suitable one is selected. The attachment provides floor plan, section, list of the elements (windows and front door) and also appearance of the house.

Utilization of thermal panels to increase the efficiency of the heat pump cooling circuit
Lainka, Pavel ; Fiedler, Jan (referee) ; Pospíšil, Jiří (advisor)
This thesis evaluates the connection of solar collectors with heat pump. The work demonstrates meaningful use of solar collector to increase cooling efficiency of the heat pump. Introduction The work introduces the reader to the issue and describes basic principles of the two main sources of energy used in the system - the heat pump and solar system. Next session is dedicated to analysis and evaluation of the data that was measured during system operation. A comparison of measured COP of the heat pump at two different modes of operation was used for the evaluation - with the help of the solar system and without using the solar system.
