Heat exchanger design for heat pump
Tvrdý, Radek ; Toman, Filip (referee) ; Baláš, Marek (advisor)
This thesis deals with the design of a heat exchanger for a heat pump, specifically a condenser. In the introductory part, a brief research of heat pumps, refrigerants and their classification is made with a focus on the types of heat exchangers used. In the next part, the design of a shell and tube and plate condenser for a ground-to-water heat pump is made and then the two options for the heat exchanger are compared and an assessment is made as to which of the options is more suitable.

Heat exchangers, influence of cycle efficiency
Khůlová, Jitka ; Štěpánová, Lenka (referee) ; Fiedler, Jan (advisor)
The master's thesis deals with district heat exchangers in a thermal steam cycle of combined heat and power plants and with types of condensate cascades in the multilevel heating systems. Calculation of the thermal efficiency of electricity generation is provided for the investigated thermal cycle, which was modified for three different types of cascades. Besides that, a comparison of useful electric power and electricity generation through one year period of working is made. A significant part of the work is devoted to the design of district heat exchangers, including the calculation of thermal power and heat transfer area. Main dimensions are proposed for each exchanger together with a basic drawing.

Heat exchanger design for waste air heat recovery
Valentová, Helena ; Toman, Filip (referee) ; Baláš, Marek (advisor)
The master’s thesis deals with heat recovery from waste air in a multifunctional hall. The thesis contains a theoretical part that shows required parameters of an indoor environment, a composition of an air handling unit and a description of its individual parts suitable for this purpose. Subsequently a design calculation of a rotary heat exchanger and a plate heat exchanger is made. The calculation contains geometry, heat transfer and pressure drop. Then the heat exchangers are compared and a more suitable option for this application is chosen. Further the thesis includes drawing documentation of both types of heat exchangers.

Heat exchanger design
Vítek, Tomáš ; Lisý, Martin (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with the design of an additional flue gas exchanger for the use of residual energy of flue gas. Part of the work is a summary of the knowledge about heat exchangers, their principle, operation and maintenance. The next part of the thesis is the calculation draft of the heat exchanger, calculation of heat transfer and subsequent calculation of hydraulic losses for the designed exchanger. Part of the bachelor thesis is a drawing documentation of the designed exchanger too.

Replacement of existing heat exchanger
Vaculík, Štěpán ; Toman, Filip (referee) ; Baláš, Marek (advisor)
This thesis deals with the possibilities of replacing an existing inefficient heat exchanger with a new one. In the first theoretical part a research of heat exchanger types, their operational features and suitable application is carried out. In the second practical part, the control calculation of the existing bundle heat exchanger with U-tubes is performed first, followed by the thermo-hydraulic design of a new bundle heat exchanger with straight tubes and a new plate heat exchanger. In the last part of the work, a comparison and assessment of which of the alternatives is the most suitable is made.
