Heating of the guesthouse
 Diatel, Jakub ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The theoretical part of this thesis is based on ideal design of solar systems and determine physical properties of antifreezing mix based on glycol in different concentration by Swiss mathematical model. In practical part is solved heating of the guesthouse by pellets. Heating of the hot domestic water was designed by solar collectors. Forced ventilation was designed with heat recovery.

The dynamic characteristics of check valve
 Pavlík, Václav ; Dokoupil, Pavel (referee) ; Habán, Vladimír (advisor)
This master´s thesis provides an overview of all designs of check valves, their usage and typical features. Main purpose of this work is to clear up the phenomenon of check valve slam and the other problems that occur during transients. The check valve slam was measured at the test rig in the hydraulic laboratory. For unsteady flow evaluation after pump shut down was used Gibson method. The dynamic characteristic was possible to create by results from this method. It was achieved without impact of the speed of sound in the fluid. This work also contains 2D transient CFD calculations, which was used for evaluation of the hydrodynamic torque acting on the hinge pin. This approach provides an option to calculate wide range of cases at the expense of not entirely exact geometry. The main contribution of the theoretical study at the beginning of this thesis is its entireness. It might give an important clue when right valve is selecting. For good choice of valve might be helpful to use dynamic characteristics in this thesis presented. Mentioned characteristics were created by new way and its background is in measurements and simplified CFD calculations.
