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.

Ice maker with direct evaporation
Loibl, Jan ; Hejčík, Jiří (referee) ; Pospíšil, Jiří (advisor)
The theoretical part of the diploma thesis deals with introduction to the issue of refrigeration systems with thermal energy storage. Possibilities of thermal energy storage with phase change are introduced. The thermodynamic principle of functioning of the particular refrigeration system type is explained here as well as its coefficient of performance and fundamental components. In addition, several examples of ice-making systems are discussed. In the practical part the design of a particular refrigeration system is calculated. The main part of the design is the cold evaporator with direct evaporation and the possibility of ice production and its usage for thermal energy storage. The calculation of the overall two-phase heat transfer is carried out.
