Cooler for heat pump inverter
Trepka, Petr ; Konečný, Tomáš (referee) ; Hejčík, Jiří (advisor)
Thesis in the introductory section describes the theory of heat pumps, the principle of their functions, including components used in pumps. The thesis includes a description of the air-water heat pump indoor unit, which also includes a frequency converter. Electronic frequency converter produces waste heat that must be cooled. The most extensive part of the work therefore deals with the computational model of heat transfer in the exchanger. The output is a map of all heat pump operating points with checking cooling efficiency of the inverter. In the final part are recommended modifications of the cooler design.

Moist Air Processes in Air-Conditioning Equipment
Trepka, Petr ; Košner, Jan (referee) ; Janotková, Eva (advisor)
Bachelor thesis in the introductory part deals with the general theory of moist air, analysis of possible isobaric modifications of humid air and their representation in the h-x diagram. Bachelor thesis further contains the distribution of air-conditioning equipment, including a brief description. Thesis also includes an overview of air-conditioning systems, a description of their advantages, disadvantages and usage possibilities, focusing especially on the air system. In the final part is the dimensioning calculation of air-conditioning equipment in single-channel air system.
