Water chiller for ceiling cooling system
Havlíček, Jan ; Chovancová, Michaela (referee) ; Hejčík, Jiří (advisor)
The topic of this diploma thesis is to design water chiller for ceiling cooling system. The thesis is divided into four main parts. The first part deals with the theoretical description of emitting cooling systems. The following part focuses on the theory of refrigerating systems and describes especially the thermal cycle and refrigerants which are used in cooling systems. In the third chapter refrigerating equipment are described. Compressor, heat exchangers and expansion valves belong to the main parts of refrigerating systems. The final chapter is devoted to the draft and selection of components of the refrigerating system.

DROZDOVÁ, Aneta
The adequate level of hygiene of refrigeration equipment is one of important factors that affects the maintenance of quality and safety of stored food. The aim of this bachelor thesis was to assess the efficiency of sanitation of selected refrigeration equipment in the household (n=3) and in gastronomic establishments (n=3). Microbiological analysis enabled the determination: total number of mesophilic, coliform and psychrotrophic microorganisms, and also yeasts and fungi.
