Assessment of cooling and heating factor of real heat pump
Tupcová, Tereza ; Andrys, Petr (referee) ; Rubina, Aleš (advisor)
The diploma thesis deals with the issue of replacement of non-ecological refrigerant R22 according to the requirements of relevant juristic regulations and of subsequent influence of this replacement to the efficiency of air conditioning systems. The theoretical part is focused on proceeding processes in thermodynamic cycles and during heat transfer, then determines calculation of cooling and heating factor in context with experimental measurement. The experimental measurement utilizes to the assessment of operation of heat pump after refrigerant replacement and it is source for the composion of economical evaluation of alternative solutions due to the particular choice of refrigerant replacement.

Energy evaluation of systems VRF
Gašpár, Juraj ; Hanyk, Kamil (referee) ; Rubina, Aleš (advisor)
This master thesis deals with VRF systems, which are used for extensive commercial and office buildings, or for buildings where there are multiple zones with different required parameters. The aim of the thesis is to explain the functions of the system and their evaluation and inclusion into energy classes according to the new legislation. The practical part deals with an application of the VRF system and its variants in the building of bank branch. The comparison of initials costs and resultant costs to operate the system. The experiment focuses on comparison of the measured values of VRF system and their comparison with data from the manufacturer.

Design and optimization of heat pump operation
Bergr, Josef ; Šikula, Ondřej (referee) ; Formánek, Marian (advisor)
The aim of the thesis "Design and optimization of the heat pump" is the project documentation for building permits, finding a suitable source of heat and cold. The problem is solved for a Tesco hypermarket. The device is designed to meet the health, performance and functional requirements for indoor climate. The task of this device is to transport fresh air into the interior cover heat losses in winter and coverage heat gains during the summer. The theoretical part deals with the problem of heat pumps. Special mention is about heat pump air x air. Calculation and design part is a specific proposal, two air conditioners and optimizing for winter. The experimental part deals with the processing of data on existing rooftop units.
