Application of refrigerant cooling for air conditioning of buildings
Vlček, Petr ; Rubina, Aleš (advisor)
Diploma thesis deals with the problem of refrigerant cooling needs for air conditioning systems of buildings. Summary focuses on the theoretical basics and the physical nature of refrigeration and air conditioning technology. The consequences of split unite on microclimate in the room was experimentally tested and simultaneously investigated happenings associated to its activity. The aim is to unify the theoretical and experimentally obtained facts and apply them in the designing of air conditioning units. Design of air conditioning systems builds on my bachelor thesis, "Hot-air heating of gym", which subject was the ventilation system of gym.

Heat pumps used in airconditioning
Géryk, Ondřej ; Rubina, Aleš (advisor)
This thesis deals with issues of heat pumps for air conditioning purposes. Mainly addresses itself with physical principles of heat pumps and with division of heat pumps according to natural resources, from which they draw heat energy. The next part of this thesis dedicates itself to experimental measurement of air conditioning unit, which in winter time operates on the principle of heat pump. The last part of this thesis is focused on design of two options of employment of heat pumps as sources of heat and coldness for a central air handling unit, which regulates incoming air for a dining room in a retirement home in Brno.

Energy evaluation of apartment building's attic space
Sluka, Marek ; Dvořáková, Hana (referee) ; Rubina, Aleš (advisor)
The bachelor thesis deals with energy evaluation of apartment building’s attic space at Křenová Street in Brno. The results will be compared with energy consumption values, measured during the last years. The main task is to suggest a more energy efficient solution to the evaluated space. Refrigerants for compression cooling system will be described in the theoretical part of the thesis and, as a result, a refrigerant for the optimized solution will be specified.

Pile Foundations - Energy Piles
Hoza, Martin ; Leiter, Augustin (referee) ; Glisníková, Věra (advisor)
At a time when ecology and renewable energy sources come to the fore, the use of geothermal energy appears to be one of the suitable alternatives. The aim of this paper is to explain the function of ground source heat pumps, to mention factors affecting the efficiency of the system and discuss the technology of energy piles realization. This paper also focuses at risks associated with the soil temperature influencing and shows examples of realization.

Cooling systems and their management in office settings
Kotásek, Petr ; Šikula, Ondřej (referee) ; Formánek, Marian (advisor)
The bachelor thesis deals with the cooling systems of office spaces. The theoretical part focuses on the principle of operation of commonly used cooling systems and the possibility of cold production. This work describes the advantages and disadvantages of each system. The result of the calculation is design of optimal cooling system for the office building, which secures the removing of the heat load in the summer.
