The diploma thesis deals with the design of cooling devices of a fourteen-storey polyfunctional building with administration part and housing units. The thesis describes the physical nature of cooling, the basic types and functions of cooling systems and legislation related to cooling devices. Two types of cooling systems are selected and developed for the assigned object at the building permit design level. The work includes calculations of all elements of individual systems. The purpose of this diploma thesis is the comparison of these variants and the evaluation of suitability for use on the individual parts of the assigned building. The variant chosen is elaborated at the level of the rea-lization project, including the drawing documentation.

Content of this diploma thesis is analysis of the operation of heat and cold sources and its evaluation based on data from measurement and control systém and design of a new solution for heating and cooling selected part of the object Otevřená zahrada. Building is located on the street Údolní in Brno. It is a three-storey building serving as offices of non-profit organizations and weekend activities of the organization. On the first floor there is a technical background of the building and half of it is used by four offices. On the second floor there is a seminar hall with a capacity of 50 persons. The rest of the floor is used by three meeting rooms and three offices. The third floor is used by four offices. For the heating and cooling of building, there are designed heat pumps ground-water. Air exchange in the building is provided by the air handling unit.

The diploma thesis deals with the design of the heating and cooling system, inclu-ding hot water preparation for the administrative part of the production hall. The first part of the thesis briefly discusses the history of heating and cooling of office buildings, legislative requirements and current solutions. The second part contains the design of the entire heating and cooling system with heat pump as a source of heat and cold. The final part of the thesis describes the experimental measure-ment and evaluation of the efficiency of the ice rink source.

The aim of the master thesis is to design nearly zero-energy building of the municipal office in the city of Bojkovice. In the first part an architectural and constructional solution was designed. The building has three above-ground floors. It has a flat green roof with skylights and photovoltaics. First floor includes reception, break room, archives, offices, meeting room, kitchenette, sanitary facilities and boiler room. Second floor consists of break room, archives, storerooms, offices and sanitary facilities. External load-bearing walls, internal load-bearing walls and partitions are made of ceramic blocks. Columns, girders, floor slabs and roof slabs are made of monolithic reinforced concrete. Cladding is insulated with ETICS. In the second part HVAC was designed. Heating is provided by gas condensing boiler. The building is mechanical ventilated by AC units situated in technical room in the third above-ground floor. Cooling is air-conditioned by fan-coil units designed in offices and conference hall, chillers are situated on the roof. The third part of the master thesis focused on design and comparison of various AC units. Drawings are processed in SW AutoCAD, calculations were made in Excel, the design of air-conditioning system and unit was made in SW Atrea DUPLEX 9.10, Aerocad and CLIMACAL.

The master´s thesis is about the design of heating and cooling of a multifunctional house. The building is functionally divided into parts of shops, administration and apartments. Thesis describes various cooling options and basic types and functions of air conditioning systems. Three variants of the system at the level for expanded building permits and their evaluation are developed. The selected variant is developed at the project level for the construction.
