Dental compressor
Sluková, Lenka ; Malášek, Jiří (oponent) ; Škopán, Miroslav (vedoucí práce)
Bachelor thesis deals with design specification draft dual cylinder oil-free compressor with membrane dryer for dental use. The first part of this thesis deals with the description of the literature search and critical functionality similar devices. The second part contains calculations of the major dimensions and design of compressor which is supplemented with drawings in. In conclusion renders the design and the total solution of the compression unit and the arrangement of the individual components.

Valves timing of compressor for CO2 refrigerant
Kamenický, Robin ; Kobský, David (oponent) ; Hejčík, Jiří (vedoucí práce)
Together with an endeavour to decrease companies’ costs and costs of their customers, significant effort to decrease an impact on the environment in the last decades was made. To do so a development is the crucial step. This paper is focused on a development of a CO2 reciprocating compressor, which is produced by Emerson Climate Technologies. The diploma work goal is to increase the compressor COP, while maintaining its durability. The document is divided into a few chapters, which address an analysis of an original compressor design, a description of a new design proposals and an evaluation of the new designs. Necessary theoretical knowledge base is also provided. In the last document part, can be read about other design possibilities and improvements. The main compressor part, for the development, was a valve plate assembly. Base on a few assumptions and original valve plate analyses, the new designs were suggested and subsequently tested as static structural problems. Natural shapes and frequencies of suction valve were determined by modal analysis. Apart from the modal and static structural analyses a CFD analysis was performed. In the last step, prototypes were tested and results were compared with the original compressor design. Software support was necessary for successful designing, thus mainly MATLAB, ANSYS WB and Microsoft Excel were used. Especially results obtained in ANSYS WB are frequently presented in this work.

Samonastavitelný výtlačný ventil
Kuruc, Marek ; Maňas, Pavel (oponent) ; Technologies,, Jan Jedlička, Emerson Climate (vedoucí práce)
Tato diplomová práce se zabývá konstrukčním návrhem samonastavitelného výtlačného ventilu pístového kompresoru firmy Emerson. Práce obsahuje rešerši současného stavu poznání, technický rozbor ventilu, výpočty podkladových parametrů. Poté je prezentován konstrukční návrh. Součástí práce je výroba prototypu a jeho provozní otestování, ze kterého jsou vyvozeny závěry pro další vývoj.
