Using a heat pump
Tretera, Robin ; Křivík, Petr (referee) ; Jandová, Kristýna (advisor)
This diploma thesis provides basic information about the thermal pumps and photovoltaic systems. The heat pumps are described regarding their construction and sources of low potential heat. The description of photovoltaic systems explains the main principle of transformation the solar light to electric power and possible cooperation of this systems with the heat pumps. In practical part of the thesis there is a description of the assessed building and calculation of its thermal losses. It is followed by three designs of the thermal pump systems which are supposed to replace the original way of heating - the electric boiler. One of the designs is supported by photovoltaic system. The final part of the thesis provides the calculation of required heat sources for house and water heating, the operation expanses of all three heat pump designs, prices of electric energy and economical reliability of described solutions.
The Production using 3D Printing of Fixture for Shaping Plastic Pipes
Tretera, Robin ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This Bachelor thesis compares two options in production of shaping form for plastic pipe - handmade production versus 3D print technology (specifically DMLS method). The thesis contains detail description of the final part and shaping form with pros and cons of both production methods. Handmade production is more suitable for serial production with its lower price. In time pressure 3D printing comes up with its fast and repeatable results.
