Noise study of heat pump
Gregorovičová, Eva ; Hejčík, Jiří (referee) ; Jedelský, Jan (advisor)
The thesis deals with a noise study of a heat pump, which is important for the assessment of the acoustic comfort of people. The thesis describes the theory of basic terms, quantities, measuring devices and the chosen method of determining sound power. The acoustic properties and technical condition of the measured heat pump, its possible noise sources and the possibilities of reducing their emissions are also described. The total noise level of the device is determined by the intensity probe according to the scanning method according to ČSN ISO 9614-2. Based on the acoustic map and frequency spectrum, the partial noise sources of the heat pump are identified. The resulting values from the measurements are compared with the manufacturer's values. The noise situation is assessed by measuring and comparing the measured values with the hygienic limits. Furthermore, the designs of the noise protection measures are assessed, and the design of the noise protection measures for the specific case is carried out. Finally, possible noise protection measures are implemented and experimentally verified. The results confirm the need for further development of heat pumps to reduce noise emissions.

Cooperation of heat pump and photovoltaic power plant
Gregorovičová, Eva ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The bachelor's thesis assesses the heating system of a family house with a heat pump, which cooperates with photovoltaic power plant with storage heat and electricity. The theoretical part describes the main components of the system – heat pump, photovoltaic system, electricity accumulator and heat accumulator. The practical part calculates the energy requirements of the building and describes the proposed system, including the scheme. Based on the calculations and graphical representation, the system is evaluated in the balance sheet in individual months. Finally, it is economically compared with an electric boiler heating.
