The thesis analyses the possibility of designing a simple thermoacoustic cooling device which consists only of a resonator, an oscillator and a regenerator. In the introductory part of it, the basic concepts and the operating principle are described for better understanding. Theoretical calculations and numerical simulations using the DeltaEC programme, created for the analysis of thermoacoustic systems, enabled a systematic study of the effects of various key parameters on the behaviour and efficiency of the system. The results of the thesis confirm that, with an appropriate selection of parameters such as system pressure, frequency, working gas and regenerator material, it is possible to achieve significant temperature differences even with a simple system, although the energy efficiency of such systems is lower compared to classic vapour-compression heat pumps. This thesis also lays the groundwork for further research and experimental validation of the theoretical findings.
