Abstract
Research in termoacoustics began with the observation of the heat transfer
between gas and solids. Using this interaction the intense sound wave
could be applied to create engines and heat pumps. The most important part
of thermoacoustic devices is a regenerator, where press of conversion of
sound energy into thermal or vice versa takes place. In a heat pump the
acoustic wave produces the temperature difference at the two ends of the
regenerator. The aim of the paper is to find the influence of the material
used for the construction of a regenerator on the properties of a
thermoacoustic heat pump. Modern technologies allow us to create new
materials with physical properties necessary to increase the temperature
gradient on the heat exchangers. The aim of this paper is to create a
regenerator which strongly improves the efficiency of the heat pump.
