ABSTRACT Technological systems based on thermoacoustic heat machines (TAHM) are promising for use with low temperature heat sources - waste and renewable. TAHM differs from the mechanical machines because absence of moving parts, ecological safety and high reliability. These TAHM are able to operate from external power sources. It is shown that currently there is no universal theory. These machines are less common and the main disadvantage is their low power. The aim of work is to define the elements of TAHM of low-temperature utilization systems that are currently in need of improvement. Methods for solving - analysis of modern mathematical models and experimental data for generalizing approach synthesis. Results - it is shown that the thermoacoustic theory of Rott-Swift allows you to calculate the possible acoustic power and thermal heat capacity of TA machine, but has significant limitations. Finite Time Thermodynamic model of thermo-acoustic engine takes into account the impact of external sources of thermal energy and heat exchangers design features on the TATM characteristics. This model makes it possible to optimize the parameters of TATM by power or efficiency. By combining different models several issues concerning the TA systems design can be solved, also could be designed the requirements for the design of TATM heat exchangers. Conclusions - for the design of such systems it is necessary to conduct additional studies for the development of special heat transfer surfaces and for providing the uniform temperature field.
