Summary

This article is the Spanish translation of an article presented at the 22nd IIR international Congress in Beijing, China (see the Bulletin of the IIR, reference 2007-2411). The article discusses the technical feasibility of thermoacoustic refrigerator driven by solar energy. A concept of a thermoacoustic stack (TARS) is proposed and the thermoacoustic Stirling scheme is adopted as a basic system for parametric study of a refrigeration energy transducer driven by solar energy. The relationships between pressures of input pressure, resonator pressure and output pressure and between working frequency and buffer volume are discussed, and a series of problems have been investigated by computation modelling. The main problems are the limitation of specific cold capacity in unit volume, the preferred resonance frequency and the required thermal properties of working medium in TA system. Based on the presented study an experimental prototype of the proposed system is being established.
