STUDY OF MULTI-FUNCTION SOUND REFRIGERATION SYSTEM BASED ON THERMO-ACOUSTIC EFFECT

In order to solve the serious environmental pollution problem including global warming,depletion of ozone,based on the microcosmic analysis to working process of the acoustic refrigeration and the research on the dynamic mea-suring technology about the temperature and pressure,a new multi-function sound wave refrigeration experimental system was developed,which consists of a sound wave refrigerator,a electrical controlling system,a dynamic measurement sys-tem with high accuracy,and a high-speed data collecting system.With the new experimental system,not only can we ac-complish the experimental research about dynamic correlative characteristic between every parameter of sound wave refrig-eration and the optimum experiment of refrigeration performance,but also do the experimental research about acoustic characteristic in standing wave tube,which provides an experimental basis for academic research and practicality process of acoustic refrigeration.
