THERMOACOUSTIC REFRIGERATION
INTRODUCTION
Conventional Refrigeration And Its Drawback
Thermoacoustic Refrigerator
Unpressurised System
Air as Gas Medium
Loudspeaker as Acoustic Driver
THERMOACOUSTICS
Definition
Background
Uses sound to create cooling
No moving parts inside device
Tremendous Opportunities
Saves energy
Economic potential
Good for the environment
APPLICATIONS
Heat Powered TAR
beer cooler
Coolahoop
Electrically powered TAR
spacecraft applications
Superconductivity
Cooling of computer chips
CONCLUSION
Thermoacoustic effects occur in everyday life are too small
low cost is more important than efficiency
Considerable study requires to reach acoustic devices to their full potential
