Environmental priorities are forcing chloro-fluorocarbons out of market place thereby creating a new demand for cooling

technologies. This paper presents an outcome of researches done to design, construct and evaluate a CFC free refrigeration

system. A prototype Thermo acoustic cooling system utilizing high amplitude sound waves in an inert gas is discussed.



Thermo Acoustic Engines

A thermo acoustic engine converts some heat from a high Temperature heat source into acoustic power rejecting waste heat

to a low temperature ....etc

Infrared thermometers measure temperature using blackbody radiation (generally infrared) emitted from objects,Infrared thermometers is a non-contact thermometers to measure temperature from a distance.The basic design consists of a lens to focus the infrared energy on to a detector, which converts the IR energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation,Infrared thermometers (IR) can be use in some critical conditions like Detecting clouds for remote telescope ....etc
