Summary:

In the summary of invention, each important salient feature is explained as follows:

In this method of invention electro magnetic field with pulsed DC current is arranged in perpendicular direction to external magnetic field into the reaction chamber where magneto calorie effect exhibiting compounds are placed. The nano composites are arranged in a such a fashion to synthesize a new salt made up of copper oxide doped with gadalenium and dydemium rare earth elements. This compound subjected to external magnetic field pulses, exhibits magneto refrigeration effect reaching the enthaply of the system near to absolute zero i.e. -272 Centrigrage Temeperature.

4. Description

In this method an instrument is devised in such a fashion external electric field with resonating frequencies using pulsed DC current is arranged in a box consists of rare earth elements doped copper oxide salt. Copper Oxide salt in fused state is placed in a vaccuum chamber, where in controlled method using solenoid valves controlled by microprocessor releases Gadalenium fumes or vapors and Dydemium vapors into vaccuum chamber to produce the required salt. This salt is capable of exhibiting ultra low cryogenc refregeration effect when subjected to external magnetic field. The uniqueness of the system is alternating external electric and magnetic fields are used as switch to obtain maximum control in dropping the temperatures.

Background of invention

There are several methods of refregerations available like ammonia chilling freon gas chilling using compressors of various types, peltier chips like thermo electric systems. But all these type of systems have complex nature and needs electricity and higher pressures to achieve to a minimum of -140 degree centigrade. This proposed system extraordinarilty energy saving or zero electricity refregeration system which has multiple applications in industries and medical world.
