A refrigerator works by compressing and expanding a fluid in order to effect a heat transfer from the medium being cooled to the atmosphere where it is allowed to dissipate. The basic system works as follows:
A fluid is compressed which causes it to heat up, this is pumped through a coil which transfers the heat of compression to the atmosphere or other fluid this cools the fluid in the system, the fluid is then expanded through an orifice where it cools even further as a result of the expansion (no heat transfer actually occurs, it's what "causes" the expansion), this then passes through another coil inside the refrigerator where it absorbs heat from the air inside the refrigerator, this heated fluid then passes back to the compressor where it is compressed again causing it to heat up again and the cycle repeats.

What is working principle?
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
WORKING principle of permanent magnet moving coil instrument?
The working principle of these instruments is same as that of the d'Arsonval type of galvanometers, the difference being that a direct reading instrument is provided with a pointer and a scale. The basic principle of this device is the interaction of magnetic field of the compass (a permanent magnet) and the field around the conductor (a simple electromagnet)
