Evaporation is used for cooling in refrigerators. In refrigerator's freezing compartment, a gas, lets say freon is evaporated. Evaporation needs energy, therefore when freon evaporates it takes this energy from the surrounding, thus evaporation decrease the temperature of surrounding.

What is airconditioning?
Usually it is a machine for reducing the temperature of the air inside a house or car by using a heat-pump that works on the same principle as a refrigerator. It just makes your house a big refrigerator that you sit inside.
How does thermodynamics play a role in determining how a refrigerator works?
Thermodynamics is the branch of science that deals with heat and energy transfer. In the case of a refrigerator, thermodynamics is crucial in understanding how it works. The basic principle is that heat naturally flows from a warmer object to a cooler one. The refrigerator uses this principle to remove heat from the inside of the fridge and expel it outside, keeping the inside cool. This process is achieved through a cycle of compression, condensation, expansion, and evaporation of a refrigerant gas. By manipulating these thermodynamic processes, a refrigerator can effectively cool its interior.

How those evaporator works in a refrigerator system?
An evaporator in a refrigerator system works by absorbing heat from inside the refrigerator, causing the refrigerant inside the coils to evaporate into a gas. This process cools the interior of the refrigerator. The evaporator coils are where the evaporation of the refrigerant occurs, and the circulation of air inside the refrigerator helps to transfer the heat from the interior to the coils.
Why all electrical machines works on electromagnetic principle but not on electrostatic principle?
it works on the electromagnetic principle the conductor cuts the magnetic field which produces induces emf for the flow of current
Did Einstein create the refrigerator?
Einstein did not create the refrigerator, however he did invent a type of refrigeration device in 1926 with Leo Szilard called the Einstein refrigerator. It used no electricity and operated based on the principle of absorption refrigeration.
What is the basic working principle of Refrigerator?
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.
