It works on principle which is reverse of a heat engine.
In refrigerators we have 2 bodies lower temperature (cold) body which is freezer and higher temperature (hot) body which is surroundings.
It takes heat from the cold reservoir and then some work is done on the refrigerator and then the amount of heat is transferred to heat reservoir.
Let Q₂ be the takes from the cold reservoir, W is the work done on the system and then releases Q₁ amount of heat to the hot reservoir.
Mathematically Q₂+ W=Q₁
