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.
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.
