Inside of the can, there is a chemical which can be used as a refrigerant. It's a chemical with a low vapor pressure. When you press the button on top of the can, you open a valve and release some of the pressure from the can.
Carburetor ice is caused by the change in pressure as air passes through the venturi. Fuel atomized in the throat of the venturi evaporates. This uses heat from the metal of the carburetor and air. This air/fuel at lower pressure cools and takes even more heat away from the metal of the carburetor. At some point any moisture in the air will freeze on the metal of the carburetor.
