it compresses air in the pipe's behind the fridge and places it into chamber, to keep it cold it takes air from within the fridge and re-compresses it.A refrigerator will keep food cold by converting gas into liquid, then liquid into vapour. Basic physics maintains that when two surfaces come in contact with the other, the surface with the higher temperature will cool to equal the temperature of its alternate. Coils and metal parts inside a refrigerator are loaded with cold liquid. The liquid inside generates cold air outside the coils. This happens when the heat from inside the refrigerator reduces its temperature to "match" temperatures with the cold liquid inside the coils. When you open a refrigerator door, you generally will notice a dramatic change in air temperature. Food inside is kept cold because the refrigerator is able to convert gas into liquid. That liquid passes through a series of parts that can also opt to change that liquid into vapour--this is done by compressing molecules.

They thrive in warm moist climate, where a cold moist climate is colder and not as friendly to live in. Freezing is another example of keeping food below the temperature for the bacteria to flourish.
