What is the refrigerator compressor used for

　Refrigerators use evaporative cooling or vaporization to absorb heat to achieve the purpose of refrigeration. The throat of the refrigerator is filled with a refrigerant known commercially as Freon, commonly known as refrigerant. A commonly used one is difluorodichloromethane, which is a colorless, odorless and non-toxic gas with a boiling point of 29°C. Freon is pressurized by the compressor when it is in a gas state.
