sulfuryl fluoride fumigant, also known as refrigerant, refrigerant, and refrigerant, is the medium substance used in various heat engines to complete the conversion. These substances usually use reversible phase transitions (such as gas-liquid phase transitions) to increase their power. Such as the steam in the steam engine, the refrigerant in the refrigerator, and so on. When a general steam engine is working, it releases the heat energy of the steam and converts it into mechanical energy to generate the motive power; while the refrigerant of the refrigerator is used to transfer the heat from the low temperature to the high temperature. The nature of each type of refrigerant will be different. Taking R22 refrigerant as an example, the editor will introduce:
