Is the refrigerant of automobile air conditioner added to the high and low pressure pipes of compressor? Why? And get in there? Why?

Add high and low pressure pipes. The low-temperature and low-pressure gaseous refrigerant is compressed by the compressor into high-pressure and high-temperature gaseous refrigerant, cooled by air wind into high-temperature liquid, throttled and depressurized by the throttle valve into low-temperature liquid mixture, and then absorbs the heat of the air in the car through the air outlet of the air conditioner, so that it becomes low-temperature gaseous refrigerant and enters the compressor, and so on.
