Where to add refrigerant to the Baojun 510 air conditioner?

Refrigerant is added to the Baojun 510 air conditioner at the low-pressure pipe of the air conditioning system. Refrigerant charging methods: There are two methods for adding refrigerant to a car's air conditioning system: high-pressure side charging or low-pressure side charging. High-pressure side charging involves adding liquid refrigerant, which is characterized by safety and speed, making it suitable for the initial charging of the refrigeration system after leak detection and vacuuming. Note that the compressor must not be turned on during this method, the engine must be off, and the refrigerant tank must be inverted. The other method, low-pressure side charging, involves adding gaseous refrigerant, which is characterized by a slower charging speed and is typically used for supplementing refrigerant. After charging is completed: After the refrigerant has been added, close the low-pressure manual valve on the manifold pressure gauge, turn off the injection valve on the refrigerant tank, stop the engine, and quickly remove the manifold pressure gauge from the compressor to avoid excessive refrigerant leakage.
