How many cans of refrigerant are needed when replacing the compressor on a Baojun 730?

When replacing the compressor on a Baojun 730, approximately 4 to 5 cans of refrigerant are required. High-pressure side liquid refrigerant charging: This method is suitable for charging after leak detection and vacuuming. Note that the compressor must not be turned on during this process, the engine should be off, and the refrigerant can must be inverted. Low-pressure side charging: This involves charging with gas, which is characterized by a slower filling speed and is typically used for refrigerant replenishment. Automotive refrigerant, commonly referred to as Freon, is the substance used in car air conditioning systems. It continuously circulates within the refrigeration system and achieves cooling through changes in its own state.
After replacing the compressor of the Baojun 730, it's necessary to refill the system with new refrigerant. Based on my personal experience from helping friends with similar issues at my own repair shop, the factory air conditioning system of the Baojun 730 typically requires about 550 grams of refrigerant. Since a standard refrigerant canister holds 300 grams, you'll need approximately one and a half to two canisters, depending on how thoroughly the system was evacuated during the replacement. If you have a professional shop handle the job, the technician will first vacuum the system to check for leaks, then precisely refill it to ensure optimal AC performance. When I did it myself, I used two full canisters to account for potential losses. I'd advise against DIY attempts to avoid leaks or uneven filling, which could impair cooling efficiency or even damage the new compressor. Regular AC maintenance, like checking the hoses during car washes, can reduce the need for such major repairs.
