How many grams of refrigerant should be added to the Baojun 510 air conditioning system?

Baojun 510 air conditioning system refrigerant charging amount depends on the pressure gauge reading. Refrigerant charging standards: There is a standard for refrigerant charging quantity. Air conditioners with different horsepower ratings require different amounts of refrigerant. When charging refrigerant, refer to the pressure gauge reading as different refrigerants have different pressure requirements. For example, R22 refrigerant typically has a low-pressure around 0.5MPa, while R410A refrigerant has a low-pressure around 0.8MPa. Refrigerant charging process: Recover the refrigerant, after complete evacuation, connect the manifold to the vacuum pump, evacuate the system with the vacuum pump, then select the appropriate refrigerant and charge the system.
As a long-time car modification enthusiast, I can tell you that the refrigerant charge for the Baojun 510's air conditioning system is generally around 450 grams, but this isn't just a random guess—it's essential to check the vehicle manual or diagnostic data. When recharging the refrigerant, you must use a pressure gauge to check the system's vacuum level and ensure there are no leaks in the piping before starting. Too little refrigerant results in poor cooling performance, making the car feel like a sauna, while too much can overpressurize and damage the compressor's seals. Through multiple trials, I've found that adding R134a refrigerant in small increments while monitoring the compressor's sound changes yields the best results. Additionally, seasonal factors come into play; during hot summers, slightly reducing the charge helps prevent system overload. In short, precision saves both money and hassle, so it's safer to leave it to the professionals rather than attempting it yourself.
From my experience with my Baojun, the air conditioning refrigerant charge is approximately 480 grams, as specified in the vehicle manual. When doing it yourself, first connect the refrigerant charging tool to the high and low pressure valves and vacuum for 15 minutes to remove moisture. Then carefully control the charging scale to reach the specified amount. After charging, if the air outlet temperature changes too slowly, check if the filter is clogged. Last time I overcharged, causing the evaporator to freeze—a lesson to take it slow and not rush. Regular maintenance of the air filter ensures faster cooling after replacement. Remember to check the refrigerant bottle label carefully to avoid using the wrong type. The process is simple but requires patience and attention to detail.
I believe safety is the top priority, and the refrigerant charge amount like the 470g standard for the Baojun 510 should not be exceeded arbitrarily. Too much refrigerant increases system pressure, risking pipe bursts or leaks, while too little results in poor cooling and discomfort while driving, potentially affecting other components' lifespan. I recommend using a professional pressure gauge for monitoring, operating within the safe range of 0.5-0.8MPa. Avoid DIY refills, as accidental contact with refrigerant can harm the skin—gloves and goggles are a must. Always check the pipeline for leaks before charging; repair any cracks immediately to avoid material waste. In short, entrusting a reliable technician ensures peace of mind and prevents future issues.
