How much refrigerant should be added to Wuling Rongguang?
2 Answers
Wuling Rongguang requires 900g of refrigerant. 1. Introduction to refrigerant: Refrigerant is used in refrigeration and air conditioning systems to transfer heat energy and produce a cooling effect. Refrigerant is an intermediate substance in the refrigeration process. It first absorbs the cooling capacity of the refrigerant to lower its temperature and then cools other substances to be cooled. This intermediate substance is generally called refrigerant or coolant. 2. Principle of the air conditioning system: Through the operation of the refrigeration unit, the refrigerant entering the evaporator evaporates and absorbs heat. When cold water is introduced into the evaporator, heat exchange quickly occurs inside the evaporator. The heat is absorbed by the refrigerant, and the temperature drops to become chilled water. The chilled water then exchanges heat with the treated air through the surface cooler in the air conditioning equipment, thereby lowering the air temperature.
I remember when driving the Wuling Rongguan minivan, adding refrigerant was quite particular. The standard refrigerant amount is usually around 700 to 750 grams, depending on your vehicle's model year, with R134a refrigerant being the most common. If you add too little, the AC won’t cool effectively even after running for a while; adding too much can cause excessive pressure, damaging the compressor, which is much more expensive to repair. When doing it yourself, it’s best to use a scale for accurate measurement, check for leaks first, and avoid touching the high-pressure pipe to prevent accidents. Proper maintenance saves hassle and money—like inspecting the AC system every early summer and replacing dirty filters. Developing good habits extends your car’s lifespan.
