Why does a sedan's air conditioning cool but the car interior doesn't feel cold?

A sedan's air conditioning cools but the car interior doesn't feel cold due to insufficient refrigerant caused by low refrigerant levels. Here is relevant information about vehicle air conditioning: 1. Refrigerant loss: Generally, car air conditioning systems normally lose 10% to 15% of refrigerant annually due to different sealing methods of automotive air conditioning compressors. 2. Refrigerant refill quantity: Add 10%-15% annually. When the pressure gauge shows normal readings, immediately turn the piercing device's needle clockwise to its lowest position and tighten it, then move the low-pressure port connector of the air conditioning system. If one bottle isn't enough, add a second bottle of refrigerant using the same method until the external temperature matches the system pressure.
