How much refrigerant is generally added to a Nissan Sunny?

[Bryce]

Nissan Sunny refrigerant is generally filled between 600-800g. The amount of refrigerant should be determined based on a professional air conditioning pressure gauge. Below are the methods to determine whether refrigerant needs to be added: Air conditioning working state: After the air conditioner has been running normally for a while, the air blowing on you should feel very cool and quickly reach the set temperature. The outdoor compressor should work intermittently, similar to a refrigerator. If this is the case, the air conditioner is functioning normally; otherwise, refrigerant may be needed. Temperature difference too low: Use a thermometer to measure the temperature difference between the air inlet and outlet of the indoor unit. A difference of more than 8 degrees Celsius is normal. The greater the difference, the better the air conditioner is working. A good result can reach around 15 degrees Celsius. If the difference is below 8 degrees Celsius, refrigerant may need to be added. Condensation on the copper pipes of the evaporator: After running for more than ten minutes, open the panel of the indoor unit. You should see the copper pipes of the evaporator, which are covered with aluminum fins for heat exchange, evenly covered with condensation. This is normal. The amount will vary depending on the air humidity—more when humidity is high and less when it is low. If only half of the pipes have condensation, it may indicate a lack of refrigerant.
