What are the symptoms of excessive refrigerant in car air conditioning?

[Perry]

The symptoms of excessive refrigerant in car air conditioning are: 1. The suction and discharge pressures of the air conditioning system are too high, and the operating temperature of the equipment is elevated; 2. The current value of the compressor power supply is significantly higher than normal, and prolonged operation may burn out electrical components; 3. The condenser is filled with refrigerant, reducing the heat exchange area, and high-pressure protection may occur after the car air conditioning is turned on. Car air conditioning is designed to regulate and control the temperature, humidity, and air cleanliness within the enclosed space of a vehicle. The function of the air conditioning refrigerant is to lower the temperature of the air inside the car. The refrigerant absorbs heat from the cooling medium in the evaporator and transfers the heat to the surrounding air or water in the condenser for condensation.
