What Happens When Too Much Refrigerant is Added to a Car's Air Conditioning System?

Adding too much refrigerant to a car's air conditioning system can increase the pressure within the system. When the air conditioning control system detects excessively high pressure, it will frequently cut off the compressor's operation, leading to poor cooling performance. Additionally, the consistently high pressure in the air conditioning pipes can cause damage to the system's components. Below is a detailed introduction regarding the addition of refrigerant to the air conditioning system: Function of Refrigerant: The role of adding refrigerant to the air conditioning system is to enable cooling. Only by serving as a refrigerant within the air conditioning system can it effectively regulate the indoor temperature. Cooling Principle: The air conditioning compressor primarily draws gaseous Freon from the evaporator into the main unit. After undergoing compression, it is converted into a high-temperature, high-pressure gas, which is then sent to the condenser via an expansion valve. After dissipating heat, it becomes a low-temperature, high-pressure liquid. Although the air conditioner itself blows out hot air, after undergoing low-temperature and high-pressure processes, the Freon passes through the capillary tube and flows into the evaporator for throttling. The space expands, and the pressure decreases, converting it into cold air, thus blowing out cooled air. Frequency of Adding Refrigerant: During the operation and use of the air conditioning system, if the Freon becomes insufficient or leaks, even if all other components of the air conditioner are functioning normally, the system will not be able to provide cooling or heating. However, as long as the air conditioning system is sufficiently sealed, no matter how long it has been in use, there is no need to add Freon, and the cooling and heating effects can remain excellent. If it is necessary to add Freon to the air conditioning system, it should only be done when there is a shortage or leakage of Freon.
