What will happen to suction pressure if the refrigeration system is overcharged?

When a refrigeration system is overcharged, the excess refrigerant can lead to an increase in suction pressure. This occurs because the system becomes unable to effectively absorb or evaporate the refrigerant due to the excess volume. The increased amount of refrigerant fills the evaporator too much, leading to a condition where the refrigerant cannot fully change from liquid to vapor. As a result, the pressure in the suction line rises abnormally, which can negatively impact the system's efficiency and cooling capacity. This scenario can also lead to potential damage to the compressor and reduced overall system performance. Therefore, the correct understanding of the relationship between overcharging and suction pressure enhances the technician's ability to diagnose and address issues in refrigeration systems effectively.
