Undercharge can cause HIGH superheat. Overcharge can cause LOW superheat.
You need some superheat when charged correctly. How much is needed is depending on outdoor air temperature and indoor wet-bulb temperature.
Excess superheat in a capillary tube system means that there is insufficient refrigerant flow through the system. This can lead to poor cooling performance and decreased efficiency. It is important to ensure the correct amount of refrigerant is flowing through the system to prevent excess superheat.

Typical superheat refers to the amount of temperature increase in a vapor refrigerant beyond its boiling point at a given pressure. In HVAC systems, a common range for superheat is between 5°F to 20°F (about 3°C to 11°C), depending on the system design and operating conditions. Proper superheat levels ensure efficient cooling and prevent liquid refrigerant from returning to the compressor, which can cause damage. Monitoring superheat is crucial for optimizing system performance and energy efficiency.
When the outdoor ambient temperature increases, the compressor superheat tends to decrease. This is because higher ambient temperatures cause the refrigerant to evaporate at a lower temperature, leading to lower superheat levels. This could potentially lead to overloading the compressor. Regular maintenance and adjustments may be needed to ensure optimal system performance.
If the TXV (Thermostatic Expansion Valve) is not properly controlling superheat, it can lead to inadequate refrigerant flow to the evaporator, resulting in poor cooling efficiency and potential compressor damage due to low refrigerant levels. Conversely, excessive superheat can cause liquid refrigerant to return to the compressor, risking compressor failure or overheating. This imbalance can also lead to increased energy consumption and reduced system performance. Proper superheat control is essential for optimal HVAC system operation and longevity.
We require to superheat the refrigerant to ensure that no liquid enters in the compressor.So in most of the cases degree of superheat is kept 2 to 3 deg c
The recommended amount of superheat for R404A typically ranges from 5 to 15 degrees Fahrenheit (about 3 to 8 degrees Celsius) for most refrigeration applications. This ensures efficient operation and helps prevent liquid refrigerant from returning to the compressor, which can cause damage. However, the exact superheat setting may vary based on the specific system design and operating conditions. Always refer to the manufacturer’s guidelines for optimal performance.
Suction superheat refers to the condition in a refrigeration or air conditioning system where the refrigerant gas is heated above its saturation temperature before it enters the compressor. This superheating is essential for preventing liquid refrigerant from entering the compressor, which could cause damage or inefficiency. It ensures that the refrigerant is fully vaporized, improving system performance and efficiency. Proper suction superheat levels help maintain optimal operation and reliability of the cooling system.
The right temperature to superheat and sub cool a substance varies greatly. Water for example takes temperatures above 212 degrees to superheat and temperatures below 32 degrees to sub cool.
Superheat depends on the type of metering device you are using in the equipment as well as the current state of the load. With a fixed orifice, the superheat will be high, about 20 to 30 degrees when the box is warm, down around 10-15 when the box is cold. With a txv, the superheat should be constant, normally between 10-15 degrees. It is best to check the superheat at the outlet of the evaporator. this will ensure that the compressor does not slug with liquid refrigerant.
