under charge
To calculate superheat, subtract the actual temperature of the refrigerant from its saturation temperature at the current pressure. This will give you the superheat value, indicating how much the refrigerant has increased in temperature above its saturation point. Superheat is important in ensuring optimal functioning of air conditioning and refrigeration systems.
As superheat increases, the discharge line temperature is likely to also increase. This is because superheat represents the temperature rise of the refrigerant vapor above its saturation temperature, which results in higher temperatures in the system. The discharge line temperature tends to follow the trend of superheat in the system.
intermolecular forces are hard to overcome...apex
Boiling point is a property not a force; but a high boiling point indicate a strong intermolecular force.
They show how steep a landform is. A contour line also is a function of two variables in a curve which has a constant value.
a starved evaporator.
ok this is the answer only if u tell me what evidence is there that the ziggurat existed

Overcharged system
discharge pressure is high, suction pressure is high superheat is low and subcooling is high.
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.
Excessive superheat, caused by a low refrigerant charge.

Yes, checking superheat on a thermostatic expansion valve (TXV) is essential for ensuring proper system operation. Superheat helps determine if the TXV is functioning correctly by measuring the temperature increase of the refrigerant vapor above its saturation temperature after it leaves the evaporator. Proper superheat levels indicate efficient heat exchange and help prevent compressor damage due to liquid refrigerant flow. Adjustments may be necessary if superheat is outside the manufacturer's recommended range.
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.
In a typical refrigeration or HVAC system, the superheat at the end of the evaporator should generally be between 5 to 15 degrees Fahrenheit (3 to 8 degrees Celsius). This range ensures that the refrigerant is fully vaporized before it enters the compressor, preventing liquid carryover that could damage the compressor. Proper superheat levels also indicate efficient system operation and help maintain optimal cooling performance.
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
