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.

No r404a is not compatible with r409a, r134a and 404a use the same lubricates and are compatible but r409a use a different lub making them incompatible
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 systems means that there is ______ charge
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
No. There'll still be residual traces of R22, even if the cylinder is empty, and it won't blend with the R404A. Furthermore, the R22 cylinder will be labeled as such, and it's actually a crime to have such cylinders improperly labeled.
R134A, R22A, R404A, R410A and many more
