Superheat was created on 2000-01-25.
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.

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, refrigerants cannot be blended.
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.
