Formula for superheat and subcooling
With fixed metering, superheat will vary widely with load and head pressure. With a TXV, superheat will be much more consistent over a variation in load and head pressure, provided the system is charged properly and airflow is good. Subcooling tends to be more consistent with a TXV as well, as the device has the ability to "stack" refrigerant ...Superheating. In thermodynamics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling. This is a so-called metastable state or metastate, where boiling might occur at any time, induced by external or internal ...
