WebSuperheated steam is steam that is at a temperature higher than the saturation temperature for the steam pressure. For example, steam at a pressure of 3 bar g has a saturation temperature of 143.762°C. If further heat were to be added to this steam and the pressure remained at 3 bar g, it would become superheated. WebWhere measured is the difference. Assuming suction superheat, a close coupled package unit would have insignificant difference. A split system can have easily have measured differences based on line size/pressure drop and temperature differences based on insulation/routing/ surrounding temps. Extended line sets with limited accessibility should ...
