Static superheat is the superheat at which spring force is met and the valve is ready to open. 2. Opening superheat is the amount of superheat above static superheat that opens the valve to allow refrigerant flow. The superheat measured at the outlet of the evaporator is the sum of the two and is called operating superheat.The high head leads to poor heat rejection and the higher pressures can force more of the available refrigerant into the evaporator and show up as normal or high suction pressure with normal or low superheat. Also make sure the outdoor fan motor is running in the proper direction. Reply.
