Wrap your thermocouples with insulation to. Lack of airflow across the evaporator will cause the evaporator’s superheat to be lower than normal. I have some general questions on superheat and subcooling for walk in coolers and freezers, i am not working on a walk in right now that i can refer to just want to gain a little more understanding. Do not use the common suction pressure port on a heat pump. To find the superheat, always subtract the saturated temperature from the actual temperature. Set the defrost time and verify the defrost initiation settings.

To measure suction superheat, attach your gauge manifold to the suction service port on the outdoor unit.

If a system with a receiver has high superheat and the liquid line sight glass is full of liquid (no bubbles), check the metering device. Also, check all gauges to be sure temperatures, subcooling, superheat, and pressures are all normal. Check your pressures and relation to saturation temperature in relation to box temperature. Procedure below is a procedure for calculating an evaporator’s superheat value: Go back to basics, check your superheat and subcooling. See corrective steps for low suction pressure.
