Finding actual superheat or subcooling is easy . Simply hook it up to the system, let the system stabilize, and get your actual superheat or subcooling reading in real time. No charts, no calculations. It’s all done for you in the instrument.
I'm curious what the load on the evap was.On 70 degree days. I see a lot of R410A systems running at or around 110/280. So why did you add gas. Was the SC low, or the SH high?
R410a at 110 PSIG is 36 degrees saturation. Roughly equal to 63 PSIG with R22.I'm curious what the load on the evap was.
110 is just a tad low, but you are right, I see many running at that pressure (which I think is right around 32 degrees) if there is no load on the evap.
Fairly certain the unit is overcharged now.
True.R410a at 110 PSIG is 36 degrees saturation. Roughly equal to 63 PSIG with R22.
Good chance its over charged. Specially if that condense has a micro channel coil.
