Subtract the Liquid line Temperature from the Liquid Saturation Temperature and you get a Subcooling of 15. “Typically” on TXV systems the Superheat will range between 8 to 28 degrees with a target of about 10 to 15 degrees. The Subcool range on TXV systems will range from about 8 to 20.
How do you test superheat and subcooling?
- Measuring Superheat.
- To measure suction superheat, attach your gauge manifold to the suction service port on the outdoor unit. ...
- Measuring Subcooling.
- To measure liquid subcooling, attach your gauge manifold to the liquid line service port.
Where do you measure superheat?
To measure evaporator (indoor coil) superheat, first measure the suction line temperature at the evaporator outlet. Next, measure the refrigerant pressure at the suction line of the indoor coil.
