Hi, I am trying to adjust the charge of an R410A AC system which uses a piston metering device. I measured indoor wet bulb and dry bulb as well as outdoor dry bulb temps and got a calculated superheat of 24F which seems high to me. I'm in Texas so it's pretty hot and humid. Temps for target calculation: Indoor WB: 71 measured right below air filterLINE TEMP. - SAT. SUCT. TEMP. Saturated Suction Temperature Pressure Sat. Evap. Temp.

Somehow a 036 unit goes from 12 SC to 4 SC without any changes to the product. So I am charging a 13ACX-036 per the new label at 4 SC.

Figure out if the AC line set or a reusable freon bottle contains R454B refrigerant. Differentiate between R454B and other refrigerants, like R22, R410a, and so on. Use it to calculate the required R454B superheat and total superheat.

Input these temperatures in a superheat chart, calculation, app, or digital manifold set in order to determine the ... A: First, take all of your refrigerant readings and your liquid line and suction temperature at both ends (on a split system). This means superheat, subcooling, suction saturation (evaporator coil temp), and liquid saturation (condensing temp). For a TXV to do what it is supposed to, you need a full line of liquid before the TXV. ….
