Suction Pressure 90. Suction line temp 54. inside temp 75. wetbulb 69. So ive been thru this problem b4 with the low head high suction so i assume piston or a-coil . I open up the duct and the other hvac guy has put in a 3ton acoil . I told the neighbor that he should replace the acoil with a 2 1/2 ton .

Jun 14, 2012 · I went to do a maintenance on a 410A Trane system today, when I came up on the trane I noticed it was running like a 450 pound head pressure, the first thing i thought was why in the world would it be so high, so I cleaned the cool, checked filters, checked txv bulb position, everything checked out although there were some minor …Outdoor ambient temperature. Typical low pressure or suction side pressure for R410A is about 120 psi,varying by ambient temperature,here assuming 75°F,may vary by equipment and metering controls. Typical high side pressure for R410A is < 600 psi at an ambient outdoor temperature of 95 °F,may vary by equipment.The liquid line pressure at 108°F saturation temperature is 356.5 PSIG. This screenshot of the Ref Tools app shows the liquid line pressure of R410A at saturation at 108°F. Notice how the slider has been set to BUBBLE point (inside the orange box). Vapor Line Pressure: Again, we already have the return air temp data, which is 74°F.Aug 24, 2016 · If the suction pressure is 45 psi, (which converts to 22 ° F) and the suction temp is 32 ° F, the system still has 10 ° F of superheat. The fact that these readings are normal indicates the low suction pressure is not caused by low refrigerant, but insufficient heat getting to the evaporator. CAUSE #2: Defective, plugged, or undersized ...This is the pressure in the air conditioner's refrigerant suction line (low side pressure during compressor operation) and this will be a relatively low number, often less than 100 psi. During operation, refrigerant is returning to the compressor from the cooling (evaporator) coil in this line.

Before I go and charge it to 155, can someone confirm that I'm reading this chart correctly? And is "suction pressure" the pressure of the 410A in the line? I know all units operators with different pressure ...
