The TXV also needs a proper pressure drop (about 100 PSI); without that pressure drop, the TXV can’t do its job properly. When the suction pressure is low, the technician should take the subcooling and superheat inside and outside. The goal is to look for the temperature differences between the inside and outside measurements.Jun 24, 2011 · High Suction Pressure! I have a 3Ton Carrier Heat Pump unit using 410A that has extremely high suction pressure around 250PSI.

This time, near the condenser. Then take the head pressure in Psi and convert it to the temperature on the pressure/temperature chart. Assuming you are dealing with a R22 system, let’s say the head pressure is 260Psi. This will convert to 120F. R410a suction pressure may be around 120psi, and R410a head pressure may be anywhere from 225psi to 350psi. Many conditions could apply here, there’s absolutely ‘no’ set point pressure for 410a, r22, or anything else. Educate yourself on whats going on in the heat transfer process.
