HAS ANYONE HAD ANY EXPERIENCE WITH EPR VALVES ON A/C SYSTEMS
HAS ANYONE HAD ANY EXPERIENCE WITH EPR VALVES ON A/C SYSTEMS
(OP)
I HAVE COME ACROSS RESIDENTIAL A/C SYSTEMS THAT ARE OVER SIZED AND /OR HAVE UNDERSIZED DUCTWORK THAT IS SOMEWHAT UNCHANGEABLE I'VE OFTEN WONDERED IF AN EVAPERATOR PRESSURE REGULATER WOULD PREVENT THE EVAP COIL FROM ICEING WHEN USED W/ A TXV HAS ANYONE TRIED THIS? ANYONE?

This is a very repeated and always the same old story!
Keeping the TXV, but changing its orifice to a smaller diameter or change the valve to a smaller size. Then check carefully the compressor response, measuring all the electrical parameters, as well the thermodynamics ones. Also you have to decrease the air flow rate, changing the fan operating conditions, according, by the regular/known means.
Good luck

One disadvantage to the configuration you'e suggested is that the compressor will be pulling down needlessly to a lower pressure.
