Re: Strange TXV setup
Most compressor manufacturers call for a minimum of 8-11K SH at the compressor inlet. At 2psi, the saturation temp is about -27C. If we add 8-11K SH, that gives us a minimum suction line temp of 16-19C at the compressor inlet. At those temps we would expect frost all the way back to, and maybe even on the compressor.
In truth, the suction line temp could be even lower, down to about 5C, without causing any damage. Frost at the compressor inlet does not necessarily indicate flooding.
