Re: Strange TXV setup
I have had a look on the danfoss site does not give superheat control limits (adjustment) but does give varying detail to open 11C SH to open to design. This then shows that you would expect frost. Also valves do not close 100%, so present valve could be giving 1KW of load at maximum shut down, which likely to be greater than the plate load, thus liquid floodback may occur.
The present orifice matches chefs equivelent compressor duty (which practically is not as high as he predicted) I am not saying it has not migrated, but neither would i presume it was.
