Hi Steiner,

I don't need any encouragment This one will run and run. Longer than Les Miserables!

I was thinking more of the larger many hp motors operating large air handlers etc.

Now those are a problem. Just as bad if not worse is when TXV's are used on VAV (variable air volume) systems. I saw one of these years ago and the compressors had already been changed about 3 times before I was called to look it.

.... the lack of understanding of superheat, subcooling and valve selection that are our biggest problems. In other words adequate training.

No argument from me. This is why I said don't adjust the TXV's in the first place. People adjust them for the wrong reasons most of the time. I was hoping someone might think twice before they adjusted a TXV and would spend some time thinking about what they were doing.

I have been looking for a lively discussion for a while.

Do not be afraid to join in the fun. You did not strike me as the bashful type.
