T.E.V. adjustment.

When we say the superheat is high, what are we really saying?

Are we saying that the coil isn't being fed enough refrigerant for the load?

Or are we saying that the load is too much for the amount of refrigerant being fed?

Think about it. This is just two ways of saying the same thing, and the problem could be either load or feed.

When we say the superheat is low, what are we really saying?

Too much refrigerant for the load? Or not enough load for the refrigerant?

Again, the same thing, and the problem could be either load or feed.

Or both.

There is more to superheat than just turning that stem.
