Yup, I made a booboo. It is metering liquid which goes to the evap and the bulb is measuring the temp on the discharge side of the condenser before the two HXs. The desired subcooling is around 15C or even more. superheat is only a couple of deg.

I think I see what you are doing. In this way, you have a different TXV for each direction.
