Hi to all, It's been awhile. I'm working on a super custom display. It's physical shape and finish were designed by someone who gave little thought to the eletcric and refrig that will be required, so space is very limited. There is very little compromise to gain more room for the mechanicals. The difficulty I have now is this:
A TEV located where I have space, is feeding an evaporator for a small self select box. It will then exit this lower evap go up, 3 feet total, to the top of the cabinet, wrap several times around a stainless steel box,which will be insulated, making it a cold pan. Then back down to the starting point, near the TEV and out to a remote location. The sensing bulb and EQ tube will have to be two feet from the outlet of the cold pan. There is no space to get it closer. I plan to insulate the outlet of the lower evaporator line to the inlet of the cold pan. Then of course I would insulate from the outlet of the cold pan back to the remote condensing unit.
I have done this sort of thing before with surprisingly good results. I was able to maintain excellent temperatures in both the self select and the cold pan, which is used for condements- veggies and such, temps not critical, by only controlling the self select and allowing the pan to flood with out it's own control. What I have not done is place the sensing bulb and EQ so far from the outlet.
Any thoughts? One of a kind Ken
