Got a call to a big walk-in beer cooler not holding temp (45°F). Looked at copeland semi-hermetic first. Head frosted and discharge line luke warm. (floodback)
Each evap had its own LLSV and T-stat. So i shut off one evap and adjusted TXV for 8 degrees SH on running one and then i shut off that one and adjusted other for 8 degress SH. Is this how you guys would approach this sitiuation or would you adjust them while both of them were running?
