Hello everybody,
The IQF is -40 C ET, and the storage room is -31C ET with -25C room temperature. They share one liquid and wet suctoin line. Could I just let them share one same ET -40C. I think this will not cause any problems. The room doesn't have any humidity requirements. Do I need to add one back pressure valve in the -31C evaporators' outlet and is practical to add the suction pressure valve in the wet return line?


Thanks in advance!!
