Hi Guys,
It's been a while. I was wondering if anyone has experience with these systems or similar. Problem is we are getting 0 degrees suction temp back at the comp yet only 12 degrees on evaps. These systems have multiple evaps of varying capacities and our main problem is the 56kw condensing units breaking discharge pipes, compressors etc due to liquid return to comps. All evaps have Electronic TXV's (stepper type). We have installed these systems in many places around Australia and have never experienced this problem. I even had Midea on site and am waiting on there suggestions from the data they took. The valves do shut down and they are not overcharged. BTW the o/door units are on Level 4 (roof) also.
Look forward to some ideas, cheers :)
