Hi, John Howie

Welcome to RE

can anyone help me with low suction super heat problem 2x sabroes runs 8x diff size room with diff temps units set to cut out at 2.1 bar pm.valve on each room but during night when theres no load unit trips super heats on each room are fine could this be with liquid sitting in lines on start up when one room calling for cooling

Can you explain this in plain english, please?

Also can you tell us something more about your compressors, refrigerant, set points, PLC if any and so

Best regards, Josip

Is this a direct expansion system (sounds like that) or a pumped circulation system.


Probably TEV's not EEV's, wouldn't be uncommon with TEV's especially with low loads and the valves not just selected with this in mind.
