:mad: So i have been working on a couple denco units in a film storage room , the dencos run on R134a and due to the nature of the room and whats in it , the units have also been fitted with a hot gas bypass to make sure the humididty stays low.
We have just finished the first, it had lost all its gas due to a few leaks in the system, but thats all sorted. I i recharged the the first unit to the sight glass and ended up adding 3.1kg of gas, unit works perfect clear sight glass and cooling nicely.
So we then moved on to the next unit wich was running but the sight glass was stuck at half and not clearing, i assumed another leak right? ...... wrong!!!
I i actually ended up recovering 4.6kg of gas out of this system even though the pipe leanghts for both units are the same +/- 1m or so.
Tested the system no leaks.
So my question is..... what could be coasing the sight glass to flash? The only thing i can think of is the dryer and as we speak we are changing that so it might fix it or not, just wanted to see if anyone had any other ideas .......?
thanx
