What are the reasons for the rapid pressure increase in the lithium bromide self-priming device?
Thread Content
The self-evacuation pressure of lithium bromide units rises too quickly, forcing frequent vacuuming; this also affects the cooling efficiency. Has anyone encountered a similar issue?
I haven’t encountered a similar situation before.
1. Check the instruments. 2. Check the sealing of the vacuum pump and ball valve
From the temperature difference between the water cooling inlet and outlet, it can be seen that the instruments are showing accurate readings. The vacuum pump functions properly and there are no leaks in the valves; however, it is clear that a large amount of air has entered the system, as a lot of air is being drawn out, though it’s not known where the leakage is occurring.
So, what is the overall sealing performance of the refrigeration machine?
Our unit’s lithium bromide chiller system draws negative pressure once a week, for 6 hours each time.
The overall sealing is in place, and the leakage points have been identified
It was caused by the leakage points in that area; solve it
Check for cracks in the copper tubes of the generator or for perforations in the high and low pressure exchangers
