How to monitor/evaluate refrigerant quantity running in the cycle?
Hi everybody--recently graduated marine engineer and now responsible for maintenance of all refrig. units on bord a passenger vessel, I must admitt equations and maths arenīt just enough.
During the last 2 months iīve been solving the ocurring malfunctions by filling refrigerant and "forcing" heating coils to de-ice the evaporators in some of the freezer rooms more frequently.
At the present moment I would like to know how to determine the exact(as exact as possible) quantity of refrigerant running in each single mainline........I do I do that?
-calculations?
-can jeg meter it?
-other alternatives
...........................................best regards Ant
