We have 6 low pressure centrifugal chillers (R11). Oil migration has always been an issue. I recently came across Oil Acid & Moisture Purger (Oil Separator) Models OAM-LPC200-11/113 & OAM-LPC200-123. Has anyone installed one of these and what do you think about it. Any issues that you can think...
one of the trane centrifugal chiller capacity is limited on high current (99%). condenser pressure is at 8.5 psig. Entering water temperature (condenser side) is 77 deg F. Also, inlet guide vanes are open 85 %. I suspect that there is oil in the evaporator tubes. Sight glass is to the top (cant...
1. At a recent training provided by carrier, intructor told us that the vane position and amps are directly propotional. If the load is 80 % then amps should be 80 % too. We has Trane R11 and R113 centrifugal chiller that do not work like that. Amps may be 95 % but vane position can be 70 %...
We have a issue with one of our chillers and I am hoping that someone can shed some light on it. One of our R11 Chiller is showing low condenser leaving water temperature and high Condenser approach. Here are the specs taken yesterday.
Condenser entering water temp = 34.6 F
Condenser leaving...
I work with low pressure Centrifugal chiller (Trane) that is showing that it has exceeded the high condenser pressure. It has been in standby for last couple of months. It could be a sensor problem. but is there any other explanation for this. Thanks in advance.
