    Hmm TRANE CHILLER 500TR - Ckt.1 daily kWh consumption is relatively higher that Ckt.2???

    Good day.

    I hope anyone can help me explain about the issue in my site:
    I have TRANE CHILLER 500TR, I connected a power meter for each circuit to monitor the daily power consumption. As observed, Circuit 1 daily kWh consumption is relatively higher that Circuit 2 with same daily running time of compressor.

    Sample daily consumption data:
    Circuit 1: 4200 kWh
    Circuit 2: 3200 kWh

    Note: Same compressor run time and circuit run time during the day.

    Can anyone explain why this happen or what is the possible causes of this issue and how I can rectify the problem??

    Are both compressors the same size (nominal tonnage)? Same age? Has one of them been rebuilt/replaced? One side could have dirtier coils than the other. Is the flugger valve working properly? Too many reasons to list especially since we don’t have a model number.
    Don't step on my favorite part of the Constitution just to point out your favorite part.

    Technically speaking, they are all heat pumps.

    It would help if you posted the model number so we know what you have. Have you performed an axial and radial bearing calibration on the compressors?
