    Trane RTHD Question?

    Hello All,


    I am looking at using the head pressure control option on a RTHD Chiller and I am looking for some clarification.


    I have used TechView to change that option inside the CH530, but I am not understanding exactly how the chiller itself determines the flow needed? Where does it source its information for Max Flow/Min Flow/In-Betwixt Flow???

    Any help is appreciated.


    TIA

    it controls the water flow based on refrigerant pressure differential.

    It doesn't look at water flow. It is monitoring refrigerant differential as Mr. Jay stated, no differential no oil movement.
