Pump down principle

    "Pump down" principle

    A building has a storage room that needs to be cooled. This cooling-system is to be controled using the "pump-down" principle. I have absolutely no idea what this implies! Anyone...?

    Not me, lad. Sorry. I might be familiar with the process, but not by that name.

    Do you mean pumping down to a vacuum? Or do you mean pumping down the refrigerant? (pulling the refrigerant out of the system).

    You might want to check some of the HVAC sites or eng-tips.com.
