    Danfoss parellel scroll compressors



    Who have used Danfoss parellel scroll compressors?
    Any comments? per the catalogue,it's only needed to add a set of piping assembly,what you do is same as common single compressor. I ask for Sanyo, it looks more complicated.

    Danfoss, you mean Manneurop.
    In order to have compressors in parallel you'll need three manifolds: one common manifold for discharge, one for suction, and an oil balancing pipe.
    I don't know whether manneurope supplies those pipes, as their guys do not have the welding patents for lap joints brazing.

    Dear lc shi,
    It's not an ordinary piping assembly. It consists of some discharge T's, an oil connection and on the suction side an oil separator/restrictor. This last one takes care of the 'dynamic oil balncing system'.
    Take a look on the attachment. I hope it's clear, otherwhise contact your local danfoss office and ask for the leaflet 'Selection & Application guidelines' for Performer Scroll compressors. (If not available, I can PM it to you).
    You can mount these compressors in tandem, trio or quatro. (2, 3 or 4 identical parallel). 3 and 4 : only for models SZ160 and 185.
    Best regards.
    Bruno
