    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Not sure mind you, unless the author manages to correctly model compressor efficiency changes, evap & condensor changes, as the cycle changes.

    Would be nice to see in action.

    I had also in mind trying to locate a dynamic simulator for an hvac system. This may, however, also suffer from the same inaccuracies.

    This is where a simple circuit will be so useful. (My heat-pump lab is currently in moth-balls in Laos. Would have run some hard trials & sorted most of this out by now... )

    Peter, or MF, are you perhaps able to run some trials with your rig/system/s? It should take one day, at most, to determine what we need - at least, close enough for us to clarify Chef's dilemma.
    The plan was also measuring current and voltage and then calculating what the actual refrigeration power was (via the Bitzer software) and compared this with actual electrical power.
    We had a polynomial for the Bitzer compressor as well.
    Problem is I have the next 3 months no free minute at all. Even now, I 'm typing this while making a quote.
    We take all the work we can for the moment because I'm expecting the same problem s my colleagues have: lack of jobs.

    [at]Peter,

    Thanks so much for your input. Your proposed system sounds incredible. When you have this system up & running, I'd love to collaborate with you when everything is stable. (Would be an opportunity to visit Brugge )

    To work first - not easy times for everyone at the moment.
