Well heat pump fans, here it is. An up close and personal look at a 410A heat pump system in action. Normal operation vs fault condition numbers in the cool cycle. There’s no audio with the vid, but for those of you who know their way around a system, the captions should be sufficient to explain what’s going on, and you should  be able to interpret the changes in vital signs. The timing per scene could have been better, so it may take a couple of  viewings to absorb the info. The heat cycle scenes are mainly to offer a “pressures vs OD temp” perspective.

And if you by chance have never seen a digital gauge/manifold RSA (refrigeration system analyzer), the top numbers are system pressures and lower numbers are either saturated temps or superheat or subcooling. All numbers are to one decimal place. You can also visit Tony B’s Digital-Zeus blog at http://digitalzeus.wordpress.com/ and see some Testo RSA tutorials for a more in-depth perspective.
