Default How my Sanyo is keeping me warm..

I was watching this video, as I was looking at the diagram below..
The Animated Cycle - YouTube
The location of the coils, (left & right) corresponds nicely to the diagram.


And, since my Condenser coil is on the left in Heating mode, and the Evap coil is on the right,
it was easy to understand the explanation (as it applied to the Sanyo).

The dotted lines are the heating cycle. I think now, I can understand why
the "narrow tube" is used on the Liquid Line and the wide tube needs to be
wide, so it can handle the volume of high pressure gas.

Maybe someday, the box labeled Indoor Unit will be a gas-to-water HX. (For the Repaired Sanyo outdoor unit).

I had to sit and think a while before I finally understood the flow in both directions. Thanks.

For a guy interested in this topic, my understanding of heat pumps is pretty basic.
I had to pause and rewind a few times, (I'm old) and make some notes on my diagram,
but things are clearer now. It's a lot easier to look at my system and visualize
the 'flow' of the R410A and know what state it's in, on which side of the Expansion valve etc.

I'm in the middle of testing the repaired outdoor Sanyo unit,
so it's nice to know more about how things actually work,
instead of looking at it as a Black-Box, as is often done in the electronics field.
