Teardown of an electronic refrigerant diverter valve

Thanks to Rob for sending this for a teardown. It was pleasingly simple inside, while still allowing full computerised control of the diversion between either or both outlets.

It's fully hermetically sealed without any direct magnetic coupling, to avoid refrigerant loss through seals. I had to use the Dremel to get it open.

It's used to selectively divert refrigerant between the fridge and freezer sections of a single compressor system, but could also be used in other applications.

Unsurprisingly it uses a similar technique to the air flow diverter vanes in air conditioners.

This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
