Upon further study:

https://en.m.wikipedia.org/wiki/Radiant_cooling

I think that I could use the buried outside loop to cool the downstairs slab (1440ft2) using the Pex loops designed for heating (7” OC)

Cooling needed about 4 weeks a year.

Climate is dry so this might work, I would need to avoid condensation.

It would be easy to tie into the radiant slab loops with a flat plate heat exchanger & pump the buried loop controlled by a greatroom thermostat and a dew point controller.

I haven’t found any heat pumps under 1/2 ton?
