someone asked about large scale heat pipe applications? how about a heated driveway that is powered by the earth?

https://pangea.stanford.edu/ERE/db/W...2015/29041.pdf

By the way I love this thread. What's the lowest Hz you've run the compressor at? from what I've read on split systems (mini or full size inverter systems) there's a minimum speed, and separately a minimum speed that must be run occasionally to achieve good oil return. is this just not an issue on a system so small (pipe-wise, not capacity)?

I'm also wondering if you've considered the need for a receiver. is this unnecessary again? or perhaps effectively included in the volume of your bphx/dryer? some of the refrigeration machines I've seen have receivers nearly equal in volume to the compressor housing itself.

If there's any more details you'd like to share on the operation of the VFD than what you've posted so far, I'm very curious to hear it.

Fellow eco-renovators.

Thought I would issue a milestone. The DIY shop heatpump has now been operating since October 29 2014 without any problems what so ever!!! That’s 5 yrs trouble free. In fact I have gained so much confidence in the system I left it operational for a month keeping the shop at 16 deg C while away for vacation

Heating and air conditioning all the while sipping electrons. It was a very trying build but the outcome has exceeded my expectations

Eco renovators. This past 12 hrs we have outside air temps of-20 deg C And all my heat- pumps are flexing their muscles. Miserly sipping electrons sequestering heat stored 2 m deep in the ground from the previous sunny season warming our feet on the hydronic floor.

In these cold temps the houses 3.5 ton is running flat out as it was sized appropriately. To be completely honest it is loosing a little ground but during the day with a little sun coming in it quickly catches up

I find it odd when I hear someone wanting to retain their NG unit or what ever for back- up. A properly sized HP is all that’s required. Maybe it’s just nostalgia???

Or maybe they don't trust their heat pumps. Since R410 replaced R22 the number of evaporator failures has gone though the roof. Manufacturers know what the problem is and they know how to correct it. They and the installers have no desire to correct the problem.

Warranty doesn't cover labor so the installers are happy charging $600-$1200 to replace a coil. Manufacturers are OK with sending out coils that cost them $50 knowing the customer will probably buy a new unit after the third coil. Do they care if the customer goes with a different brand? Not if all of them have the same issues.

Salesman: If you are unhappy with your Goodman we can sell you an Amana (same product, different paint).

Isn't that why we started hacking these things in the first place?
