The cooling load would be about 3 ton the old 2 ton air to air couldn't keep up with the machines running.

The air handler I had rescued from the scrap dealer was a refrigerant slant coil with an additional hot water exchanger. I had converted the slant coil to water by removing the cap-tube and installing a water manifold. So there is actually 2 heat exchangers (water to air)in the handler.

Before the hacked heat-pump was made the ground loop was installed. I had tried an experiment, to pump the ground loop water (12 Deg.C) through the air handler, to air condition the shop. Although condensation poured from the coils and the temp did drop it wasn't enough. The result was shop air temp of 26 deg. C and almost 100% rel. humidity.

I understand now one would require coil temps much lower to wring out as much moisture as possible.

5 tons of cooling should do-it. With the glycol I should be able to get near zero coolant through the coils. I'll keep the renovators posted.

Mike and I are in-contact for this and other projects of interest.
