Ground loop water dehumidifier?
I'm considering tapping into the return line from my loop and plumbing in a small copper water/air HX with a fan. A dehumidistat would turn on the fan whenever necessary.
Has this been done? Are there any good reasons not to? |

The latest examples of this principle are in the heat pump food dryer thread. Many ecorenovator members made working units that dried herbs, fruits, and even made jerky. The machines work great! |

Something close: During a hot summer Daox used his basement's sump to cool the house. A side effect was condensation of humidity.

The temperatures are in my favor for sure. If I remove the insulation from a section of the loop piping, it readily condenses water. My loop water is around 46 degrees and I keep the air temp between 62 F - 66 F.
Currently I'm running a dehumidifier based on a 5000 BTU/Hr window AC. It uses around 480 Watts but does a great job. I am considering this loop water dehumidifier as a way to reduce that 480 Watts to perhaps around 100 Watts (the power used by a small fan). |

So you want to A/C with loop water
Techshop
Tried it. Didn't work very well. The HX temp of 45 Deg. F isn't cold enough to remove humidity to make you feel comfortable. The room will have slightly lower temp., intern the air gets closer to the dew point and we start to feel uncomfortable. You require a colder evaporator to wring the humidity out and feel comfortable. Stick with the heat-pump air-conditioner. They work so well in the summer.!!! Notice the frost on the tube of my air handler. This is in my well insulated shop with machines producing heat. The Geothermal HP is awesome. AND I don't notice the extra cost on the electric bill. It is cheap to operate.!! Randen |
