I want to build a small geothermal cooling unit to cool one small room in my house. If i lay 0.5" pex pipe which is 0.475" ID.
The big question is how long does the water flowing in the pex tubing have to stay under ground. Constant ground temperature is about 55 degrees F around my house. I have red clay around my house. I know that the temperature as a function of time is a exponential equation.
Can somebody give me an equation temperature Vs. time spent under ground. This way I can calculate the time needed to get the right temperature water coming out of the pex tubing. Here is as many specs as I think can effect the equation:
Pex ID = 0.475"
Red clay soil
constant ground temp = 55oF
average water temp flowing into loop = 70oF
