Anyone using earth cooling tubes to cool there garage?

I have not seen many of these systems.My niebors house uses this. It does not keep it cold in the house, but it keeps it fairly cool. Anyone else using this type of system?

You're referring to a *Geo Thermal* system. Some of the key points to consider is the ROI (return on investment). If you plan to live in the home forever then its not relevant.

If you plan on living in the home for less than 5 years you will never recoup your investment.

If in your region electricity is very high, then again installing a Geo Thermal system will not pay off as you would expect. Just something to consider before you go forward in this pursuit.

After this past summer of record highs, I have been looking at a cooling system for the garage. I am looking at a newer inexpensive geo-thermal system. The cooling tubes are buried in a trench 3-4 feet down out in the yard instead of the 100-200 foot shafts. This makes it easily done by renting a trencher and doing the lines yourself. As it is only for the garage, any help from the heat would be an asset.

3-4 feet down is no where near deep enough if you live in the South. AX, NM, TX probably need to be 10' or more !

In some parts of the Australian outback, people live in old gemstone mines. 10-20 meters down !

I think my neighbors is about six feet down and about thirty feet long.

Check out this site - it describes how to build a simple relatively inexpensive system to cool a building. While not scientific in approach I wanted to see if this would work. I have an 80' run of 4" PVC for my sump pump and one summer just to see if this worked I had a small fan blowing through it and the air coming out the other side was about 55 degrees. The pipe is down at the frost line which is 42" in my area. The outside temp was 85 degrees and the air going into the tube from my crawl space was 72 degrees. From what I have seen, this system would work. I just have not gotten around to digging up my lawn yet.

do you mean a passive geo system ?? relatively large diameter pipe system buried below the frost line that has a fan in one end ???

yes i have seen that used to cool a dairy barn .. works very well if you have enough acreage to keep the system balanced
