Oooo... someone is getting defensive because they might know Im ri---ight.....
I did typo the Kw/h thing, I meant watts/hour. Sorry, I suppose I should spend more time prufe readin gmy posts because others might use it to assert that a typo means Im a total moron (not that its just a typo).
As for the rest of your post, you keep telling me I need to keep researching (I didnt know I was), and that Im wrong. Back up here man... Im trying to help you accomplish your goals here, and you are tearing me down for it. IF you know better, dont just keep claiming it and refuse to SHOW IT. Then you look like an ass trying to point the finger elsewhere. The insulating capacity of the ground outweighs its ambient temperature advantage... thats all Im saying. You are taking an above-ground radiator and burying it... which is counterproductive.
In your vast library of geothermal know-how, there are some key points Im sure you have come across. Geothermal cooling IS NOT run 24/7 in many cases. SOmetimes they are off at night, and only on during the day when it is warmer outside.... it really depends on where you live. Most geothermal setups are not for conducting heat while in use as much as they are designed to be a mass storage sink for heat (or lack of it)... which is why you see many geothermal setups with large storage containers buried underground rather than individual pipes. There are ones with pipes as well, but those are for much larger scale applications where the volume needed would be too immense, so a large area of ground is used, with pipe buried below, etc... but then you ARE talking in kw/h, not just watts. In the case of multiple pipes buried under the ground then (horizontal loop style), the major difference between those and yours (which seems to be the model you are going after) is that they space out the pipes much further and cover a much larger area. The pipes are spaced out at least a foot apart so that the soil can act as a mass storage medium. If thats the model you are going for, then you need to space out those pipes much more... you have 2-3 pipes buried where one will do the same according to that model. If you are going for the vertical model, you need to dig much deeper before you start to see the ambient temps outweigh the storage capacity of the ground.
I already explained how the ground is your weekest link in my last post multiple times, as well as just in this post. If you missed it, read it again... the soil's insulating factor outweighs its ambient temperature advantage. Why would you ask me to explain that again?
I am also not guessing for those BTU/wattage calculations. Some I can calculate from simple thermo equations, and others are just simple algebra based on the industry standard specifications used for finned pipes and heat exchangers. You are using typical internet argument tactics to win your point, but not providing any insight or proof to the contrary. If you have something to contribute to the actual discussion, you can only do it by staying on topic, not by falling back on unfounded personal attacks to discredit me in a tone that makes you seem more intelligent. I think YOU are the one who needs more time to research what geothermal cooling is all about.
