Underground Tube Air Conditioning
I have long heard about using buried tubes/pipes to use as a heat exchanger to take the hottter air from your house, blow it through a system of closed loop underground pipes in order to use the earth mass as a heat exchanger. The earth mass removes/absorbes heat from the house air in the pipes and delivers cooled air back into the house.
Can anyone direct me to web sites about this subject. Or, certainly, if you have knowledge about this, reply to me with it?
