How difficult would it be to do a geo-thermal like system? Instead of coolant + heat exchanger, can you just force warm air down some pipes buried in the earth (running some distance) and having the thermal exchange occur "naturally" to surface as cool air at the other end of the pipe? In which case, (solar) fans might be all that is needed to run the system (though burying the pipes would require some work)
- willyt 15y agoYou are talking about a Ground source heat pump. Once you are down about 10m the temperature of the ground is fairly constant at about 10-14 degrees C. You can exploit this temperature difference for either heating or cooling using a heat pump.
- rottyguy 15y agoIndeed though the ones I've read about uses some type of liquid coolant for heat/cool interchange. Just curious if circulating just air through the piping would suffice as a poor-mans implementation thus reducing the need for the above ground exchanger.
