UNDERGROUND AIR TUNNEL SYSTEMS \nAn open loop, underground air tunnel system cools \nor heats the ambient air passing through it. This air is \nthen introduced directly into the conditioned space of a \nbuilding. In order to reduce the required tunnel length, \na closed loop system may be used. In this system, the \nair from the conditioned space, with some ventilation air, \nis recirculated through the underground tunnel. Open \nand closed loop systems can be useful for air \nconditioning agricultural buildings. However, the threat \nof air contamination from any possible bacterial growth \nNormally, heating and air conditioning systems have \naverage year-round COPs of about 2.0. However the \nCOPs of the systems utilizing underground air tunnels \nare much higher. For open and closed loop systems, the \nCOP can be as high as 10. By doubling the COP over \na conventional system, the energy input (energy that one \npays for) is reduced by 50 percent. \nIn addition to energy conservation, this technique \nalso increases the capacity of a conventional system.

Well, get out your heat transfer text book and start calculating. You should have all the info you should need.

ok remember that freon or r134 are used in AC but is not like it is a substance that stays cold... you to compress it in order to make it liquid and then it absorves heat and evaporates completing the cycle... if you are looking for a sort of system that will make something stay cool.. .hmmm man it is called Air Conditioned

ASHRAE is the organization that publishes the standards by which heating equipment is sized and vented.  They charge for their publications however.\n\nTalk with a reputable boiler manufacturer like Paterson Kelly or Hydrotherm and they will probably give you some guidelines for no charge.
