EARTH-COUPLED RADIANT HEATING AND COOLING SYSTEM FOR HOT, HUMID CLIMATES.

Author(s) : AKRIDGE J. M., CLEAVELAND J. P., KEEBAUGH D.

Summary

A SUPERINSULATED RESIDENCE HAS BEEN CONSTRUCTED AND TESTED IN ATLANTA, GEORGIA. IT IS DIRECTLY COUPLED TO THE EARTH THROUGH THE USE OF EARTH-SIDE AND HOUSE-SIDE HEAT EXCHANGERS. THE EARTH-SIDE HEAT EXCHANGER CONSISTS OF 3 WELLS DRILLED 46 M DEEP. THE HOUSE-SIDE EXCHANGER CONSISTS OF 46 CONCRETE PANELS THROUGH WHICH EARTH-COOLED WATER IS CIRCULATED AND WHICH SERVE AS INTERNAL WALLS. EXPERIMENTAL DATA AND COMPUTER SIMULATIONS HAVE SHOWN THAT A SIGNIFICANT PORTION OF THE COOLING LOAD IN THIS CLIMATE CAN BE CARRIED DIRECTLY USING THE COOLING CAPACITY OF THE EARTH WITH NO MECHANICAL ASSISTANCE. RADIANT HEATING AND COOLING IS PRACTICAL FOR HOUSES IN HOT CLIMATES WHERE THE LOAD CHANGES FROM HEATING TO COOLING IN A RELATIVELY SHORT PERIOD OF TIME, IF THE HOUSE IS ENERGY EFFICIENT.
