ABSTRACT:
A heat pump for cooling or heating a conditioned space includes an underground heat pipe laid into a hole in the ground back-filled with soil. The heat transfer of the soil is improved by dispersing highly water-absorbent hydrophilic polymeric gel particles soaked with water around the heat pipe. The water-soaked particles preferably are coated with a water-impermeable film. The water may also be entrapped in liquid form in small bags. Also, a water impermeable sheath may be formed around the back-fill soil to minimize evaporation from the particles.
