REFRIGERATION OF A PIPE PILE BY AIR CIRCULATION.
The data obtained from this investigation indicate that the circulation of cold ambient air through pipe piles can be effective in lowering the temperature of frozen and unfrozen soil. The system created a concentrated cooling effect immediately adjacent to the pile during exhaust fan operation. Thi...
