EARTH/AIR HEAT EXCHANGE COOLING TUBES: AN EMPIRICAL STUDY

摘要

This paper describes an experiment intended to discover if blowing air through buried PVC tubes can effectively assist in cooling buildings by using the relatively stable thermal mass of subterranean soil to cool the air. Three different lengths of earth/air heat exchange cooling tubes at a 10 ft. (3.05 m) depth in semi-arid Lubbock, Texas,are compared. Initially a 100 ft. (30.48 m) and a 200 ft. (60.96 m) tube were constructed and monitored. Later the two tubes were connected making it possible to compare their performances to that of a linked 300 ft. (91.44 m) tube.
