冬季的冷空气用于在长期的地下储存中产生相对大量的冰。冰的储存冷却能力将在接下来的夏天恢复。初步研究表明，在冬季足够寒冷且持续时间足够长的地区，这种系统可以提供夏季空调、制冷或工艺冷却。在1983年11月17日至1984年3月6日期间，系统运行1013小时，冻结了4000 ft3（113 m3）的饱和土壤蓄水量。1984年仲夏期间，冷却恢复操作总共运行了32天。在此期间，回收了743吨小时的冷却或8921856 Btu（2613 kWh），估计剩余存储冷却容量的5%至8%。 然而，所有的冰都融化了。大约52%的储存能量已被回收，表明周围地球可能损失45%至50%。引文:研讨会，ASHRAE交易，1985年，第91卷，pt。1B芝加哥

The cold air of winter is used for producing relatively large amounts of ice in long-term underground storage. The stored cooling capacity of the ice is recovered during the following summer. Initial research indicates that in regions where the winter is sufficiently cold and of sufficient duration, this type of system could provide summer air conditioning, refrigeration, or process cooling.The water-saturated earth storage mass of 4000 ft3 (113 m3) was frozen with 1013 hours of system operation between the dates of November 17, 1983, and March 6, 1984. During midsummer 1984, the cooling recovery operation ran for a total of 32 days. During this period, 743 ton-hours of cooling or 8,921,856 Btu (2613 kWh) were recovered with an estimated 5 to 8% of the stored cooling capacity remaining. However, all of the ice had been melted. Approximately 52% of the stored energy had been recovered, indicating a probable 45 to 50% loss to the surrounding earth.
