京棉三厂位于朝阳门外红庙以东地区。地貌上属永定河冲沉扇的中下游,地下水径流条件相对较好,径流速度每昼夜1.0—2.5米。为了满足工厂夏季降温对于冷能的大量需要,每年10月15日至第二年的3月15日前后,向地下含水层灌人大量的经过大气自然制冷的低温水。供第二年六月中旬以后取用,冷能实际保存效果较好,而且在含水层中有所积累。这种现象,长期以来未能从机理上得到解释。通过工作的实践及资料的分析,个人提出一些看法。以供讨论。
Beijing Cotton Plant No. 3 is located in Chaoyang District, east of Hongmiao area. The topography belongs to the middle and lower reaches of Yongding River sinking fan, groundwater runoff conditions are relatively good, runoff speed of 1.0-2.5 meters per day and night. In order to meet the large cooling needs of the factory for cooling energy in summer, a large amount of low-temperature water naturally cooled by the atmosphere is poured into underground aquifers every year from October 15 to March 15 of the second year. Available for use after mid-June of the second year, cold energy is actually conserved well and has accumulated in aquifers. This phenomenon has not been able to explain the mechanism for a long time. Through the practice of work and analysis of information, individuals make some comments. For discussion.
