蓄水蓄冷空调系统已安装在亚拉巴马州塔斯卡卢萨县的两个地点，在百货公司和阿拉巴马大学校园的娱乐中心。这两个系统都提供150-200吨的空调。这些系统在冬季利用冷空气温度冷却地下水，将其储存在含水层中，并在夏季利用冷水进行空调。这两个系统都安装在表层沉积物上部80英尺（24.9米）的无侧限地下含水层中。含水层由与流经塔斯卡卢萨的黑勇士河有关的冲积砾石和沙子组成。 百货公司系统已经运行了两年多，大学系统已经运行了一年。1983年整个夏天，大学系统都为娱乐中心安装了空调。在无侧限含水层中钻井需要大量钻井泥浆，以在钻井作业期间保持孔开。这可能会在系统运行的后期造成堵塞问题，但可以进行日常维护以防止堵塞。井的设计对于在制冷和空调循环期间促进适当注入至关重要。槽尺寸和砾石充填必须与周围地层的特征相匹配。 建议使用两个砂滤器或一个阀门系统使水双向通过一个砂滤器，以防止在冷却和空调循环中沙子和泥浆进入注入井。设计合理的钻井系统不会产生沙子，但可能会产生一些细泥浆，在较长时间内会造成堵塞。引文:研讨会，ASHRAE交易，1984年，第90卷，pt。密苏里州堪萨斯城2B

Aquifer chilled storage air-conditioning systems have been installed at two sites in Tuscaloosa, Alabama, in a department store and in the Recreation Center on The University of Alabama campus. Both systems provide 150-200 tons of air conditioning. These systems operate by using cold air temperatures to chill groundwater in the wintertime, storing it in an aquifer, and using the cold water in summer for air conditioning. Both systems are installed in unconfined water table aquifers in the upper 80 ft (24.9 m) of surface sediments. The aquifer consists of alluvial gravels and sands associated with the Black Warrior River, which runs through Tuscaloosa. The department store system has been operated for over two years and the university system for one year. Throughout the summer of 1983, the university system air-conditioned the Recreation Center.Drilling wells in an unconfined aquifer requires a large amount of drilling mud to hold the hole open during the drilling operation. This can cause clogging problems later on during the operation of the system, but routine maintenance can be performed to prevent clogging. The design of the wells is critical to facilitate proper injection during the chilling and air-conditioning cycles. Slot size and gravel pack must be matched to the characteristics of the surrounding formation. It is advisable to use two sand filters or a valving system to pass water both ways through one sand filter to prevent the passage of sand and mud into the injection wells in both the chilling and air-conditioning cycles. A properly designed well system will not produce sand but may produce some fine mud that can cause clogging over an extended period of time.
