Research on an air-conditioning (AC) system that uses soil as a heat storage is still not widely conducted in Indonesia. The soil functions as a hot or cold storage medium by flowing fresh air through a heat exchanger due to its constant temperature tendency throughout a year. Earth-air exchanger (EAHE) application was simulated and got the results that soil with a volume of 12 m³ is potentially used as a heat exchange medium with a heat transfer surface area of 24.4 m². The EAHE cooling capacity obtained is 1,002–1,282 watts depending on soil condition. Increasing the pipe diameter and airflow velocity decreases the average temperature difference by 42.9% per inch and 47.2% per m/s, respectively. Meanwhile, increasing the pipe thickness and soil depth increases the average temperature difference by 1.59% per millimeter and 6.06% per meter, respectively. The pipe interface distance recommended is greater than or equal to 200 mm. The EAHE can meet the Indonesian National Standard thermal comfort standard and ASHRAE breathing zone outdoor airflow for ventilation standard but can only meet 23.5%–30.0% of simple house-cooling loads. It consumes 75.8% lower energy and has an 139%–230% higher coefficient of performance than a split AC system.

在印度尼西亚，对使用土壤作为蓄热器的空调 (AC) 系统的研究尚未广泛开展。由于全年温度趋于恒定，土壤通过使新鲜空气流过热交换器而起到热或冷存储介质的作用。模拟地-气交换器（EAHE）应用，结果表明，体积为12 m ^{3 的}土壤可用作传热表面积为24.4 m ²的热交换介质. 获得的 EAHE 冷却能力为 1,002–1,282 瓦，具体取决于土壤条件。增加管道直径和气流速度可使平均温差分别降低 42.9%/英寸和 47.2%/m/s。同时，增加管道厚度和土壤深度，平均温差每毫米增加 1.59%，每米增加 6.06%。推荐的管道接口距离大于等于200mm。EAHE 可以满足印尼国家标准热舒适标准和 ASHRAE 呼吸区室外气流通风标准，但只能满足 23.5%–30.0% 的简单房屋制冷负荷。与分体式交流系统相比，它的能耗降低了 75.8%，性能系数提高了 139%–230%。
