本章介绍了Sanusi（2013）发表的工作中的低能量土壤-空气换热器（EAHE）在炎热潮湿的马来西亚冷却性能的扩展探索。越来越多的空调冷却目的的需求，促使这项调查，寻找更好的冷却替代品。被动式技术，即利用地下土壤作为散热器产生较冷的空气，在炎热和潮湿的国家还有待进一步研究。这项工作，被动技术，进行两个相互关联的实地调查：土壤温度测量和接地管冷却实验1年的测试。在一年中，1 m深度的土壤温度分布是波动的，受一年中不同季节的影响。然而，在雨季，1米深的土壤比更深的土壤更凉爽。因此，为了调查1年的EAHE冷却性能，在相同的测试地点将管道埋在1 m深处。在1米深的埋管中发现了显着的温度下降：分别为6.3和8.6 °C，一年中的季节。采用Khedari热舒适图对埋管出口空气温度进行热舒适性分析，结果表明，埋管出口空气温度在湿热国家热舒适条件范围内。这项研究表明，在马来西亚的建筑物中提供低能耗冷却的地下管道冷却技术的潜力。
This chapter presents an extended exploration of the performance of low-energy earth–air heat exchanger (EAHE) cooling in hot and humid Malaysia from the published work of Sanusi (2013). The increasing demand of air-conditioning for cooling purposes motivates this investigation in search for better cooling alternatives. The passive technology, where soil underground was used as a heat sink to produce cooler air, has yet to be investigated further in hot and humid countries. This work, the passive technology, is tested by carrying out two interconnected field investigations: soil temperature measurement and the earth pipe cooling experiment for 1 year. In 1 year, soil temperature distribution at 1 m depth fluctuates, influenced by the different seasons in a year. However, the soil at 1 m depth is cooler than deeper soil during the wet season. Therefore, for investigating the EAHE cooling performance for 1 year, the pipe was buried at 1 m depth at the same test site. A significant temperature drop was found in the 1-m-depth-buried pipe: up to 6.3 and 8.6 °C, respective to the seasons of the year. Thermal comfort of air temperature at the buried pipe outlet was analyzed with Khedari thermal comfort chart, and the result has shown that the buried pipe outlet air temperatures are within the range of thermal comfort conditions for hot/humid countries. This study has showed a potential of earth pipe cooling technology in providing low-energy cooling in buildings in Malaysia.
