本文介绍了在马来西亚的一所大学校园进行的土管冷却技术的调查。它的目的是寻求一种被动冷却替代空调。这项技术是利用地面作为散热器来产生较冷的空气，在炎热和潮湿的国家还没有进行系统的研究。在这项工作中，测量了空气和土壤温度。在地下1米处，结果最显著，在潮湿和炎热和干燥季节，土壤温度分别比最高环境温度低6 °C和9 °C。聚乙烯管埋在地下约1.0 m处，并比较了管道入口和出口之间的温降。在这些管道中发现了显着的温度下降：根据季节的不同，最高可达6.4 °C和6.9 °C。结果表明，在马来西亚提供低能耗冷却的地球管道的潜力。
This paper presents an investigation of Earth Pipe Cooling Technology, conducted in a university campus in Malaysia. It was intended to seek for a passive cooling alternative to air-conditioning. The technology, where the ground was used as a heat sink to produce cooler air, has not been investigated systematically in hot and humid countries. In this work, air and soil temperatures were measured. At 1 m underground, the result is most significant, where the soil temperature is 6 °C and 9 °C lower than the maximum ambient temperature during wet and hot and dry season, respectively. Polyethylene pipes were buried around 1.0 m underground and temperature drop between pipe inlet and outlet were compared. A significant temperature drop was found in these pipes: up to 6.4 °C and 6.9 °C depending on the season of the year. The result shows the potential of Earth Pipe in providing low energy cooling in Malaysia.
