Renewable energy means a source of energy which is renewable and without or with less energy consumption as possible. In the case of the earth to air heat exchanger EAHE, we can find EAHE without fan or blower and systems with it according to prevailing winds. In the present paper, an experimental investigation of the possibilities and influences of using EAHE without a fan and directly after using a fan as a mechanism of air inducing and its impact inside a hot arid region full-scale test room. Temperature and relative humidity inside a test room made of poly-wood are measured. Results show that temperature inside the test room connected to EAHE without and with external fan reduced by 10 and 14 °C, respectively. For relative humidity, it doesn’t exceed 20 to 30 % for both systems, respectively. Obtained results confirmed that fan use allowed EAHE to better thermal performance, but hygrometry must be controlled. The use of EAHE with an external fan could improve thermal comfort inside hot arid region buildings and dwellings.

可再生能源是指一种可再生的能源，并且尽可能不消耗或减少能源消耗。在地对空气热交换器EAHE的情况下，我们可以根据盛行风找到没有风扇或鼓风机的EAHE和带有它的系统。在本论文中，在热干旱地区全尺寸试验室中，在没有风扇的情况下和直接在使用风扇作为空气诱导机制及其影响后使用 EAHE 的可能性和影响进行了实验研究。测量由多木制成的测试室内的温度和相对湿度。结果表明，在没有和有外部风扇的情况下连接到 EAHE 的测试室内的温度分别降低了 10 和 14 °C。对于相对湿度，两个系统分别不超过 20% 到 30%。获得的结果证实，风扇的使用使 EAHE 具有更好的热性能，但必须控制湿度。将 EAHE 与外部风扇一起使用可以提高炎热干旱地区建筑物和住宅内的热舒适度。
