The present study conducts a comparative experimental study on the dynamic thermal response and performance of a conventional SAH and SAH equipped with PCM using paraffin packs. Various scenarios were investigated to assess the impacts of PCM usage, PCM melting point, and arrangements of PCM slabs with different melting points on the dynamic thermal response of SAHs. To this aim, two V-type corrugated serpentine SAH prototypes, including conventional and PCM-integrated ones, were simultaneously constructed and tested under field conditions. Two types of paraffin wax with different melting temperatures, 40 °C and 50 °C, with four PCMs arrangements, were installed on a SAH. The experimental runs were carried out in Kerman, Iran, for two air mass flow rates of 0.006 kg/s and 0.01 kg/s. The acquired results illustrated that utilizing PCM improves daily thermal performance from 53.1% to 62.6%. Using PCMs with higher melting point temperature results in increasing the outlet temperature of SAHs almost 5 °C, as well as the daily performance of SAHs by approximately 3%. Furthermore, experimental runs prove that an arrangement with equally distributed PCM types with different melting points has the optimal daily thermal performance and shows approximately 5% improvement in thermal performance.

本研究进行了一项对比实验研究，研究了常规SAH和配备石蜡包的PCM的SAH和SAH的动态热响应和性能。研究了各种方案，以评估PCM使用，PCM熔点以及具有不同熔点的PCM板的排列对SAH的动态热响应的影响。为此，同时构造了两个V型波纹蛇形SAH原型，包括传统的和PCM集成的原型，并在野外条件下进行了测试。在SAH上安装了两种熔点不同的石蜡，分别为40°C和50°C，具有四个PCM。实验运行是在伊朗克尔曼进行的，两种空气质量流量分别为0.006 kg / s和0.01 kg / s。获得的结果表明，利用PCM可将每日热性能从53.1％提高到62.6％。使用具有较高熔点温度的PCM可以使SAH的出口温度提高近5°C，并且SAH的日常性能大约提高3％。此外，实验运行证明，具有不同熔点的均匀分布的PCM类型的装置具有最佳的日常热性能，并显示出约5％的热性能改善。
