空气型相变储能装置（AT-PCESD）与空气进行热交换，并利用相变材料（PCM）的潜热。双S沟道AT-PCESD可以单独存储和释放热量，缩短了器件的长度。采用数值模拟和实验验证相结合的方法分析了其热性能。比较了S形通道和直通道的差异，并进行了多工况模拟，以探讨空气温度、流量和相变材料导热系数的影响。此外，还分析了蓄放热同时工况下放热切入时间对蓄冷器热性能和蓄冷量的影响。提高PCM的热空气温度、流量和导热系数，可以缩短不同特性的储热时间（9.3-51.2%），并且对储热能力影响很大，约为26，000 KJ。增加流速可以增加蓄热和放热速率，其中4 m/s是最佳流速。当储存温差大于排热温差时，开启同步储存和排出条件可以继续增加液相率。
The air-type phase change energy storage device (AT–PCESD) exchanges heat with air and uses the latent heat from the phase change materials (PCMs). The dual S-channel AT–PCESD can store and release heat separately and shortens the length of the device. Both the numerical simulation method and experimental verification were used to analyze its thermal performance. The difference between an S-channel and a straight channel was compared, and multi-condition simulations were carried out to explore the effects of air temperature, flow rate, and thermal conductivity of the PCMs. Furthermore, the heat releasing cut-in time during simultaneous heat storage and discharge conditions on the thermal performance and heat storage capacity was also analyzed. Increasing the hot air temperature, flow rate, and thermal conductivity of the PCMs can help shorten the heat storage time (9.3–51.2%) with varying characteristics, and it has a great impact on the heat storage capacity, which is about 26,000 KJ. Increasing the flow rate can increase the heat storage and heat release rates, with 4 m/s being the best flow rate. When the storage temperature difference is greater than the heat discharge temperature difference, turning on the synchronous storage and discharge conditions can continue to increase the liquid phase rate.
