能量回收通风（ERV）是降低建筑暖通空调系统能源需求的重要工具，通常约占建筑总能耗的40%。许多ERV设计都可以在市场上买到。然而，人们越来越需要在建筑中进行更高效的能源回收，以进一步减少碳足迹。在这项工作中，我们研究了一种新型的旋转式能量回收通风机，该通风机与相变材料（PCM）相结合，可以吸收进入空气中的显热和潜热，用于初始温度和湿度控制。它可以利用相变过程中相变材料的大量熔化潜热来增强吸热/放热，从而进一步改善新风的温度调节。 这种设计的特点是能量轮由铝蜂窝材料和生物基PCM宏观封装在轮的圆柱形辐条中组成。通过使用ANSYS Fluent进行传热和计算流体动力学模拟，确定了PCM嵌入轮的最佳几何结构，以实现进入的热空气的最大温度降低。根据优化设计制造了PCM集成能量回收呼吸机原型。对制造的样机进行了测试，以证明其热湿回收性能。由于PCM的存在，预计拟建ERV系统的热回收率将显著提高，以实现高效建筑节能。引用:2020年虚拟会议论文

Energy recovery ventilation (ERV) is an important tool to reduce the energy demands of building HVAC systems, which typically account for approximately 40 percent of overall building energy consumption. Many ERV designs are commercially available. However, there is an increasing need for more efficient energy recovery in buildings to further reduce carbon footprints. In this work, we investigated a novel rotary energy recovery ventilator coupled with phase change material (PCM), which can absorb both sensible and latent heat from the incoming air for the initial temperature and moisture control. It can utilize the large amount of latent heat of fusion of PCM during its phase change process to enhance the heat absorption/releasing to further improve the temperature regulation of the fresh air. This design features an energy wheel comprising aluminum honeycomb material, and bio-based PCM macroencapsulated in cylindrical spokes of the wheel. Through the heat transfer and computational fluid dynamics simulations using ANSYS Fluent, the optimal geometry of the PCM embedded wheel was determined to achieve the maximum temperature reduction for the incoming warm air. The proposed PCM integrated energy recovery ventilator prototype was manufactured based on the optimal designs. The fabricated prototype was tested to demonstrate its performance on the heat and moisture recovery. The heat recovery of the proposed ERV system is expected to be remarkably enhanced due to the presence of PCM for efficient building energy savings.
