This paper presents a phase change material enhanced ventilated window (PCMVW) for both ventilation pre-cooling and pre-heating purposes. The PCM heat exchanger is used as a heat sink in the ventilation pre-cooling application and thermal energy storage in the ventilation pre-heating application. The paper presents a night cooling experiment and a solar energy storage experiment in order to investigate the thermal and energy performance of the PCMVW, and a ventilated window (VW) self-cooling experiment for overheating protection. Two VWs were tested in the façade lab in Aalborg (Denmark), and one of them is with PCM heat exchanger. The two windows were equipped with the same outdoor conditions and ventilation airflow. The experimental results show that for ventilation pre-cooling application with the PCM heat exchanger, the room inlet air temperature is by average 1.4 °C lower for 7 h during the daytime compared to the normal VW. The average energy saving is 0.7 MJ/day compared to a normal VW. The PCMVW cooling capacity is limited without advanced blinds control and system operation control. In ventilation pre-heating application, the PCM increases the inlet air temperature of the VW by 2.0 °C for 12 h. The average energy saving is 1.6 MJ/day compared to a normal VW. Buildings in a climate with high outdoor air temperature differences can benefit more from the PCMVW in ventilation pre-cooling application, but the pre-cooling ability is limited. While in ventilation pre-heating application the buildings in the climate with higher solar radiation levels has a higher energy performance. Moreover, the VW self-cooling application is more effective to decrease the overheating of the room than VW without self-cooling.

本文介绍了一种用于通风预冷和预热目的的相变材料增强型通风窗（PCMVW）。PCM热交换器在通风预冷应用中用作散热器，在通风预热应用中用作热能存储。为了研究PCMVW的热和能量性能，本文提出了夜间降温实验和太阳能存储实验，以及用于过热保护的通风窗（VW）自冷却实验。在丹麦奥尔堡的立面实验室对两台大众汽车进行了测试，其中一台采用PCM热交换器。两个窗户都配备了相同的室外条件和通风气流。实验结果表明，对于使用PCM热交换器进行通风预冷的应用，与正常的大众汽车相比，白天的房间进气温度在7天内平均降低1.4°C。与普通大众车相比，平均节能量为每天0.7 MJ。如果没有高级百叶窗控制和系统操作控制，则PCMVW的冷却能力将受到限制。在通风预热应用中，PCM将大众汽车的进气温度升高2.0°C，持续12 h。与普通大众车相比，平均节能量为1.6 MJ /天。在室外空气温度差异较大的气候中，建筑物在通风预冷应用中可以从PCMVW中受益，但预冷能力有限。在通风预热应用中，建筑物在具有较高太阳辐射水平的气候中具有较高的能源性能。此外，
