德国被动房在我国夏热冬冷地区的试点和推广已陆续展开,但具体运行效果尚未给出明确结论。本文通过对夏热冬冷地区某实际运行的德国被动房冬季运行情况进行实测,分析了被动房在机械通风系统不开启,仅凭借其良好的保温隔热性和气密性条件下的室温响应情况。结果表明,在室内无人且无任何辅助供热措施条件下,被动房在寒潮期间的室温能稳定在18℃左右;在室内有人长期居住条件下,测试期间室内温度高于18℃以上的时间从无人状态的55.1%提高到了100%;冬季可进行短时间开窗通风改善室内空气质量,短时间开窗对室温影响不大。
The passive rooms in Germany in China hot summer and cold winter pilot and promotion have been carried out one after another, but the specific operating results have not yet made a clear conclusion. In this paper, the practical operation of the passive winter house in Germany in the hot summer and cold winter area is measured. The analysis of the room temperature response of the passive house without mechanical ventilation system is based on its good thermal insulation and air tightness . The results show that under the conditions of no indoor heating and no auxiliary heating measures, the room temperature of the passive house can be stabilized at about 18 ℃ during the cold wave period. Under the long-term living conditions in the room, the indoor temperature during the test period is higher than 18 ℃ From 55.1% unmanned state increased to 100%; winter can be a short time window ventilation to improve indoor air quality, a short window has little effect on room temperature.
