被动式太阳房冬季保温性能实验与模拟——以阿瓦提农场改造项目为例

Experiment and Simulation of Thermal Insulation Capacity in Winter of Passive Solar Building: A sample from the retrofitting project in Awat Farm

由于新疆库尔勒地区气候特殊,阿瓦提农场内的农户自建房节能改造形式多选择附加阳光间式太阳房。被动式太阳房节能改造项目在该地区实施以来,基于该地区特定的气候,针对被动式太阳房的冬季保温性能鲜有研究。现利用被动式太阳房热特性评价指标和能耗模拟对其进行评价。通过实验和模拟,发现改造后的建筑保温能力大幅提升,冬季采暖能耗大幅降低,满足新疆严寒及寒冷地区居住建筑65%节能标准,为被动式太阳房在新疆地区的推广提供了理论依据。

Sunshine rooms attached to self-built energy-saving houses are mostly selected by the peasant household living in Awat Farm due to the special climate in Korla region of Xinjiang. Very few researches on heat-insulating property of passive solar house in winter have been made since the reconstruction project of energy-saving houses implemented in this region was put into effect. The heat-insulating property of passive solar house is evaluated by using thermal evaluation index and energy consumption simulation. Through experiment and simulation,it is confirmed that the thermal insulation capacity of the building has been greatly improved and the energy consumption of heating greatly reduced in winter by reconstructing the building,thus meeting the energy-saving standard of 65%for residential buildings in cold regions of Xinjiang. It provides a theoretical basis for popularization of passive solar house in Xinjiang.
