安吉夯土房室内热环境现场测试研究

对夯土建筑的隔热、保温性能进行科学评价可为其维持建筑内部热环境的优越性提供有效证明。以浙江安吉生态旅馆为测试研究对象,设置测试点33个,并于2007年1月27日～2月2日利用数据采集仪、温度传感器等设备测量并记录生态旅馆室内、室外的空气温度以及围护结构的表面温度,选取其中一段时间的数据进行比较和分析,得知:在实地测试的1月份,安吉当地昼夜温差较大,在生态旅馆未采用特别的保温措施和设备的前提下,其室内温度波动不大,全天温度变化幅度非常小,说明夯土建筑墙体具有显著的保温、隔热性能,且热稳定性显著,能够保证建筑优良的室内热环境。

Research on Site Test of Thermal Environment of Rammed Earth Construction in Anji County

The scientific evaluation on heat insulation and preservation of rammed earth construction can provide an effective proof for its superiority in preserving the thermal environment of the construction.By taking eco-hotels in Zhejiang Anji County as research objects,33 test points have been set.The indoor and outdoor air temperature of eco-hotels and the surface temperature of building envelopes had been recorded by using data logger,temperature transmitter and other equipments from January 27 to February 2 in 2007.Then,the data of a period had been selected for comparison and analysis and the results had been obtained as follows.In January when the temperature difference between day and night in Anji was not large,if without particular thermal insulation measures and equipments,the indoor temperature of eco-hotels fluctuated very little,showing that rammed earth construction had obvious capacity for heat preservation and insulation,that its heat stability was evident and that it could ensure excellent indoor thermal environment.
