摘要
夏热冬冷地区的农村住宅需要满足建筑保温隔热、地面防潮的要求。现有调查表明,农村住宅地面存在潮湿问题,易发生季节性的地面凝结泛潮现象,影响室内居住品质和居民的身体健康,但另一方面,农村住宅地面温度也是夏季室内被动降温的有利因素,因此需要对地面防潮措施进行优化。本文针对常用的通风架空地面进行优化,提出架空层季节性通风控制,并以重庆农村住宅为例,进行模拟分析。结果显示:优化架空地面不仅能够满足地面防潮需要,而且能够提高地面热工性能,对冬季和夏季的室内热环境和建筑节能产生有利影响:夏季室内地面平均温度可降低0.5℃,冬季底层室内平均温度可提高1℃;在室内采暖空调状态,可减少夏季地面热流19%、冬季地面热流80%。
Rural houses in hot summer and cold winter zone need to meet the requirements of building thermal insulation and ground damp-proofing. Previous research has shown that humidity has become a problem on the ground of rural houses, and seasonal condensation is prone to occur, which affects the indoor living quality and health of residents. But on the other hand, the ground temperature is also a favorable factor for passive cooling in summer. Therefore, it is necessary to optimize the ground damp-proofing measures. In this paper, the ground damp-proofing of ventilated overhead ground are optimized, and the simulation analysis is carried out by taking Chongqing’s rural housing as an example. The results show that optimizing the overhead ground can not only meet the needs of ground damp-proofing, but also improve the thermal performance of the ground, which has a positive impact on the indoor thermal environment and building energy conservation. The average indoor floor temperature in summer can be reduced by 0.5 ℃, and the average indoor air temperature in the ground floor room can be increased by 1 ℃ in winter. In the state of heating and cooling by air conditioner, the heat flux on the ground can be reduced by 19% in summer and 80% in winter.
