【摘要】：以溫度和相對濕度為驅動勢建立吸濕性墻體熱濕耦合遷移數(shù)學模型,并通過權威案例驗證模型。根據(jù)霉菌滋生條件,建立了基于瞬態(tài)溫濕度及其持續(xù)時間的墻體內(nèi)霉菌滋生風險評價方法。以紅磚墻體為例,分析太陽輻射、室內(nèi)空氣溫濕度對墻體內(nèi)霉菌滋生風險的影響,并研究了我國南方各地墻體霉菌滋生風險。結果表明:太陽輻射越弱墻體內(nèi)霉菌滋生風險越大,室內(nèi)相對濕度升高使墻體內(nèi)側霉菌滋生風險快速增長,室內(nèi)溫度升高使墻體內(nèi)、外側霉菌滋生風險分別升高、降低;我國南方絕大部分地區(qū)墻體外側存在霉菌滋生風險,總體上呈現(xiàn)東部比西部高、南部比北部高的趨勢。
[Abstract]:Taking temperature and relative humidity as driving force, the mathematical model of thermal-moisture coupling migration of hygroscopic wall is established, and the model is verified by an authoritative case. According to the breeding conditions of mold, the risk assessment method of mold breeding in walls based on transient temperature and humidity and its duration was established. Taking red brick wall as an example, this paper analyzes the influence of solar radiation and indoor air temperature and humidity on the risk of mold breeding in the wall, and studies the risk of mold breeding in the wall in southern China. The results showed that the weaker the solar radiation, the greater the risk of mold breeding, the higher the indoor relative humidity, the higher the risk of mold breeding, and the higher the indoor temperature, the higher the risk of mildew breeding inside and outside the wall, respectively. There is a risk of mold breeding on the outside of the wall in most parts of southern China, which is higher in the east than in the west and higher in the south than in the north.
