中文摘要：

通过对室内氡的来源及氡浓度平衡的分析，建立了室内氡浓度的估算模型。在此基础上，建立了通风降氡能耗与室内氡浓度之间的计算模型，对空调房间内冬夏两季通风降氡能耗和通风换气率进行模拟。通过通风换气率整合两个模型，模拟得出室内通风降氡能耗与室内氡浓度二者之间的关系。以湖南省衡阳市住房进行模拟分析，分析结果表明，室内通风降氡能耗随着室内氡浓度降呈指数类增长，当室内氡浓度值较低时，空调通风降氡能耗要高于高浓度时降低相同氡浓度时所需能耗。

英文摘要：

By the source of indoor radon and diffusion analysis, the calculation model of indoor radon concentration was gotten. Based on this, the calculation model of energy consumption and indoor radon concentration was formed, then the relation between energy consumption of reducing indoor radon ventilation and ventilation rates in winter and summer was simulated. Integrating the two models with ventilation rate, then the relationship between energy consumption and indoor radon concentration was inferred, and was analyzed in Hengyang, Hunan province. The results show that the to decrease indoor will exponential increased with the reduction of indoor radon concentration. When the indoor radon concentration is low, the energy consumption is higher than in a higher radon concentration with the same radon concentration reduction.
