With the residents of (Wenchuan) earthquake-stricken area as the object for study, the long-term monitor and the massive questionnaire survey and the statistical regression analysis with the data and the questionnaires, the paper has obtained the indoor and outdoor thermal environment characteristics in each time section of Dongping country, Xiaoyudong town, Pengzhou city, and the key time of improving the local indoor thermal environment is in winter. The paper also obtains the indoor acceptable temperature ranges under 80% satisfaction rates in the appraisal model of PMV and TSV, and finds that the indoor acceptable temperature ranges in the appraisal model of TSV displace downward much compared to that of in the appraisal model of PMV. Because of the results are remarkable different in the appraisal model of PMV and TSV, this paper revises the values of PMV with the expectation factor (0.7) that is suitable to China suggested by Professor Fanger, and finds it could not revise the values of PMV well in this region. According to mathematics principle the paper proposes a new revision model, the PMV linear revision model, and through confirmations, this model has good revision effect to the PMV value. Through the test of indoor and outdoor thermal environment of reconstructs, the paper carries on the confirmation once more to the PMV linear revision model, the result explains the feasibility and reliability of this revision method proposed by this paper.
