Abstract

The indoor thermal environment of the passive building was investigated in Harbin in the severe cold area of China. The results showed that the average indoor temperature of the passive building is 25.5℃, which exceeds the upper comfort limit of 24℃. This study aims to optimize the indoor thermal environment of the passive building. We established the coupled heat transfer model of composite system, conducted orthogonal experiments to analyze the influence of the composite system parameters on the indoor thermal environment, and determined the optimal combination plan. PMV was used as the evaluation index, and the vertical and condensation temperature difference were used as the verification index. The results showed that the best combination of winter conditions was that the water supply temperature was 28℃, supply air temperature was 18℃, supply air speed was 0.35m/s. While in summer, the best combination conditions was as follows: the water supply temperature was 20℃, supply air temperature was 25℃, supply air speed was 0.5m/s.
