| 为优化装配式异质复合墙体日光温室的建筑参数，利用TRNSYS（Transient system simulation program）建立温室模型，采用连续阴天和连续晴天的实测数据验证模型，利用该模型分析温室脊高、北墙高度、后屋面水平投影宽度的改变对室内温度、北墙温度和建造成本的影响。结果表明：室内温度、北墙温度和总建造成本随脊高增大而增加，当脊高>5.3 m时，室内平均温度和北墙平均温度的增幅明显降低，但建造成本仍增加；室内温度、北墙温度和总建造成本随北墙高度增大而增加，北墙高度为3.7 m时室内温度和北墙温度达到较好效果，北墙高度继续增大，对温度的提升效果并不明显；后屋面水平投影宽度为1.8 m时，温室后屋面仰角为46°，采光屋面角为27°，可满足温室内采光要求。综上，温室脊高为5.3 m，北墙高度为3.7 m，后屋面水平投影宽度为1.8 m时，可达到室内热性能和建造成本的最佳平衡，此时温室总建造成本为22.15万元，每平方米建造成本约230元。 |

| Abstract: |
| In order to optimize the construction parameters of the solar greenhouse with assembled heterogeneous composite wall， a greenhouse model was established using TRNSYS （Transient system simulation program）， and the measured data of consecutive cloudy and consecutive sunny days were used to validate the model. The model was utilized to analyze the effects of changes in the greenhouse ridge height， height of the north wall and horizontal projection width of the rear roof on the indoor temperature， north wall temperature， north wall temperature and construction cost. The results showed that： The indoor temperature， north wall temperature and total construction cost increased with increasing ridge height. When the ridge height was >5.3 m， the increase in mean indoor temperature and mean north wall temperature decreased significantly， while the construction cost still increased； The indoor temperature， north wall temperature and total construction cost increased with increasing height of the north wall， and the better results for indoor temperature and north wall temperature were achieved at the height of the north wall of 3.7 m. Continuing to increase the height of the north wall did not have a significant effect on the temperature enhancement； When the horizontal projection width of the rear roof was 1.8 m， the elevation angle of the rear roof of the greenhouse was 46°， and the angle of the light roof is 27°， which met the lighting requirements in the greenhouse. In summary， the best balance between the indoor thermal performance and construction cost can be achieved when the ridge height of the greenhouse is 5.3 m， the height of the north wall is 3.7 m， and the horizontal projection width of the rear roof is 1.8 m. At this point， the total construction cost of the greenhouse is 221.5 thousand， and the construction cost of each square meter is about 230 yuan. |
