内蒙古西部超低能耗草原民居多能互补供暖系统集成配制

内蒙古西部草原民居冬季取暖以传统火炕和土暖气为主,由于供暖效果较差,无法满足居民热舒适需求。为改善供暖效果,充分利用太阳能、风能等可再生能源,通过实地调研,统计得出内蒙古西部典型草原民居最冷月室内外温度,利用数值模拟方法建立太阳能、风能等多能互补的内蒙古西部草原民居供热模型,并进行模拟验证。结果表明:多能互补供暖方式下客厅和主次卧的最冷月日平均温度均值分别提高7. 0℃、6. 2℃和7. 5℃,室内温度和热稳定性显著提高,热舒适性较好。研究结果为草原民居设计建造中充分利用太阳能、风能资源,构建多能互补供暖方式,提高室内温度和热舒适性提供了理论依据。

Integrated Preparation of Multi-energy Complementary Heating System for Ultra-low Energy Grassland Folk Houses in Western Inner Mongolia

In the western grassland of Inner Mongolia, traditional fire Kang and old water heating system are mainly used for heating the grassland folk houses in winter. Due to poor heating effect, the thermal comfort needs of residents cannot be met. In order to improve the heating effect and make full use of renewable energy such as solar energy and wind energy, the indoor and outdoor temperatures of the coldest month of the typical grassland folk houses in the western Inner Mongolia was obtained through field investigation and statistics. Then a multi-energy complementary heating model, which can utilize solar energy, wind energy and so on was established by using the numerical simulation method. Finally, the residential heating model was simulated and verified. The results show that the average temperature of the coldest day of the living room, master bedroom and second bedroom in the multi-energy complementary heating model is increased by 7.0 °C, 6.2 °C and 7.5 °C respectively, the indoor temperature and thermal stability are significantly improved, and the thermal comfort is better. The results provide a theoretical basis for the design and construction of grassland folk houses to make full use of solar energy and wind energy resources, to build multi-energy complementary heating methods, and to improve indoor temperature and thermal comfort.
