Study on the design and operation optimization of intermittent solar heating building
On the basis of the indoor temperature and heat load characteristics of passive solar heating house, it is found that: the thermal environment can not fully satisfy the thermal comfort requirements during the heating period, and it needs to combine with the active heating system. However, the passive solar house indoor temperature is higher than setting temperature in the part time of heating period. Therefore, the active system should apply intermittent running mode to meet the requirements of the indoor temperature conditions. The selection principle of the intermittent heating floor structure design and operation parameters were obtained and the room temperature change characteristics under the adjustment of the coupled intermittent heating and passive solar energy technology analyzed. The results show that the average room temperature can keep 18℃ or so, and the fluctuations remained between 2～3℃. The coupled regulation technology reduces the heating time and avoids the indoor overheating caused by continuous heating at the same time, and plays a positive role in heating energy saving and indoor thermal comfort.
