摘要
以夏热冬冷地区某典型住宅为例,通过分析全年动态负荷、土壤取放热量、土壤温度变化等,探究土壤源热泵在夏热冬冷地区住宅建筑中的适用性。模拟计算结果表明,冬夏季的累计负荷差异较大,全年累计冷负荷约为热负荷的2.79倍,夏季向土壤累计放热量约为冬季累计取热量的3.74倍。夏热冬冷地区住宅建筑中不适宜直接单独应用土壤源热泵系统,必须采取辅助供冷、散热措施,保证全年取放热量平衡,扩大土壤源热泵系统的使用范围。
Taking a residential building in hot summer and cold winter area as an example, analysis on applicability of ground source heat pump in residences of hot summer and cold winter region was carried out by annual dynamic load, soil heat transfer, soil temperature change. Simulation results show that the cumulative load difference between winter and summer is large. The accumulated cold load in the whole year is about 2.79 times of the heat load. The cumulative heat release to the soil in summer is about 3.74 times the cumulative heat taken in winter. It is not suitable to directly apply the ground source heat pump system in residential buildings in hot summer and cold winter region. It is necessary to adopt auxiliary cooling and heat dissipation measures to ensure the heat balance of the whole year. By this way, the use range of the ground source heat pump system could be expanded.
