摘要
北方某些地区由于冷热负荷的不平衡性,单一的土壤源热泵系统受到限制。太阳能辅助土壤源热泵系统是一种有效利用可再生能源的系统形式。本文对天津地区太阳能辐射情况、建筑全年逐时冷热负荷量及复合热泵系统的制热机组效率进行研究,分析在天津地区太阳能-土壤源复合热泵系统的节能性。
Because of the imbalance in cold and hot load in northern China, the application of single soil source heat pump system is limited. The solar energy assisted heat pump system is a kind of effective form to take advantage of renewable energy source. The solar radiation, building all-year hourly cooling and heat load and the unit efficiency of composite heat pump were discussed, and the performance of solar energy-ground source combined heat pump system in Tianjin region was analyzed.
