摘要
通过建立螺杆式制冷压缩机模型,并与冷凝器、蒸发器模型耦合,联合求解得到了地下水源热泵机组的能耗计算模型。在压缩机部分负荷效率的基础上提出了部分负荷制冷/热量效率和制冷/热量与耗功率的不平衡系数,以更好的模拟热泵组部分负荷工况下的实际制冷/热量变化情况。将该模型应用于某地下水源热泵机组,计算结果表明该模型具有较高的精度。
Through the establishment of screw refrigeration compressor model and associating with condenser model and evaporator model, energy consumption calculation model of GWHP units has been obtained. On the basis of the compressor part load efficiency, part load efficiency of cooling and heating capacity and unbalance coefficient between cooling and heating capacity with energy consumption have been put forward to simulate changes in part load condition. The model was applied to a GWHP units and the results show that the model has high accuracy.
