摘要
冷热负荷的平衡是影响地埋管地源热泵系统寿命和运行效率的重要因素。针对用户侧冬季热负荷大于夏季冷负荷的某住宅小区,对地源热泵机房进行改造,增加过渡季热泵系统直接供冷能力以提高土壤侧的蓄热量,使冷热负荷不平衡率在允许范围内,延长地埋管地源热泵系统寿命,保持系统高效运行。
The balance of cooling and heating load is an important factor affecting the life and operating efficiency of ground source heat pump system. For a residential area where the user side winter heat load is greater than the summer cooling load,the ground source heat pump room is modified to increase the direct cooling capacity of the transition season heat pump system to increase the heat storage capacity on the soil side,so that the thermal and thermal load unbalance rate is within the allowable range. Internally,extend the life of the ground source heat pump system and keep the system running efficiently.
