摘要:对夏热冬冷地区某项目空调冷热负荷进行详细计算和分析,将双冷凝器水源热泵机组应用于冷却塔辅助型复合式地源热泵系统,通过灵活的机组配置及合理的运行策略解决了地源热泵系统土壤释热量和取热量的平衡问题,并详细介绍了运行策略。由于理论计算和实际运行参数存在偏差,提出土壤温度动态纠偏的理念,保证地下温度场的长期平衡,达到地源热泵系统长期高效、稳定运行的目的。

Abstract: The air conditioning cooling and heating load of a project in hot summer and cold winter zone is calculated and analyzed in detail, and the dual-condenser water-source heat pump unit is applied to the cooling tower-assisted compound ground-source heat pump system. The flexible unit configuration and reasonable operation strategy solve the problem of the balance of heat release and heat extraction from soil in the ground-source heat pump system, and the operation strategy is presented in detail. Due to the deviation between theoretical calculation and actual operation, the concept of soil temperature dynamic correction is proposed to ensure the long-term balance of the underground temperature field and achieve the purpose of long-term efficient and stable operation of the ground-source heat pump system.
Keywords: compound ground-source heat pump system; dual condenser; water-source heat pump unit; operation strategy; heat balance of soil;
