Operation strategy of a compound ground-source heat pump system in hot summer and cold winter zone
摘要：
對夏熱冬冷地區某項目空調冷熱負荷進行詳細計算和分析，將雙冷凝器水源熱泵機組應用于冷卻塔輔助型復合式地源熱泵系統，通過靈活的機組配置及合理的運行策略解決了地源熱泵系統土壤釋熱量和取熱量的平衡問題，并詳細介紹了運行策略。由于理論計算和實際運行參數存在偏差，提出土壤溫度動態糾偏的理念，保證地下溫度場的長期平衡，達到地源熱泵系統長期高效、穩定運行的目的。
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.
