Operation strategy of a compound ground-source heat pump system in hot summer and cold winter zone

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.
