【摘要】：采用系统工程的方法优化热泵供暖系统操作,实现节能运行具有重要意义。在建立热泵供暖系统基本动态方程的基础上,给出了考虑室温控制精度和能耗节省的优化操控目标,通过联立求解方法将原微分代数方程优化问题(DAOPs)转化为非线性规划问题,然后对不同目标侧重下的动态操作优化问题进行了分析,并提出了动态调整目标函数权重的优化策略。优化计算结果表明:在室温跟踪误差最大为0.85℃的情况下系统可实现16%以上的节能效果;环境温度和电价对系统操作优化具有重要影响,根据两者的变化特征而动态调整目标函数权重可以进一步降低系统能耗4.7%左右。本研究对热泵供暖系统优化节能控制具有一定的现实意义。
[Abstract]:It is of great significance to optimize the operation of heat pump heating system and realize energy saving operation by system engineering method. On the basis of establishing the basic dynamic equation of heat pump heating system, the optimal control target considering room temperature control precision and energy saving is given. The original differential algebraic equation optimization problem (DAOPs) is transformed into a nonlinear programming problem by simultaneous solving method. Then the dynamic operation optimization problem with different objectives is analyzed. An optimization strategy is proposed to dynamically adjust the weight of the objective function. The results of optimization calculation show that the energy saving effect of the system can be more than 16% when the maximum tracking error is 0.85 鈩，
