Design parameter determination method and application of untreated sewage-source heat pump systems
摘要：
原生污水源热泵系统设计过程影响因素较多，在末端用户需求负荷和供回水温度参数确定后，对系统设计的主要影响参数包括污水的进出水温度和热泵机组蒸发器的进出水温度，上述温度参数对系统内热泵、污水泵、中介水泵、污水换热器设备选型及运行工况均有影响。设备选型及运行工况变化直接决定该类系统的投资和运行费用。以年总费用为目标函数，利用复合形法对上述参数的确定进行了优化，结合算例，说明了该方法的应用。
Abstract：
There are many influencing factors in designing an untreated sewage-source heat pump system. When determining the user’s demand load and the temperature parameters of the supply and return water, the main influencing parameters include the inlet and outlet temperatures of the system and the evaporator of the heat pump unit. The above temperature parameters affect the selection and operation conditions of the equipment including heat pumps, sewage pumps, intermediate pumps and sewage heat exchangers. The investment and operating cost of the system are directly affected by the selection and operation parameters of the equipment. Taking annual total cost as the objective function, applies a complex method to optimize the determination of the above parameters and illustrates its application by an example.
