污水源热泵系统的逐时需水量预测及工程设计

Forecasting Hourly Sewage Quantity of Heat Pump System and Engineering Design

以武汉具体工程为例,通过对建筑物室外全年逐时干球温度和逐时负荷的计算,选取合适的污水源热泵机组,建立描述污水源热泵机组的工程应用模型,通过相对误差检验得知此模型具有较高的精度。预测逐时污水流量,提出在实际工程设计中应该注意的事项,在污水量不足的状况下提出欠流量的解决方案。

This paper takes an engineering project in Wuhan as an example, calculating the annual hourly dry-bulb temperature and hourly load of building outdoor firstly, then selecting the appropriate sewage source heat pump, the application model is established to describe the sewage source heat pump＇s performance. By relative error testing, the model has high accuracy. Forecasting hourly sewage quantity, putting forward precautions in the actual project, solutions are proposed in the condition of the limited sewage flow rate.
