基于热力循环分析,将水-水热泵的运行特性归结为8个待定的特性参数,并以此为基础建立了利用样本数据来预测待定参数的特性参数优化预测热泵模型。阐述了参数优化预测的过程及模型的实施步骤,实例计算表明,该模型具有较好的预测精度与延伸预测能力,为能源利用系统中水-水热泵的动态性能仿真提供了一个简单实用的方法。

A characteristic parameters optimization prediction model of water-to-water was presented to analyse the operation performance of water-to-water heat pump by use of 8 undetermined characteristic parameters. The model can be used to predict the values of the characteristic parameters by means of manufacturers＇catalog data. The procedure of parameter optimization prediction and model implementation were described in detail. Both favorable prediction precision and good extend prediction capability were obtained in a specific example computation. The heat pump model developed here may present a simple and applicable simulation method for determining the dynamic performance of water-to-water heat pump in energy utilization system.
