双管路燃气热泵(GEHP)系统仿真与实验研究

Simulation and Experiment on Double Pipelines Gas Engine-driven Heat Pump System

通过建立双管路燃气热泵(GEHP)系统的数学模型,研究了制热工况下系统的环境特性及部分负荷特性。模拟结果表明,双管路燃气热泵的一次能源利用率(PER)随转速升高而降低,即具有良好的部分负荷特性。对双管路GEHP系统的运行特性进行了实验研究,通过实验结果与计算结果的对比,验证了仿真模型的合理性。

A numerical model of a gas-driven heat pump （GEHP） system was established. The environmental characteristics and partial load characteristics of the system under the heating condition were analyzed with the present model. The numerical results show that the PER （Primary Engine Ratio） decreases with the increase of the engine speed and thus the system has good partial load characteristics. The experiment on the GEHP system with double pipelines was conducted and the results show that the experimental data are consistent with the predictions.
