水源热泵系统温度控制研究

Study of Temperature Control in Water Source Heat Pump System

现在的水源热泵采用的控制系统控制精度不高,不能很好地跟踪系统负荷而运行,特别是在温度的控制上还不具备自适应的能力,因而很难满足舒适性和高效节能的要求。针对这些问题,将模糊控制技术引入地源热泵的控制中,并和传统PID控制算法比较。通过Matal-ab仿真,具体比较模糊控制和PID控制在水源热泵系统控制中的性能,然后做出总结。

If the temperature in the water source heat pump system is not controlled accurately, its load and running can not be traced. The system lost the adaptive ability of the temperature control, it is difficult to make the system meet the requirement of the comfort and energy efficiency. This paper introduces the fuzzy control technology into the control of water source heat pump. By Ma- talan simulation, the pertormancc of the fuzzy control in the water source heat pump system is compared with that of PID control and then the conclusion is come to.
