摘要
分析比较了目前常用的几种变频控制方法的节能效果与可行性.通过定性分析与定量计算得出温差控制方法节能效果最好,其次是最小阻力控制方法,最差的是定压差控制方法.工程采用何种控制方法,应根据空调水系统的规模、负荷的组成、空调系统配置、水系统的阻力平衡、末端设备的同时使用率等具体情况加以分析判断.
The energy-saving effect and feasibility of several kinds of variable frequency circulating pump control in air conditioning system were analyzed and compared. Both qualitative analysis and numerical calculation show that the temperature difference control method has the best energy-saving effect, and the second is the minimum resistance control method, and the pressure difference control has the worst energy-saving effect. The utilization of the control method in engineering design needs a good balance and careful analysis according to the system size, composing of the load, the balance of the resistance of the water system, and the frequency of the application of the end equipment.
