| 英文摘要: |
| With the rapid development of the variable frequency technique for speed control of alternating-current motors, this technique has found increasingly extensive applications in air-conditioning systems and has proved itself to be very effective for energy conservation, e.g. in VAV air-conditioning systems. This paper described the variable frequency control technique and the principle and application of the technique for energy conservation in air-conditioning systems. The dependence of the power consumption on the control modes of flowrate in the air-conditioning system was analyzed in detail. By means of case study it was demonstrated that the variable frequency technique can be used for the control of flowrate in the air-conditioning system and consequently achieve remarkable results for energy saving. |
