The Research Of Aptitudinal Frequency Conversion Control System For Saving Electric Energy On Center Air-condition

This thesis combines the Shenzhen city hall reformation item in energy economy, give the concrete reformation implement project for central air condition frequency conversion economy energy.Center air-condition system is normally composed of refrigeration, freezing water system, cooling water system, cooling tower, terminal facility and fresh wind engine. At present, more and more transducer have been applied in pump, it can save a lot of electricity. So this thesis do the thorough research to obtain the best energy conservation effect.The study begin with the analysis of theory about central air-conditioner. We find that difference in temperature can reflect the cooling load more exactly, so it should be the basis of control. We design the control system against central air-conditioner, to realize the remote communications. Design the communication network base on RS-485. Then introduce how to design the control interface of touch panel.
