Default RPM falls when a/c starts

I have civic-98 EXI. Its RPM is set around 1000. When ever i start a/c,,, RPM falls around 400. When a/c compressor stops on its timing rpm rises to normal 1000 and when compressor starts again it decreases again around 400. What would be the problem? Plz help....
