| Summary: | 碩士 === 逢甲大學 === 電機工程所 === 92 === In order to control the temperature in the room within a specfic area, the traditional control way in the air conditional system makes the compressor from start to stop frequently. Thanks to the progress of power electronic techniques, the converter has made remarkable progress in the realiability, function and price. So, the idea which the inverter joins in the air conditional system is raised. The focal point of this thesis uses the fuzzy control theorem as a control tool, and the frequency as a principle of controlling speed, and then design the air conditional driver. This driver can change the speed for different load as well as adjust the compressor at any time. Certainly, it keeps the temperature of the air conditioning suitable human beings’ comfort and meanwhile reduce the air conditional load to achieve an objective of lowering the power load.
