<p>the speed of which is proportional to the frequency of the AC it is fed, so the compressor can be run at variable speeds--eliminating compressor stop-start cycles increases efficiency. A <a href="page.php?w=microcontroller">microcontroller</a> typically monitors the temperature in the space to be cooled, and adjusts the speed of the compressor to maintain the desired temperature. The additional electronics and system hardware add cost to the equipment, but can result in substantial savings in operating costs. The first inverter air conditioners</p><p>
