Isixhobo esisetyenziselwa ukulawulwa kwe-air conditioning ekude, isilawuli esikude somoya senziwa ngokuyinhloko kwibhodi yesekethe edibeneyo kunye namaqhosha asetyenziselwa ukuvelisa imiyalezo eyahlukeneyo.I-microprocessor chip eyenza i-remote control signal, i-crystal oscillator, i-amplification transistor, i-infrared light-emitting diode, kunye ne-keyboard matrix yenza uninzi lolawulo olude.
