Idivayisi esetshenziselwa isilawuli se-air conditioning esikude, isilawuli esikude se-air conditioning senziwa ngokuyinhloko ngebhodi lesifunda elihlanganisiwe nezinkinobho ezisetshenziselwa ukukhiqiza imilayezo ehlukahlukene.I-microprocessor chip ekhiqiza isignali yesilawuli kude, i-crystal oscillator, i-amplification transistor, i-infrared light-emitting diode, kanye ne-keyboard matrix yenza iningi lesilawuli kude.
