Lena iswishi yomfutho we-air conditioner enezimo ezintathu, ehlanganisa ukushintshwa kwengcindezi ephezulu nephansi kanye neswitch yamandla aphakathi nendawo. Ukushintsha kokucindezela kwezifunda ezintathu kufakwe epayipini lokucindezela okuphezulu kwesistimu ye-air-conditioning.
Iswishi yokucindezela okuphansi: Uma isistimu ye-air-conditioning ivuza noma isiqandisi siphansi, ukuze kuvikelwe i-compressor emonakalweni, umjikelezo wokulawula we-compressor unqanyulwa ngenkani ukuze kumiswe i-compressor.
Iswishi yesifunda esimaphakathi: Uma ingcindezi yokujiya iphezulu, phoqa ifeni ejikisayo ukuthi ijikelezise ngesivinini esiphezulu ukuze unciphise ukucindezela okuphezulu futhi ukwandise umphumela wokupholisa.
Ukushintsha kwengcindezi ephezulu: Ukuze uvimbele ukucindezela kwesistimu ukuthi kungabi phezulu kakhulu, okubangela ukuthi uhlelo luqhume, i-compressor iyaphoqeleka ukuthi iyeke ukusebenza. Lapho umfutho we-high-pressure we-air conditioner uphezulu ngokungavamile, inkinobho yokucindezela okuphezulu iyavulwa ukuze kunqandwe umjikelezo wokulawula we-compressor, futhi uhlelo lwe-air-conditioning luyayeka ukusebenza.
I-air conditioner ye-state-three pressure switch inemigqa emine: emibili ama-voltage aphakathi nendawo, asetshenziselwa ukulawula isiphephetha-moya esishisayo. Okunye okubili ukucindezela okuphansi nokucindezela okuphezulu ndawonye ukulawula ukusebenza kokucindezela.
Njengoba kubonisiwe kumdwebo wesifunda: ngemva kokuba inkinobho ye-A/C ifake isignali kuphaneli ye-air conditioner, iphaneli ye-air conditioner izokhipha isignali ku-switch ye-ternary pressure (imvamisa iyisignali engalungile),Iswishi ye-ternary pressure ithola ingcindezi ngaphakathi. ipayipi nokuthi umfutho ophezulu nophansi ujwayelekile yini. Uma kujwayelekile, iswishi yangaphakathi izovulwa bese ithumela isignali ebhodini lekhompyutha yenjini. Ibhodi lekhompiyutha lilawula i-compressor relay ukuze idonse futhi i-compressor isebenze.Kukhona nocingo oluvame ukumiswa. Lapho i-voltage emaphakathi yangaphakathi yeswishi yezifunda ezintathu ivamile, iswishi iyavalwa, futhi isignali ithunyelwa ebhodini lekhompyutha yenjini ukuze kulawuleke ukupholisa kwefeni okudluliswayo ukuze idonse.
