Lesi yisimo somoya somoya sokucindezela kwengcindezi yesimo emithathu, okubandakanya ukushintshwa kwengcindezi ephezulu nephansi kanye nokushintshwa kwe-voltage ephakathi. Ukushintshwa kwengcindezi yezimo ezintathu kufakwa kwipayipi eliphakeme lokucindezela kohlelo lokufaka umoya.
Ukushintshwa kwengcindezi ephansi: Lapho kuvuleka uhlelo lokuvuna umoya noma esiqandisini sephansi, ukuze kuvikeleke i-compressor kusuka kumonakalo, umjikelezo wokulawula we-compressor unqunywe ngenkani ukumisa i-compressor.
I-Mid-State switch: Lapho ingcindezi yokuvumelanisa iphakeme, cindezela umlandeli ovumelanayo ukuthi ajikeleze ngejubane elikhulu ukunciphisa umfutho wengcindezi ephezulu futhi andise umphumela wokupholisa.
Ukushintsha kwengcindezi ephezulu Lapho ingcindezi ephezulu yengcindezi ye-air conditioner iphakeme ngokungajwayelekile, ukushintshwa kwengcindezi ephezulu kuvulwa ukuze kunqunywe umjikelezo wokulawula we-compressor, kanye nohlelo lokufaka umoya luyama ukusebenza.
I-air conditioner Three-State Pressure switch inemigqa emine: ezimbili zishintsha okuphakathi kwe-voltage, ezisetshenziselwa ukulawula fan fan fan. Abanye ababili bacindezelwa okuphansi kanye nengcindezi ephezulu ndawonye ukulawula ukusebenza kokucindezela.
Njengoba kukhonjisiwe kumdwebo wesifunda: Ngemuva kokushintsha kwe-A / C kufakwa isiginali kuphaneli ye-Air conditioner, iphaneli yomoya izokukhipha isiginali ekushintsheni kwengcindezi yesikhashana (imvamisa isiginali esingesihle) Ukushintshwa kwengcindezi ephakemeyo kuthola ingcindezi ngaphakathi kwepayipi nokuthi ngabe kunengcindezi ephezulu nephansi kuvamile. Uma kujwayelekile, ukushintshwa kwangaphakathi kuzovulwa bese kuthumela isiginali ebhodini lekhompyutha yenjini. Ibhodi lekhompyutha lilawula ukudluliselwa kwe-compressor ukudonsa kanye ne-compressor allys.Kukhona futhi nocingo oluvame ukubekwa khona. Lapho i-voltage yangaphakathi ye-Medium ye-State Switch ye-Three-State ijwayelekile, ukushintshwa kuvaliwe, futhi isiginali ithunyelwa ebhodini lekhompyutha ye-Injini ukulawula i-Cooding Fan edluliselwe kudluliselwe ku-fan epholile ukudonsa.
