Ukubuka Konke Kokuphathwa Kokushisa Kwezitini (Umoya Opholile Wezimoto)

Uhlelo lokupholisa umoya lubalulekile ekuphathweni kokushisa kwezimoto. Bobabili abashayeli nabagibeli bafisa induduzo ezimotweni zabo. Umsebenzi oyinhloko wokupholisa umoya wezimoto ukulawula izinga lokushisa, umswakama, kanye nokuhamba komoya ngaphakathi kwegumbi labagibeli ukuze kudalwe indawo yokushayela nokugibela ekhululekile. Isimiso esiyinhloko sokupholisa umoya wezimoto sisekelwe esimisweni se-thermophysical sokuhwamuka komoya okumunca ukushisa kanye nokujiya okukhulula ukushisa, ngaleyo ndlela kuphole noma kufudumale ikamelo. Lapho izinga lokushisa langaphandle liphansi, liletha umoya ofudumele ekhabini, okwenza umshayeli nabagibeli bazizwe bengabanda kakhulu; lapho izinga lokushisa langaphandle liphezulu, liletha umoya opholile ekhabini, okwenza umshayeli nabagibeli bazizwe bepholile nakakhulu. Ngakho-ke, ukupholisa umoya wezimoto kudlala indima ebalulekile ekupholiseni umoya ekhabini kanye nenduduzo yabagibeli. 

1.1 Uhlelo Lomoya Wezimoto Olusebenzisa Uphethiloli Lwendabuko kanye Nesimiso Sokusebenza Izinhlelo zomoya wezimoto ezisebenzisa uphethiloli zendabuko zakhiwe kakhulu yizingxenye ezine: i-evaporator, i-condenser, i-compressor, kanye ne-expansion valve. I-air conditioner yezimoto ihlanganisa uhlelo lokuqandisa, uhlelo lokufudumeza, kanye nohlelo lokungenisa umoya; lezi zinhlelo ezintathu zakha uhlelo lomoya wezimoto oluphelele. Isimiso sokuqandisa ezimotweni ezisebenzisa uphethiloli zendabuko sihilela izinyathelo ezine: ukucindezela, ukujiya, ukunwebeka, kanye nokuhwamuka. Isimiso sokufudumala sezimoto ezisebenzisa uphethiloli zendabuko sisebenzisa ukushisa okungcolile okuvela enjinini ukuze kufudumale indawo yabagibeli. Okokuqala, i-coolant eshisayo kakhulu evela ejazini lamanzi okupholisa lenjini ingena endaweni ye-heater. Ifeni ivuthela umoya opholile kuyo yonke indawo ye-heater, bese umoya ofudumele uvuthelwa endaweni yabagibeli ukuze kufudumale noma kuncibilikise amafasitela. I-coolant bese ibuyela enjinini ngemva kokushiya i-heater, iqede umjikelezo owodwa.

1.2 Uhlelo Olusha Lokupholisa Umoya Wezimoto Zamandla kanye Nesimiso Sokusebenza

Imodi yokushisa yezimoto ezintsha zamandla ihluke kakhulu kweyezimoto zendabuko ezisebenzisa uphethiloli. Izimoto zendabuko ezisebenzisa uphethiloli zisebenzisa ukushisa okulahliwe kwenjini okudluliselwe egumbini labagibeli nge-coolant ukuze kukhushulwe izinga lokushisa. Kodwa-ke, izimoto ezintsha zamandla azinayo injini, ngakho-ke ayikho inqubo yokushisa eqhutshwa yinjini. Ngakho-ke, izimoto ezintsha zamandla zisebenzisa ezinye izindlela zokushisa. Izindlela eziningana zokushisa umoya opholile wezimoto ezintsha zamandla zichazwe ngezansi. 

1) Ukushisa kwe-Thermistor ye-Positive Temperature Coefficient (PTC): Ingxenye eyinhloko ye-PTC yi-thermistor, efudunyezwa ngocingo lokushisa, iguqula ngqo amandla kagesi abe amandla okushisa. Izinhlelo zokushisa ezipholile emoyeni ze-PTC (Potentially Transmitted Central) zithatha indawo ye-heater yendabuko ezimotweni ezisebenzisa uphethiloli nge-heater ye-PTC. Ifeni idonsa umoya wangaphandle nge-heater ye-PTC, iyifudumeze, bese iletha umoya ofudumele egumbini labagibeli. Ngenxa yokuthi idla ugesi ngqo, ukusetshenziswa kwamandla kwezimoto ezintsha zamandla kuphezulu kakhulu uma i-heater ivuliwe.

 

2) Isifudumezi samanzi se-PTCUkushisa: NjengokuthiIsifudumezi somoya se-PTCizinhlelo, izinhlelo ze-PTC ezipholiswe ngamanzi zikhiqiza ukushisa ngokusebenzisa ugesi. Kodwa-ke, uhlelo olupholiswe ngamanzi luqala ngokushisa i-coolant ngeIsifudumezi se-PTCNgemva kokuba i-coolant isishisiwe kufika ezingeni lokushisa elithile, iphonswa ngaphakathi kwe-heater core, lapho ishintshanisa khona ukushisa nomoya ozungezile. Ifeni ibe isiletha umoya oshisiwe egumbini labagibeli ukuze kushiswe izihlalo. I-coolant bese ishiswa futhi yi-PTC heater, bese umjikelezo uphinda. Lolu hlelo lokushisa luthembeke kakhulu futhi luphephile kunezinhlelo ze-PTC ezipholiswe ngomoya.

 

3) Uhlelo Lokupholisa Umoya Lwephampu Yokushisa: Umgomo wohlelo lokupholisa umoya lwephampu yokushisa ufana nowesistimu yokupholisa umoya yemoto yendabuko. Kodwa-ke, uhlelo lokupholisa umoya lwephampu yokushisa lungashintsha phakathi kokushisa kwekhabhini nokupholisa. Ngenxa yokuthi umoya opholile wephampu yokushisa awusebenzisi amandla kagesi ngokuqondile ukuze ufudumale, ukusebenza kahle kwawo kwamandla kuphakeme kunokwezifudumezi ze-PTC. Njengamanje, izinhlelo zokupholisa umoya zephampu yokushisa sezivele zikhiqizwa ngobuningi kwezinye izimoto.
