Mu gihe cyizuba cyangwa imbeho ikonje, ubukonje bwimodoka nibyingenzi kuri twe abakunda imodoka, cyane cyane iyo idirishya ryijimye cyangwa ubukonje hejuru. Ubushobozi bwa sisitemu yubushyuhe bwo guhumeka vuba na defrost bigira uruhare runini mumutekano wo gutwara. Ku binyabiziga byamashanyarazi, bidafite moteri ya lisansi, ntabwo bifite isoko yubushyuhe bwo gushyushya, kandi compressor ntabwo ifite imbaraga zo gutwara moteri kugirango itange ubukonje. Nigute ibinyabiziga byamashanyarazi bitanga uburyo bwo gukonjesha no gukonjesha? Reka tubimenye.
01 Ibigize sisitemu yo gukonjesha
Ibigize sisitemu yo gukonjesha ikirere harimo: compressor yamashanyarazi, kondenseri, sensor yumuvuduko, icyuma cyaguka cya elegitoronike, impumatori, imiyoboro ikonjesha, imiyoboro ikomeye, hamwe n’umuzunguruko.
Compressor:
Ifata ubushyuhe buke hamwe na firigo ya gaze yumuvuduko ukabije kandi ikabigabanya mubushyuhe bwo hejuru hamwe na gaze ya firigo ya firigo. Mugihe cyo kwikuramo, leta ya firigo ntigihinduka, ariko ubushyuhe nigitutu bikomeza kwiyongera, bikora gaze yubushyuhe.
Umuyoboro:
Kondenseri ikoresha umuyaga wabigenewe kugirango ugabanye ubushyuhe bwubushyuhe bwo hejuru hamwe na firigo yumuvuduko mwinshi mukirere gikikije, bikonjesha firigo. Muri ubu buryo, firigo ihinduka kuva muri gaze ikajya mumazi, kandi iri mubushyuhe bwinshi kandi bwumuvuduko mwinshi.
Kwagura Agaciro:
Ubushyuhe bwo hejuru hamwe n’umuvuduko ukabije wa firigo unyura muri valve yaguka kugirango ugabanye kandi ugabanye umuvuduko mbere yo kwinjira mumashanyarazi. Intego yiki gikorwa ni ugukonjesha no guca intege firigo no kugenzura imigendekere yo kugenzura ubushobozi bwo gukonja. Iyo firigo inyuze muri valve yagutse, ihinduka kuva mubushyuhe bwo hejuru, umuvuduko ukabije uhinduka ubushyuhe buke, umuvuduko ukabije wamazi.
Impumura:
Ubushyuhe buke, ubukonje buke bwa firigo ikomoka muri valve yagutse ikuramo ubushyuhe bwinshi buturuka kumyuka ikikije umwuka mubi. Muri iki gikorwa, firigo ihinduka kuva mumazi ikajya mubushyuhe buke, gaze ya gaze. Iyi gaze noneho yomekwa na compressor kugirango yongere yongere.
Duhereye ku ihame ryo gukonjesha, sisitemu yo guhumeka ibinyabiziga byamashanyarazi ahanini ni nkibya moteri gakondo ikoreshwa na lisansi. Itandukaniro ahanini riri muburyo bwo gutwara imashini ikonjesha. Mu binyabiziga gakondo bikoreshwa na lisansi, compressor itwarwa numukandara wa moteri, mugihe mumodoka yamashanyarazi, compressor igenzurwa nubugenzuzi bwa elegitoronike kugirango itware moteri, nayo ikora compressor ikoresheje igikonjo.
02 Sisitemu yo gushyushya ikirere
Inkomoko yo gushyushya iboneka cyane binyuze muri PTC (Positive Temperature Coefficient). Imodoka zifite amashanyarazi meza muri rusange zifite uburyo bubiri: module ya PTC yo gushyushya ikirere na module ya PTC yo gushyushya amazi. PTC ni ubwoko bwa semiconductor thermistor, kandi ibiranga ni uko kurwanya ibikoresho bya PTC byiyongera uko ubushyuhe buzamuka. Munsi ya voltage ihoraho, umushyushya wa PTC urashyuha vuba mubushyuhe buke, kandi uko ubushyuhe buzamuka, ubukana bwiyongera, amashanyarazi aragabanuka, ningufu zikoreshwa na PTC ziragabanuka, bityo bikomeza ubushyuhe burigihe.
Imiterere yimbere yubushyuhe bwo mu kirere PTC Module:
Igizwe na mugenzuzi (harimo na voltage ntoya / nini ya voltage yo hejuru ya module), umuyoboro mwinshi / wumuvuduko ukabije wicyuma cyuma, amashanyarazi ya PTC ashyushya amashanyarazi, amashanyarazi ya silicone yamashanyarazi, hamwe nigikonoshwa cyo hanze, nkuko bigaragara ku gishushanyo.
Gushyushya ikirere PTC module isobanura gushyiraho PTC muburyo bwimikorere ya kabine ishyushye. Umwuka wa kabine uzengurutswe na blower hanyuma ushyutswe na hoteri ya PTC. Filime irwanya ubushyuhe imbere yubushyuhe bwo mu kirere PTC ikoreshwa na voltage nyinshi kandi igenzurwa na VCU (ishami rishinzwe kugenzura ibinyabiziga).
03 Kugenzura Sisitemu Yumuyaga Wumuyaga
Ikinyabiziga gifite amashanyarazi VCU gikusanya ibimenyetso bivuye kuri A / C, icyerekezo cya A / C, ubushyuhe bwa moteri, umuvuduko wumuyaga, nubushyuhe bwibidukikije. Nyuma yo gutunganya no kubara, itanga ibimenyetso byo kugenzura, byoherezwa mugenzuzi woguhumeka binyuze muri bisi ya CAN. Igenzura rihumeka igenzura kuri / kuzimya umuyagankuba mwinshi wa compressor yo guhumeka, nkuko bigaragara ku gishushanyo.
Ibyo bisoza kumenyekanisha muri rusange uburyo bwo guhumeka ibinyabiziga byamashanyarazi. Wabonye ko bifasha? Kurikiza Yiyi Ibinyabiziga bishya byingufu kubumenyi bwumwuga bisangirwa buri cyumweru.
