6. Kunanirwa kwa sisitemu yo gukonjesha

1. Gukonjesha ku mugozi w'isukari: gukonjesha ku mugozi w'isukari ntibigomba kurenza mm 3. Iyo gukonjesha ari binini cyane, ubushobozi bwo kwirinda ubushyuhe burazamuka, bigatuma habaho itandukaniro rinini ry'ubushyuhe hagati y'isukari n'ububiko bukonje. Isukari ntishobora kwinjiza ubushyuhe buhagije kugira ngo ihinduke mu mugozi. Ingano nini ya sukari ifata ubushyuhe ku mugozi ugarura ubushyuhe kandi ihinduke, ibyo byongera gukonjesha k'umugozi ugarura ubushyuhe; byongeye kandi, ubushyuhe bukabije bwumvishwa na valve yo kwagura ni buto cyane cyangwa na zeru, bigatuma ifunga cyangwa ifunga, kandi compressor izahagarara vuba. Ariko, valve ya solenoid ntabwo ifunze, kandi haracyariho umutwaro runaka w'ubushyuhe mu bubiko bukonje. Nyuma y'uko umuvuduko wa evaporator uzamutse, compressor yongera gutangira, bigatuma habaho gutangira kenshi. Uko ubukonje burushaho kuba bwinshi ku mugozi, niko iki kibazo kizaba kibi kurushaho. Mu by’ukuri, ubukonje buri ku miyoboro y’ubushyuhe bubiri buri mu bukonje buri hasi muri ubu buryo ni bwinshi cyane, bugera kuri cm 1-2, ibyo bigira ingaruka zikomeye ku ihererekanya ry’ubushyuhe kandi ntibishobora kugabanya ubushyuhe bwo kubika. Nyuma yo gushonga, ongera ukoreshe uburyo, maze ubushyuhe bw’ububiko bubiri buri mu bushyuhe buri hasi bushobora kugabanuka bukagera kuri dogere selisiyusi 6-5.

2. Agaciro k'igenamiterere ry'umuvuduko wo hejuru n'uwo hasi ntabwo ari byo: icyuma gikonjesha gikoreshwa mu bikoresho bikonjesha ni R22, kandi umuvuduko wo hejuru (umupaka wo hejuru) utoranywa cyane nk'umuvuduko wo gupima wa 1.7-1.9mpa. Umuvuduko (umupaka wo hasi) w'icyuma gikonjesha gishobora kuba umuvuduko wo hejuru n'ubushyuhe bwo gusohora umwuka -5°C (itandukaniro ry'ubushyuhe bwo kohereza ubushyuhe), ariko muri rusange ntabwo ari munsi y'umuvuduko wo gupima wa 0.01 MPa. Itandukaniro ry'urwego rwo guhindura rw'icyuma gikonjesha muri rusange ni 0.1-0.2MPa. Hari igihe igipimo cy'agaciro k'igenamiterere ry'umuvuduko ntabwo ari cyo, kandi agaciro nyako k'igikorwa gashingira ku gaciro kapimwe mu gihe cyo gukosora. Mu gihe ugerageza icyuma gikonjesha umuvuduko wo hasi, funga buhoro buhoro valve yo gukonjesha ya compressor, kandi witondere agaciro k'icyitegererezo cy'umuvuduko wo gukonjesha. Agaciro k'icyitegererezo iyo compressor ihagaritswe kandi igatangizwa ni imipaka yo hejuru n'iyo hasi y'icyuma gikonjesha umuvuduko wo hasi. Kugira ngo ugerageze icyuma gipima umuvuduko mwinshi, funga buhoro buhoro valve yo guhagarika gusohora ya compressor, hanyuma usome isomo ry'igipimo cy'umuvuduko wo gusohora iyo compressor ihagaze, ni ukuvuga umuvuduko wo guhagarika umuvuduko mwinshi. Emeza neza niba igipimo cy'umuvuduko cyizerwa mbere yo gukora ikizamini; kugira ngo urebe neza ko umutekano ari wose, valve yo gusohora umuvuduko ntigomba gufungwa burundu.

3. Umuti uhagije wo kubika ibyuma muri sisitemu: Mu gikoresho gifite ikigega cyo kubika amazi, bitewe n'imikorere yo guhindura ikigega cyo kubika amazi, keretse iyo hari ikibazo gikomeye cyo kubura icyuma gikonjesha, amazi atangwa n'ikigega cyo kubika amazi ntashobora gukomeza, ibyo bizagira ingaruka ku mikorere isanzwe y'igikoresho. "Umuti uke wo kubika amazi", ni ukuvuga urwego ruto rw'amazi, ntabwo bizagira ingaruka zikomeye ku mikorere ya sisitemu. Ariko, mu gikoresho kidafite ikigega cyo kubika amazi, kubera ko ingano y'umuti ukonjesha muri sisitemu igena neza urwego rw'amazi rwa icyuma gikonjesha muri kondenseri, bityo bigira ingaruka ku mikorere ya icyuma gikonjesha n'urwego rwo gukonjesha rw'icyuma gikonjesha amazi, iyo ingano y'umuti ukonjesha muri sisitemu Iyo idahagije, byanze bikunze bizatuma habaho impinduka zikurikira mu mikorere y'ibikoresho:

(1) Kompreseri ikomeza gukora, ariko ubushyuhe bwo kubika ntibushobora kugabanuka;

(2) Umuvuduko w'imyotsi isohoka muri kompreseri uragabanuka;

(3) Igitutu cyo gukurura cya kompreseri kiri hasi, ubushyuhe bukabije bwo gukurura buriyongera, ubukonje buri inyuma y'icyuma gishyuha burashonga, maze umutwe wa kompreseri ukarushaho gushyuha;

(4) Umubare munini w'udupira urashobora kugaragara mu gice cy'amazi gitembera mu kimenyetso cy'amazi;

(5) Igipimo cy'amazi cya kondensateri kiragaragara ko kiri hasi.

Iyo umwanya wo gufungura valve yo kwagura ubushyuhe ugabanijweho gato cyane, umuvuduko wo gukurura uzagabanuka, evaporator izakonja kandi ishonge, kandi umuyoboro wo gukurura uzakonja kandi ushonge. Kubwibyo, iyo urwego rwa firigo rudashobora kureberwa neza. Kugira ngo harebwe niba ingano ya firigo iri muri sisitemu idahagije, uburyo bukurikira bushobora gukoreshwa:

Hagarika gukoresha valve yo kwagura ubushyuhe, fungura kandi uhindure valve yo kwagura intoki neza, kandi urebe imikorere ya sisitemu kugira ngo urebe niba ishobora gusubira uko isanzwe. Niba ishobora gusubira uko isanzwe, bivuze ko valve yo kwagura ubushyuhe idahinduwe neza, bitabaye ibyo haba hari ibura rya refrigerant muri sisitemu. Refrigerant idahagije muri sisitemu (niba atari umuriro uhagije) ni yo mpamvu ituma habaho gusohora. Kubwibyo, nyuma yo kubona ko refrigerant ya sisitemu idahagije, gusohora kw'amazi bigomba kubanza kugaragara, hanyuma refrigerant ikongerwamo nyuma yuko gusohora kw'amazi.
