Ibibazo bisanzwe by'icyuma gikonjesha gikoresha amashanyarazi

Muri sisitemu yo gukonjesha, ubushyuhe buva mu kirere n'umuvuduko uva mu kirere ni ibintu bifitanye isano.
Bifitanye isano n'ibintu byinshi nk'ubushobozi bwa kompreseri. Iyo kimwe mu bintu bihindutse, ubushyuhe bw'ibyuka n'umuvuduko w'ibyuka bya sisitemu yo gukonjesha bizahinduka uko bikwiye. Mu bubiko bukonje bwimukanwa bwa BZL-3×4
, agace gashyirwamo umwuka ntikahindutse, ariko ubushobozi bwa firigo bwako bwikubye kabiri, ibi bigatuma ubushobozi bwa evaporator igendanwa ikoreshwa mu kubika ibintu bikonje budahura n'ubushobozi bwo gukurura umwuka bwa compressor (ubushobozi bwa evaporator Vo)
Ni nto cyane ugereranyije n'ubushobozi bwo gukurura bwa kompreseri (Vh), ni ukuvuga V0Iyo ubushyuhe bw'umusatsi buri hasi cyane, igipimo cy'imikorere ya compressor kizagabanuka, kandi igipimo cy'ubukungu kizagabanuka.

1. Imiterere y'agace gashobora guhumekamo umwuka k'icyuma gishyushya ibikoresho bikonjesha hamwe ntabwo ifatika:

Imiterere y'agace gashyirwamo umwuka mu bubiko bukonje hamwe itandukanye cyane n'ibisabwa mu buryo bwa tekiniki mu buryo nyabwo bwo gukonjesha. Dukurikije ibyagaragaye aho ngaho ku bubiko bumwe na bumwe bushyirwamo umwuka, agace gashyirwamo umwuka mu mwuka ni ako gusa.
Hari hafi 75% bigomba gushyirwaho. Tuzi ko kugira ngo igikoresho gishyushya gikoreshwe mu bubiko bukonje, hagomba kubarwa imitwaro itandukanye y'ubushyuhe hakurikijwe ibisabwa mu bushyuhe bwacyo, kandi ubushobozi bwo gushyushya bwa igikoresho gishyushya bugomba kugenwa.
Agace k'umusatsi, hanyuma ugashyiraho hakurikijwe ibisabwa mu buryo bwo gukonjesha. Iyo evaporator idakozwe neza hakurikijwe ibisabwa mu gishushanyo kandi agace k'imashini ikoresha evaporator kagabanutse ku buryo butari bwo, evaporator yo mu bubiko bukonje yangirika.
Igipimo cyo gukonjesha kuri buri gice kiragabanuka cyane kandi umutwaro wo gukonjesha uriyongera, kandi igipimo cyo gukoresha ingufu kigabanuka cyane, bigatuma ubushyuhe mu bubiko bukonjesha bwimukanwa bugabanuka buhoro buhoro, kandi igipimo cyo gukora cya firigo gikunda kuzamuka.
Bityo rero, mu gihe cyo gushushanya no guhitamo icyuma gishyushya ubushyuhe cyo mu bubiko bwimukanwa, agace k'icyuma gishyushya ubushyuhe gakwiye gutoranywa hakurikijwe itandukaniro ryiza ry'ubushyuhe bwo kohereza ubushyuhe.

2. Imiterere y'icyuma gikonjesha cy'ibikoresho bikonjesha bivanze ntabwo ikwiye:

Ibikoresho byo gukonjesha byashyizwe ku bubiko bukonje buhuriweho n'inganda zimwe na zimwe ntibibarwa hakurikijwe umutwaro wose w'ubukonje ubarwa hakurikijwe imiterere y'ububiko n'ubunini bw'urwego rw'ubushyuhe rw'inyubako ikora yo kubikamo ubukonje.
Uburyo bwo gushyira mu bikorwa ibintu bikonjesha bukwiye, ariko uburyo bwo kongera umubare w'ibikoresho bikonjesha kugira ngo bihuze n'ibisabwa kugira ngo bikonjeshe vuba mu bubiko. Dufate urugero rw'ububiko bukonje bwa BZL-3×4 bwakozwe mbere, ububiko bufite uburebure bwa metero 4, ubugari bwa metero 3, kandi
Metero 2.7, ingano nyayo y'ububiko ni metero kibe 28.723, ifite amaseti 2 y'ibikoresho byo gukonjesha bya 2F6.3 seri na seti 2 z'ibikoresho byigenga byo gushyushya umuriro, buri gice n'igikoresho cyigenga cyo gushyushya umuriro bigizwe na
Sisitemu yuzuye yo gukonjesha kugira ngo ikonjeshe. Dukurikije isuzuma n'umutwaro w'imashini mu bubiko bukonje, birazwi ko umutwaro w'imashini mu bubiko bukonje ari hafi 140 (W/m3), kandi umutwaro nyawo ni
4021.22 (W) (3458.25kcal), hakurikijwe amakuru yavuzwe haruguru, ububiko bukonjesha bugendanwa buhitamo icyuma gikonjesha cya 2F6.3 (ubushobozi busanzwe bwo gukonjesha 4000kcal/h) gishobora kandi kuzuza ibisabwa mu bubiko bukonjesha bugendanwa.
Ibisabwa mu gutunganya ubukonje (kugeza kuri -15°C ~ -18°C), bityo rero, ni ngombwa gushyiraho indi mashini ikora ubukonje ku bubiko, kandi bizongera ikiguzi cyo kubungabunga icyuma.
