Iyo ubushyuhe bwo guhumeka bwa sisitemu yo gukonjesha ikonje iri munsi ya 0 ° C, igicu kizagaragara hejuru yubushyuhe, bigira ingaruka kumikorere yubushyuhe.Kubwibyo, defrosting isanzwe nayo ni igice cyingenzi cyo kubungabunga ububiko bukonje.Hariho inzira nyinshi zo guhagarika.Kugeza ubu, inganda zubaka zikonje zikoresha cyane cyane uburyo butanu: defrosting artificiel, defrosting electrique, defrosting air hot, defrosting water, defrosting water air defrosting.
1. Gukoresha intoki ni ugukuraho intoki urwego rwubukonje hejuru yumuyoboro usohora umwuka.Ubu buryo burashobora gukorwa nta guhagarika ibikoresho bya firigo.Ubu buryo butwara igihe kandi bukora cyane, kandi ingaruka ya defrosting ni mbi.
2. Gukwirakwiza amashanyarazi nugushiraho icyuma cyamashanyarazi kumashanyarazi kugirango ushushe hamwe nubushyuhe bwamashanyarazi.Mugihe cya defrosting, hagarika compressor cyangwa uhagarike kugaburira amazi kumashanyarazi.Gukwirakwiza amashanyarazi bifite ibyiza byo kugiciro gito no kugenzura byoroshye, ariko ikiguzi cyo gukora ni kinini.Mubisanzwe bikoreshwa mugukonjesha ibikoresho byo kubika bikonje, ntabwo ari ugukonjesha ibikoresho bya firigo.Kubushyuhe butandukanye, ibisabwa mubuhanga bwo kubika bigomba kuba bitandukanye, kandi ubushobozi bukenewe bwo gukonjesha nabwo bugomba kuba butandukanye.Ishyirwaho ryububiko bukonje rigomba gutegurwa ukurikije ibidukikije byabakiriya basaba nibisabwa, keretse niba bidakenewe gufata inzira yubuziranenge.
3. Gusohora gazi ishyushye ni ugukoresha amavuta ya firigo ashyushye asohoka na compressor kugirango arekure ubushyuhe mumashanyarazi hanyuma ashongeshe igice cyubukonje hejuru yumuyaga.Sisitemu ishyushye ya gaz defrosting iragoye kandi igiciro ni kinini.Ariko ingaruka ya defrosting nibyiza.Iyo ikoreshejwe muri sisitemu ya ammonia, amavuta yegeranijwe mumashanyarazi nayo ashobora gusohoka mumazi cyangwa ikigega cyumuvuduko muke.Muburyo bwo guhagarika gazi ishyushye, muri rusange igitutu kiyobowe na 0.6MPa.Gerageza gukoresha gaze yumuvuduko mwinshi wasohotse muri compressor imwe imwe kugirango defrosting.Igihe cy'itumba kirashobora kuba cyiza kugabanya amazi akonje cyangwa kugabanya umubare wa kondereseri, kongera ubushyuhe bwumuriro, kugabanya igihe cyo gukonja.Kuri sisitemu ya ammonia, ammonia ishyushye ya defrosting igomba guhuzwa numuyoboro usohora amavuta atandukanya amavuta.
4. Gukonjesha amazi ni ugutera amazi hejuru yumwuka hamwe nigikoresho cyo kumena kugirango ushongeshe ubukonje.Sisitemu yo gukuramo amazi ifite imiterere igoye nigiciro kinini, ariko ingaruka nziza nigiciro gito.Gukonjesha amazi birashobora gukuraho gusa ubukonje hejuru yinyuma yumuyaga, kandi ntibishobora gukemura ingaruka mbi zo kwegeranya amavuta mumashanyarazi kumashanyarazi.Ikintu cyingenzi cyane nububiko bukonje bukonje, busanzwe bukorwa hakiri kare nuwabikoze ububiko bukonje kandi bufite uburebure, ubugari nubugari.Ububiko bukonje bukonje bwa 100mm busanzwe bukoreshwa mububiko bwo hejuru n'ubushyuhe bwo hagati, 120mm cyangwa 150mm yububiko bukonje bukoreshwa mububiko bwubushyuhe buke no kubika ubukonje.
5 imbere.Iyo gukonjesha, gaze ishyushye ibanza koherezwa mumashanyarazi kugirango itandukane nubukonje hejuru yubushyuhe, hanyuma amazi aterwa kugirango akarabe vuba ubukonje.Amazi amaze guhagarikwa, ubuso bwumuyaga "bwumishijwe" numwuka ushushe kugirango wirinde firime yamazi hejuru gukonja kandi bigira ingaruka kumyuka yubushyuhe.Mubihe byashize, abakora ububiko bwububiko bukonje cyane bakoreshaga polyethylene na polystirene nkibikoresho.Noneho hari imikorere myiza yubuyobozi bwa polyurethane sandwich.Polystirene ifuro ifata ibintu byinshi ni bike, ntishobora gukingirwa.Mubisanzwe bikoreshwa mubikoresho bidasanzwe.Polyethylene ni ibikoresho byiza.Binyuze mu kigereranyo runaka, irashobora kubira ifuro bivuye mubucucike bukwiye, ingaruka zo gukumira ni nziza, imbaraga zikomeye zo gutwara ibintu.Isahani ya polyurethane nibyiza, ifite imikorere myiza yo gukingira kandi ntabwo ikurura ubuhehere, ariko iki giciro cyo kubika imbeho kiri hejuru gato.
