Abangane abaphethe izitolo zama-dessert noma izitolo ezithengisa izinto ezishibhile kungenzeka ukuthi bake babhekana nalesi simo esididayo: Ama-ayisikhilimu amabili aqandisiwe abekwe ku--18°C angasebenzisa ugesi ongu-5 kWh ngosuku, kanti omunye usebenzisa u-10 kWh. I-ayisikhilimu esanda kufakwa igcina ukuthungwa kwayo okubushelelezi kwamanye ama-freezer, kodwa ihlala ikhula iqhwa futhi iqine kwamanye. Iqiniso liwukuthi, ukujiya kwengqimba yokushisa kunquma umphumela ngokuthula.
Abaningi bacabanga ukuthi “ukufakwa kokuvikela okujiyile kungcono ngaso sonke isikhathi,” kodwa osomabhizinisi abangochwepheshe bayazi ukuthi ukujiya okungafanele kuchitha amandla nemali noma kudle indawo yokugcina izinto.
I. Ubukhulu Bokufakwa Kokushisisa Okuvamile busukela ku-50-100mm, Obulungiselelwe Izimo Ezithile
Asikho isidingo sokusesha ngokungapheli—ububanzi bokujiya kokuvikela amakhabethe e-ayisikhilimu buphakathi kuka-50-100mm. Kodwa-ke, lokhu akuyona inani elinqunyiwe. Izimo ezahlukene zokusetshenziswa kanye nezidingo zokushisa zidinga ukujiya okuhluke ngokuphelele.
| Isimo Semodeli/Sohlelo Lokusebenza | Ibanga Lokushisa Eliqondiwe | Ubukhulu Bokushisisa Obunconyiwe | Isizathu Esiyinhloko |
|---|---|---|---|
| Amafriji e-ayisikhilimu amancane asetshenziswa ekhaya (amancane aqonde phezulu/avundlile) | -12°C kuya ku-18°C | 50-70mm | Ukusetshenziswa kwekhaya okuvamise ukuba mfushane kudinga ubukhulu obuncane bokushisa; kulinganisela umthamo wokugcina nezidingo zokugcina izinga lokushisa eziyisisekelo |
| Amakhabethe Okubonisa Ajwayelekile Ezentengiselwano (Isitolo Sokunethezeka/Isitolo Sama-dessert Esiqondile) | -18℃~-22℃ | 70-90mm | Ukuvulwa kweminyango njalo (okuningi nsuku zonke), okudinga ibhalansi phakathi kokugcinwa kwezinga lokushisa nendawo yokubonisa ukuze kuvinjelwe ukulahleka okusheshayo komkhuhlane |
| Amayunithi Ezentengiselwano Angaphandle/Amazinga Okushisa Aphezulu (Izimakethe Zasebusuku/Izindawo Zokuthengisa Ezivulekile) | -18°C kuya ku-25°C | 90-100mm | Ukushintshashintsha okukhulu kwezinga lokushisa (isb., ngaphandle kwasehlobo okungu-35℃+, ngaphakathi kwamakhabethe -20℃). Ukufakwa kokushisa okujiyile kunciphisa ukusetshenziswa kwamandla futhi kuvimbela ukuminyana kwamakhabethe. |
| Amakhabethe Okugcina Izinto Ezishisayo Eziphansi Kakhulu (Izitolo Ezinkulu/I-Ice Cream Ethengiswa Ngobuningi) | Ngaphansi kuka -25°C | 100-150mm | Indawo yokugcina izinto esezingeni lezimboni idinga amazinga okushisa aphansi kakhulu kanye nokugcinwa kokushisa okuqinile; ukufakelwa kwe-PU foam okunobukhulu obuphezulu kuvame ukusetshenziswa, futhi ukujiya okunganele kungaholela ekonakalisweni kwe-ayisikhilimu. |
Inothi elikhethekile: Ukugcinwa kwe-ayisikhilimu kudinga amazinga aqinile okushisa. Njengoba ochwepheshe abaningi bokugcina i-ayisikhilimu behlanganyela ezinkundleni ezifana ne-Douyin, ukugcinwa kwe-ayisikhilimu ku--22°C kuya ku--25°C kudinga izendlalelo zokushisa okungenani u-15cm (150mm) ubukhulu ukuze kusetshenziswe kahle amandla. Nakuba amakhabethe e-ayisikhilimu engadingi lobu bukhulu, amamodeli okushisa aphansi kakhulu akufanele awe ngaphansi kuka-100mm.
II. Lezi Zici Ezi-4 Zibalulekile Ekusebenzeni Kahle Kokufudumeza
Amabhizinisi amaningi agxila kuphela ekujiyeni lapho ethenga, enganaki izici ezibaluleke kakhulu. “Amandla okugcina ukushisa” ephaneli empeleni ancike emiphumeleni ehlanganisiwe yokujiya, izinto zokwakha, inqubo yokukhiqiza, kanye nesakhiwo—ukumane nje ukwengeza ukujiya akusebenzi ngaso sonke isikhathi.
1. Umehluko Omkhulu Wezinga Lokushisa Udinga Amaphaneli Aqinile
Umsebenzi oyinhloko wokuvala ukushisa ukuvimba ukushintshana kokushisa phakathi kwangaphakathi nangaphandle. Umehluko omkhulu wokushisa udinga ukujiya okukhulu. Isibonelo, endaweni yangaphakathi engu-25°C, ikhabethe le-ayisikhilimu elingu--18°C lidinga ukujiya okungu-70mm. Kodwa-ke, uma libekwe esitobhini sangaphandle esingu-38°C, ukugcina izinga lokushisa elifanayo kudinga ukwandisa ukujiya kube ngaphezu kuka-90mm. Lokhu kufana nokugqoka ijazi eliphansi ebusika: uhlobo olujiyile luyadingeka ezindaweni ezisenyakatho ku--20°C, kanti oluncane lunele ezindaweni eziseningizimu ku-5°C.
2. I-Mainstream PU Foam: Ubuningi bubaluleke ngaphezu kobukhulu
Cishe wonke amakhabhinethi e-ayisikhilimu asebenzisa i-rigid polyurethane (PU) foam insulation. Le nto inezinga lamaseli avaliwe elingafika ku-95% kanye ne-thermal conductivity ephansi njengo-0.018-0.024 W/(m·K), okwenza kube "okuphelele" kwe-insulation. Kodwa-ke, qaphela: Ubuningi be-PU foam kumele bube ≥40kg/m³; ngaphandle kwalokho, noma ngabe ubukhulu obanele, izikhala zangaphakathi zizolimaza i-insulation. Abanye abakhiqizi banciphisa izindleko ngokusebenzisa i-honeycomb foam esikhundleni se-solid foam, behlisa ukusebenza kwe-insulation ngo-30%. Ngisho noma ibhalwe njengobukhulu obungu-80mm, ukusebenza kwayo kwangempela akufiki ku-50mm ye-PU foam esezingeni eliphezulu.
3. Ukufakwa Kokushibilika Okukhulu Kokuvulwa Kweminyango Okuvamile
Amakhabethe e-ayisikhilimu esitolo esilula, avulwa kaninginingi nsuku zonke ngamakhasimende, alahlekelwa ngokushesha umkhuhlane, adinga ukufudumala okungu-20mm ubukhulu kunamayunithi asekhaya. Amamodeli angaphandle awabhekani nokushintshashintsha kwezinga lokushisa okukhulu kuphela kodwa futhi nokukhanya kwelanga okuqondile kanye nokuchayeka esimweni sezulu, okudinga ukuqina okwengeziwe okungu-10-20mm. Ngokuphambene nalokho, amayunithi asekhaya anemvamisa yokuvula ephansi adinga ukufudumala okuphezulu okungu-50mm kuphela. Ukuqina ngokweqile kudla indawo yokugcina ebalulekile.
4. Ukuvimbela "Imiphumela Yebhuloho Lokushisa" Kudlula Ukujiya
Amanye amakhabethe e-ayisikhilimu ayahluleka ukugcina ubanda naphezu kobukhulu obanele ngenxa “yokubopha okushisa.” Isibonelo, ama-bracket ensimbi aklanywe kabi noma ama-gasket omnyango asebenza “njengezimbobo esudini elivalekile,” okuvumela ukushisa ukuthi kuphume ngqo. Lokhu kuchaza ukuthi kungani abanye abakhiqizi bengeza ukuvikela okwengeziwe ezinhlanganisweni zensimbi—ngisho noma ukuvikela okuncane kakhulu, ukusebenza kwabo kudlula imikhiqizo evalekile futhi evalekile kahle.
III. Ukukhetha Ubukhulu Obufanele Kungonga Izindleko Ezinkulu Zikagesi Njalo Ngonyaka
Ubukhulu bokufakwa kokushisa buthinta ngqo izikweletu zikagesi. Ifomula elula yokudlulisa ukushisa ichaza ukuthi kungani: izinga lokudlulisa ukushisa lilingana nobukhulu obuhlukile. Ubukhulu obukhulu benza ukungena kokushisa kube nzima, kunciphisa isidingo sokusebenza njalo kohlelo lokupholisa futhi kunciphisa ukusetshenziswa kwamandla ngokwemvelo.
Cabanga ngalesi sibonelo sangempela: Ikhabethe le-ayisikhilimu lesitolo esithengisa izinto ezisezingeni eliphezulu elinomshini wokushisa ongu-70mm lisebenzisa ama-kWh angu-8 nsuku zonke. Ngemva kokulishintsha ngekhabethe elinobukhulu obungu-90mm lomodeli ofanayo, ukusetshenziswa kwansuku zonke kwehle kwaya ku-5.5 kWh. Ngesilinganiso sezentengiselwano esingu-1.2 yuan/kWh, ukonga kwaminyaka yonke kufinyelela ku-(8-5.5) × 365 × 1.2 = 1,095 yuan. Kodwa-ke, qaphela ukuthi ngaphezu kobukhulu obungu-100mm, ukonga amandla kuncipha kancane. Isibonelo, ikhabethe elingu-120mm longa kuphela u-0.3 kWh owengeziwe nsuku zonke uma kuqhathaniswa nomodeli ongu-100mm, kodwa kunciphisa umthamo wokugcina ngo-15% - okwenza kube yinto engasizi ngalutho.
IV. Amathiphu Amathathu Okugwema “Ubukhulu Bokuzenzisa” kanye “Nobuciko Obungebuhle”
Imboni inamaqhinga ayo, njengokulebula ubukhulu obungu-80mm kodwa ilebula u-60mm kuphela, noma ukuhlangabezana nezindinganiso zobukhulu ngamasu angaphansi kwe-foam. Nazi izindlela ezintathu ezilula zokuhlola lezi zinkinga ngaphandle kwamathuluzi akhethekile:
1. Kala: Ngenxa yomthamo ofanayo, amayunithi asindayo athembeke kakhulu.
I-PU foam esezingeni eliphezulu inobukhulu obukhulu, okwenza kube nzima ngokwemvelo. Isibonelo, amakhabethe amabili e-ayisikhilimu angu-153L: imodeli yekhwalithi ephezulu ingaba nesisindo esingu-62 jin (cishe amakhilogremu angu-31.5), kanti esezingeni eliphansi ingaba yi-48 jin kuphela (cishe amakhilogremu angu-24.8). Lesi sisindo esilula cishe sibonisa ukuminyana kwe-foam okunganele noma ukujiya okuncishisiwe.
2. Hlola igebe phakathi kwesivalo nomzimba wekhabhinethi
Imichilo yokuvala “iyisihluthulelo esiwusizo” sokuvala. Kufanele izwakale ithambile uma icindezelwa futhi yakhe uphawu oluqinile, olungenazikhala ngokumelene nekhabhinethi uma ivaliwe. Ukuqhekeka noma ukuvuvukala emakhoneni ekhabhinethi kubonisa ukusatshalaliswa kwegwebu okungalingani, okungase kubonise izikhala kungqimba lokuvala.
3. Hlola izinga lokushisa lobuso: Ngemva kwamahora ama-2 okusebenza, ubuso bekhabhinethi akufanele bubonise ukujiya noma ukushisa okweqile.
Ngemva kwamahora ama-2 okusebenza, thinta ingaphandle lekhabhinethi. Uma kuvela ukujiya (ukujuluka) noma kuzwakala kushisa kakhulu, lokhu kubonisa ukufudumala okubi—kungaba ukujiya okunganele noma izinkinga zezinto/zokukhiqiza. Ngaphansi kwezimo ezijwayelekile, izinga lokushisa lobuso lekhabhinethi kufanele libe seduze nokushisa okuzungezile, lizizwe lipholile kancane.
V. Qinisekisa Lezi Zimiso Ukuze Ugweme Imikhiqizo Engaphansi Kwezinga Elifanele
Amakhabethe e-ayisikhilimu asemthethweni kumele ahambisane nezindinganiso ezifanele, njenge-GB 4706.1 “Ukuphepha Kwezinto Zikagesi Zasekhaya Nezifanayo” kanye ne-T/CAR 12—2022 “Ukuhlukaniswa, Izidingo, kanye Nemibandela Yokuhlola Yamafriji E-ayisikhilimu.”
Nakuba lezi zindinganiso zingaphoqeleli ukujiya okuthile, zibeka izidingo ezicacile ekusebenzeni kokushisa. Isibonelo, i-coefficient yokudlulisa ukushisa (inani le-K) kumele ibe phansi ngokwanele ukuqinisekisa amazinga okushisa angaphakathi afanayo kanye nokuhambisana nokusebenza kahle kwamandla.
Uma uthenga, cela umthengisi ukuthi anikeze imibiko yokuhlola. Gxila “ku-coefficient yokudlulisa ukushisa” kanye “nobuningi be-foam bengqimba yokushisa.” Uma lezi zilinganiso ezimbili zihlangabezana nezindinganiso, zihlanganiswe nobubanzi bokujiya okukhulunywe ngabo ngaphambilini, uzogwema kakhulu izingibe.
Okubalulekile:Ungabeki phambili ngokunganaki ubukhulu bokushisisa kwamakhabethe e-ayisikhilimu. Khetha u-50-70mm wokusetshenziswa ekhaya, u-70-90mm wokusetshenziswa kwezentengiselwano zangaphakathi, kanye no-90-150mm wokusetshenziswa kwezinga lokushisa langaphandle/eliphansi kakhulu. Beka phambili ukuminyana kwe-PU foam kanye nenqubo yokukhiqiza, bese ulungisa ngokusekelwe ezimweni zokusetshenziswa. Lokhu kuqinisekisa ukushisisa okusebenzayo ngaphandle kokuchitha isikhala noma izindleko zikagesi.
