Isingeniso: Ikhodi Yobunjiniyela Yokuqina
Emisebenzini yezohwebo yokugcina ukudla kubanda (cold chain), ukuthembeka kwemishini kuthinta ngqo ukuphepha kokudla kanye nezindleko zokusebenza. Amafriji akwa-Misenhio afinyelela izinga lokwehluleka ngonyaka eliholela embonini elingaphansi noma lilingane no-≤0.8% ngezinqubo zokukhiqiza ezihlelekile—Umthombo wedatha: I-China Refrigeration Industry Association 2023 Reliability White Paper. Lokhu kuhlaziya kubheka izindawo ezinhlanu eziyinhloko zobuchwepheshe ngokuya ngezindinganiso ze-ISO 15502 kanye nemibhalo yobuchwepheshe esemphakathini: ubuchwepheshe bokuvala ikhabhinethi, ukusetshenziswa kwamaphaneli okufakwa kwe-vacuum (VIP), ukulinganisa uhlelo lokupholisa nge-COP≥3.5, ukulawulwa kwe-EMC, kanye nokuhlolwa komthwalo oqhubekayo kwamahora angu-72.
I. Ukukhiqizwa Kwekhabethe: Ukulawulwa Kokuvala Kwezinga Le-Micron
I-laser welding ithatha indawo ye-riveting yendabuko, igcina izikhala zokuhlangana zingaphansi kuka-0.2mm. Umthombo wedatha: Incwadi Yezobuchwepheshe ye-Misenhio Rev.2024-07. Izilawuli ezibalulekile zenqubo zihlanganisa:
- Ubuningi be-polyurethane foam: Kugcinwa ngokuqinile ku-42±2kg/m³ ngesilinganiso samaseli avaliwe okungu-≥92%, kuqinisekiswa ukuthi ukushisa kuhamba kahle ≤0.020W/(m·K)
- Ukuqina kokuvala komnyango: Kuhlolwa ngomehluko wokucindezela ongu-50Pa nokuvuza komoya okungaphansi kuka-3m³/h
- Idizayini yokuvimbela ukujiya: Amandla okushisa e-strip angu-1.8W/cm ahambisana ngokuguquguqukayo nomswakama wezindawo ezizungezile
II. Uhlelo Lokupholisa: Ukulinganisela Kokusebenza Nokuqina
Ukuhlelwa kwamapayipi okuthuthukisiwe kusetshenziswa amamodeli we-3D simulation we-ASHRAE:
Ingxenye | Inqubo Yokucubungula | Inkomba Yezimboni |
I-Compressor | COP≥3.5 @-25℃ | COP≥2.8 |
I-Condenser | Isikhala se-fin esingama-2.0mm | 2.5-3.0mm |
Inani le-refrigerant | Ukubekezeleka okungu-±1.5% | ±5% |
Umthombo wedatha: GB/T 20154-2023 Izinga Lobuchwepheshe Lesiqandisi Sezohwebo
Ukuhlaziywa kwe-spectrum yokudlidliza kugcina i-amplitude ye-compressor ingaphansi kuka-25μm, kwandisa impilo yokusebenza ngo-30% Umthombo wedatha: Umbiko Wokuhlolwa Kwelebhu yase-Misenhio No.CL2024-086.
III. Uhlelo Lokuqinisekisa Ukwethembeka
Umgomo wokuqinisekisa womjikelezo wempilo emithathu:
- Ukulingiswa kwemvelo: imijikelezo engu-200 ku--40℃~55℃ ngokuzinza kwezinga lokushisa elingu-±0.3K
- Ukuhlolwa kwengcindezi yemishini: ukudlidliza kwamahora angu-6 nge-acceleration engu-7m/s²
- Ukubekezela komthwalo: imijikelezo engu-5000 yokuvula/ukuvala ngomthamo ogcwele ngezikhathi ezingaphansi kuka-3min
IV. Ukuhlaziywa Komthelela Wezimboni
Lolu hlelo lokukhiqiza luqhuba intuthuko emibili yezimboni:
"Ukuqaliswa kwe-VIP kunciphisa ubukhulu bodonga lwekhabethe ngama-40%, kunciphisa indawo ehanjiwe ngo-15% ngomthamo olinganayo"
——Zhang Ming, Ikomidi Lokumiswa Kwemishini Yeketanga Elibandayo
Ukubuyekezwa okusheshisiwe kwe-GB/T 20154-2023, kuyala ukuthi amayunithi ezohwebo asebenzise amandla angaphansi noma alingane no-≤850kWh/m³ ngonyaka Umthombo wedatha: Isimemezelo se-SAMR No.45/2023.
