Nolosha Adeegga Sameeyaha Barafka

1. Falanqaynta Heerka Adeegga Nolosha ee Sameeyaha Barafka

Marka loo eego waraaqaha cad ee farsamada ee Ururka Injineerada Qaboojiyaha Mareykanka (ASHRAE) iyo soosaarayaasha caadiga ah (sida Hoshizaki iyo Manitowc):

1. Sameeyaha barafka ganacsiga: Celceliska maalinlaha sare -waqtiga shaqada xoojinta waa 8-10 saacadood, iyo nolosha naqshadeynta inta badan waa 5-10 sano. Tusaale ahaan, taxanaha SC ee Manitowoc ayaa si cad u sheegaya "Waxaa lagu talinayaa in la sameeyo qiimeyn qasab ah 10 sano kadib."

2. Baraf-sameeyaha qoyska: Deegaanka isticmaalka joogtada ah (sida 1-2 saacadood maalintii), nolosha adeeggu waxay gaari kartaa 8-15 sano. Tilmaamaha noocyada sida Wellcome ayaa sheegaya in "xilliga 8-da sano ee dammaanadda ee qaybaha asaasiga ah (compressors) ay tixraacayaan heerkan."

Cawaaqibta tooska ah ee isticmaalka xad dhaafka ah-waxaa ka mid ah:

- Hoos u dhaca waxtarka tamarta: Isticmaalka tamarta moodooyinka ka weyn 10 sano waxa laga yaabaa in 35% ka sarreyso ta moodooyinka cusub (xogta warbixinta 2022 ENERGY STAR);

- Khatarta nadaafadda: isu-ururinta miisaanku waxay sababi doontaa in tirada guud ee gumaysigu ay dhaafto heerka. NSF/ANSI 12-2020 waxa ay qeexaysaa in bakteeriyada hadhaaga ah ee ku jirta uumiga ay tahay in ay ka yaraato ama la mid noqoto 100 CFU/cm², iyo qalabkii hore ay u nugul yihiin in uu dhaafo heerka caadiga ah.

2. Xadka adag ee nolosha adeegga ugu badan ee mishiinnada barafka
Inkasta oo qalabka qaarkood ay shaqayn karaan in ka badan 15 sano, saddex nooc oo tilmaamayaal ayaa go'aaminaya in la tirtiro:

1. Heerarka badbaadada: ASME BPA-2021 waxay u baahan tahay in qaybaha weelka cadaadiska (sida kondhiyeeriyeyaasha) ee la isticmaalay in ka badan 12 sano waa in la mariyaa tijaabooyinka caabbinta cadaadiska sannad kasta;

2. Heerka waxqabadka: Marka mugga wax-soo-saarka barafka uu hoos ugu dhaco 60% qiimaha magaca (sida 24kg asalka ah ee mashiinka maalintii oo kaliya wuxuu soo saaraa 14kg), wuxuu gaaraa barta xoqitaanka farsamada ee ay aqoonsan tahay warshadaha;

3. Dib-u-habaynta nidaaminta: Kadib 2020, xeerarka ERP ee EU waxay u baahan yihiin in qiimaha COP ee mashiinada cusub uu ka weyn yahay ama la mid yahay 2.1. Noocyadii hore ee ka horeeyay 2005 guud ahaan waa 1.3-1.8 kaliya, isticmaalka sii socdaa waxa uu wajihi karaa arimo u hogaansanaan.

III. Talooyin wax ku ool ah oo loogu talagalay kordhinta nolosha
- Daaweynta tayada biyaha: Ku rakibida jilciye biyaha waxay kordhin kartaa nolosha uumiga 40% (xogta tijaabada ee Shaybaadhka Scotsman);

- Dayactirka saddex-biloodlaha ah: Inta jeer ee nadiifinta baalasha qaboojiyaha iyo beddelka walxaha shaandhada ayaa 72% la xidhiidha heerka guul-darradu (tirakoobka Ururka Warshadaha Qaboojiyaha iyo Qaboojiyaha Japan);

- Maaraynta culayska: Xaaladaha ganacsiga, waxa lagu talinayaa in la xidho 15 daqiiqo 2dii saacadoodba ee hawlgalka si loo yareeyo khasaaraha kombaresarada.
