Bophelo ba Tšebeletso ea Moetsi oa Leqhoa

1. Analysis of Standard Service Life of Ice Maker

Ho ea ka lipampiri tse tšoeu tsa tekheniki tsa American Society of Refrigeration Engineers (ASHRAE) le bahlahisi ba ka sehloohong (ba kang Hoshizaki le Manitowoc):

1. Moetsi oa leqhoa oa khoebo: Kakaretso ea letsatsi le letsatsi-e sebetsang ka matla haholo ke lihora tse 8-10, 'me bophelo ba moralo hangata ke lilemo tse 5-10. Ka mohlala, letoto la SC la Manitowoc le bolela ka ho hlaka "Ho kgothaletswa ho etsa tlhahlobo e tlamang ka mor'a lilemo tse 10."

2. Moetsi oa leqhoa oa lelapa: Sebakeng sa tšebeliso ea nakoana (joalo ka lihora tse 1-2 ka letsatsi), bophelo ba tšebeletso bo ka fihla lilemo tse 8-15. Litaelo tsa lihlahisoa tse kang Wellcome li bolela hore "nako ea lilemo tse 8 tsa tiisetso bakeng sa likarolo tsa mantlha (li-compressors) li bua ka mokhoa ona."

Litlamorao tse tobileng tsa ho feta{0}}tšebeliso e lekanyelitsoeng li kenyelletsa:

- Ho fokotseha ha matla a matla: Tšebeliso ea matla ea mefuta ea khale ho feta lilemo tse 10 e ka ba 35% ho feta ea mefuta e mecha (boitsebiso bo tsoang tlalehong ea 2022 ENERGY STAR);

- Likotsi tsa bohloeki: ho bokella sekala ho tla etsa hore palo eohle ea likolone e fete maemo. NSF/ANSI 12-2020 e bolela hore libaktheria tse setseng ka har'a mouoane li tlameha ho ba Ka tlase ho kapa ho lekana le 100 CFU/cm², 'me lisebelisoa tsa khale li tloaetse ho feta maemo.

2. Moeli o thata oa bophelo bo phahameng ba tšebeletso ea mechine ea leqhoa
Leha lisebelisoa tse ling li ka sebetsa ka lilemo tse fetang 15, mefuta e meraro ea matšoao e etsa qeto ea hore e tlameha ho felisoa:

1. Litekanyetso tsa polokeho: ASME BPA-2021 e hloka hore likarolo tsa sekepe sa khatello (tse kang li-condensers) tse 'nileng tsa sebelisoa ka lilemo tse fetang 12 li tlameha ho ba tlas'a liteko tsa ho hanyetsa khatello selemo le selemo;

2. Tsela ea ts'ebetso: Ha tekanyo ea tlhahiso ea leqhoa e theohela ho 60% ea boleng ba lebitso (joalo ka mochine oa pele oa 24kg / letsatsi o hlahisa 14kg feela), o fihla boemong ba ho lahla botekgeniki bo amoheloang ke indasteri;

3. Phetoho ea taolo: Kamora 2020, melaoana ea EU ERP e hloka hore boleng ba COP ba mechini e mecha e be Bo boholo ho feta kapa bo lekane le 2.1. Mehlala ea khale pele ho 2005 hangata ke 1.3-1.8 feela, 'me tšebeliso e tsoelang pele e ka tobana le mathata a ho latela melao.

(Tshehetso ea lintlha: Sehlomathiso C sa khatiso ea 2021 ea Hoshizaki "Ice Machine Life Cycle Report").

III. Litlhahiso tse sebetsang tsa ho lelefatsa bophelo
- Phekolo ea boleng ba metsi: Ho kenya mochini o hloekisang metsi ho ka lelefatsa bophelo ba mouoane ka 40% (lintlha tsa tlhahlobo ho tsoa Scotsman Laboratory);

- Tlhokomelo ea kotara: Khafetsa ea ho hloekisa mapheoana a condenser le ho nkela sefa sebaka ke 72% e tsamaellanang le sekhahla sa ho hloleha ho sebetsa (lipalo-palo tse tsoang ho Mokhatlo oa Indasteri oa Sehatsetsi sa Japane le Moeeng);

- Taolo ea mojaro: Maemong a khoebo, ho khothaletsoa ho koala metsotso e 15 ka lihora tse ling le tse ling tse 2 ho fokotsa tahlehelo ea komporo.
