Ivyuma bihindura ubushuhe (MCHEs): Guhindura Ibice vya CRAC ku bijanye n'ubushobozi bw'Ikigo c'Amakuru

Ku bibanza vy’amakuru, Igikoresho co gukoresha mu kirere (CRAC) ni ugukora - - kugira ngo umuntu agume afise ubushobozi bwo gukora neza no kugabanya PUE (Igikoresho c’Ikoreshwa ry’Igikoresho). Igiharuro ca kera- ibikoresho bihindura ubushuhe akenshi bigwa mu nzira y’ubuto -biretse, ntibikora neza, kandi bifise akamaro kanini -. KwinjiraIvyuma bihindura ubushuhe (MHEs): vyakozwe n’imirongo y’uruja n’uruza rw’urugero ruto (0.1–2 mm), urutonde rw’ibintu vyose-aluminum, n’ugutera ivyatsi, MHEs zitorera umuti izo ngingo z’ububabare mu gihe zitanga agaciro kaboneka ku bikorwa vy’imbere y’amakuru. Below ni uko bagaragara cane, hamwe n’ibintu vy’agaciro bituma ingaruka zavyo zirushiriza kuba nyinshi.

Ivyiza vy'ugusaba: Gukoresha Amanota manini manini y'Ikigo c'Imibano

MHEs ntizishobora gusa "gutera imbere" gusa ku bikoresho vya kera-birasubiramwo ivyo bishoboka ku bibanza vy'amakuru vyibanze ku bushobozi, ikibanza, igiciro, n'ukwizigirwa.

1. 30–50% vy'ubushuhe bwo hejuru=PUE yo hasi

Ivyumba vy'amakuru birwana kugira ngo PUE igume munsi ya 1.3- N MCHEs ni intwaro y'ibanga. Imirongo yayo mito mito ituma haba ahantu h’imbere cane (200–350 m2/m3, 2–3x y’ibigereranyo vy’imirongo y’amazi ({15}} ibigereranyo), bikaba bihatira ibikoresho (nk’uko R134a canke R410A) mu nzira ikomeye y’umuvurungano (Reynolds inomero ya Reynolds Re > 2300). Ivyo bica bigabanya ubushobozi bwo guhangana n’ubushuhe, bikasunika igipimo co guhindura ubushuhe ku 400–600 W/(m2·K) (vs. 200–300 W/(m2·K) ku bijanye n’uruzitiro).

Ivyo bisigura kuri wewe: Ku muzigo w'ugukonjesha 100 kW, MHEs zica ubushuhe bwo gukora ku 3–5℃. Buri rwego rwo hejuru 1 rugabanya ubushobozi bwo gukoresha amashanyarazi ku rugero rwa 2–3%, zihindura 25–35% zikoresha inguvu za CRAC. Ku kibanza c'amakuru 1000 m2, ivyo ni 30.000–42 kWh mu kuzigama amashanyarazi ku mwaka- na PUE yagabanutse kuva kuri 1,4 gushika munsi ya 1.25.

Ivyiza kuri: High- ibibanza vy’amakuru (uburemere bw’inguvu > 300 W/m2) canke gusubira gukora ama units ya kera ya CRAC (ntiyakeneye kwagura umwanya wo kwongereza ugukonjesha).

2. 30–50% Bitoyi, 40–60% Umuco: Bika Ikibanza c'Amakuru y'Ibarabara

Ikibanza c'igorofa y'amakuru ni ikintu gizimvye - n'umurongo wa kera- ibikoresho vy'ivyuma vy'ivyuma. MHEs' zose -aluminum igorotse- Tube + imiterere y'ivyuma ihuriweho ikuraho ibipande vy'umuringa vyinshi n'ibihengeri vy'amabuye bipfutse.

Ku muyaga 100 kW- Igishushanyo:

Igiciro: MCHEs zifata ~0.8 m3 (vs. 1.2–1.3 m3 ku tube- ku nzitizi), gushiramwo mu buryo bworoshe mu mpande canke mu mfuruka.

Uburemere: Ku ~80 kg (vs{1}} kg ku tube- ni vyiza ku bipande vya RAC vy’imbere-bigabanya umuzigo w’inyubako no kugabanya ibiciro vyo gushiramwo (nta gikoresho gikomeye co guterura gikenewe).

3. 50–70% Uburebure Buke: Amategeko y'Ibintu n'Ibidukikije

Ivyo bikoresho nka R410A birazimvye kandi biratunganirizwa (bishimira F{1}} Itegeko ry’Inyigisho n’UbushinwaIbara ry'icatsi kibisi n'iry'agaciro - Igenzura ry'Isuzuma ry'Ivyiyumviro vy'Ibigo). MHEs' umubare mutoyi w'imirongo (1/3–1/2 uwo muyoboro{{5}ban) ugabanya ivya nkenerwa:

Uburyo bwa 100 kW bukoresheje R410A bukeneye gusa 2.5–3.5 kg y’ifiriji (vs{4}}–10 kg ku tube-

Ivyiyumviro bikeyi (40% bike kuruta tube- hakoreshejwe imitwe y’imitwe) bisobanura ingorane zo mu bidukikije ziri hasi kandi nta n’imwe itwara firigo.

4. Uguhangana n’uguhungabana & 10.000-Hour MTBF: Gumana ARACs ziriyo 24/7

Ivyumba vy'amakuru bikoresha ata guhagarara - kandi igihe co guhagarara ni ikintu gikomeye. Umugezi wa kera- ibikoresho vy'ivyuma bita kare bitewe n'umuringa-aluminium fulvanic, ariko MHEs zubatswe kugira ngo zibeho:

Igishushanyo c'imiterere: Guca ibibatsi kurakuraho "-aluminum" (ikintu gikomeye gitera ubumara).

Ivyuma vy’ivyuma: Ivyuma canke ivyuma vy’umunyu (20–50 μm) bituma umunyu udashobora gutera umunyu kuva ku masaha 500 gushika ku masaha arenga 1500.

Ico vyavuyemwo? MTBF (Igihe c’Igihe hagati y’Imigera) igera ku masaha 10.000- Ni kabiri y’ivyo mu nzira- amasaha 5.000–6.000). Gusana gatoyi=igihe co guhagarara neza ku kibanza cawe c’amakuru.

Ivyiyumviro vy'ubuhinga bw'ubuhinga: Gukora MHEs Urakoze ku CRAC yawe

MHEs si "drop-in" isubirizwa-ikeneye guhindura kugira ngo ihure n'ivyo RACs zikeneye. Ehe ingene tubitunganya neza ku bibanza vy'amakuru:

1. Igishushanyo c'Ivyiyumviro vy'Ivyiyumviro vy'Inguvu n'Urusaku ruto

Multi- imirongo: Server iratera ku murango no kugwa mw’ijoro. MHEs zikoresha imirongo 2–4 y’uruja n’uruza, zifatanijwe n’ivyuma vy’ivyuma vy’ubuhinga bwa none, kugira ngo bihindure uruja n’uruza rw’amazi: ubushobozi bwuzuye bw’isonga, ubushobozi bw’igice c’ibinogo. Ivyo birinda "- ubukene" butera ivyago bimwe bimwe - Guca.

Amababa y'iherezo: Ibibanza vy’amakuru bikeneye urusaku rurengeye canke rungana na 60 dB (A). MHEs zikoresha ibiharuro vy’amapine y’imbere (1.8–2.2 mm) n’inyuma - abafana b’indege (1.5–2.0 m/s)- urusaku rwo ku 3–5 dB (A) vs.

2. (Ukurinda n'ugushigikirwa): Yubatswe ku bidukikije vy'Ikigo c'Amakuru

Inkungugu, umwotsi wa bateri ya UPS, n’ugucapura amazi ni ingorane zo hagati y’amakuru.

Ishingiro - irwanya - Gufata ububiko: Gutera imbere (5–10 μm) bituma habaho uguhuza, mu gihe igice co hejuru c’imbere (20–30 μm) kizibira ibinyamakuru vy’agahomerabunwa. Igerageza ryerekana ko rinanira umugese imyaka irenga 8 mu bibanza vy’amakuru.

Amazi-runda ku bipfukisho (ku mazi{{1}=CRACs): Imirongo ya MCHE (1–2 mm) irakunda gutera - rero twongerako:

100-mesh ibikoresho vy’ivyuma vy’ivyuma vy’ivyuma kugira ngo bibe ibihumanya.

Imirongo y'imirongo (1 mm inlet → 1.5 mm) kugira ngo ugabanye uruja n'uruza rw'amazi- ivyuma bitera urugero.

Ivyokurya-Biragrates z’urugero (nk’akarorero, aside ya polycarboxylic) kugira ngo haboneke ibihe vyo gusukura gushika ku mezi 12 (vs{4}} amezi ku tube{5}}).

3. Ugushiramwo CRAC bitagira ibara: Nta n’umwanda, Nta Leaks

MHEs zikora neza iyo zifatanijwe n'imirongo ya RAC-go sano ryose:

Uruhusha rwo guhuza: Amabati ya MCHE afise 15–20% y’ubushobozi bwo guhangana n’umuyaga kuruta tube-. Dukoresha hasi -sta - abafana b’umuriro (50–80 Pa) n’umuvuduko w’ikap kuri Les kuruta canke ungana na 1400 rpm kugira ngo tuzigame inguvu ata gutanga ubukonje.

Leak- inzitizi: Imitwe yinjijwe iciye mu giharuro c'interface kuva kuri 8–12 (tube- ku 2–4. Ibimenyetso bibiri vy’inyuma -kubika ibipfukisho biguma bivuza Inkomoko Bitari canke bingana na 1×10⁻⁻ Pa·m3/s (ku bigeragezo vy’ugusohoka kw’amazi)-

Igituma MCHEs ari kazoza k'Ibice vya RAC

Ku bibanza vy’amakuru, MHEs si ikintu ciza gusa co guhindura ubushuhe-bo ni uburyo bwo gutsinda intumbero z’ubuzima buramba, kugabanya ibiciro, no kuguma server zikora neza. Waba uriko wubaka ikibanza kinini- canke guhindura CRAC ya kera, MHEs zitanga ubushobozi, kuzigama umwanya, n’ugukomera ukeneye kuguma ufise ubushobozi bwo guhangana n’abandi.

Niteguye guhindura ibikoresho vyawe vya RAC? Raba ingene MHEs zishobora kugabanya PUE yawe no kwongereza ubushobozi bw’ikigo cawe c’amakuru uno musi.

Imisoro ishushe: imashini yo gusukura imashini yo gumesa imashini, imashini yo gusukura imashini y’ubuhinga bwo kwoza imashini, abagurisha ibintu, abagurisha, uruganda .
