Kuongororwa kweChillers

Muchina wekutonhodza unonzi chiller, inova chikamu chakakosha che data center air-conditioning system. Refrigerant inowanzova mvura, inonzi chiller. Kutonhodza kwe condenser kunoitika nekuchinjana kwekupisa uye kutonhora kwemvura yekupisa yakajairika, saka inonziwo unit inotonhodzwa nemvura. . Nzvimbo yedata ine kudiwa kukuru kwekukwanisa kutonhodza, uye kushanda nesimba kuri nani kunogona kuwanikwa nekusarudza unit ye ​​centrifugal. Chiller muchinyorwa chino chinoreva zvakananga unit ye ​​centrifugal.

Compressor yekutonhodza yecentrifugal icompressor ine speed inotenderera. Pombi yekusveta inopinza gasi rinofanira kumanikidzwa muimpeller inlet. Gasi rinotenderera nekumhanya kukuru neimpeller iri pasi pesimba reimpeller blades. Gasi rinoshanda, kumhanya kwegasi kunowedzerwa, uye rinozoburitswa kubva paimpeller, uye rozopinzwa mu diffuser chamber; sezvo gasi richibuda muimpeller, rine flow velocity yakakura, kuti rishandure chikamu ichi chespeed kuita pressure energy, A diffuser ine flow section yakakura zvishoma nezvishoma inoiswa kuti ishandure simba kuti iwedzere pressure yegasi; mushure mekunge gasi rakapararira raunganidzwa muvolute, rinopinda mucondenser yeyuniti kuti riwane condensation. Maitiro ari pamusoro apa icentrifuge. Nheyo yekudzvanya, sezvakaratidzwa muMufananidzo 1; Pamusoro pezvo, kuti ikwanise kudhonza uye kubvisa kutonhora, air conditioning system inosanganisira cooling water system uye cooled water system.

Kuumbwa kwechikamu cheCentrifugal

Kuumbwa kwechikamu che centrifugal ndekwekuti: kunosanganisira centrifugal compressor, evaporator, condenser, throttling orifice, mudziyo wekupa mafuta, control cabinet, nezvimwewo, sezvakaratidzwa muMufananidzo 2 neMufananidzo 3. Compressor inonyanya kuumbwa nekamuri rekusveta, impeller, diffuser, bend ne reflux device, uye volute.

Zvimiro zvechikamu checentrifugal
Hunhu hwechikamu chikuru che centrifuge ndeichi:
1. Kukwanisa kutonhora kwakakura. Sezvo kugona kudhonza kwecompressor yecentrifugal kusingakwanise kuva kudiki zvakanyanya, kugona kutonhora kwecompressor yecentrifugal yeyuniti imwe chete kwakakura. Chimiro chakabatana, huremu hushoma uye saizi diki, saka inogara munzvimbo diki. Pasi pekugona kutonhora kwakafanana, huremu hwecompressor yecentrifugal hunongova 1/5 kusvika 1/8 chete yehuremu hwecompressor yepiston, uye kana kugona kutonhora kwakakura, kunonyatsooneka.
2. Zvikamu zvisingapfeki zvakanyanya uye kuvimbika kwakanyanya. Macompressor eCentrifugal haapfeki zvakanyanya panguva yekushanda, saka anogara kwenguva refu uye ane mari shoma yekugadzirisa uye yekushandisa.
3. Chikamu chekudzvanya chiri mucompressor yecentrifugal chinofamba-famba, uye simba reradial rakaenzana, saka mashandiro acho akagadzikana, kudedera kudiki, uye hapana mudziyo wakakosha wekuderedza kudedera unodiwa.
4. Kugona kutonhora kunogona kugadziriswa nemutengo wakaderera. Macompressor eCentrifugal anogona kushandisa nzira dzakadai sekugadzirisa vane yekutungamira kugadzirisa simba mukati mechikamu chakati.
5. Zviri nyore kushandisa kudzvanya nekudzikisa zvinhu zvine matanho akawanda, uye zvinogona kuita kuti firiji imwe chete ishande zvakanaka uye ine tembiricha dzakawanda dzemvura inobuda.

Zvikanganiso Zvakajairika zveVaridzi veChillers

Muchina unotonhora uchasangana nematambudziko panguva yekuvaka nekushanda, uye kutadza kuchaitikawo panguva yekushanda. Kugadziriswa kwematambudziko aya nezvikanganiso zvine chekuita nekuchengetedzeka kwekushanda nekuchengetedza nzvimbo yedata. Izvi zvinotevera ndezvimwe zviitiko zvakaitika panguva yekuvakwa nekushanda kwemuchina unotonhora. Nzira dzakakodzera dzekugadzirisa neruzivo ndezvekutarisa chete.

Hapana kugadzirisa mutoro

【Chiitiko chedambudziko】
Nzvimbo yedata inofanira kugadzirisa dambudziko uye kuyedza kushandisa chiller, asi kuiswa kwemidziyo yemhepo inotonhodza hakusati kwapera, uye nzvimbo yacho hainawo mutoro unodiwa, saka basa rekuisa harigone kuitwa.
【kuongorora matambudziko】
Mushure mekunge kuiswa kwe centrifuge unit mu data center kwapera, terminal mu computer room haina kuiswa, chando chemvura chinobuda pa terminal chinovharika, uye chiller hachigone kugadziriswa. Mutoro wacho mudiki zvekuti hausvike pamuganho wakaderera we chiller, uye basa rekugadzirisa dambudziko harigone kuitwa. Kune rumwe rutivi, nekuti muchina unotonhora hauna kugadziriswa, server mu computer room huru haigone kuvhurwa nekumhanya, zvichiita denderedzwa risingaperi; pamusoro pezvo, panguva yekugadzirisa dambudziko, simba re dummy load rinodiwa rakakura, uye mashandiro acho achatora simba rakawanda; zvinhu zviri pamusoro apa zvinoita kuti cold machine debugging ive dambudziko.
【dambudziko ragadziriswa】
Shandisa nzira yekubvisa zvikanganiso pasina mutoro pakubvisa zvikanganiso. Maitiro aya ndeekushandisa zvizere simba rekuchinjana kwekupisa kweplate exchange, kuchinjana kutonhora kunogadzirwa ne evaporator yefiriji kuenda kudivi re condenser refiriji kuburikidza neplate exchange, uye kuchinjana kupisa kunoburitswa ne condenser yefiriji kudzokera kudivi re evaporator kuburikidza neplate exchange, kuitira kuti uwane kuenderana kwakakwana pakati pekugona kutonhora kwefiriji nemutoro wekupisa, uye shongwe yekutonhodza inongobvisa simba re shaft re compressor. Uchishandisa nzira iyi, zviri nyore kuwana bvunzo yakakwana yekushanda pasi pemitoro yakasiyana. Kutenderera kweseketi yemvura yekutsiva ne cold plate uye kugadzirisa kunoratidzwa muMufananidzo 4.

Matanho ekugadzirisa maitiro ehurongwa ndeaya anotevera:
1. Vhura vharuvhu yekupinda muchikamu chemuchina, uye iva nechokwadi chekuti nzira yemvura yakavhurwa kuti iite kutenderera kwemhepo kana terminal air conditioner isina kuiswa;

2. Vhura chiller chose parutivi rwemvura inotonhorera uye vharuvhu yekutsinhana plate kuti uve nechokwadi chekuti nzira yemvura yekutsinhana chiller neplate yakatsetseka, uye mvura inotonhora inodhonzwa nechiller uye kupisa kunodzoserwa nekutsinhana plate zvinogona kusanganiswa zvakanaka; vhura pombi yemvura inotonhorera uye gadzirisa frequency nemaoko kusvika ku45Hz kana kupfuura, uye uve nechokwadi chekuti kutenderera kwemvura kwakajairika;

3. Vhura vharuvhu yemvura inotonhodza yemuchina unotonhodza, vhura vharuvhu zvishoma parutivi rwemvura inotonhodza rwepaneru, wobva wabatidza pombi yemvura inotonhodza kuti mvura ifambe zvakanaka. Gadzirisa frequency yepombi kuita 41-45Hz; usatange wabatidza feni yetower inotonhodza;

4. Kana mvura inotonhora uye mvura inotonhorera yagara iripo, vhura chiller wobva waedza wega;

5. Tembiricha yemvura inotonhorera yemuchina wekutonhodza inotanga kukwira, uye mvura inotonhorera inotanga kutonhora;

6. Gadzirisa kugona kwekutamisa kupisa kwemuchina wekuchinjana kweplate zvichienderana nekuvhurwa kwevharuvhu yemvura inotonhorera yemuchina wekuchinjana kweplate, uye gadzirisa kuvhurwa kwevharuvhu pakati pe1/4 nekuvhurwa zvizere;

7. Batidza feni yeshongwe yekutonhodza zvishoma zvichienderana netembiricha yemvura inotonhodza, chero chipi zvacho chinogona kubvisa simba remubato wecompressor.

【Ruzivo】
Kuti kuderedze kushandiswa kwesimba uye kufunga nezvekutonhodza kwechisikigo, nzvimbo dzedata dzinowanzo gadzirwa nehunyanzvi hwekutonhodza shongwe yekutonhodza + plate replacement. Panguva yekukonzesa, kugona kwekuchinjana kwekupisa kweplate exchange kunogona kushandiswa kuwana kupisa kwakakwana kubva ku condenser yechiller sezvo mutoro wekupisa wekuisa chiller, kureva kuti, kutonhora kunokonzerwa nechiller kunotorwa neplate exchange.
Nheyo yekugadzirisa pasina mutoro ndeyekushandisa zvizere simba rekuchinjana kwekupisa kweplate exchange, kuchinjana kutonhora kunogadzirwa ne evaporator yefiriji kuenda kudivi re condenser refiriji kuburikidza neplate exchange, uye kuchinjana kupisa kunoburitswa ne condenser yefiriji kudzokera ku evaporator kuburikidza neplate exchange Side, kuitira kuti uwane kuenzana kwesimba rekutonhodza uye mutoro wekupisa wefiriji, nzira iyi iri nyore kushandisa uye iri nyore kushandisa.
