Wanem samting i gutpela moa, wanpela 'open circuit' o wanpela 'closed circuit'?

 

 

Open Seket

 

 

Wanpela 'open circuit', we ol i save kolim tu olsem "direct-flow" o "open" 'cooling system', em i save kamap taim 'coolant' (planti taim wara) i pas wantaim 'atmosphere' taim em i raun.

 

 

As tingting bilong wok

 

Putim hat: Hat i save go long ol samting we i kol (olsem ol ensin o jenereta) i go long wara bilong mekim kol.

Evaporesen: Taim 'heat-laden coolant i go insait long 'radiator' (kondensa), em i save rausim hat i go insait long win long rot bilong 'forced convection' na 'natural convection'.

Kontektim: 'Coolant' i save senis hat wantaim win insait long 'radiator', we planti taim wara i save kamap olsem 'evaporation'.

Recirculation: Ol i save pamim kol wara i go bek long ikwipmen bilong kisim hat gen, na dispela i pinisim wok.

 

Ol bikpela gutpela samting

 

Gutpela Hat Disipesen Efisiens: Pasin bilong taitim win stret em i wanpela gutpela rot bilong rausim hat, na dispela i mekim na ol i ken rausim bikpela hat hariap.

Simpol Straksa: Dispela sistem em i isi tru, planti taim em i nidim wanpela pam, redieta, ol paip, na fen tasol.

Daunbilo Kost: Invesmen bilong ol ikwipmen na mentenens kos i liklik tru.

Mentenens we i isi moa: Bikos 'coolant' i pas wantaim win, ol mineral, ol pipia, na ol narapela samting insait long sistem inap long rausim isi tru long rot bilong 'blowdown', senisim wara, na ol narapela samting.

 

Ol bikpela hevi

 

Planti wara yusim: Dispela em i bikpela hevi tru bilong ol 'open circuit'. Kolsan i save go aut oltaim taim hat i wok long lus, na dispela i mekim na mak bilong wara i go daun, na i mas kisim fres wara oltaim.

Kwaliti bilong wara i bagarap: Long wanem, wara i save lus, ol mineral, sol, na ol pipia i save kamap planti moa. Dispela inap long kamapim ol 'scaling' na 'corrosion' insait long ol paip na redieta, na dispela inap long bagarapim tru 'heat dissipation efficiency' na 'lifespan' bilong sistem.

Polusen bilong win: 'Evaporated coolant' (moa yet taim ol i yusim 'antifreeze') inap long karim sampela samting i go insait long en, na dispela inap long bagarapim envairomen.

Nogut Anti-Fezing Capability: Long stopim ais long taim bilong kol, ol i mas putim bikpela hap bilong 'antifreeze' long 'coolant', na dispela i mekim pe bilong en i go antap tru.

Nois: Hai-spid fan rotesen i save kamapim bikpela nois.

 

Ol kain aplikesen

 

Ol i save yusim ol 'open circuit' long ol kain taim we ol i nidim bikpela 'heat dissipation efficiency', na wara yusim na mentenens kos i no nambawan samting.

Ol Ensin bilong Ka: Dispela em i nambawan aplikesen. Ol ensin bilong ol kar i save kamapim bikpela hat taim ol i wok, na wanpela 'open cooling system' i save rausim hat gut na tu i save kompensetim ol senis long level bilong wara long rot bilong 'coolant expansion' na 'contract'.

Marine Power Systems:Ol bikpela ensin bilong ol bikpela sipna ol jenereta i save yusim ol 'open cooling system', we ol i save yusim solwara olsem 'coolant', we i save go aut long ausait bilong sip o ol 'dedicated solwater radiators'.

Ol Pawa Plent: Sampela bikpela jenereta i save yusim ol 'open circuit', na ol i save yusim wara bilong ol 'cooling tower', wara, o raunwara long rausim hat.

 

Klos Seket

 

 

Wanpela 'closed circuit', ol i save kolim tu olsem "'klos" o "recirculating" 'cooling system', em i save kamap long rot bilong 'circulation' bilong 'coolant' (planti taim em i 'antifreeze' o 'special thermal oil') insait long wanpela 'closed system', na i no gat 'atmosphere' i go stret wantaim win.

 

 

As tingting bilong wok

Putim hat: 'Coolant' i save kisim hat insait long ikwipmen.

Indirect Heat Dissipation: Ol i save pamim 'heat-laden coolant i go long wanpela 'isolated heat exchanger' (planti taim ol i kolim "kula" o "kondensa").

Senis bilong Hat: Insait long 'heat exchanger', 'coolant' i save givim hat long wol bilong paip i go long narapela indipenden fluid (planti taim wara o win), na long dispela rot em i save kamap kol.

Recirculation: Ol i save pamim kol wara i go bek long ikwipmen bilong kisim hat gen, na dispela i pinisim wok.

Ol bikpela gutpela samting

Noken yusim wara: 'Coolant' i save raun insait long wanpela 'closed system', na klostu i no gat 'evaporation loss', na i no save yusim wara.

Gutpela Wara Kwaliti: Bikos i no gat wara i save 'evaporate', 'concentration' na 'composition' bilong 'coolant' inap long stap wankain longpela taim, na dispela i save stretim ol hevi bilong 'scaling' na 'corrosion'.

Strongpela Anti-Fezing Capability: Long rot bilong bosim gut mak bilong 'coolant' (olsem, mak bilong 'ethylene glycol'), ol inap long mekim ol samting bilong pasim ais long -20 digri i go inap long -50 digri o liklik moa, na dispela inap long stretim ol ples we i kol nogut tru.

Em i no bagarapim envairomen: Wanpela sistem we i pas olgeta i stopim 'coolant' long pairap na lik, na dispela i mekim em i no bagarapim envairomen.

Liklik Nois: Ol sistem we i pas i save yusim ol pam we i no gat noisnaol 'heat exchanger' na i no ol bikpela 'fan', na dispela i mekim nois bilong wok i go daun.

Ol bikpela hevi 

 

Heat Dissipation Efficiency i no bikpela tumas: Taim yumi skelim wantaim 'direct air contact', 'indirect heat exchange' long ol wol bilong paip em i no gutpela tumas.

Kompleks Sistem: Ol sistem we i pas i nidim sampela moa samting olsem ol 'heat exchanger', ol 'expansion tank', ol 'safety valve', na ol 'bypass valve', na dispela i mekim na straksa bilong en i hat liklik.

Kost i antap moa: Invesmen bilong namba wan ikwipmen, kos bilong 'coolant', na kos bilong mentenens i save antap moa long ol 'open system'.

Ol Bikpela Mentenens Rikwaemen: Taim kwaliti bilong wara i stap gut, 'coolant' yet i gat liklik sevis laip (planti taim 2-5 yia) na i mas senis oltaim. Na tu, ol pipia i ken stap yet insait long 'heat exchanger' na i mas klinim long olgeta taim.

Ol kain aplikesen

Ol 'closed circuit' em ol gutpela rot bilong yusim long ol samting we i gat strongpela lo long ol wara risos, kwaliti bilong wara, wok bilong daunim ais, na nois bilong wok.

Ol Data Senta: Ol IT ikwipmen olsem ol 'server' na 'switch' i save kamapim hat we ol i mas bosim gut. Ol 'closed cooling system' i save givim gutpela na gutpela 'cooling' na i no nidim wara, na dispela i mekim ol i kamap nambawan samting bilong ol data senta.

Precision Electronics: Ol indastrial kontrol kompyuta, ol medikel divais, ol tes instramen, na ol narapela samting, i nidim gutpela tempereja bilong wok long mekim wok i stret na i ken wok gut.

Ol samting bilong ami: Ol tenk, ol 'armored vehicles', ol ensin bilong balus, na ol narapela samting, i save wok long ol ples we i gat planti hevi, na ol 'closed cooling systems' i save givim gutpela proteksen long taim bilong ais na 'corrosion'.

Ol bikpela bilding: Long lukautim wara na lukautim envairomen, ol i wok long yusim ol 'closed-circuit wara sistem insait long ol sentral ea kondisen sistem bilong ol bikpela bilding bilong nau.
