Gutpela Kontrol Lojik na Eneji Efisiensi Optimaisesen bilong Fan na Sprei Sistem insait long Klosed-Circuit Cooling Towers
Insait long operesen sistem bilong ol indastrial kol sistem, kontrol bilong ol fan na sprei sistem insait long ol 'closed-circuit cooling towers' ol i ken kolim "intelligent core". Em i no wanpela isipela wok bilong kirapim ikwipmen, tasol em i wanpela 'dynamic balance system' we ol i wokim klostu long 'outlet temperature' bilong 'process fluid', we i mas painim gutpela rot namel long 'cooling efficiency', 'energy consumption' na 'water resource consumption'. As tingting bilong en em long kisim 'outlet temperature' bilong 'process fluid' olsem mak, na stretim gut mak bilong 'sensible heat exchange' na 'latent heat exchange' long rot bilong 'real-monitoring bilong ol envairomen paramita (olsem 'wet-bulb temperature', 'dry-bulb temperature', na 'windload' tempereja (insait long 'flow' bilong proses wara), na bihain winim wok bilong "go long mak bilong mekim kol wantaim liklik kos bilong yusim pawa".
Diskripsen bilong ol prodak
Long lukluk bilong 'heat exchange principle', wok bilong mekim kol bilong ol 'closed-circuit cooling towers em i wok bung bilong 'sensible heat exchange' na 'latent heat exchange'.
Proses fluid i save raun insait long 'closed coil', na hat i save go ausait long 'coil wall'; wok bung namel long sprei sistem na fan em long stretim mak bilong tupela rot bilong senisim hat long rot bilong senisim ol kondisen bilong senisim hat ausait long koil.
Taim 'ambient wet-bulb temperature i liklik (olsem long nait, long taim bilong kol o long taim bilong ren) na 'cooling load' i stap insait long lait, kontrol sistem bai givim namba wan ples long kirapimlow-eneji konsumsen mod- long dispela taim, i no gat nid long opim fan, sprei pam tasol i stat. Liklik wara bilong sprei i save spreim wankain long pes bilong koil na kamapim wanpela liklik na wankain wara film.
Bihain long wara film i pas wantaim win, 'natural evaporation' i save kamap, na bikpela hat insait long koil i save lus long rot bilong 'latent heat exchange'. Dispela bung bilong "evaporative cooling + natural ventilation" i save yusim tasol pawa bilong sprei pam (planti taim 1/5 i go inap 1/3 tasol bilong pawa bilong fan), we i wankain olsem "fri kol" na daunim tru pe bilong wok long taim bilong lait lod.
Long wankain taim, long abrusim lus bilong wara i ron bikos wara i tik tumas, sistem bai lukluk long wara bilong sprei long rot bilong wanpela 'flow sensor' na bosim long gutpela mak bilong "karamapim tasol koil na i no drip tumas", na dispela bai daunim moa yet wara risos wes.

Taim ol samting i kamap long envairomen i go nogut (olsem bikpela hat long taim bilong san, drai na hatpela weta) o wok bilong proses i go antap (olsem ful-lod operesen bilong ol prodaksen ikwipmen na inlet tempereja bilong proses fluid i go antap), 'natural evaporation' bilong wara bilong sprei tasol i no inap long inapim 'cooling demand'.
Long dispela taim, kontrol sistem bai statim 'synergistic enhancement mode' - pastaim isi isi long skruim spit bilong sprei pam long skruim sprei wara volium. Sapos 'outlet temperature' i antap yet long mak we ol i makim, bai ol i kirapim 'fan' hariap tru. Ol i ken kolim wok bilong fan olsem "kwalitativ senis swit" bilong mekim kol: long rot bilong fos konveksen, em i save putim bikpela hap win i go insait long taua, we i save ron hariap antap long pes bilong koil we wara film i karamapim.
Inkris long spit bilong ron bilong win i no save hariapim tasol 'evaporation rate' bilong wara film (latent heat exchange efficiency i go antap long 3-5 taim) tasol tu i save strongim tempereja difrens namel long win na coil wol (sensibol heat exchange efficiency i go antap long 1-2 taim). Aninit long tupela samting, strong bilong rausim hat bilong sistem i go antap long wanpela oda bilong mak.
Long dispela taim, fan na sprei pam i go insait long kodineted operesen stet. Tasol, gutpela samting bilong dispela moden kontrol sistem em olsem em i no larim tupela i wok long ful lod olgeta taim, tasol em i mekim "stepless adjustment" long rot bilong frikwensi konvesen teknoloji. Sapos yumi tingim 'fan' olsem eksampel, kontrol sistem bai stretim spit bilong 'fan' long 'frequency converter' bihainim 'deviation' namel long 'autlet temperature' bilong 'process fluid' na 'set value': sapos 'outlet temperature' i antap liklik tasol long 'set value', 'fan' bai wok long liklik spit bilong 30%-50%; sapos deviesen i go antap, bai spit i go antap isi isi i go long ful lod.
Eneji-seving ifek bilong dispela stretim rot em i bikpela tru - bikos pawa konsumsen bilong fan i wankain olsem kiub bilong spit bilong en, taim spit i go daun long 100% i go long 70%, pawa konsumsen i ken go daun long samting olsem 65%, we i daunim tru eneji west aninit long hap lod.
Gutpela kontrol bilong sprei sistem em i no inap long lusim 'frequency conversion' teknoloji na 'multi-pump combination strategy'. Long ol bikpela-skel klos-kuling taua, 2-3 sprei pam i save stap. Kontrol sistem bai bihainim tupela rot bilong "stretim namba + stretim spit" bihainim senis bilong lod: wanpela pam tasol i stat na wok long liklik spit aninit long liklik lod; wanpela ful-spid pam o tupela low-spid pam i stat aninit long namel lod; olgeta pam i save stat na wok long ful spit tasol aninit long bikpela lod.
Dispela bungim stretim i no abrusim tasol hevi bilong eneji konsumsen bilong "wanpela bikpela hos i pulim liklik kat" bilong wanpela bikpela pam tasol tu i mekim sistem i kamap gutpela moa long rot bilong multi-pump redundancy. Long wankain taim, sampela gutpela sistem bai putim tu wanpela 'bypass regulating valve' insait long 'spray pipeline'. Taim ples i hat tru (olsem long taim bilong ren) na 'evaporation efficiency' bilong wara film i go daun, 'bypass valve' bai op yet, na stiaim hap bilong wara bilong sprei i go bek long wara tenk na daunim volium bilong sprei.Dispela i no daunim tasol eneji konsumsen bilong wara pam tasol tu i stopim fomesen bilong skel long pes bilong koil long planti wara (skel bai mekim 'thermal resistance' i go antap na daunim 'cooling efficiency' long 10%-20%).

Antap long stretim strateji aninit long nomol lod, kontrol sistem i mas dil tu wantaim ol bikpela wok kondisen na ol 'fault' senario long mekim operesen i stap gut. Olsem, taim tempereja i go daun tru (olsem tempereja aninit long 0 digri long nait long taim bilong kol), bilong stopim bagarap long ol ikwipmen we i kamap long ais bilong wara film ausait long koil, kontrol sistem bai otomatik stopim sprei pam, kirapim fan na opim "anti-freezing heating device" long wankain taim. Long rot bilong fosim win i ron na lokal hat, tempereja bilong koil i stap antap long 5 digri; sapos fen i no wok gut (olsem 'motor overload', 'blade jamming'), sistem bai salim wanpela alam kwiktaim, apim wara bilong sprei long wankain taim, na opim "imejensi baipas paiplain" long putim hap bilong proses fluid i go insait long 'standby cooling circuit' bilong abrusim bikpela tempereja bilong proses. Na tu, sistem bai lukluk long gutpela bilong wara bilong sprei wara (olsem konduktiviti, pH veliu), na kirapim otomatik "sewage discharge na wara saplimen divais" taim wara kwaliti i go daun long lukim olsem wara film i wok gut na sevis laip bilong ikwipmen.
Diskripsen bilong ol prodak
Long lukluk bilong ol longpela taim operesen benefit, stretpela kontrol bilong ol fan na sprei sistem insait long ol 'closed-circuit cooling towers i no inap long daunim tasol eneji konsumsen na wara risos konsumsen tasol tu inap long skruim sevis laip bilong ol ikwipmen na daunim kos bilong mentenens. Folem ol data statistiks bilong ol indastri, taim yumi skelim wantaim 'fixed-speed stat-stop' mode, fan na sprei sistem wantaim 'frequency conversion control' inap long daunim pawa yusim long 30%-40% na wara risos yusim long 25%-35%. Long wankain taim, wok bilong klinim koil i go longpela moa long 2-3 taim, na mak bilong bagarap bilong ol ikwipmen i go daun moa long 50%. Dispela "eneji-seving, wara-seving na konsumsen-ridusing" operesen mode i no inapim tasol "grin na low-kabon" divelopmen nid bilong moden indastri tasol tu i bringim bikpela ekonomik benefit i go long ol entaprais, na i kamap wanpela bilong ol bikpela rot bilong apgredim ol indastriel kol sistem.
