Panon Kaabeba so Ibaba na Temperatura na Danum ed Cooling Tower Outlet?

Say sankatageyan a limitasyon na panagpabetel na sakey a cooling tower et nadetermina ed temperatura na bombilya ed paway na ambetel, tansay andi-anggaan ya ambetel et imposibli. Say manunan pankakasakey na industriya et onia: say sankaabebaan ya temperatura na danum ed paway na sakey ya estandarten lukas a cooling tower et nayarin onasingger labat ed temperatura na bombilya ed paway na ambetel tan 3 anggad 5 degree.

 

Lapud limitasyon na istruktura na panagsalat na petang,sakey ya akasara ya cooling tower say sankatageyan ya temperatura to et ontagey na kaaruman ya 2 anggad 4 degree. Saray chiller, ice thermal storage system odino arum niran kagawaan ed panagpalamig so kaukolan ya i-deploy no nakaukolan so abeban temperatura na danum.

 

 

 

Say temperatura na bombilya ed paway na ambetel et sakey a kritikal a paraan pian nasukat so danum ed dagem tan say kapasidad na pangipaway na petang, ya midumaan ed temperatura na bombilya ya amagaan ya nanenengneng na totoo.

 

 

 

Diad ambetel iran agew na tiagew ya atagey so danum na dagem, say temperatura na wet-bulb et onasingger ed temperatura na kaliberliber, ya mamapakapuy ed heat rejection performance na cooling tower.

 

 

 

Diad amagan pasen tan maong so dagem to tan abeba so temperatura na bombilya, say inkaepektibo na pakaandi na petang et onaligwas a maong. No alaen so kondisyon na operasyon ed tiagew diad Bukig na Tsina bilang alimbawa: diad temperatura na dry-bulb ya 35℃tan wet-bulb temperature ya 27 degree, say teoretikal ya sankaabebaan ya temperatura na outlet na sakey ya conventional open cooling tower et manlapud 30℃anggad 32 degree.

 

 

Diad amagan Northwest China ya say temperatura na dry-bulb et onsabi ed 38℃bangta say temperatura na wet-bulb et 22℃labat, say danum ya ompaway et nayarin onlemew ya anggad 25℃–27 degree, ya mangipapanengneng na mapatnag ya pandumaan na temperatura.

 

 

 

 

Lukasan so counter-flow tancross-flow cooling towersso sankalaknaban ya inadapta iran modelo. Manmamatalek ira ed direktan pan-evaporation na danum tan dagem parad pakaandi na petang, ya mangiiter na sankatageyan ya heat exchange efficiency tan sankaabigan ya cooling limit.

 

 

 

Diad silong na sankaabigan ya kondisyon na full-load ya malinis so karga to, saray bentilador ya onkukurang ed sigpot a kapeles tan parepareho so panag-spray na danum, say teoretikal ya limitasyon na panagpabetel et 3℃ed tagey na temperatura na bombilya.

 

 

 

 

Diad praktikal iran aplikasyon na inhenyeriya, saray bengatla a singa say panag-scale on fills, nabawasan ya dagem na bentilador, ag-inkaparpareho na panagbunog na danum tan say short-circuiting na dagem ed loob na tori so mamawala na pakaandi na performance.

 

 

Kanian, say pangireserba na 5℃ya temperatura et mas maligen ya paraan na panagdesinyo. Dakel a pabrika so nalilingo ya manisia ya say danum et nayarin palemewen ed 20℃diad temperatura na kaliberliber ya 30℃bangta ag da iimanoen so wet-bulb constraints.

 

 

 

Saya so pansengegan na alablabas ya temperatura na operasyon tan saray alarma na sobran petang ed saray kagawaan ya atagey so temperatura to a singa saray air compressor, injection molding machines tan medium-frequency furnaces.

 

 

 

 

Saray akasara ya cooling tower et manguusar na sealed coil heat exchange, kanian say sirkulasyon ya cooling water et agbalot direktan makapitongtong ed dagem, ya mansiansian malinis tan anggapoy karutakan ya kalidad na danum. Onkana iratan ed saray senaryo ya walaan na istrikton kakaukolanen ed kalidad na danum kaiba lay panagtipon na enerhiya na photovoltaic, saray precision machine tools tan saray chemical reactor.

 

 

Balet, say ekstran thermal resistance manlapud metal coil walls et mamapaabeba ed cooling capacity da no ikompara ed saray lukas ya tori. Diad parehon kondisyon na wet-bulb, say temperatura na paway na sakey ya akasara ya tori et 2-4℃ya mas atagey nen say sakey ya lukas ya tori.

 

Diad kaliberliber ya walay 27℃ya temperatura na bombilya, say estandarten akasara ya cooling tower et makadampot labat na minimum ya temperatura na paway ya 32℃–34 degree. Say pangiyarum na auxiliary spray cooling tan pamarakep na airflow na bentilador et makapangibawas na temperature gap na ngalngalin 1 degree, balet ag to nin siansia naabot so limitasyon na cooling na saray open cooling tower.

 

 

Dakel ya manguusar so mankaukolan na abeban temperatura na cooling water, alimbawa 15℃anggad 20℃no panaoy ambetel, ya ag nagawaan na saray cooling tower labat.

 

Anggaman onlelereg so temperatura ed kaliberliber no panaoy ambetel, say dagem et walaan nin siansia na manunan wet-bulb temperature threshold, tan say evaporation cooling labat et ag makapalemew na danum ed leksab na sayan threshold.

 

Walay duaran posiblin solusyon: unona, mangiyan na plate heat exchanger ya ipares ed saray chiller parad segundaryon panagpalamig pian nabawasan so temperatura na danum; komadua, mangi-deploy na air-cooled chillers ya independente parad melag-scale ya abeban-pemperaturan proseso ya ag-ondepende ed saray cooling tower.

 

 

 

 

Say rotinan panmintina so direktan mandetermina ed aktual ya limitasyon na panagpabetel na saray cooling tower. Say fill clogging ya sengegan na limescale, slipping fan belts, akabaraan ya spray pipelines tan say pakaamper na bentilasyon na saray akapaliber ya babeng et nayarin mamaatagey ed aktual ya temperatura na outlet na 4℃anggad 8℃ya mas atagey nen say theoretical value.

 

Say regular a panaglinis tan pangisaliwan na saray kargaan, panag-inspeksion na bentilador tan pangekal na lutak ed leksab na tori so mamapawil ed orihinal a kapasidad na kagawaan ya mangibulos na petang, ya mamaapit ed temperatura na panag-operate ed adesinyoan a limitasyon na panagpabetel.

Diad sumaryo, saray cooling tower et manunan evaporative heat dissipation devices ya say sankatageyan ya kapasidad dan manpabetel et nasarag na lokal ya temperatura na bombilya. Say sankaabigan ya temperatura na paway parad saray lukas a tori et mipara ed temperatura na basaan-bombilya tan 3-5 degree, bangbalet parad saray akasara a tori et mipara ed temperatura na basaan-bombilya tan 5-9 degree.

 

 

 

No saray detalye na proseso et mankaukolan na temperatura na danum ya abeba nen say saya, kulang iray cooling tower labat, tan kaukolan ya idagdag so mekanikal ya kagawaan ed panagpalamig. Say pirmin panmintina ed inagew-agew tanpanaglinis ya abuloyan iray cooling towerpian tuloytuloy ya naabot so sankatageyan ya cooling performance da tan naseguro so ag-ontutundan stable ya operasyon na saray kagawaan ed industriya.
