Larim wanpela toksave
Ol samting bilong pasim ais long ol 'closed cooling towers'
Taim wanpela 'cooling tower' we i pas i wok long taim bilong kol, sapos yu no bihainim ol gutpela samting bilong pasim ais, dispela inap long kamapim ais na bruk. Moa yet, ais, bikpela na bruk bilong ol 'heat exchanger tubes' bai mekim ol ikwipmen i no inap wok gut.

Ol samting bilong daunim ais bilong 'Internal Circulation' (Insait long ol 'Heat Exchange Tubes')
(1) Putim 'antifreeze' long wara sistem we i raun long mak yu laikim. Luksave olsem 'cooling capacity' bai go daun liklik taim sistem i wok wantaim 'antifreeze'.
(2) Sapos ol kondisen bilong sistem i orait, yusim 'antifreeze' em i gutpela rot bilong lukautim yu long 'coil freezing'. Taim ol i no inap long yusim 'antifreeze', sistem i mas holim wanpela kain hat lod long wara i ron long en long lukim olsem tempereja bilong wara i ron aut long koil i antap long 7 digri.
(3) Long ol yunit we i save pas oltaim (olsem, ol i save wok long san na stop long nait), ol i ken putim wanpela 'internal bypass electric heater'. Long taim bilong pasim wok, 'bypass electric heater' i save givim hat i go long ol 'heat exchange tube' bilong 'closed cooling tower' bilong stopim ais
.(4) Long ol yunit we bai i no inap wok longpela taim,em i bikpela samting long rausim olgeta wara i raun long ol 'heat exchange tube'. Sapos yusa i no putim wanpela 'drain port', opim 'exhaust port' bilong 'cooling tower' we i pas wantaim taim yu rausim wara. Sapos ol kondisen i orait, yusim hai-presa win long rausim olgeta wara i stap insait long ol paip. Kipim 'exhaust valve' na 'drain valve' i op taim yu putim ol samting.
Ol samting bilong daunim ais bilong sprei wara sistem
(1) Putim wanpela anti-elektrik hita long wara tenk daunbilo. Taim yu putim lektrik hita, em i gutpela long putim ol narapela samting olsem wanpela 'liquid level switch' na wanpela 'temperature sensor', na putim otomatik kontrol long stopim lektrik hita long paia o hat tumas. Planti taim, ol i mas opim hita taim tempereja bilong sprei wara i go daun aninit long 4 digri, na pasim taim tempereja i go antap long 8 digri. Tempereja sensa i save salim ol signal i go long kontrol kebinet long bosim stat na stop bilong lektrik hita. Ol i save makim pawa bilong lektrik hita bihainim hamas wara i raun na temperaja bilong ples.
(2) Longpela taim bilong pasim, rausim olgeta wara i stap ausait, na holim 'drain valve' bilong wara tenk daunbilo na 'drain valve' bilong 'spray water pump' i op taim yu putim.
Ol samting yu mas lukaut long en taim yu wok long taim bilong kol
1) Rausim olgeta win long ol koil pastaim long kirapim;
(2) Oltaim sekim na rausim win insait long ol koil taim yu wok long stopim win long go insait long sistem;
(3) Mekim gut olsem ol 'cooling tower coils' i pulap long wara taim ol i wok;
(4) Kipim wara tenk daunbilo i no gat ol pipia na ol liklik hap samting long en bilong abrusim bagarap long 'mechanical seal' bilong 'spray water pump'.
Long taim bilong kol, ol i mas mekim ol samting bilong pasim ais long wara i raun na wara bilong sprei. Na tu, bikos long liklik tempereja bilong wet-bulb long taim bilong kol, trupela kol kapasiti bai winim mak bilong kol, olsem na em i gutpela long stretim tempereja bilong wara i raun long en.
Stretim Lod
I gat tupela rot bilong stretim lod: operesen bilong wara baipas paip na fan operesen kontrol.
(1) Taim planti 'cooling tower' i wok, sampela 'tower' i ken pas. Putim hat lod long liklik namba bilong ol taua long apim hat lod bilong ol, o stopim ol fan long apim tempereja bilong wara i kol na stopim ais.
(2) Operesen bilong Paip bilong Raun Wara Putim wanpela baipas valv o tripela-wei valv long inlet na autlet bilong wara bilong kol taua. Folem tempereja bilong wara i go insait na i go aut long 'cooling tower', 'temperature controller' i save bosim 'opening degree' bilong 'bypass valve' o 'three-way valve' long stretim 'circulating water inlet' temperaja long sait bilong lod. Taim hevi i liklik tumas, ron bilong wara bilong mekim kol i go long taua bilong mekim kol ol i no ken stopimbilong stopim 'heat exchanger' long kamap ais na bruk bikos long wara i no senis. Na tu, taim lod i liklik tumas na i gat sans long wara i ken kamap ais o wara bilong sprei, em i gutpela long bosim stat na stop bilong ol fan wantaim long stretim tempereja bilong wara bilong sistem.
(3) Fan Operesen Kontrol
Stretim tempereja bilong wara bilong 'cooling tower' long rot bilong bosim wok bilong 'fan'.
wanpela. Kirapim na stopim ol fen bihainim tempereja bilong wara i ron i go aut;
b. Mekim o daunim namba bilong ol 'operating fan' bihainim 'temperature' we ol i painimaut;
c. Yusim ol 'variable frequency motors' long stretim spit bilong fan.
