Closed-circuit evaporative cooler dahna tur kaihhruaina kimchang.

A closed-Circuit evaporative cooler hi industrial, commercial, leh HVAC system-a hman lar tak cooling device chhanchhuahna tha tak leh chakna pe thei tak a ni. Tui leh boruak inkara heat exchange hmangin tui kal vel chu a duh ang temperature-ah a ti lum a, chutih rualin ramdang thil luh a veng bawk. Installation dik tak neih hi long-term, stable operation neih theihna turin a pawimawh hle. He article hian closed-circuit evaporative cooler atana installation step leh fimkhur dan tur a tarlang a.

 

 

21 a ni. Pre-Installation buatsaih dan tur .

Install hmain a hnuaia inbuatsaihna te hi a ngai a ni:

Site thlan dan: Cooler chu well-thli tleh tur a awm loh nan obstruction atanga hla takah dah tur a ni. Maintenance atan (a tlangpuiin meter 1 aia tam emaw, a tlukpui emaw) clearance tam tak awm theihna tur leh ni êng direct emaw, heat sources hnaih lohna emaw awm lo turin a tha.

Foundation Inspection: Equipment siamtuin technical specification a pek hmangin, installation foundation-a load-bearing capacity (a tlangpuiin concrete foundation thickness nei 150 mm aia tam emaw, a tlukpui emaw) chu nemnghet la, levelness error chu 3 mm/m aia tlem emaw, a tlukpui emaw a nih theih nan.

Thil hmanrua enfiah: Unpacking leh pawm a nih laiin cooler model, accessory list, leh a lan dan te chu finfiah rawh. Fan, heat exchange tube bundle, leh water tank te ang chi component te chu integrity a awm leh awm loh enfiah thin ang che. Pipeline Pre-Planning: Pre-System dang nena inzawmna nei lo turin circulating water inlet leh outlet pipe, feed water pipe, leh drain pipe te routing design rawh.

 

II a ni. Main installation step hrang hrang .
1. Thil hmanrua dahna tur .
Lifting equipment (forklift emaw crane ang chi) hmangin cooler chu hmun ruat saah awlsam takin chawi la, heat exchange tube bundle leh electrical components te humhim turin fimkhur rawh.
Anchor bolt emaw washers emaw chu hmanrua chu level leh vertical (vertical deviation 1/1000 aia tlem emaw, a tlukpui emaw) a nih leh nih loh enfiah turin siamrem rawh.
2. Pipeline hmanga inzawmna .

Circulating Water Pipeline: Tui luhna chu system return pipe-ah connect la, tui chhuahna chu tui supply pipe-ah connect rawh. AY-Type filter hi cooler chhunga bawlhhlawh lut tur ven nan a tha hle. Pipeline-ah hian insulated a awm tur a ni (ambient temperature a hniam chuan), vibration transmission tihtlem nan flexible joint hman tur a ni.

Feed Water Pipeline: Feed water tank emaw automatic feed water device emaw nen inzawm la, a tlangpuiin float valve emaw pressure sensor emaw hmangin tui level control tur a ni.

Drainage Pipeline: Drainage emaw recovery system emaw nena inzawm a, drainage awlsam tak a awm theih nan. 3. Electrical installation
Power cable (a tlangpuiin 380V/three-phase) te chu electrical drawing angin connect rawh. Ground wire chu ground grid (ground resistance 4Ω aia tlem emaw, a tlukpui emaw) nen a inzawm tlat tur a ni.
Fan motor leh control cabinet wiring hi professional electrician-in a tih tur a ni a, chu chuan phase sequence dik tak a enfiah tur a ni (reversed phase-te hian fan malfunction a thlen thei).
4. Tui hmanga Commission kalpui dan tur .
Tui tank chu tui thianghlim tak, a level tarlan angin (a tlangpuiin a volume zawng zawng 2/3) ah dah la, pipe te chu leak a awm leh awm loh enfiah rawh.
Water pump leh fan te chu manual-in start la, water flow direction leh air volume en la, zawi zawiin designed parameters-ah siamrem rawh.
 

iii a ni. Fimkhurna pawimawh tak tak .
Safety Operation: Install lai hian invenna hmanrua (gloves leh goggles ang chi) vuah la, a san zawnga hnathawh laiin safety belt vuah bawk ang che.
Anti-Freeze Measures: Khawsik laiah chuan pipe leh tui tank te chu paih chhuak la, thlasik laiin system khar a nih chuan antifreeze dah la. Regular Maintenance: Install zawhah tui pH (7-8.5 tling) leh conductivity enfiah turin darkar 72 chhung atan darkar 72 chhung continuous monitoring neih a tha. Heat exchange tube leh packing te hi tihfai reng tur a ni.

Noise Control: Noise hi ngaihtuahawm a nih chuan fan outlet-ah muffler dah theih a ni a, fan speed pawh a inthlak thei bawk.

 

iv. pawm leh thawn chhuah .

Install zawhah a hnuaia acceptance test te hi a ngai a ni.

Performance Test: Outlet water temperature hian design mamawh a phuhruk em tih finfiah rawh (a tlangpuiin wet-bulb temperature aiin 3{{1}5 5℃in) a ni.

Safety Test: Electrical insulation ( 1MΩ aia tam emaw, a tlukpui emaw) leh emergency shutdown function a hnathawh dan tur enfiah.

Document Delivery: Equipment Manual, Operating Instructions, leh Warranty Card te pe la, user training pe bawk ang che.

Heng step hmang hian closed-Loop evaporative cooler chu efficient operation-ah dah theih a ni a, hei hian a hmangtute tan stable, energy-saving cooling solution a pe thei a ni. Installation chhunga siamtute thupek leh industry standard zawm tlat chuan hmanrua dam chhung a ti rei thei a, failure rate pawh a ti tlem thei bawk.
