q. Ahu running but not cooling what you check first ??👇 ans. check step by step . 1. check proper circulation water in chilled water pump . 2. check delta T temperature 3. check filter condition 4. check actuator properly open condition 5. check three zone damper . 6. air purjing at top floor or ahu cooling coil 7. clean staner (filter ) thank you dear HVAC team 🙏
Shootpin gues right call back mail pin got cut now nesma go happey for you guroped full got cuttin befor changed making now happey old grouped and new some gues and pin making bai monney hide not giveing under grvet seching ok some preastged all dids cas by mistacked one yrs set go after calling right lfted good now????%
Ji mmm apki sari vedios dawnload kr kr rakh raha hun bahut bahtareen tareeke se explain kiya ap ne allah apko or tarakki de is field mm bhi or dusre field mm bhi... Allah apki deen dunya dono bnaye .. nd apki communication skills bhi achhi.
Sir abhi winter season ara hai ek ahu ka actuator working nehin kar raha hai manually chal raha hai kya me VFD se frequency kam karke chilled water outline valve ko 50% ya 60% close karke chala sakta hoon aur ek baat sir ek OT me kya frequency kam kar sakte hai..
What is reson jab supply line ka damper 100% open karrahe h to motor high amp lekar trip hojaraha h aur jab damper 50% open karrahe h to motor ka normal apm araha h every mechanical equipment are ok
Sir chiller ka outlet temperature badh jaega Jo AHU ko jata hai Lekin usko 7 degree chahie agar vah 20 degree per Ho ko jaane lagega to kya problem ho sakti hai aur ham usko kaise sudharen plz reply kyuki ye question hmse pucha tha ek or question chiller ka saturation temperature kya hota hai please reply
Apke return line me chota sa actuater laga hoga ap isse pata kar lijiye ki konsi line return hai qki koi bhi unit ho uske return line me hi actuter lagya jata hai sukriya
विडियो लम्बी हो जाएगी कोई बात नहीं परफेक्ट होना चाहिए। AHU मोटर का फ्रिक्वेंसी 50 होता है। ठीक है लेकिन केवल प्राइमरी Motar हो 11kw का तो उसका फ्रिक्वेंसी कीतना रखेंगे। सर
ji apki frequency 50 hi rahegi frequency kam karne ke liye ya jyada karne ke liye VFD best hai ...chahe jo bhi electric part ho ...ha agar apke ahu me DPT laga hai jo...( differential pressure transducer ) apke duct ke pressure me set point diya jata hai ...maan lijiye 100 Pascal air pressure set hai...to jaise hi 100. achive hoga waise hi DPT vfd ko commond dega Aor uski frequency 50 se down ho jayegi .... apka bahoot sukriya ..ki apne support kiya ki vidio lambi jaane do 🙏
rahi baat ki kitne kilo watt ki moter hai apke ahu me ..to chahe moter 11 kw ho ya 20 frequency apki 50 hi rahegi ..aor use control apka DPT karega ..aap use Manuel bhi kam jyada kar sakte hai.....jarurat padne pe 🙏🙏
@@c4chiller9984 mai aapki sab vedios dekhta hu sir or kafi acchi vedios v banate hai ap , pr time mile tb theoretically hi AHU ke top 10 jo maintenance se related problems aati h uspr vedio bna dijiyega sir
@@c4chiller9984 sir ek video bana dijie water presser condenser in & out ..Evaporater Water presser in & out ..Condenser Refrigerant presser in & out .. Evaporater Refrigerant presser in & out
aor bhi ahu hote hai ...water apka waha se out ho jayega..aor agar waha bhi actuator off raha to ...sabse ooper line me ek by pass line hoti hai ...jo temperature maintan hone par open ho jati hai ...to water waha se out ho jata hai ..👉 cooling coil pe koi farak nahi padta ...dost 👍....but good question your
it's ok Atif ji ...ham apke liye jarur banayenge.full actuater pe vidio ....aor ha aap agar subscriber na bhi hote tab bhi ham apko batate .....bas ek request hai aap sabse🙏 ki agar aap sinior hai to always apne junior ki help karte rahna ...sukriya apka ..🙏
Sir aap ki videos dekh kar bahut kuch seekhne ko mila thanks for that Sir mera sawal hai ki kya jitna ton ka chiller hoga kya utna hi ton ka Ahu bhi hoga ya chiller aur ahu ke ton mein difference ho sakta hai isko thoda explain kar den
Ji bilkul agar hamare pass 500 tr ka chiller hai to۔۔ agar ham chache to 50 ton ke 10 ahu laga sakte hai۔۔ isse jyada hoga to chiller pe load ayega ۔۔۔yani ham barabar ahu to chiller kar sakte hai sukriya 💐🙏
@@c4chiller9984 Yani ke sir hum agar chiller 500 ton ka hai tou ahu ki capacity max 500 ton ki hogi usse Ziyada ton ka Ahu nahin laga sakte tou sir kya agar chiller ki capacity 500 ton hai tou usse kam ka ahu laga sakte hain Ya chiller aur ahu ki capacity equal hi honi chahiye ??
Kam capecity ka ahu laga sakte hai ham koi problem nahi hai 300 se 500 ton ke beech tak ..bas baat ye aati hai ki agar ham chiller ke hisab se ahu kam lagaye to hamara chiller under load ho jayega aor trip bhi ho jayega ...aor agar jyada laga diye to over load ho jayega
ji ha ....qki kuch cool karne ke liye kuch air to chaiyye na ...jo return air duct se ayegi ..agar aap return duct ko off kar denge to wo air kaha se lega .😋 aor cool kise karega ..... cooling hogi hi nhi ...aor apka ahu trip ho jayega damper off hone ki vajah se 👍
@@c4chiller9984 like what are the materials used in ahu room accoustic insulation , floor level what kind of concrete or shockwave pad is used..what playum duct etc I'n details
Ji Jaha bhi cooling system ki baat ayegi waha Hvac system hi rahega .. chahe Ahu ho ya chiller ya phir split ac .... 👉Bas differece itna hota hai ki chiller ko industrial me use karte hai jise ham centralize plant kahte।। hai ..
ahu inlet water temperature.. 7 to 9 digri celcius ahu out let temperature 11 to 13 digri celcius inlet water pressure minimum 2.9 kg outlet pressure....2.7 kg yaad rahe ki pressure kam ya jyada bhi ho sakta hai ...agar ahu hight pe ya ground floor pe hai to pressure kam ya jyada ho sakta haii👍
dost ... wo depend karta hai ki chiller ki capecity kitni hai ...usi hisab se compressor use kiye jate hai ... kisi me keval ek hi compressor hota hai ...kisi kisi me 2 ya 4
Running condition me 👉Agar apka ahu 1st floor ya ground floor pe hoga to uska pressure 3 kg se 5 kg ke beech me hoga ... Lekin jaise jaise ahu ki hight badhegi waise waise apke ahu ka pressure bhi kam hota jayega ...
