ji nahi .. moterize valve kisi sensor ke commond se nahi chalta .. ye direct hota hai ..yani ap off karoge to off hoga aor on karoge to on ho jayega. ....👉 lekin 2 way ya 3 way sensor ke commond se on ya off hote hai
Dear brother please tell me. Q.1 why use the hot gas bypass line in chiller machine. Q 2. Compressor Me chilled refrigerant chala jaye to kya hoga. Q 3. HVAC kis principal par Kam Karta hai.
Ans1: To remove hot gas in case condneser is not working properly and all gas is not fully Cooled. Ans2: Load on compressor will increase and it will lead to damage.
In 2 way valve case, supply of chilled water will stop to cooling coil and through vfd pump speed will goes to down but for example during 100%load 100 gpm suppling to ahu cooling coil but during achieved temp. 2 way valve will be closed then in line to be pressurized at that movement vfd start to work but 100 gpm water where will go? Can all 100 gpm will go to chiller or some amount will be by passed through decoupler?
yes ....after achieved temperature 2 way valve will be closed and then VFD frequency will be down according to required....👉 dcupler will be open when over pressure in inlet line ....its set pressure on dcupler 👍
jaise aap HVAC technician me gulf gaye hai to .. uska kaam ye hoga ki .. jaise ki koi maintanence me gaya hai 👉.. to waha pe jo bhi HVAC se related equipment rahega use mainten karna repairing karna hoga ..chahe wo split AC ho ya phir package unit ya chiller bhi ho sakta hai .... gas charging compressor replacement, brizzing ye sab HVAC technician ke under hi ata hai .. 👉baki agar kuch samjh me nahi aata to aap supervisor ya engineer se pooch sakte hai ... thank you 👍
dost ...actuator ko ham waha use karte hai jaha hame kisi bhi liquid ko control karna ho required ke hisab se 👉 ham apne HVAC System me actuator ko ahu ki outlet line me isliye lagate hai ki jab required ke hisab se cooling mil jaaye to ye dheere dheere water ko control karta rahe ...👍 I hope apko samjh me aa gaya hoga kuch aor doubt ho to aap pooch Lena thank you 👍
just for emergency kabhi agar actuator stuck ( jaam) ho jaye ya koi aor reason se open na ho to .👉..ham by pass line se water circulation aram se kar sakte hai ..
