Congratulation for running such a good and informative channel.I would like to correct in inverter AC compressor motor is not DC but it a 3 phase AC Motor.Speed of the compressor is controlled using a VFD(Variable frequency drive ) which is inbuilt in the inverter card of the devicer.
Yes sir you are right I agree with you . Lekin sir agr 15 tan ya 20 tan ka inverter compressor ho to wo bhi DC volt se chlega .???As vrv vrf machine me bhi inverter comp hota h jo kafi high tr me hote hai.
inveter ac me bldc compressor ko drive karne ko kafi complicated electronics hota hai(personally belonging to electronics field bought a non-inv ac), even a small fault se ac chalehga nahi, 24deg inv aur non-inv me same hi hota hai,poer consumtion me jaya fark nahi hoga agar ek room ko samjho 5000w lagta hai dono ac utna hi power consume karenge.
Thanks for such a helpful video. but I have a question that ;ac power supply is more convenient to control compressor motor because as per formula: N=120F/P...N=speed,F=frequency,P=number of poles......which means speed of compressor motor is directly proportional to frequency....then why we are choosing DC power supply to control the speed of compressor ?what is the specific reason behind it???? I am an electrical technician,now am learning HVAC by referring your videos.I am expecting that you will clear my doubt....Thank you
Sir, 1 baar ye video bnaiye ki kon sa ac kitna flow krta h, kitna lmba piping ho skta h, kitna jgh pe pipe fold ho skta h, kon sa ac kha lgana chahiye Pleass sir is topic pr 1 video bnaiye
Agar sir inverter ac me room child hone par rpm 1000 ya 1500 ke karib ho jaye hai to discharge pipe pe ya indoor unit pe ice kyo nahi hamari ,jaise ki humare non inverter model me agar pressure Kam ho jaye to ice ka problem face karna padata hai
I am very thankful ! for you sir all the video of VRV /VRF very use full for us. Please make a video for three phase to three phase and single phase to three phase drive. Thankyou Chandan Kumar DAIKIN SERVICE RANCHI JHARKHAND.
Sir I am a technician of DAIKIN AC in RANCHI JHARKHAND. sir please I have a question , That is ,In inverter ac we use, u call ''DC brush less motor'' but in inverter drives convert AC-DC-AC we get three phase AC. How we run a DC motor in AC three phase. Please clear the question sir.
[09/06, 10:12 am] dacvishal: Sir mere do room mei 5200 watt cooling capacity ka AC lag raha hai. Voltas wala room 25% chota hai. Same floor and same direction mei hai. [09/06, 10:12 am] dacvishal: Service center says that all the parameters are correct and AC is working perfectly. [09/06, 10:12 am] dacvishal: Voltas 40% less cooling karta hai. [09/06, 10:12 am] dacvishal: It is 1.5 ton inverter AC and reaches til12.5 ampere. [09/06, 10:12 am] dacvishal: Mera second ac (fixed speed reconnect brand) isse purana hai and 40% faster cooling hai. [09/06, 10:12 am] dacvishal: Kuch outside technician kah rahe hai ki zyada ampere le raha hai. [09/06, 10:12 am] dacvishal: Mera question hai ki kya inverter AC same cooling watt hone par bhi less cooling karta hai?
Sir IAM Chandan Kumar From Delhi b Sir mughe janana hai ki kiss bhi model ka inverter split AC me hum esaly kese pump down karenge Jess hum normal AC me karte hai wese ya koi or tarika hai Plz comment Kare sir
Thanks you sir for such a informational channel , We are going from nothing to something in RAC because of ur guidance... My question is that whenever there chnage in RPM is there change in suction pressure too?? Means at peak load hence at high RPM is suction pressure is more and at less load or half load is suction pressure is low ??? Please sir help
@@girishshinde sir please mere deep questions ka answer jarur de. अगर ac के Compressor me Oil डालना (change करना ) हो तो कैसे डाले? और कितना डालना चाहिए. क्योंकि गैस निकल जाने पर Oil bhahar निकल जाता है. या ac का ऑइल चेंज करना हो तो कैसे करें? और कब करे? अगर कंपनी ने कहा है कि मैक्सिमम 15 फीट तक height तक indoor and outdoor unit ac ज्यादा से ज्यादा हो तो एक्सट्रा गैस भरने की जरूरत नहीं इसका मतलब कंपनी ने उसके हिसाब से गैस ज्यादा भरी होगी अगर 3 feet pipe hi इस्तेमाल हुआ तो हमको गैस कम कर देनी चाहिए Compressor से क्योंकि 12 feet एक्सट्रा गैस भरी गए कंपनी की तरफ से? ताकि काम चल जाए हर हालात में? 12 feet ke हिसाब से हम 250 से 300 ग्राम गैस कम कर de. ताकि Compressor km electricity use करे? Amp km ले? क्योंकि कंपनी तो default पे manufature करती है Agar outdoor ऊपर है indoor नीचे लगा हुआ है तो क्या Compressor का ऑइल indoor मे चला जाता है? Compressor जल्दी खराब होता है? मैंने एक जगह पढ़ा था की अगर indoor unit नीचे लगा हुआ है तो maximum height 15feet से घटकर 10feet रखे.
Sir DC current me fricvancy ak jesy hoti he or compressor ki speed fricvancy se control kese hoti or yadi DC use hota he to 3 thimbal kyo hote he compressor me DC ko to ± ki jarurat hoti he pls. Reply
Inverter AC me agae 16°C temperature set karde (jo full garmi me possible nahi h ana) to wo counties full speed n full RPM pe run karega. To power save hagi kya sir. Plz reply ??
Sir ky hm invertor ac ka compressor direct chle skte hai agr pcb khrab ho or compressor check krma ho to kese kre check resistance same huye fir b khrab hai compressor to kese confirm fault milega
In digital scroll unloders are used for capacity controll by using digital controls but speed of compressor remain constant, in inverter scroll capacity of system control by controlling speed of compressor
Sir Main Ek bluestar AC main 2ton ka compressor dala hai gmcc Jiski main gas charging Ki Hai discard standing pressure 180 discharge pressure 300 Empire 12 suction pressure 30 or gas badhane par compressor ampere barabar band ho ja raha hai batao sir Main Kya Karoon Kya Baat Hai

Good information sir. सर, मैं HVAC प्रोजेक्ट सुपरवाइजर हु, और अपने फील्ड मे कुछ खास रोल नही है मेरा। ऐसा क्या कोर्स करे ताकि HVAC में डिजाइन इंजीनियर बन सके। वैसे मैं डिप्लोमा एलेक्ट्रिकल हूं। थैंक यू
Hats off sir,such a nice way you explain, thank you so much.i am looking for books written by you. Pls guide me to buy books on a/c system, from Mumbai.
