Sir your videos are really awesome only one thing that iam requesting you add real image photo of chiller or something which you are explaining... This is very useful for freshers to understand quickly with real site photos of that topic which your explaining. Thanks
you have mentioned the refrigerant out temperature as 50F from the evaporator. But, the heat exchange in the evaporator is latent heat transfer, so temperature remain constant. Or is it that the refrigerant enters the compressor inlet as superheated?
sir, is there any seperator installed between the inlet and outlet valve? If not, then I think the inlet high temp (12deg) water will mix with the outlet low temp (7deg) water and therefore the mixture of these two will rise the final outlet temp T (7
No separators are installed, water comes with high velocity from inlet and moves forward due to pump pressure it can not come back it has to move forward and it came out from outlet
Sir meri aapse request hai Aap ek video hmare ac technician bhai log ke liye banaye please 3 phase duct table ac me phase ulta aa rh ho or out on ho to kaise pta lagaye ki phase ulta hai Aapse meri request hai aap iss par ek video bna ke share kare hm sab log ke liye. 🙏🙏 I'm vikas from Lucknow u.p
1)Anti freeze work to control temp of water based on temp set pint 5 c 2)Air vent to remove the air from the water coming to the shell 3)condenser tube size 1/2'' to 3/4'' 4) Grove to control the flow and improve the efficiency of heat exchange in the eveporater
Liquid refrigerant ki density jada hoti hai tho vo niche hota hai vapour hone ke baad halka hota hai aur sirf vapor upar jata hai compressor main, liquid nicje hi rehta hai

1)Dx-direct expansion valve
2)standred temp is 12c to 7 c
3)baffle work to hold the refrigerant pipe and flow of water direction.
4)pressure drop difference of water in and is 0.5 c
A) DX full form =Dry Expansions
b) chiller water inlet 12 °C outlet 7°C
c) Biffle ka kam sound or vibration ko km krne ke kiye
Correct
Excellent vedeo sir.. really very helpful..to understand. Concept properly. Thanks you so much sir
Welcome
Thank you very much ,this is what i requested u in last videos. 👍
Yes
Sir ji apki videos se hame bahut experience milta hai. Plz VRV ya VRF system me konse faults aate hai or unki remedy ka video banaye plz thanks
Good video sirji
Thanks
1) chilli inlet ref - 4.4°c outlet ref 10 °c
2) anty freeze T ka kam hai chiller ka water temperature ko maintenance karna or water ka volume barne ke waja se chiller ko cracks hone se bachana
3) vant ka kam hai chiller ke inside me jo air rahta hai use nikalne ke liye use kiya jata hai
Sir your every videos are excellent and easy to understand please upload chiller maintenance video.
Superb explain wow sir love it
Thank you sir making this video
It's very helpful for us
1)DX= Dry Expansion
2) water in - 12°c out - 7°c
3)biffle kam water ka pressure ko kam karna or vibration ko rokhna
Great work.. Detailed video.. ❤️👍👍
Gud working.. 👍👍👍
Thanks
Sir good morning .Package AC ka electrical components or circuit wiring k visay m v video banaiye please..aap achha samjhate h...🙏🙏
