12:45 The Downward force ie Bulb force which try to open the valve and Upward forces ie Evaporating and spring force which try to close the valve.
Needle stand Balance Equation :
Bulb force = Spring force + Evaporating force.
Thankyou!

[@ankitanandvlogs]

Sir I am watching each and every video to clear all doubts and have proper understanding of refer system including my main purpose to clear MEO 4 exam. Thanks sir
Keep uploading such videos. Really helpful.

[@arvind9305]

Another great informative video. Amazing sir.

[@searainly]

Thank you brother! 👆

[@irshadansari7538]

Rest , very informative video.

[@najinkunnath6009]

Superb

[@rishabjaikumar4095]

Sir ,
when refrigerant come out of condenser and goes to thermostatic expansion valve it has high pressure and low temperature but you have mentioned high temperature and high pressure

[@searainly]

Please refer Basic Working principle of Refrigeration's lecture . Thankyou .stay connected 🙌

[@mithaleshkumar2486]

Very good lecture explain sir

[@kshitiz41]

Thank u sir

[@searainly]

Your welcome

[@jagdish99_sw]

Sir if evaporator load decreases, and there is extra flow of refrigerant in evaporator amd now needle valve is fully closed, so how this extra refrigerant is handled, ??

[@loneranger2366]

16:33 As per TS diagram temp of refrigerant remains constant as it absorbs only latent heat in Evaporator. But you are saying the temp will increase!!! And it will be sensed by feeler bulb.

[@sarthakraul361]

before txv it is HT HP and before evaporator it is LT LP ?? reason is flashing up liquid...can you say more about it sir???

[@shubhamyejare845]

Hii sir, my question is that initially how the sensing bulb senses the evaporator o/L ?
Because when the valve opens then oly the refrigerant is going to flow no and to open that valve bulb should sense...then initially how it sense when there is no flow

[@mukhtarahmad4293]

Best explain

[@artemiosycee1845]

English subtitles please to all of your videos☺️ please sir. Please

[@kusanavakaran430]

Wah sirji.

[@searainly]

🙌

[@brainstonm5570]

Sir y this pe is required? We this internal equliising line?

[@unknownman4684]

What is degree of superheat sir?

[@shashanksandy112]

The purpose of drier is to remove moisture, Sir then how it is possible for liquid refrigerant to enter TXV? And also please explain how does temperature outlet of condenser is high?

[@searainly]

HP HT vapour refrigerant enters into condenser.Constant temperature heat rejection (Latent heat rejection ) takes place inside the condenser it mean vapour refrigerant directly converted into liquid refrigerant at constant temperature. & that liquid refrigerant pth TXV.

[@searainly]

And then HP HT liquid refrigerant enters a constricted tube which is the expansion valve. Now similar to the convergent nozzle, the velocity of refrigerant increases which obviously lowers its pressure(Thats why TXV is also act as Pressure reducing valve) Since Temperature is directly related to pressure, the refrigerant’s temperature decreases. This process is a constant enthalpy process.
And other properties of expansion valve I already made video for d same.
Thank you!

[@shashanksandy112]

Thanks alot sir your videos are very much helpful and do make a video on jacket cooling water system.

[@searainly]

Yh sure brother I will cover this topic on my Marine line diagram lecture series.

[@vaibhavtandon3572]

@@searainly great explanation

[@irshadansari7538]

बहुत complicated कर दिया है आपने ।

[@irshadansari7538]

डायफ्रॉम होता है सर जी उच्चारण।

[@searainly]

Sorry my mistake 🙏

[@nawazsitam9732]

Sir how i join marine for refrigerarion and air condition .. I completed iti .what next ... Dont mine

[@searainly]

U may join Lateral Entry b. Tech course after completing your Mechanical/Electrical/Electronic Diploma course.

[@saqlainmahiwal3216]

sir aap kis company me placed hai?

You are speaking language not understandable ( wasted one). speak international language an English. Easily can understand and you reached short period.
