Thankful professor for your efforts to teach the easiest way to get well knowledge of new type of a c system. Appreciate 💐💐💐💐💐👍👌🙏

[@shawncell1247]

thank you so much, for taking the time to explain this to me

[@ljs5757]

Really a fantastic great graphics the only problem I have is your cursor disappears into the white background perhaps you could make your cursor black or a darker color circle instead of being yellow maybe being black or something like that I'm having trouble following the cursor

[@rampyxl6812]

this is wonderful thank you so much sir

[@ProfessorPentane]

You are most welcome

Thanks! Help so much while finding the clogged TXV on my Volvo just replace a one 6 month ago

Hi if TXV is stuck open low side has more than enough free on, so why is it not cooling. I know it is an stupid question but could not find out answer. Pls help me

[@CWK090]

Cooling comes from Freon (actually "refrigerant") changing state from liquid to a vapor in the evaporator not simply the volume of refrigerant. Pushing too much liquid refrigerant through the evaporator causes liquid refrigerant to exit the evaporator. No evaporation-no cooling. A bigger concern with liquid refrigerant leaving the evaporator in a TXV system is slugging the compressor.

26 : 07 and the condensor fan cooling it further bringing the temperature down and taking pressure down

Wonderful

Wonderful.

Prof can you comment on what the H-valve is fully restricted, the variable displacement compressor is working and the high pressure line to the H-valve is cold to touch? Kindly comment of what may be happening.

[@abdul-kabiralegbe5660]

I'm not the Prof, but how do you ascertain the H-valve is fully restricted? I'd expect the High pressure line to be cold when the H-valve is stuck OPEN.
Edit: On second thought, maybe there's a leak in the High pressure line the same way a spray can gets cold when you press the nozzle to let the contents escape and evaporate.
Please endeavour to respond as I'm trying to learn here too.
Thanks.

My best guess would be either a leak before the h valve or the control solenoid valve on the compressor (variable displacement compressor) is bad.

looking for info on 1968 ltd borham compressor has no pressure . looks like a york but it is not . checking all your videos for more information . there is no info on the web about it. this channel may help me fix it
