l'm from Indonesian you're best
This professor takes his time and teaches. I can retain the knowledge quicker, when it’s taught that way.
Wow! Thank you so much for your kind words! I love teaching, and it gets me motivated even more when I know I'm helping you guys out there! Thank you for watching!
To check if you have power at a solenoid you can also rest your amp meter on the magnet and see if it is drawing amps. Thank you for the video!
Thank you!!!
Well done, kept it simple and easy.
Good explanation.
I used to work with these compressors, Carrier model O5G 6 cylinders in motor coaches. They were belt driven by the bus engine.
When the unloader coil on a head. was electrically energized, those cylinders were unloaded.
Lots of guys were confused by this.
You could actually feel each side of the outer heads and sense a temperature difference from one side to the other. Low side, high side.
I would watch the needles on the gauges "jump" when the unloader went from energized to densrgized.
Yes, you are correct. A lot of guys get confused with the loading and unloading and with the pressures rising and falling as it loads and unloads. I am glad he liked the video. Thank you for watching!
Great explanation mate, I have a learning disability and that made sense to me, thank you so much
I'm glad you like the video and I am glad that it made sense to you! Keep watching the videos and maybe the other ones will help some more! Good luck out there!

Thank you for sharing your knowledge. You make great videos
Thank you so much! I really appreciate your comments, and I hope to make some more soon!
Thanks for the information. Every now and then I come across unloaders. I understand the concept of what their function is but was not sure how I would go about troubleshooting if I came across a bad unloader. Knowing how your pressures regulate unloaded and loaded helps especially when there are 3 or 4 unloaders on a comp. Constant cycling of the compressor would probably indicate that the unloaders aren't doing their job.
Yes, that could be an indication. You should check to see if the unloaders are unloading before the compressor shuts off. I mean it should be fully unloaded before it shuts off. Unloaders work great and it minimizes the constant starting up and shutting off of the compressor.
Omg its awesome its so easy to understand my teacher doesnot describe like this
Sir u r amazing.....no words to thanks u....I was looking for months to clear my concept about unloading and loading ...u make me clear in just few minutes....thanks a lot ....God bless u

Very nicely explained Sir thank you
Thank you and thank you for watching!
This is amazing! Very knowledgeable n good explanation! U r my great instructor 👍can u explain why compressor need pressure equalized ？please!
Thank you so much! Thank you for your compliments and thank you for watching. I am not sure what you mean when you say pressure equalized? I believe you are talking about the pipe that is normally connecting two compressors when they run tandem Lee like in a chiller? One of the reasons they do this is because of the oil. As the compressor runs, it will pump some of the oil out because it mixes in with the refrigerant. As the suction Gas comes back, the oil is mixed in with it, and it would collect in only one of the compressors, if we did not have this equalization pipe between the two compressors. I hope this answers your question!!! And again, thank you for watching!
Very instructive,thank you very much,God bless
Thank you!!!
Very well explained
Thank you!!! I am glad you liked it!!!

Thanks for the knowledge now i understand it helps
Good morning, I have a question for the technician, that after I disassembled the Carlyle 5h80-A194 compressor and replaced the new spare parts, namely the piston, ring, conroad, bearing conroad complete with 4 slave cylinders. After that, I tested running, but it looks like the compressor is not powered up, even 2 cylinders feel hot. I've tried opening the cylinder cover again and checking that the valve plate is installed correctly, the suction valve is in position. Then the test run again, the result is still the same. Even the capacity valve has been adjusted. clockwise or vice versa, but the compressor is still not powered. my question: can i be helped to find a solution so that the compressor can run normally and can cool down. notes. now i run compressor no two normal and cold. Thank you in advance
Thank you for the information.
I am glad I cold help!

I have watched a lot of technical teachers on compressors, on you tube. Some would talk and talk and include practical works and the more you try to learn from them, to mire confused you become. But in your case your explanation is very clear and easily understood. I'm a factory owner in west Africa. I handle heavy industrial and commercial equipments and have large stock from Copland, Carrier, Hitachi, Bitzer, Duareen etc. I build blasting units, cold storage facilities, as well as air Condition commercial and residential buildings. I would like to watch more of your videos, as well as share Ideas. Thanks.

Welcome
I understand the heat load determines if the loaders are energised or not. What are some ways this happens? Is it communication with a room thermostat? Is it recording discharge air and is trying to maintain set point? I’m sure there’s a lot of ways to control them, but what are the most common?
Thanks for the videos you are a great teacher
Very nice explanation sir and thanks
Had one small query that what if the external solenoid loaded/unloaded is not used for compressor and all pistons are working loaded and will cut off only when the room temp reaches the desire temp set point by the LP and HP cut out, will it work normal if we remove the solenoid in emergency can we make it direct in some situations.
Yes if your compressor is fully loaded when the solenoid is de-energized and you remove the solenoid, then the compressor will always be loaded and it will operate without any problems. that is ok. thank you for your question.
Good teacher I like his style
Thank you!!!! I am glad you liked it!!!!

Thanks my teacher
Thank you for watching!!!
Great video! When adding refrigerant to a system, the compressor should be loaded. Typically, on an 06 e/d Carlyle, should the unloaders be ran in or out to be loaded?
Yes, that is the only way to get the charge correct. To make sure the system is fully loaded. I don't know how your unloaders are set up but make sure that the unit is calling for full cooling so that the unloaders will be loaded. You will see that the pressures will change. The suction pressure will drop and discharge pressure will increase. Only then will you be able to get a charge correct. Hope this helps.
so inspiring sir!! how to apply basic course about hvac? i really want to learn more. thank you for sharing sir.
HI, I am so sorry I just saw your comment. If you go to my webpage you can see some of my courses and what I will have coming on soon. Thank you!!! airconacademy.com/courses-2/

احسنت very wonderful video
Thank you! I'm glad you like the video! Thank you for watching!
You are number one
Can you tell me about Air compressor have unloader but is the that unloader work at same this operation or just discharge the air out to surrounding when unloading time(start and stop the compressor)?
Thank you and I'm glad you like the video! Air compressors they load and unload to keep the electric motor from drawing high amperage. Every time an electric motor starts up it draws high amperage and that cost money in electricity. Plus it puts stress on the motor. So it is best to just unload the air compressor so that the air is not being compressed and being dumped out so that you don't have the start and stop on air compressors. I hope this helps and again thank you for watching!
thanks. very helpful!
