Excellent. Many people don't realize that compressors are cooled by the proper refrigerant charge, using that coolant on the return or suction line, to keep the compressor from overheating. Thus destroying the oil and parts within the hermetic or semi-hermetic compressor. Very well explained. Thank you for all of your superb videos.
Wow! So glad I found your channel this is so awesome!! I work in residential construction, not in the HVAC trade but lately have wanted to understand more about it, mostly because I wanted to install some ductless heat pumps, but I'm falling down a rabbit hole and it's great! Thanks for the education it is definitely improving me! So again thanks for that!
This was helpful. I wasn’t sure if the gas went to a liquid after the compressor. Makes sense though as heat will need to transfer into the outside air and gases do a good job transferring heat.
Hello Bryan Question, if you have r22 compressor and it is absolute can you replace it with R410 compressor remove compressor POE oil and replace it with mineral oil and charge it with R22 refrigerant will it work?
PLEASE HELP ME I bought a 1.5Ton 5Star inverter Ac 2days ago a installation team came for installation, they installed the indoor unit and the outdoor unit perfectly and Vaccum the system through the charging hose (service line) after Vaccum the closed the valve of Vaccum motor and turned the Vaccum motor off after this he turned the discharge line (liquid stop valve) for 5sec and turned it off to check leaks till this everything he did was perfectly right as the manual said but after this the manual said to Disconnect charging hose from gas stop valve's service port, then fully open liquid and gas stop valves. But instead he opened the discharge line completely and then started to disconnect charging hose from which the gauge was connected as soon as he started open the gas started to leak from the charging hose and he took almost 30sec to disconnect till than it was leaking and it stopped when it was disconnected and at last he fully opened the discharge line and now Im overthinking and living in fear that what was that gas was it the refrigerant or the compressor oil or it may have suck air inside the compressor or coils because it was vaccumed, it may have contaminated the refrigerant that May lead to BLAST (Explosion) OF COMPRESSOR NOW IM Living in fear that it may blast any time what should i do now Please help me
"Those are rare because you have a shaft coming out of the compressor" ..most cars on the road. Don't forget about MVAC. There might be more open drive compressors than hermetics, could the number of buildings and their AC and refirgeration units compared to vehicles.
it is a great video! Thanks! I just believe that a higher compression ratio means that the compressor is compressing the refrigerant vapor to a higher pressure, resulting in increased work done by the compressor and higher system temperatures.
I replaced my first compressor today in a rac. I had 0 clue what I was doing since I started commercial literally last week and I’m used to residential, my trainer made me replace the compressor on a rac and didn’t help out with anything just said “go do that.” Even though I made it open that I am very green and just learning so I don’t know what I’m exactly doing yet. Still made me do it with 0 tips or clues. I messed up on literally every step besides shutting off power and checking power. But he wouldn’t help me or walk me through it and he kept getting butthurt at me. I wanna learn this stuff but the guy training me is a pr*ck
what would be a bad compressor ratio? i had an r22 runing on my low side at 96 with a discharge pressure of 267. it was a new customer i dont know what the previous company did, lst company was their 5 years ago. i replaced the fan motor, cusotmer didnt want a new unit, so basically i made it clear to the customer that unit will not operate efficiently
Make so much since that the compressor can't turn the vapor to a liquid because if you're compressing somthing you're increasing heat and heat doesn't make liquid it just "create" more gas but the condenser coils are actually rejecting heat and changing the state.
I heard from someone that a guy had used a plasma cutter to cut an AC compressor open, when it was still under pressure. Something like, he ended up in the hospital as a result. How much PSI does a scroll compressor usually hold?
the video is factually correct with good usage of technical terms that most technician would have a problem with. Plus, a good explanation of why the temperature of the vapor refrigerant is increased was made. Some people would mistake increasing pressure means increasing the temperature but in fact the superheated complete vapor does not correspond to pressure/temperature relationship.
6:41 I live in a desert (+120F in summer). Many people suggested to insulate the section line that goes back to the compressor in my car to have colder AC. What do you think about this, will it harm the compressor because I made the refrigerant much colder than I supposed to be?
i still have a troubleshooting card on compressors from way back in school there are so so so many possible reasons for failure of a compressor your have to be a genius to remember them all , !
I thought it be cool to make an off grid refrigeration system based on an open Drive compressor. Then you could have a DC motor spin it and be able to swap it with a gas engine, propane engine. Whatever you want. Control system would be difficult but totally possible. Love the videos by the way learning a lot
Please help me understand my Copeland compressor. It is a scroll compressor from 2000. There’s another cylindrical tower next to it it’s probably 1/4 the size of the compressor but similar in appearance. What is this other piece of hardware do and what is it called? You have a great videos thank you
Excellent Information... Which is best book in the market (In English Language) which guides about all types of Compressors from Individual use to Industry level...
Amateur question here: if the compressor is working and winding resistance is correct, how do you know if compressor is mechanically bad? Will it not be able to reach condensing pressure? If so how will you be able to differentiate between mechanically bad compressor and low refrigerant charge? Would you just have to weigh out refrigerant then refill system and condemn compressor? Please constructive feedback only, no supertech comments. I admitted up front it’s amateur question .
Dear sir very good video!!! In my country Greece all speak about compressors with Hp and this make a lot of misunderstanding!!!Is that way in your country ???What is your opinion about that?
What is outer and why it becomes faulty and make the compressor junk. Also when it burns, its windings damaged no smell comes out. It just list and stop, and become junk. Here I am talking about 1, 1.5 and 2 tons ac units. Yes the coiss are condebsers develop hokes and result in loss of valuable gas. You are not talking about ampheres,which may raise to 9 amphers.
Lost me on the increases temperature and not heat statement when you immediately went to it "losing that heat". Think you meant increases in temperature means it increases in heat density, meaning amount of heat contained within something . But spot on none the less.. just a way of wording things that had me questioning my definitions of things.. :)
I would love to hear your thoughts on l.a.c.'s I am producing a custom 40 ton wall mounted unit and we are having trouble with out l.a.c. especially on startup.
It’s actually an increase in density. The denser you pack a liquid, the more energy you’re gonna get (heat that is built up). The compressor packs the refrigerant into a condenser, but it also pulls on the suction line, creating a vacuum. It creates both hot and cold at the same time.
Is it possible to change the frequency compressor (RSporand) with another cylindrical (rotary) compressor in the same capacity or vice versa without changing the capillary in the same mechanical circuit? Sorry for the translation
