i dont mean to be off topic but does anybody know of a method to get back into an Instagram account..? I stupidly forgot the login password. I appreciate any assistance you can offer me!
Two things helped me more in my career more than anything else. 1) Copeland's Compressor Operation and Service Seminar and 2) Sporlan's seminar on all of their refrigeration components. I recommend both to anyone who wants to be a serious technician who understands how HVAC/R systems work.
This is amazing! Absolutely love this video. We have a twin head here which 4 out of the 6 pistons were cracked in half and the whole inside was mangled. on a rebuilt unit This really gave me a better understanding. I appreciate it!
Thank you guys for sharing all this videos! They´re really useful for refrigeration beginners like me, greetings from Mexicali Baja California, Mexico!
I have been seeing a lot of broken conn rods in 05G compressors in reefer trailers, I think next time I will check super heat. and pay closer attention to refrigerant oil level. Thank you so much for posting this stuff from Emerson!
I remember these classes in certifications through Copeland they were fun nothing's better than find it in the real world though have a bunch of semi-hermetics I remember I used to have to work on daily I find the valve plays with the back of reeds shattered into pieces some of even stabbed the piston head and I did at one point for an emergency repair have to take off the thermal senses the s1 S2 S3 and redo the wires inside of the compressor Man that was fun when you're young but when you get older you don't want to do that anymore especially when most companies won't pay you for that kind of stuff
This is awesome cause I have a dental compressor with two Copeland heads and one has some sort of short. I’m probably not gonna take it apart but it’s great to know what is inside.
the one from 98 looks like one of the compressors on the new a/c installed in my middle school gym during 98. that huge thing always fascinated me. wonder if it's the same compressor?
This was great right now I have a 4dr3-3000-tsk-236 that trips on oil It's in a seasons 4 hot/cold deck unit The system is a mess. I work in NYC you would be amazed what some guys do here. I was going to start by pulling the heads changing the oil and cleaning the oil pick up screen. Any other suggestions
I am suspecting that when you charge a copeland scroll with liquid through high side while under vacuum causes internal damage with the result being equalized pressure while running....If so why?
15:55 - chart listing cause of no superheat? PT Chart? He must not be talking about a pressure temperature chart when he says PT Chart. What PT chart is he referencing?
There are some PT charts that contain more information than just the pressure temperature relationship of a specific refrigerant. Some charts also contain troubleshooting tips.
Adam HVACR Length x Width x Height and then you calculate the crankshaft to the top of the block including the deck height...61.02 cubic inches equal 1 liter so if you have 3 cylinder compressor with 1 liter per cylinder that means you take 61.02 x 3 = 183.06 cubic inch is the volume of refrigerant. Compression ratio if Rod length is 5 inches and the bore is 3.3 inches and the stroke is 11” then the compression ratio is 23.4 to 1. Which is good now you need to figure out ambient temps and that’s will get you a good start to figure out what you need but you may need to Oversize a evaporator to absorb more heat
This is an hvac school ? How is the student going to learn, unless he / she actually takes the unit apart. Watching the teacher, when its supposed to be hands on by the pupils. This must be one of those free seminars where they feed you pizza and Pepsi for lunch.
