Late night walk in freezer call

Why is this in my recommend feed? 17 minutes later Never doubt the algorithm.Never doubt the algorithm.

I've just got here from a Technology Connections video about swamp coolers. E: This comment sure blew up.

I work in software engineering and people think I'm a wizard. I'm watching this video and think you're a wizard. Always great to see industry pros doing their thing. Cheers from one industry to another!

I don't know why youtube thought I wanted to watch this, I'm so glad I did though

I recall hooking up a 1/2hp compressor one time with my apprentice . I ran out to the van for something , came back and he had the suction rotolock all done (I was pleased) we vacuumed down , held the “wc drop beautifully, charged , fired it up and suction pressure didn’t move , but compressor sounded like it was in a vacuum , I scratched my head for a min , finally asked , did you pull the rubber plug before hooking up the rotolock ? He said “there’s a plug? “ I had a good laugh ,reclaimed , pulled the roto and there was the factory seal plug 😆 lesson learned ! No idea how this unit had ANY flow , how was this not picked up on day one of commission😳

A little preventative maintenance would have saved them some money.

Learn a trade, you'll never go hungry.

I work in a chemical plant and have done since brand new commissioning. About 5 years later a centrifugal pump stops pumping and ended up finding a 3 inch plastic pipe cap stuck in the suction. It is a clean steam condensate system and that damn cap must have floating around in that tank since new, whoever boxed it up without looking needs a kicking.

I have NO understanding of anything you said, but this was still cool to watch, thanks!

Whatever you're doing you've figured out the you tube algorithm . In my recommended now I'm binge watching

Talk about an expensive service call. Lol that bill was enormous.

Technology Connections sent me!

one trick you could have tried to unlock that compressor is the reverse the phases to make it turn the other way ! maybe could have been lucky . but after that red cap shit you did the right thing

For those boxes with the swamp cooler, since it is so crucial to keep those boxes cool to a certain extent, shouldn't there be like a thermometer type sensor in the box and have it display temp near a cooler, or maybe a little indicator light for if it hit a certain temp, the restaurant personnel can contact you before the same problem of overheating killing off the compressors and fan motors.

When you place you palm flat on a compressor or grab a copper pipe and it is electrified your muscles in your hand contract, involuntarily, you grab on to that item and your not able to let go, you can easily get electrocuted. If using your back hand, your fingers lock up toward you and not on a compressor per say. I know some can describe it better then me. Have great respect for electricity, it can kill you.

On a 3 phase compressor that is mechanically stuck, I usually try to reverse the rotation (on a recip). Just to see if it will un stick.

Technology connection brought me here

I hit 120 F on top of a walk in freezer today, indoors! Customer doesn't want to add fans or a cut in to the outside to bring the temp down. Just counting the days until the compressor dies. That red cap is so strange but it's moments like that you will remember always. Good repair dude.

Finding that plastic cap internal of the roto lok was hilarious. The company I worked for in Windsor Ontario had installed a new 200 ton chiller on top of a 26 floor condo building. The compressor kept kicking out on high head. The guys assigned to it never found anything out of the ordinary. One night I was on call and ended up there. Compressor off on hi head. I climbed onto the top of the water cooling tower and just happened to notice that about 20% of the branch lines at the end of the main 8" water feed line weren't spraying hardly any water. I shut everything down. Was able to pull a couple of branch line pipes off, reached in and felt around. The { it rhymes with plucking } plumbers that connected the water tower had pushed the plastic pipe shipping cap straight into the main supply line water feeder pipe and it got pushed down to near end of the line. Some times it would be sideways and allow sufficient flow, and sometimes it would turn and block the last 20% of branch lines. Pulled it out. That solved that. And the view from up that high on a nice summer evening was outstanding. Keep up the good work. And stay curious. LOL.

Great troubleshooting! That red plastic cap inside the suction line service valve was, in affect, serving as a restriction, preventing enough cool suction gas from flowimg over the motor windings in that hermetic compressor. It's a wonder that compressor lasted as long as it did, given that it never had a sufficient amount of motor cooling, even when it was working. Good work!
