Hall of shame.

Yeah, but I still miss the reason why they required one extra liquid receiver. I see one already. Or isn't it?

There was no reason.He put it there because he thought it was supposed to be there.

That reciever is plenty big enough to hold the charge in that system.

How about this one.Afew years ago I was commissioning on a supermarket refit,as usual the cases were coming on line in stages.As the weeks went by the last of the cases were fitted and then the problems started.The pack was running flat out and the cases were not getting temperature,suc press was almost 70 psi(R404).I got on to the project manager and told him I was having major problems with the plant, and he threw a wobbler "what the !!!! have you done wrong on the commissioning you useless !!!!"was his reply.I said that in my opinion the pack was undersized for the case duty,but he said the pack design duty was 15% above the case duty.The company sent in a "troubleshooter" to check my work.He started cutting risers looking for oil logged pipes and baisicaly pulled the job to bits and would not listen to me.After almost a week he left site and the problem was not rectified.The design engineer went through all his sizeings and said they were spot on.After almost two weeks of empty cases the problem was found.The case manufacturer had upped the sizes of the case evaps and had not told anyone,we had to put 36" on a condensing unit And the plant ran as sweet as a nut.

Hi Ronb

Who ended up paying for the C**k-up

[RONB]

As far as I know the case manufacturer got hit with the costs.I got lots of overtime though.

I work in the Transport Refrigeration side, as it is a small industry there's not many of us at it. The whole industry is short staffed.
Going back a few years we took on a commercial engineer who in his words was 'the dogs b******s.

After a few weeks in the workshop he was moaning about not getting the chance to get on site. A job came in localy and off he went, (just a simple N.P.T)

After half the day had gone with no contact from the 'Engineer' i was asked to call in to where he was on my way back to the depot.

"There's something wrong with the compressor, I know the engine's turning the right way but the compressors running backwards the pressures are the wrong way round"

Bearing in mind the compressor will run either rotation this was baffleing. After climbing up the ladders and having a nosey I told him what the problem was.
"You have your gagues on the wrong way round"

"NO I HAVE NOT, look i followed the pipework back to the compressor, there's the accumilator tank back to the compressor"

Thats the RECIEVER tank I said!!!

Why he followed the pipework back and missed the condensor doing so I do not know

that last story reminds me of a guy who started with the company I was with at the time . Sent him to a commercial refrig job. He came back later and was asked , how did you go .. he said

"There was some bubbles in the sightglass so I let the gas out until there wasnt any bubbles" !

He was marched out of the place .

I guess the LP was at fault as well if it kept running after he worked his magic
