Frozen Busted McQuay Chiller Tubes.....

[jon98tt]

Okay, everyone hold on!

If anyone on here actually read each post fully and comprehended what they read then you would have realized that i am the OP. I started this thread. I understand what caused my machine to freeze. I never questioned why it froze only what to do about it now, i personally have never been in this situation so i had a few questions. I wasn't holding the recovery tech's hand while he recovered, i had other things to do.

If you looked at Post #28 and #34, i was simply asking "browntrout" what caused his machine to freeze. If you look, he posted that one of his mechanics just froze subcooler tubes....... I was simply wondering if he had water flow through the machine when it froze and if so, did the machine totally flood....

If everyone would just stop being keyboard warriors maybe this site would actually help ppl.

KnewYork- Thanks for your responses, they have been helpful!:

I take exception to this kind of answer. Are we here to help others who might not have the experience that we may possess or are we here to somehow dismiss questions by making wisecracks? If it's the latter, it isn't working for me. If one doesn't want to take the time to answer a question...fine...don't.

I answered the way I did as it is obvious to me and others that Jon never bothered to take the time to read all of the posts as to the situation .
Any fool with a PT chart can tell you why it froze it aint rocket science ....look under how to read a PT chart 101 the answers are all there .

If I remember correctly one of the questions on the Canadian CofQ exam to get your licence in refrigeration goes something like this .

When removing refrigerant from a high pressure water cooled chiller what MUST you ensure ?? ....
choose from the following answers
A- water flow .
B- wear your rubber boots .
C- phone a freind and tell him what your doing .
D- make sure you have lots of coffee its going to be a long job .
JMHO
P.s Yes I do have a strange sense of humour that doesnt appeal to everyone

Its funny that you accuse me of not reading previous posts when in fact it was YOU that didn't read all the posts.... Read it again and maybe you'll understand what i was asking.

Jon,

After I responded I realized you were the OP. This particular situation hits home with me because I spent a great deal of time training a Journeyman (with questionable credentials) exactly how to transfer refrigerant. After I left the company, I learned that he froze some tubes in a chiller while transferring refrigerant. He tried to pass the blame to another journeyman by saying "That's what he told me to do." He had no excuse because he broke the cardinal rule of continuing to remove vapor below the freezing point.

Yes i understand completely, I have personally recovered and overhauled many machines and i understand proper recovery techniques. The only reason i decided to sub out the recovery process was because our large high pressure recovery machine was being used on another job at the time. I am the service supervisor for my company so even though i wasn't the lead mechanic on the job, you can see why this whole situation would fall into my lap.

Jon , my apologies . I did misread the post , you are the original poster .But when you see posts about how did you freeze the tube and did the machine flood . Those questions are so basic when related to refrigeration and chillers .
