We are talking about a freezer 2*2*3 metres. technoblock CSK 300U with comp. TFH 2511Z. one year ago one of my coworkers changed the capillary tube into an automatic valve( the one that is to adjust, without bulb)
Now the freezer could hardly go (the whole year round) below -16C. I was there yesterday to fix this problem but couldn't make it. had a terrible dispute with my boss. Tried to adjust the valve till suction was at 1,4 bar. (although 1,1 would be better) It was running 2,0 bar when I arrived and chamber was -16C. I tried to fill the system till compressor got cold but it got off on clixon. after 45 min I tried again (after changing drier)to adjust to 1,5 bar but again it got off on clixon. I tried several hours and nothing would be better than 2,0 bar suction. Then comp. got cold enough to keep running. I now think that this valve is not suited with this compressor for this purpose: -22C. My boss thinks it CAN replace the capillary tube.
what are you thinking of it. After the dispute with my boss I decided to quit. He called me incapable and irresponsible of my job. I even worked from 8am to 11pm and that was not enough to be responsible of the job?
