Hi All,
Been a member of this forum for a long time now, enjoying everyone sharing their knowledge, this is my first post and would appreciate some feedback from around the globe.
I've been working on a milk vat run by 2 maneurop mtz100's that has recently had a heat reclaim hot water system added into it. We were called out due to a slow pull down time and found the compressor to be venting on the internal relief valve. (Set at 30bar) R438a which equates to approx 70c) the hot water system is supposed to be set for 85c with electric booster elements of course)
I guess my questions are
Should there be a check valve installed in the discharge line to prevent higher pressures coming back to the compressor when the electric booster elements kick in?
Could this high pressure coming back onto the head of the compressor caused the failure of the relief valve?
Thanks for your time, hopefully you guys can give me some good feedback.
Cheers
