water cooled condenser
hi,
symtoms are
high head pressure @ 23 brg.
discharge temp @ 85c
suction pressure @ 10brg
suction temp high @ 20c
high compressor amps @ 9 ish amps x 3
it is a trane dx water cooled condenser, with a head pressure regulator...checked temps across reg and it is fully open to the condenser bundle, anybody got tips on good confirmation that the hex is insufficent??..overcharged has crossed my mind but discharge temp is higher than normal

Re: water cooled condenser
Sounds like shed loads of non-condensibles to me.

Re: water cooled condenser
Pressure doesn't mean anything without knowing what refrigerant is. If that is R410A then pressures "looks good".
Also without evaporator air in and out temperatures and condenser water in and out temperatures, nothing meaningful can be said about system problem.
What is "hex"?
What means "high compressor amps @ 9 ish amps x 3"?
Please without slang. We are not gang members, we are refrigeration engineers and we need precise language for understanding descriptions of our problems.

Re: water cooled condenser
ok
high load in the room...air on 31c and 26c off with 2 stages of cooling running....
the system operates on r407c
the other stages superheats, subcooling,discharge temp is ok and has a running amps of 7.6 ,7.8 ,7.2...
i am getting a differences of 3 degrees between condenser water in and out on both bundles..
aswell back pressure is 5 brg but superheat is 18c..
subcooling is also low 5c
any more info?Last edited by philjd26; 05-08-2009 at 09:29 PM.

Re: water cooled condenser
temp on condenser inlet was 65 and 45 out...
will reclaim and recharge tomorrow
thanks men

Re: water cooled condenser
no, sorry water entering is 28c and 32c out of condenser..
discharge gas entering 65 and 45 out of condenser...

Re: water cooled condenser
Do you have suction accumulator in your system? With R407C it should be without suction accumulator because of fractionation.

Re: water cooled condenser
thanks for reply gary.
the condenser bundle is part of a bigger system consisting of many other condenser cooled by a main plant. also the condensers are located in a lower area to dry cooler, would this air not make its way to the top???

Re: water cooled condenser
hi
still have no solved this problem ...however i have further information...
this curcuit has a head pressure regulator, could this be faulty and causing abnormal head pressure/temp and suction head/temp....
the unit is a trane CCU model no. EUEB2208A
any sure test to confirm the regulator??
