Hello from Uzbekistan. We having problem with our chiller system. After the winter time we can not to start it. All system with water. I need your advise. Thanks in advance
Common problem. Off cycle allows liquid to accumulate in the discharge housing. Then it starts and explodes. Seen this a bunch in high ambient and low ambient temperatures. The other thing that will happen is it blows the 90 degree fitting apart. Hydraulic force is enormous!
Our RTAC 155 comp 2 used to sound normal. A repair to the evap bundle was needed, after repairs has a rhythmic ticking sound. I have two vids demonstrating the noise. Would you be willing to listen to it.?
How much will be aproch temperature condenser and evaporator temperature? What is the difference between aproch temperature , superheat and condenser subcool.
Approach Temperature will be 1 To 2 degree centigrade. Approach Temperature is leaving water Temperature minus saturation temperature(condenser or Evaporator) Suction superheat is suction temperature minus suction saturation temperature. Discharge super heat is discharge Temperature minus discharge saturation temperature. Subcooling is liquid line Temperature minus liquid line saturation temperature. For more information stay tuned I will upload later.
Friend I hope you are well I had a similar failure but the chiller turns on and alarms due to high oil temperature, I preceded removing the discharge service valve because it generates a loud noise. My question is it causes an obstruction in the system ..? why is it triggered by high oil temperature?
Please check the all condenser fan motors, and Run the circuit full load and check the oil Temperature. If compressor not going full load, check the solenoid valves on compressor, check the oil cooling system. ( few days ago I rectified same problem high oil Temperature. I found solenoid valve coil was defective)
Very good replaced discharge service valve. Excellent job.Lots thanks
Nannaitunde cheta 👍👍👍👍👍👍
Very knowledgeable video
Marvelous vedio my friend
Very good chiller.
Good job bro✅
Hello are you leaving in kuwait
Thnxs more Nd more
Can you Freecool on a train chiller

would a check valve solve this issue?
No. It’s from migration. A heater on the line will help.
Very good

Whats the nitrogen pressure u charged. Did u recovered the gas .
Yes I recover the refrigerant. And I charged nitrogen pressure 100 psi whole system
@@HVACTechGuidebysreejith can I have your contact please ..
Good job
That was a good find:) nice job
Did you charge liquid gas on the suction line? Is that okay for a screw compressor?
good video thanks
Why train rtac 200 make noise while on and off, what would be the reasons
Sir how to know screw compressor if pumping fail. In running chiller please reply me

How can change control circuit

@@HVACTechGuidebysreejithSir, Can you please explain this troubleshooting through video.
Chiller train rtac 350 the problem was Compressor command coming A1 and Compressor started B2 why like this
8:15
Never worked on a screw, my heart dropped at every different sound,
:29 naw its just in self cleaning mode
kyu jyada sou ata he oto bataie
can not hear you
He’s not talking.
Wrong information
Nice job
Good job
