Re: Ammonia refrigerator control by inverter
Hello, Tycho & Josip,
Thank you very much for your advise.
I just come back from Chinese New Year Holiday.
About your advise for start/stop peroids,
I still do not understand clearly.
May I confirm my understanding.
- Close all solenoid valves when we start compressor
- Run compressor at min speed until oil pressure up to normal operation level.
-open solenoid valve one by one until all open.
- motor speed control by temp control loop.
Is it correct?
By the way, I still do not understand clearly about the reason why.
I guess because of energy saving purpose. is it correct?
