Forward-lookingWaterTemperatureControl

TICA OFC centrifugal chillr can adjust its capacity output in advance based on thewater temperature,quicklymatch the required load,and effectivelyreduce the water temperature fluctuation.

The forward-looking stable control solution enables the unit to adapt to various operating conditions,to implement self-diagnose and adjustment by predicting the trend,and to avoid frequent changes in temperature and even shutdown,so that theunitcanmaintain eficient,stableand safeoperation inreal time.

Themicrocomputercontrol systempredictsreal-time load changesbasedon targetvaluesandload levels,andperforms forward-lookingcorrections tounit loads,thusavoiding energy consumption increase or evenshutdownof the unit dueto frequent fluctuations inwater temperature of theunit.

Inaddition,the powerful control logiccannotonly protect thereliableoperation of the unit,but also expand the operation range of the unit,enabling the unit to adapt to variousoperatingstates.
