Working on chiller, for cooling paper rolls, need advice

[bharatbaldwa]

Hi all,

I am a 3rd year chemical engineering student and on my internship, I am asked to undergo an energy saving project, which requires me to work on a chiller, its primary and secondary heating circuits, and the distribution pipeline, which is used for cooling coating and calendering rolls. As I am very inexperienced, can someone who works on this kind of systems pls suggest me how/which fields I can start looking into to have energy savings.

Its an air based chiller, with four compressors, pumps are adjustable.

I would like a broad idea as to what all factors contribute in the working.


Thanks
Bharat

i think, some more detail wil be helpful, the compressed air is used to cool primary water, which in turn flows through a plate heat exchanger to cool secodary water circuit, which runs in the process, direct use of primarily cooled water was giving contamination problems due to coating materials.

also can any other liquid which has better heat transferring capacity, and doesn't have pumping problems can be utilized in either primary or secondary circuits instead of water. :O

Here's a little light reading on the basics
