Working process of heat exchanger

The glycol cooling system, heat exchanger, fermenter, bright beer tanks are a whole. In Tiantai beer system, we always match with 2 set of chiller in the glycol cooing system. And what is the function of heat exchanger? What is the working process? Is heat exchanger still necessary if there are 2 chillers?
Whether you choose cold water or cold water combined glycol water, the chillers are used to cool glycol water in glycol water tank only, heat exchanger can cool wort because cold water and wort will exchange heating with each other.

If two-stage heat exchanger, the process will be:
Glycol water from the glycol water tank cools two parts:
The first part is to cool the wort via heat exchanger
(This takes place in the second stage of the heat exchanger, the first stage is usually cooled with city water),
The other part is to cool the fermenter and bright beer tank.

If single stage heat exchanger, the process will be:
Glycol water from the glycol water tank cools one part: fermenter and bright beer tank.
Then the wort will be cooled directly by the cold water through the single stage heat exchanger.

So chillers cannot instead of heat exchanger, they do totally different works in the whole cooling process.
Now there are 2 kinds of heat exchanger. Two-stage and single stage. Two-stage is very common but consider of energy saving and sanitary, the single-stage is more and more popular now.
For two-stage heat exchanger, the first stage is cold water, the second stage is glycol water.
For single-stage heat exchanger, it just cold water. So it will be more sanitary and safe for wort. Also heat utilization rate obviously increased, and it is easy to control and operate.
