Problem with an AHU (Need help)

I have an AHU connected to a central cooling plant.

The design is based on supplied chilled water temperature of 5.5 oC (41.9 oF) and return temperature of 14.5 oC (58.1oF).

Actually on site the supply temperature is 5.5 oC (41.9 oF) but the return temperature is 10.5oC (50.9 oF).

And the space is not achieving the required temperature.

What would be the problem:-
- Problem with coil??
- Problem with control system?

Any suggestions????

It may be due to untidy coils, consider cleaning them.
