Air bleeders piped to drains?
Dears
I have leak in chilled water leak in network. Observed consumption of make up water 60 l/hr.
Didn't found leak by visual inspection of pump rooms.
Is there any way to find leak area?

Cracked U bend in a coil? Are the condensate drains plumbed right over a floor drain?

If you have them I would start with checking the automatic air bleeders. You can walk the pipe at the same time. Then go to the coils.

Failed plate heat exchanger that has secondary pressure lower than chilled water loop pressure .

Except that the OP says he confirmed there are no leaks by visually inspecting the pump rooms.
With commercial work, Many times, the problem doesn’t exist in the room with the problem.
I can walk into a building with 100 VAV boxes, and look in the mechanical room, and determine there’s no leak in that room.....doesn’t mean there aren’t any leaks out in the other 10,000 feet of piping.

Have you noticed an increase in water volume in the lower pressure system?

You might need a different language translation tool.
That last response didn’t make any sense.
By what I read you are up to 110 Liters/hour make up (or 30 gallons / hour). Pretty big leak.
Walk the system down and find all air bleeders and manual vent and drain valve that might be dumping water to drainage system. Close them or cap them as best you can. See if that accounts for all or part of your makeup.
If you do not find any external leakage, you better start isolating and doing a pressure drop check on various sections you can isolate to rule out or verify where the leak is or isn't.
Good Luck
