Cooling tower adjusting method and system

1. An adjusting method to adjust a liquid discharge operation from a collection tank of a cooling tower, comprising the steps of:

checking an activation signal of a discharge solenoid valve of the tank;

detecting a flow rate value of a liquid flowing between an inlet mouth and a discharge mouth of the collection tank to allow a discharge operation of the liquid contained in the tank,

wherein said discharge operation is allowed in correspondence of a detection of said flow rate value at least equal to a reference threshold value and wherein said discharge operation is inhibited in correspondence of a detection of said flow rate value that is null or lower than said reference threshold value.

2. The adjusting method according to claim 1 , wherein said detecting step comprises detection of said flow rate value in correspondence of said inlet mouth of the collection tank.

3. The adjusting method according to claim 1 , wherein said discharge operation is inhibited for a time duration equal to a restoration time of said flow rate value, plus an additional inhibition time associated to one or more detecting sensor devices configured to detect said flow rate value.

4. The adjusting method according to claim 3 , wherein said discharge operation is inhibited for a time duration equal to the longest one out of two or more additional inhibition time values associated to two or more sensor devices detecting said flow rate value.

5. The adjusting method according to claim 3 , wherein said inhibition step has a time duration equal to the shortest one of said additional inhibition time values characteristic of sensors devices detecting said flow rate value.

6. The adjusting method according to claim 3 , wherein said restoration time is equal to the duration of an error condition of at least one of said sensor devices.

7. The adjusting method according to claim 3 , wherein in correspondence of a value of said additional inhibition time equal to zero, said discharge operation is reactivated.

8. The adjusting method according to claim 1 , wherein said detecting step comprises processing at least one boolean signal.

9. The adjusting method according to claim 1 , wherein said discharge operation can be mechanically inhibited.

10. An adjusting system comprising:

sensor devices configured to detect a flow rate value of a liquid in a hydraulic circuit of a cooling tower;

a solenoid valve positioned or positionable downstream of a collection tank to allow a discharge operation of the liquid;

checking an activation signal of the discharge solenoid valve of the tank;

detecting said flow rate value of the liquid flowing between an inlet mouth and a discharge mouth of the collection tank to allow a discharge operation of the liquid contained in the tank,

wherein said discharge operation is allowed in correspondence of a detection of said flow rate value at least equal to a reference threshold value and wherein said discharge operation is inhibited in correspondence of a detection of said flow rate value that is null or lower than said reference threshold value,

wherein said solenoid valve is controlled through a signal transmitted by said processing unit so as to inhibit the discharge operation, for a defined period of time, in correspondence of an error condition of said sensor devices.

11. The adjusting system according to claim 10 , wherein said discharge operation is inhibited for a time duration equal to a restoration time of said flow rate value, plus an additional inhibition time associated to one or more detecting sensor devices configured to detect said flow rate value.

12. The adjusting system according to claim 11 , wherein said discharge operation is inhibited for a time duration equal to the longest one out of two or more additional inhibition time values associated to two or more sensor devices detecting said flow rate value.

13. The adjusting system according to claim 11 , wherein said inhibition step has a time duration equal to the shortest one of said additional inhibition time values characteristic of sensors devices detecting said flow rate value.

checking an activation signal of a discharge solenoid valve of the tank;

detecting a flow value of a liquid flowing between an inlet mouth and a discharge mouth of the collection tank to allow a discharge operation of the liquid contained in the tank,

wherein said discharge operation is allowed in correspondence of a detection of said flow rate value at least equal to a reference threshold value and wherein said discharge operation is inhibited in correspondence of a detection of said flow rate value that is null or lower than said reference threshold value.
