Cooling Tower Problems

hk cooling tower auditor, cooling tower problems
by John A. Herbert


Air-conditioning and process systems use cooling towers to reject heat from the chiller or process machines. These water based cooling tower systems provide owners with significant benefits over air-cooled systems, including lower energy costs, smaller size, and lower sound levels.

It is still important that towers are checked to ensure reliable performance and efficient operation.

In 2000, 32% of the total electricity consumption in Hong Kong was used to drive air-conditioning. Furthermore, Hong Kong buildings consume approx. 85% of all electricity generated in Hong Kong contributing significantly to local emissions. Converting to water based technology, namely cooling towers offers superior energy advantages, reduces power station pollution and helps keep more of your hard earned money in your pocket.

Troubleshooting Cooling Towers

Many cooling tower systems do not operating as intended, consuming more energy than the promised savings indicated, Kelcroft, with our unique blend of expertise, identifies and resolves cooling tower problems.

Many cooling towers are open, direct type cooling towers, and run into performance difficulties because in addition to their primary duty, to cool condenser water, they are efficient air cleaners.

If you have an open direct type cooling tower, that dirt will collect in the condenser water system, forming mud and sludge, and eventually plugging the fill, and the heat exchanger.

Cooling Tower Water Treatment

Water treatment is essential to maintain the condenser water quality is often poorly designed, or badly operated, we always find problems with the chemical water treatment systems.

Often the water treatment is delivered into bypass or side stream loop. However, this piping loop arrangement is poor, and air locking results.

Cooling Tower Controls

We know from experience that cooling towers are not always installed in correctly, and not properly integrated into the control strategy to operate at peak efficiency.

The tower itself is only one part of the air-conditioning system, the goal to create a reliable energy efficient system including all the components, chillers, pumps, and cooling towers.

Air Flow

If the cooling tower is not properly positioned, the tower exhaust flow may short circuit to the intake, causing serious operational issues.

Legionella

Of course we cannot overlook the connection between cooling towers and Legionella. Cooling towers are a known source of Legionella bacteria, the cause of Legionnaires disease, and measures must be enforced to mitigate the health and safety risk.

There is clear and documented risk of the potentially Legionella infection assocated with cooing towers, the largest legionella outbreaks being linked to cooling towers. Click here to read more about Legionella in the Hong Kong built environment

In Hong Kong cooling towers owners are required to engage independant expert auditor to undertake annual cooling tower audit report, and submit to HKSAR Government.
