Emirates Central Cooling Systems Corporation (Empower) has implemented its ETS Flow Optimisation using Statistical Process control for all the buildings it served in Palm Jumeirah Crescent area in 2014
The system has achieved significant results in energy conservation. The system has achieved an improvement of 0.045 kW/TR which has resulted in more than 4 million kWH of Electrical Energy saving and more than Dh2mn in one year.
Empower succeeded in developing the ETS Flow Optimization using Statistical Process Control, which is widely used in the manufacturing industry to improve the quality. This comes in line with Empower's commitment to meet users’ requirements in terms of quality of service.
Each building served with district cooling is equipped with ETS (Energy Transfer Station), heat exchangers, temperature control valves, sensors and a control system.
The control system is programmed in such a way that the temperature control valves maintain the required water temperature without affecting the building’s cooling requirements.
The Temperature Control valve regulates the flow so as to meet the customers’ chilled water demands while maintaining the optimum temperature of the return water to the district cooling plant. Standard deviation is used as a measure for the performance of the valve.
The parameters governing the valve control are fine-tuned to achieve a desired Standard deviation which in turn improves the overall performance of the district cooling Plant.
“District cooling is still growing in similar energy sectors in the Middle East. We need to have better systems to measure compliance with quality standards to achieve the best results,” said Ahmad Bin Shafar, CEO of Empower.
“We strive to reach the highest levels of customer satisfaction, by taking better measures to help us meet our commitments in terms of operational and service standards, through the ETS Flow Optimization using Statistical Process.”
“This supports the implementation of our strategy, in line with Dubai’s Integrated Energy Strategy, which aims to secure sustainable energy supply, enhance demand efficiency, and contribute to environmental protection through energy and resource conservation, for generations to come.”
