Saudi-based Al Salem Johnson Controls (York), a leading provider of integrated solutions in HVAC equipment, fire and security and building management systems, said it has been able to reduce energy consumption of its clients by 50 per cent through chiller replacement.
Over the last 10 years, it had succeeded in replacing more than 600 chillers for over 200 different projects across the kingdom, in different applications and sectors such as educational facilities, factories, residential buildings and towers, hospitals, offices and others.
So far, the total cooling capacity of the replaced chillers is 145,000 TR.
Among the prominent chiller replacement projects implemented by Al Salem Johnson Controls (York) is the Makkah Construction and Development Company’s Hotel Towers, which consists of 10 hotel and residential towers, with a maximum height of 100 m and 37 floors, facing the mosque on the southwestern side, said the statement from the company.
It is the largest chiller replacement project in the company's history to date, it added.
"When chillers’ age surpasses the 10-year mark, organisations should consider replacing them with new chillers, featuring latest technologies and advanced specifications, which will lead to improve operational and energy efficiency, and to reduce maintenance costs," explained Dr. Mohanad AlShaikh, the CEO of Al Salem Johnson Controls (York) in Saudi Arabia, Lebanon, Egypt and Yemen.
The average lifespan of a chiller is between 20 to 25 years, depending on type and operational load, he noted.
"When the chiller’s operation in a facility exceed 10-12 years, the power consumption and maintenance cost increase drastically; while the operational efficiency decreases," he added.
Twenty-five years ago, 44 York chillers were installed on the roofs of the towers, with a total cooling capacity of 10,700 TR, in addition to York air handling units inside the buildings.
For 11 years, the company has been providing the towers with operation and maintenance services for the cooling system.
"Over the past 10 years, our company succeeded in replacing more than 600 chillers for over 200 different projects around the kingdom, in different applications and sectors such as educational facilities, factories, residential buildings and towers, hospitals, offices and others," stated AlShaikh.
"So far, the total cooling capacity of the replaced chillers is 145,000 TR," he observed.
In 2018, the first phase of chiller replacement began, and the last phase was completed recently, he added.
Engineer Mohammed Rajab Samkari, the Advisor to Chairman of the Board of Makkah Construction and Development Company, said: "We consider Al Salem Johnson Controls one of the strong leading national companies, and its great experience encouraged us to partner with it to replace our chillers."
"The partial replacement of the chillers during the year 2018 has resulted in actual savings in operational expenses and electricity consumption equivalent to about 50%, which was a strong incentive to completely replace the old cooling system," he noted.
Al Salem Johnson Controls (York) conducted a holistic audit of the old cooling system, and accordingly designed and provided the optimal solutions, through replacing the old York chillers with new York YVAA chillers, equipped with the latest technologies and highest efficiency specifications.-TradeArabia News Service
