Heating, Ventilation and Air Conditioning (HVAC) consume an average of about 50 per cent of the energy in buildings. By installing ABB's Cooling Tower Direct Drive solution in its hotel, JW Marriott Pune has set new benchmarks in energy efficiency, saving about 35 per cent energy annually. Energy saved in a day with ABB's direct-drive solution can charge an electric car to run for approximately 1,500 km.  

A cooling tower is a key component of many refrigeration systems and can be used to provide comfort cooling for large commercial buildings like airports, schools, hospitals, and hotels. Energy is consumed in driving the fan, or fans, necessary to achieve proper air movement through a cooling tower. ABB's direct-drive solution offers the benefits of variable speed control and eliminates the cost and maintenance required for traditional gearboxes or belted solutions.

The fan couples directly to the motor and is controlled by a unique AC drive to provide optimal speed and cooling tower performance that runs quieter with reduced energy consumption. The solution also provides a Quick Start Assistant, making start-up simple and straightforward. 

"When we aim to reduce energy consumption, every possible way to conserve energy must be evaluated, and the most energy-efficient technologies and practices must be implemented.  Buildings offer huge scope in energy optimization and have a great potential in shaping our sustainable future. Investing in energy-efficient technologies can bring both economic and environmental benefits," said Sanjeev Arora, President, Motion business, ABB India. 

World over, buildings consume over 30 per cent of the global energy consumption. For half a century, ABB has been leading the way in optimizing HVAC systems in buildings, using drive control technologies. The group actively contributes to a more sustainable world, leading by example in its own operations and partnering with customers and suppliers to enable a low-carbon society, preserve resources, and promote social progress.
