India Achieves Breakthrough in Solar Technology

Posted on July 5, 2011 by

On 1 July, 2011, Union New and Renewable Energy Minister Dr. Farooq Abdullah inaugurated the world’s highest efficiency solar thermal cooling system at the Solar Energy Centre in Gurgaon, Haryana. The 100Kw Solar Air-conditioning system works at a  ground breaking 30 percent higher efficiency compared to current available systems.

The technology is based on the new triple effect absorption cooling technology which includes an indigenously built medium temperature high efficiency parabola troughs (solar panel) for collection of solar energy and effective solar thermal energy storage in the form of phase change materials.

The present system will cater to air-conditioning needs of 13 rooms of solar energy centre. To achieve this, 288 sq mtr of solar collector area has been installed which generates nearly 60 kW of 210A°C pressurized hot water. This heat is used in vapour absorption machine to generate 7A°C chilled water which in turn circulates through the fan coil unit installed in the thirteen rooms.

What is interesting about this technology is that apart from generating solar power, more cooling is possible as the day gets hotter. The system is expected to meet the growing demand for air-conditioning in India in highly efficient and cost effective way through use of direct solar energy.
