Brahma Kumaris World Spiritual University is a spiritual organization spread across India and many countries around the world. The institution has set up an educational and training campus named Om Shanti Retreat Centre (ORC) in Gurgaon, Haryana.
About the Project
The campus had a solar and diesel hybrid (conventional diesel fired boiler) system for cooking. The system comprises 28 parabolic concentrators installed in two separate modules of 7 pairs each and is reflecting sunlight on a total of 14 receivers. The system is designed to cater for 600 meals per day. The organization has dedicated trained personnel for the maintenance of solar cooking system, who takes care of the cleaning of dish, painting of the receiver and repairing of the insulation of the piping etc. The Scheffler dishes are being cleaned twice in a month and receiver is painted black once in a month to increase the absorptivity of the receiver. Damaged glasses of dishes are required to be replaced as and when required.
|Capacity||28 Scheffler dishes with an aggregate collector area of 266 m2|
