DE-13-C067 -- Comfort Cooling for a 200,000 Square ft Yoga Hall PDF

Lying at the feet of Lord Shiva's hills, i.e., Shivaliks, in Uttarakhand (India) is the ancient city of Hardwar. Legendhas it that the Suryavanshi prince Bhagirath performed penance here to salvage the souls of his ancestors whohad perished due to the curse of sage Kapila. The penance was answered and the river Ganga trickled forth fromLord Shiva's locks and its bountiful water revived the sixty thousand sons of king Sagara. In the tradition ofBhagirath, devout Hindus stand in the sacred waters here, praying for the salvation of their departed elders.

'Baba Ramdev's' ashram in Hardwar called Patanjali Yogpith is the spiritual destination of large numbers of Indian andforeign devotees. The Yog Hall, where thousands of people practice YOGA in the presence of celebrated YOGA GURU --BABA RAMDEV, is a mammoth hall with an area of 200,000 square feet, large enough to accommodate 30,000 people. Itis 115 m / 377 ft wide, 165 m / 541 ft long and 13 m / 42.6 ft high. While air conditioning the hall would perhaps give tothe yoga practitioners physical comfort commensurate with the spiritual bliss they experience there, it would be rather anexpensive proposition. But the salubrious climate of the holy city offered an affordable solution. Rather hot and dry in thesummer, but moderate in the winter, the climate is ideally suited for evaporative cooling. Therefore, the Patanjali YogpithTrust that runs the ashram, decided to install an evaporative cooling system in Yoga Hall. We received the order to executethis project.
