India is blessed with excellent solar radiation with an annual average global solar irradiance of 4 - 7 kWh/m 2/day which can be harnessed through heat and electricity. Hence, it is sensible to shift towards solar energy solutions to meet these demands. The high electricity demand also takes a toll on the national grid and results in the blackout. Fossil fuel based power plants has substantial negative impacts associated with them in terms of public health as well as a contribution to global warming.

At the moment, 73% of India’s energy demand is predominantly met by fossil fuels. Received accepted 28 August 2016 published 31 August 2016Īir conditioners account for 45% of the total energy consumption in the residential and commercial building sector in India. The results of the simulation and parametric analysis are analyzed and presented in the paper. The effects of storage tank volume, collector area and collector slope were also investigated for parametric optimization. Single effect absorption chiller was used because of its commercial availability. Evacuated tube collectors were selected because of its market availability, ease of manufacturing and proven technology. Cooling load estimation and comfort conditions required for the building were determined based on ASHRAE standards.

Hence, the main objective of the work is to model and simulate a solar absorption cooling system for GERMI office building located in Gandhinagar, Gujarat, India, using the transient simulation software ‘TRNSYS’.

Solar thermal air conditioning can be the solution to these demands and can contribute to about 15% to 20% of India’s total oil consumption thereby reducing the dependence on fossil fuels. Consequently, CO 2 emissions from conventional buildings in India were estimated to be 98 metric tonnes of CO 2 per million ft 2 in 2014. Cooling activities (HVAC) in commercial buildings consume 55% of the total energy utilized. Commercial building sector accounts for 8% of the total electricity consumption in India.
