Abstract

In this communication, energy and exergy analysis of building-integrated “earth air tunnel heat exchanger” (EATHE) and “borehole heat exchanger” (BHE) has been studied for a composite climate of Delhi. A mathematical model has been developed to predict the energy and exergy of the system. Computational fluid dynamics software has been used to compare the exergetic performance of both the systems. This work is the extension of Kaushik et al. (J Renew Sustain Energy 6(1), 2014 [1]) and Lal et al. (J Renew Sustain Energy 6(2), 023123, 2014 [2]) where economic analysis has been done for both the systems using year-round performance analysis method. It is found that the borehole heat exchanger is more economical in fixed cost and recurring cost and gives improved year-round performance than earth air tunnel heat exchanger.
