Energy savings analysis of fuel-cell microgeneration systems with ground source heat pumps in load-sharing buildings

摘要

This paper presents the potential energy savings of implementing a combination of fuel-cell microgeneration (FCMG) systems and ground source heat pump (GSHP) systems in load-sharing buildings. The energy modeling and simulation technology is used to evaluate the effectiveness of FCMG systems in buildings. There are a number of simulation programs to evaluate the performance of buildings with various electric, mechanical and thermal systems. However, it is still a challenge to model and simulate the FCMG systems using the existing whole-building simulation programs. This paper first overviews the current technology of simulation modeling of FCMG, and then presents the results of energy savings analyses obtained from the FCMG systems.
