A new solar combined cycle integrated with heat pump system

摘要

This paper develops and studies a solar combined cycle system that is integrated with a solar-assisted heat pump for providing electrical power, space-heating, space-cooling, hydrogen, and hot water. Thermodynamic analysis through exergy as well as energy approaches is employed for assessment and evaluation of the overall performance of the system. The proposed system is also assessed by performing parametric studies for observing the impact of several factors on the overall performance of the system. The results of this study show that the energy efficiency of the multigeneration system is 52% while the exergy efficiency is evaluated to be 42%. Moreover, hydrogen is produced at a rate of 0.51 kg/h while the power outputs from the gas turbine and steam turbines are 50 MW and 3.25 MW respectively.
