A novel natural gas based combined heating and power (CHP) and ground source heat pump (GSHP) coupling system has been suggested and analyzed in terms of first law of thermodynamics. In this paper, the performance of the novel system is investigated from the perspective of second law of thermodynamics, and the calculations are completed by the combination of Aspen plus simulation and theoretical derivation...
The efficient utilization of the waste heat with mid-low temperature from the combined heating and power (CHP) system is crucial for the improvement of the energy efficiency. In the CHP system, the waste heat with mid-low temperature was directly used to generate domestic hot water or heat by the heat exchanger. Different from common methods, in this paper a new utilization approach of the waste heat...
A system integrating CHP (combined heating and power) subsystem based on natural gas and GSHP (ground-source heat pump subsystem) in series is proposed. By help of simulation software-Aspen Plus, the energy performance of a typical CHP&GSHP-S (S refers to ‘in series’) system was analyzed. The results show that the system can make a better use of waste heat in flue gas from CHP (combined heating...
