Dynamic performance analysis of a combined cooling,heating,and power system based on PEMFC-ASHP integration
摘要
Abstract
The proton exchange membrane fuel cell(PEMFC)is an electrochemical energy conversion device that converts the chemical energy of hydrogen fuel into electrical energy,characterized by advantages such as high energy efficiency,low emissions,and low noise.The air-source heat pump(ASHP)is a device driven by a small amount of electricity to upgrade thermal energy from low-grade to high-grade,capable of providing cooling and heating for buildings according to different seasons and meeting domestic hot water demand.The combined cooling,heating,and power system based on PEMFC-ASHP employed the fuel cell stack and ASHP as dual energy-driven units.Through heat pump technology,the waste heat generated during the power generation process of the fuel cell was further utilized to simultaneously provide electricity,heating,and cooling for building occupants,thereby achieving high-efficiency energy utilization in the combined cooling,heating,and power system.The results showed that the ASHP could enhance the operational performance of the PEMFC system.The system's energy efficiency reached 150％,the coefficient of performance of the ASHP subsystem ranged between 2 and 4,the net power generation efficiency of the PEMFC was approximately 40％,and the overall exergy efficiency of the PEMFC-ASHP integrated system reached 44.46％.关键词
