摘要
根据一套10kw级微型分布式冷热电联产系统(采用燃气内燃机发电,地板辐射采暖,吸附制冷机提供空调制冷)在冬夏两季实验研究获得的数据,从热力学第一及第二定律角度,进行热力学分析,与传统的冷、热、电分产系统进行比较,并对不同评价标准得出的结果展开了进一步的探讨。分析揭示了冷热电联产系统高效节能的原因,得出的相关结论为实验系统的改进以及未来实际应用系统的设计,提供了理论依据.
A micro combined cooling,heating and power(CCHP)system is set up on the campus of Shanghai Jiaotong University,comprised of a gas engine,a generator,an adsorption chiller and a heat radiation floor.The data,acquired in experiments of summer and winter working conditions, are discussed by both first-law energy analysis and second-law exergy analysis.Further comparison of contemporary conventional separate of heating,cooling and power for local users shows the potential of energy saving by this novel CCHP system.Finally,the comparison results in optimization of the system and future critical improvement of certain parts in the CCHP system is pointed out.
