摘要:
为了克服微型分布式供能系统空调负荷的不足和内燃机在低负荷工况下运行时效率低的缺陷,提出一种基于混合动力燃气热泵的独立供能系统.在分析冷热电(模式A)、热电(模式B)以及冷热(模式C)3种不同工作模式运行过程的基础上,分别建立了其动力系统的能量传送数学模型.模拟结果表明:动力系统在燃气机输出负荷率为70%~80%之间时,热效率较高; 在3种不同的工作模式中,模式C的动力系统的热效率最高,最大值到达0.4以上,模式A的动力系统热效率次之,模式B的动力系统热效率最低; 本系统在热泵空调模式(模式C)下运行时,比常规的单一燃气发动机驱动的热泵空调系统节能,动力系统的热效率总体提高约3.5%.
Abstract:
In order to overcome the shortage of air conditioning load and the irrational thermal efficiency of internal-combustion engine in a mini-distributed energy-supplying system, an isolated energy-supplying system of gas engine-driven heat pump is presented, and the principles and characteristics of the system are also delivered. After analyzing the operating mode A(heating power and cooling), the operating mode B(heating and power), and the operating mode C(heating and cooling), the mathematical models of energy transmission about the three operation modes have ben established, respectively. The simulation results show that when the part-load rate of the gas engine is between 70% to 80%, the thermal efficiency of the power system is higher, and the maximum can be more than 0.4. Furthermore, among the three different operating modes, the thermal efficiency of the power system is the highest in operating mode C, less in operating mode A, and the least in operating mode B. Notably, in the operating mode C, compared with the conventional gas engine-driven heat pump system, the average increase of the thermal efficiency of power system can be about 3.5%.
