摘要
提出描述缸内工质复杂工作过程的零维物理模型和数学模型 ,用R K法求得燃气机的性能参数。利用导出的燃气发动机驱动热泵装置一次能源利用系数PER的计算公式 ,分析并指出了供热系数、废热利用率和有效效率对PER的影响以及增大PER的有效途径。
Provides a zero dimensional model and relevant equations for working medium in the cylinder of a gas engine and obtains the performance parameters by means of the P-K method. Derives a formula for calculating the primary energy ratio and the impacts of heating coefficient, waste heat recovery rate and useful thermal efficiency on the primary energy ratio, and effective ways to increase of the ratio.
