摘要
建立了空气源热泵的稳态仿真模型,得出了R22和其替代工质R32/R134a系统循 环性能随工况的变化曲线。相同工况下两种工质性能比较结果表明,采用混合工质的系统制 热性能系数高,制热量低,耗功量小,混合工质替代纯工质有一定的节能优势。
Establishes a steady-state simulation model. Obtains the performance curves with the change of working conditions for the systems using R22 and R32/R134a as refrigerants respectively by simulation. Compared with the system of R22 at the same working condition, the R32/R134a system has higher heating COP and lower heating capacity and power consumption,which indicates that R32/R134a replacing R22 has advantage in energy efficiency.
