摘要
In this paper, thermodynamic properties, such as yap or-liquid-equilibrium.vapor pressure, enthalpy and entropy of R22-DMA (Dimethyl acetamide), and the computation method are presented. With the thermodynamic-property database, a basic type of absorption compression heat pump (BSCHR) with recuperator and regenerator was simulated numerically and the performance of this heat pump under the typical air-cooling conditions was optimized. the results demonstrate that a batter coefficient of performance (COPg) can be achieved by optimizing the solution concentration and circulation rate.
