摘要
由于可以利用低品位热源制冷,氨水吸收式制冷系统得到了广泛的应用。氨水系统的精馏器要求很高的安装精度,限制了其应用范围。为了开发新型制冷器,将升膜理论应用到氨水吸收式制冷系统中,用一个冷凝发生器来实现精馏塔的作用。研究结果表明,本循环的热力系数比较高,这一成果可广泛应用于各种车、船等的制冷系统设计中。
The theory of rising film was applied to the NH3-H2O absorption refrigeration system. The function of the dephlegmator was realized by a condensation and generation device. The structure of the system was simplified dramatically, whereas the coefficient of performance （COP） was still comparably high. This conclusion can be widely applied to the refrigeration system on different kinds of vehicles and ships.
