换热器对化学吸附式制冷系统的影响

摘要

The dynamic characteristics of the CaCl2-NH3 chemical adsorption refrigeration system driven by engine exhausted gas was studied. A thermal dynamic model is established to simulate the performanceofevaporation temperature, condensation temperature, evaporator and condenser outlet temperature in the running system and the article summarizes the varieties of system performance parameters in the different evaporation temperature and condensation temperature.Sothis result can provide a reference for the further research on the matching and optimization inthe chemical adsorption refrigeration system.%研究了内燃机尾气驱动的氯化钙-氨化学吸附式制冷系统的动态运行状况。通过建立热力学动态模型，仿真得到蒸发温度、冷凝温度、蒸发器与冷凝器出口温度在系统运行时的变化，并总结了在变蒸发温度或冷凝温度下系统性能参数的变化规律。结论可以为今后有关化学吸附式制冷系统各部件的匹配性和优化系统性能的进一步研究提供参考。
