摘　　要：根据非平衡吸附条件下系统的动态方程计算了系统各参数的动态变化规律 ,并与实验值进行了对比 ,验证了理论模型的正确性 ,同时通过计算确定了吸附床传热系数、吸附床滞留传热介质量、吸附床加热与冷却介质热容、热源温度、冷却水温度、循环周期等对连续回热型吸附式空调 /热泵系统运行 p -t-x图的影响以及它们对系统运行SCP与COP的影响 ,分析了产生这些影响的机理 。By calculation of the system dynamic equations under non-balance adsorption condition, such curves as curve of adsorber temperature vs time, curve of condensing temperature vs time, curve of momentary refrigeration power vs time and p-t-x curve of adsorber are obtained. The calculation models are verified after these curves are compared with experimental data. According to calculation result, influences of some design parameters, which include heat transfer coefficient, mass of heating and cooling medium inside adsorber, specific heat of heat and cooling medium, on p-t-x diagram, SCP and COP are discussed, and the mechanism of the influences is analyzed. In addition,such operating parameters affecting p-t-x diagram as heat source temperature, cooling water temperature and cycle time, are also discussed. The work has laid a foundation for optimum operation and optimum design of a continuous heat recovery adsorption air-conditioning system/heat pump.
