| Abstract: | 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. |
