【摘要】：针对吸附材料在太阳能吸附式制冷系统中的应用,利用称重法在高温真空环境下对水的脱附性能进行了实验研究,探究不同温度、压力对SAPO-34沸石分子筛脱附性能的影响.结果表明:温度对材料脱附性能的影响要远大于压力的影响,这在吸附式制冷系统中是非常有利的;当压力一定时,材料的脱附完善度随温度的升高而增大,且不随温度变化均匀分布.温度过高会影响SAPO-34的性能及影响材料的使用寿命;当温度一定时,材料的脱附完善度随着压力的降低而增大,其变化随压力变化分布得较为均匀.
[Abstract]:In view of the application of adsorption materials in the solar adsorption refrigeration system, the desorption properties of water in high temperature vacuum environment were studied by weighing method, and the effects of different temperatures and pressures on the desorption properties of SAPO-34 zeolite molecular sieve were investigated. The results show that the influence of temperature on the desorption performance of the material is much greater than that of the pressure, which is very advantageous in the adsorption refrigeration system, and when the pressure is constant, the desorption consummation of the material increases with the increase of temperature. And the distribution is not uniform with the change of temperature. The properties of SAPO-34 and the service life of SAPO-34 are affected by high temperature, and when the temperature is fixed, the degree of desorption of SAPO-34 increases with the decrease of pressure, and the variation of desorption perfection increases with the change of pressure.
