Technical Field

The invention relates to the technical field of adsorption refrigeration, in particular to an adsorption refrigeration system and method capable of transferring adsorption materials.

Background

At present, an adsorption refrigeration system mainly comprises an adsorption bed, an evaporator, a condenser, an adsorption working medium pair and a circulating pipeline. When the adsorption refrigeration system operates, the adsorption beds are alternately heated and cooled, so that the adsorption material which is filled in the adsorption beds and is saturated in adsorption is desorbed to form a refrigerant, the high-temperature adsorption material which is completed in desorption is cooled for adsorption, and further, pressure difference is generated between the adsorption beds and the condenser and the evaporator to drive the refrigerant to flow in the pipeline, thereby generating the refrigeration effect.

Since the adsorption refrigeration system of either positive pressure or negative pressure requires good sealing properties, the adsorption bed is mostly made of metal, and therefore has a large heat capacity. On one hand, while the adsorption material is heated and cooled alternately, the adsorption bed is continuously heated and cooled alternately, the heat capacity of the adsorption bed made of metal is large, and large heat loss is generated; on the other hand, the adsorption bed for fixing the adsorbent is difficult to cooperatively optimize the heat transfer and mass transfer performance, the larger heat transfer and mass transfer resistance can prolong the adsorption and desorption periods, and the utilization efficiency of a heat source required during desorption and a cold source required during adsorption is reduced; although the surface coating type adsorption bed can reduce the heat and mass transfer resistance of the adsorption bed, the smaller loading amount of the adsorption material can limit the refrigerating capacity of the system and increase the volume of the adsorption bed.
