Abstract

The invention provides a multistage adsorption refrigeration method. The method comprises a first adsorption equipment and a second adsorption equipment, the first adsorption equipment and the secondadsorption equipment are provided with a first-stage adsorber, a second-stage adsorber and a third adsorber, wherein the first-stage adsorber, the second-stage adsorber and the third-stage adsorber are configured to be filled with porous adsorption materials; refrigerant pipes penetrate through the porous adsorption material particles, wherein the space rate between the particles of the porous adsorption materials in each adsorber is linearly increased relative to the pressure drop of the refrigerant pipes in the adsorption equipment, so that in the interior of the first adsorption equipment and the second adsorption equipment, the actual adsorption capacity of the adsorber at each stage is consistent in the refrigerant flow direction.

Description

technical field [0001] The present disclosure relates to a refrigerating device, in particular to an adsorption refrigerating device with cooling adsorption and heating desorption. Background technique [0002] With the continuous development of adsorption refrigeration systems, there are more and more types of improvements in adsorption refrigeration systems, including adsorption air conditioners / heat pumps, solar adsorption refrigerators, adsorption ice machines and so on. The metal heat capacity and fluid heat capacity of the adsorption refrigeration equipment have a great influence on the performance COP of the adsorption refrigeration system. [0003] The existing adsorption refrigeration system generally adopts two adsorption machines, one evaporator and one condenser, throttle valve and so on. When one adsorption device communicates with the condenser and is heating and desorbing, the other adsorption device communicates with the evaporator for cooling adsorption. A...
