Abstract

The invention discloses a multi-level adsorption refrigerating appliance, which comprises a box body with a first level adsorption device, a second adsorption device and a third adsorption device. Thestructures of porous adsorbent material of the three adsorption devices all meet the following relationship: the space rate is from K 1-level to K 3-level along the flow direction of the refrigerantrelative to the pressure drop of the refrigerant in the refrigerating appliance, which is increased linearly, so that the inside porous adsorbent material of the appliance is directed upward along theflow of the refrigerant, and the adsorption capacity per unit time of the porous adsorbent is consistent.

Description

technical field [0001] The disclosure relates to a refrigeration device, in particular to a multi-stage adsorption refrigeration appliance 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 adsorpti...
