Abstract

A multi-stage adsorption refrigeration device, which includes a first adsorption device and a second adsorption device, the primary adsorber, the secondary adsorber, and the tertiary adsorber in the first and second adsorption devices are configured to be filled with porous adsorption material, the refrigerant pipe passes between the particles of the porous adsorption material, wherein the space ratio between the particles of the porous adsorption material in each adsorber increases linearly with respect to the pressure drop of the refrigerant pipe inside the adsorption device, so that the first 1. The interior of the second adsorption device moves upward along the refrigerant flow, and the adsorption capacity per unit time of the adsorbers at all levels is consistent.

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...
