The adsorber 300 includes a heat exchanger disposed within the adsorption chamber for providing cold or heat to the adsorbent within the adsorption chamber to cause the adsorbent to be adsorbed by and desorbed from the adsorbent within the adsorption chamber.
Exemplary adsorbents may include, but are not limited to, cooling water, cooling oil, and the like.
By way of example, the adsorbent may comprise one or more of the following: activated carbon, silica gel, metal organic frameworks (metal organic frameworks, MOF), activated alumina, and the like.
The adsorption refrigeration device 50 further includes a condenser 200, the condenser 200 has an inlet end and an outlet end, the condenser 200 includes a condensation chamber, the inlet end of the condenser 200 and the outlet end of the condenser 200 are both communicated with the condensation chamber, the inlet end of the condenser 200 is used for allowing the adsorbate to flow into the condensation chamber so as to make the adsorbate exothermically condense in the condensation chamber, and the outlet end of the condenser 200 is used for allowing the adsorbate condensed in the condensation chamber to flow out of the condensation chamber. The condenser 200 includes a cooling member disposed in the condensing chamber for absorbing heat from the adsorbate in the condensing chamber to exothermically condense the adsorbate in the condensing chamber.
The outlet end of the adsorber 300 is connected to the inlet end of the condenser 200 so that the adsorbate desorbed in the adsorption chamber may flow into the condensing chamber for condensation.
By way of example, the cooling member may include heat exchange tubes or the like for passing a heat exchange medium therethrough.
The adsorption refrigeration device 50 also includes an evaporator 100, the evaporator 100 having an inlet end and an outlet end. The evaporator 100 includes an evaporation cavity, an inlet end of the evaporator 100 and an outlet end of the evaporator 100 are both communicated with the evaporation cavity, the inlet end of the evaporator 100 is used for allowing the adsorbate to flow into the evaporation cavity so as to enable the adsorbate to absorb heat and evaporate in the evaporation cavity, and the outlet end of the evaporator 100 is used for allowing the adsorbate evaporated in the evaporation cavity to flow out of the evaporation cavity. The evaporator 100 includes a heat supply part provided in the evaporation chamber, and absorbs heat of the heat supply part when the liquid adsorbent in the evaporation chamber evaporates, so that the heat supply part can be used for cooling.
The outlet end of the condenser 200 is connected to the inlet end of the evaporator 100, so that the adsorbate condensed by the condenser 200 can flow into the evaporation chamber for evaporation.
By way of example, the heat supply means may comprise heat exchange tubes or the like for the flow of a heat exchange medium.
The adsorber 300 may alternately heat and cool the adsorbents in the adsorption chambers by alternately supplying a high temperature medium and a low temperature medium into the heat exchanger, so that the adsorbents in the adsorption chambers may alternately desorb and adsorb, the desorbed adsorbents may flow into the condensation chambers from the adsorption chambers, the adsorbents flowing into the condensation chambers from the adsorption chambers may enter the evaporation chambers after being condensed into a liquid state by the condenser 200 in the condensation chambers, and the evaporator 100 may evaporate the adsorbents in the liquid state in the evaporation chambers, thereby realizing refrigeration.
In order to enable continuous cooling of the evaporator 100, the adsorption refrigeration device 50 may include two adsorbers 300, and the outlet ends of the two adsorbers 300 are connected to the inlet end of the condenser 200, so that continuous cooling of the evaporator 100 may be achieved by alternately supplying the two adsorbers 300 with the adsorbent to the condenser 200. Specifically, when one of the two adsorbers 300 is desorbed to supply the adsorbent to the condenser 200, the other adsorber 300 is adsorbed to store the adsorbent, and when the desorption process of the desorbed adsorber 300 is completed or the adsorption process of the adsorbed adsorber 300 is completed, the currently desorbed adsorber 300 is switched to adsorb to store the adsorbent, and the currently adsorbed adsorber 300 is switched to desorb to supply the adsorbent to the condenser 200, so that the adsorbent is continuously supplied to the condenser 200, the adsorbent is continuously evaporated in the evaporation chamber, and the evaporator 100 is continuously cooled.
The inlet ends of the two adsorbers 300 may be connected to the outlet end of the evaporator 100, so that the gaseous adsorbent flowing out of the evaporation chamber may flow into the adsorption chamber of the adsorber 300 for adsorption to be adsorbed by the adsorbent, and thus, recycling of the adsorbent may be achieved.
Illustratively, the evaporating chamber, condensing chamber and adsorbing chamber may be in a negative pressure environment, which facilitates heated evaporation of the adsorbate.
In order to enable the adsorbent between the outlet end of the condenser 200 and the inlet end of the evaporator 100 to flow smoothly and stably into the evaporation chamber, the adsorption refrigeration device 50 may further include a first driving device 400 disposed between the outlet end of the condenser 200 and the inlet end of the evaporator 100, where the outlet end of the condenser 200 is connected to the inlet end of the evaporator 100 through the first driving device 400, and the first driving device 400 is used for driving the adsorbent at the inlet end of the first driving device 400 to flow toward the inlet end of the evaporator 100.
In this way, the adsorbate in the condensation chamber may flow to the inlet end of the evaporator 100 under the driving of the first driving device 400, after the adsorbate in the condensation chamber flows out, the pressure in the condensation chamber is reduced, and the adsorbate may be sucked into the condensation chamber from the outlet end of the adsorber 300 that performs desorption, so the arrangement positions of the evaporator 100, the condenser 200 and the adsorber 300 may be more flexible. In addition, the adsorbate flows relatively stably toward the inlet end of the evaporator 100 under the driving of the first driving device 400, so that the problem that the adsorbate is difficult to flow from the inlet end of the evaporator 100 due to the large pressure in the evaporation cavity is not easy to occur, and the problem that evaporation efficiency of the evaporator 100 is reduced due to the difficulty in flowing of the adsorbate is not easy to occur.
By way of example, the first drive means 400 may include, but is not limited to, a drive pump, a throttle valve, and the like. When the first driving device 400 is a driving pump, the driving pump may be a constant frequency pump or a variable frequency pump.
Illustratively, both the evaporator 100 and the condenser 200 are disposed below the adsorber 300. In this way, the adsorber 300 does not need to support the evaporator 100 and the condenser 200, so that the requirement on the structural strength of the adsorber 300 is low, and a door opening with a larger size is formed on the side surface of the adsorber 300, so that articles such as a heat exchanger, an adsorbent and the like can be assembled in the adsorption cavity. In addition, the spacing between the evaporator 100 and the condenser 200 and the bearing surface for supporting the adsorption refrigeration device 50 is smaller, and the requirement for structural strength of the portion of the adsorption refrigeration device 50 for supporting the evaporator 100 and the condenser 200 is lower, so that the number of structural members of the portion of the adsorption refrigeration device 50 for supporting the evaporator 100 and the condenser 200 is smaller, the thickness is thinner, and the size of the adsorption refrigeration device 50 is further reduced.
In the embodiment of the application, the heat exchanger is provided with an inlet end and an outlet end, the inlet end of the heat exchanger is used for flowing high-temperature medium or low-temperature medium into the heat exchanger, the medium flowing into the heat exchanger can be used for carrying out heat exchange with the adsorbate in the adsorption cavity, and the outlet end of the heat exchanger is used for flowing out of the heat exchanger after carrying out heat exchange with the adsorbate in the adsorption cavity.
The inlet end of the heat exchanger is connected with the outlet end of the heat supply equipment and the outlet end of the cold source equipment, the outlet end of the heat supply equipment is used for enabling the high-temperature medium to flow out of the heat supply equipment, the high-temperature medium flowing out of the outlet end of the heat supply equipment can flow into the heat exchanger through the inlet end of the heat exchanger, and the high-temperature medium flowing into the heat exchanger can provide heat for the adsorbent in the adsorption cavity so that the adsorbent is desorbed from the adsorbent. The outlet end of the cold source equipment is used for allowing the low-temperature medium to flow out of the cold source equipment, the low-temperature medium flowing out of the outlet end of the cold source equipment can flow into the heat exchanger through the inlet end of the heat exchanger, and the low-temperature medium flowing into the heat exchanger can provide cold for the adsorbate in the adsorption cavity so that the adsorbate is adsorbed by the adsorbate.
By way of example, the heating equipment may include, but is not limited to, liquid cooling equipment that is a hot water tank, a data center, and the like.

In some possible embodiments, the adsorbent comprises activated carbon.
In some examples, the specific surface area of the activated carbon is in a range of greater than or equal to 200m 2/g and less than or equal to 5000m 2/g.
Thus, the adsorption and desorption performance of the activated carbon to the adsorbate is better.
Illustratively, the specific surface area of the activated carbon is in the range of greater than or equal to 800m 2/g and less than or equal to 2000m 2/g.
Thus, the adsorption quantity of the activated carbon to the adsorbate is large, and the stability of the adsorbate after being adsorbed by the activated carbon is good.
In some examples, the pore size of the activated carbon is in a range of greater than or equal to 0.1nm and less than or equal to 50 nm.
Thus, the adsorption and desorption performance of the activated carbon to the adsorbate is better.

The adsorbent is less than or equal to 2mm, so that the adsorbent close to the surface of the heat exchanger 700 cannot be fully adsorbed due to the fact that the stacking thickness of the adsorbent is thicker when the adsorbent is adsorbed, the adsorbent far away from the surface of the heat exchanger 700 is difficult to desorb due to the fact that the stacking thickness of the adsorbent is thicker when the adsorbent is desorbed, and the efficiency of the adsorbent is higher when the adsorbent is adsorbed and desorbed.
