The first heat exchange flow channel 120 is isolated from the evaporation cavity 110, and the evaporator 100 is configured to exchange heat between the medium in the first heat exchange flow channel 120 and the absorbent in the evaporation cavity 110, and absorb heat in the medium in the first heat exchange flow channel 120 when the absorbent in the liquid state in the evaporation cavity 110 evaporates. The evaporator 100 may be manufactured by introducing a high-temperature or normal-temperature medium into the first heat exchange flow passage 120. For example, the evaporator 100 may be made into cold water by supplying normal temperature water or high temperature water into the first heat exchange flow passage 120.

For example, cold water produced by the evaporator 100 may be used in a cold source device 30, a cooling device, or the like requiring cold to reduce energy consumption of a data center. Specifically, in some examples where the evaporator 100 has the first heat exchanging flow path 120, the first heat exchanging flow path 120 may be in communication with the cold source device 30, and the low temperature medium made of the evaporator 100 may be used to dissipate heat from the medium flowing back to the cold source device 30 after absorbing the heat.

In addition, the absorbent in the condensation chamber 210 may flow to the inlet end of the evaporator 100 under the driving of the first driving device 420, after the absorbent in the condensation chamber 210 flows out, the pressure in the condensation chamber 210 is reduced, the absorbent may be sucked into the condensation chamber 210 from the outlet end of the adsorber assembly 300, and the arrangement of the evaporator 100, the condenser 200 and the adsorber assembly 300 may be flexible.

The inlet end of the first adsorber 310 and the inlet end of the second adsorber 320 are connected to the outlet end of the evaporator 100 by a first reversing device 500. The outlet end of the first adsorber 310 and the outlet end of the second adsorber 320 are connected to the inlet end of the condenser 200 by a second reversing device 600. The first reversing device 500 is used to place the inlet end of the first adsorber 310 in communication with the outlet end of the evaporator 100 or the inlet end of the second adsorber 320 in communication with the outlet end of the evaporator 100.

The low-temperature medium flowing out of the cold source device 30 may be supplied to the first heat exchanger 311 or the second heat exchanger 321 so that the adsorbent in the first chamber 312 is adsorbed by the first adsorbent or the adsorbent in the second chamber 322 is adsorbed by the second adsorbent.

Specifically, when the first adsorber 310 adsorbs and the second adsorber 320 desorbs, the third reversing device 700 may be controlled to allow the low-temperature medium flowing out of the cold source device 30 to flow into the first heat exchanger 311 and the high-temperature coolant flowing out of the liquid cooling device 20 to flow into the second heat exchanger 321, the low-temperature medium flowing through the first heat exchanger 311 may reduce the temperature of the adsorbent in the first chamber 312 so that the adsorbent in the first chamber 312 is adsorbed by the first adsorbent, and the high-temperature coolant flowing through the second heat exchanger 321 may raise the temperature of the adsorbent adsorbed by the second adsorbent so that the adsorbent adsorbed by the second adsorbent is desorbed from the second adsorbent.

In some examples, the data center further includes a fourth reversing device 800. The outlet end of the first heat exchanger 311 and the outlet end of the second heat exchanger 321 are connected to the inlet end of the cold source device 30 and the inlet end of the liquid cooling device 20 through the fourth reversing device 800.

In this way, the directions of the media flowing out of the first heat exchanger 311 and the second heat exchanger 321 can be adjusted according to the sources of the media fed into the first heat exchanger 311 and the second heat exchanger 321, so that the cooling liquid flowing out of the liquid cooling device 20 can flow back into the liquid cooling device 20, and the media flowing out of the cold source device 30 can flow back into the cold source device 30, thereby facilitating the recycling of the cooling liquid in the liquid cooling device 20 and the media in the cold source device 30.

The coolant distribution device 40 may be used to dissipate the coolant in the third heat exchange flow path 41.

In this way, after the cooling liquid flowing out from the liquid cooling device 20 exchanges heat through the first heat exchanger 311 or the second heat exchanger 321, the cooling liquid can enter the cooling liquid distribution device 40 to further dissipate heat, so that the temperature of the cooling liquid flowing back to the liquid cooling device 20 meets the requirement of the liquid inlet temperature of the liquid cooling device 20.

That is, when the first valve 410 is closed, the liquid absorbent in the evaporation chamber 110 may flow out of the evaporation chamber 110 from the bypass outlet 111, and then flow into the evaporation chamber 110 from the inlet end of the evaporator 100, the liquid absorbent entering the evaporation chamber 110 from the inlet end of the evaporator 100 may flow along the surface of the heat supply member 130, and the liquid absorbent in the evaporation chamber 110 may maintain fluidity, so that the evaporation efficiency of the evaporator 100 may be high, and a problem of a decrease in the evaporation efficiency of the evaporator 100 caused by no inflow of the liquid absorbent from the inlet end of the evaporator 100 due to the closing of the first valve 410 may not occur easily. In addition, the bypass outlet 111 is located at a lower portion of the evaporation chamber 110 to facilitate control of the liquid level in the evaporation chamber 110.

In some possible embodiments, the evaporator 100 is located below the adsorber assembly 300 and the outlet end of the evaporator 100 is located at an upper portion of the evaporation chamber 110. In this manner, the adsorbent material vaporized within the vaporization chamber 110 is facilitated to flow from the outlet end of the vaporizer 100 into the adsorption chamber of the adsorber assembly 300 using its own lift force.

Where the adsorber assembly 300 includes a first adsorber 310 and a second adsorber 320, both the first adsorber 310 and the second adsorber 320 are positioned above the evaporator 100.

In some possible embodiments, the condenser 200 is located below the adsorber assembly 300, the inlet end of the condenser 200 is located at an upper portion of the condensing chamber 210, and the outlet end of the condenser 200 is located at a lower portion of the condensing chamber 210.

Thus, the inlet end of the condenser 200 is positioned at the upper portion of the condensing chamber 210, and the outlet end of the condenser 200 is positioned at the lower portion of the condensing chamber 210, so that the liquid level in the condenser 200 can be controlled. In addition, the condenser 200 is positioned below the adsorber assembly 300 without the need for a support member having a relatively high height and relatively strong structural strength to support the condenser 200.

In some possible embodiments, the adsorption refrigeration system further includes a first conduit 430, the first conduit 430 having a first port, a second port, and a third port. The outlet end of the first valve 410 is connected to the first port, and the inlet end of the first driving device 420 is connected to the second port, such that the outlet end of the first valve 410 is connected to the inlet end of the first driving device 420 through the first pipe 430, and the bypass outlet 111 is connected to the third port, such that the bypass outlet 111 is connected to the inlet end of the first driving device 420 through the first pipe 430.

This facilitates connecting the first valve 410, the first drive 420 and the bypass outlet 111.

In some possible embodiments, the adsorption refrigeration system further includes a second valve 440, the first pipeline 430 further has a fourth port, the fourth port is provided with the second valve 440, and the second valve 440 is used for controlling on-off of the flow path of the fourth port.

In this way, when the amount of the adsorbent in the adsorption refrigeration system is too small, the fourth port can be used for supplementing, and when the amount of the adsorbent in the adsorption refrigeration system is too large, the adsorbent in the adsorption refrigeration system can be discharged through the fourth port, so that the amount of the adsorbent in the adsorption refrigeration system can be conveniently adjusted.

In some possible embodiments, the first valve 410 may be an on-off valve.

In some possible embodiments, the first valve 410 may be a flow regulating valve, the first valve 410 also being used to regulate the flow of adsorbate from the condenser 200 to the evaporator 100.

In some possible embodiments, the evaporator 100 further comprises a spray member 140, at least a portion of the spray member 140 being disposed within the evaporation cavity 110 of the evaporator 100. The outlet end of the first valve 410 is connected to the inlet end of the spraying part 140, and the spraying part 140 is used to spray the adsorbate toward the heating part 130.

Thus, a large contact area between the liquid adsorbent flowing in from the inlet end of the evaporator 100 and the heat supply member 130 can be provided, and the evaporation efficiency of the evaporator 100 can be made high.

In the example where the adsorption refrigeration system further includes a first drive 420, the inlet end of the spray member 140 is coupled to the outlet end of the first drive 420 such that the inlet end of the spray member 140 is coupled to the outlet end of the first valve 410 via the first drive 420.

When the evaporator 100 has a bypass outlet 111, the inlet end of the shower member 140 is also connected to the bypass outlet 111 by a first drive 420.

Illustratively, the spray assembly may include a plurality of spray heads 141, each spray head 141 having an inlet end connectable to an outlet end of the first valve 410 via the second conduit 450.

Fig. 5 is a schematic diagram of another adsorption refrigeration system according to an embodiment of the present application.

As shown in fig. 5, in some possible embodiments, a first liquid level detection device 920 is disposed in the evaporation chamber 110 of the evaporator 100, and the adsorption refrigeration device 60 includes the first liquid level detection device 920. The first liquid level detection device 920 is used for detecting the liquid level in the evaporation chamber 110. In this way, the level of the liquid in the evaporation chamber 110 is easily grasped in real time, so that the first valve 410 is controlled according to the level of the liquid in the evaporation chamber 110.

In some possible embodiments, the adsorption refrigeration system further includes a controller 910, wherein the first liquid level detection device 920 and the first valve 410 are electrically connected to the controller 910, and the controller 910 can control the first valve 410 according to the liquid level detected by the first liquid level detection device 920.

In some possible embodiments, the first driving device 420 is electrically connected to the controller 910, and the controller 910 may control the first driving device 420 according to the liquid level detected by the first liquid level detecting device 920.

In some possible embodiments, a second liquid level detection device 930 is disposed in the condensation chamber 210 of the condenser 200, and the second liquid level detection device 930 is configured to detect a liquid level in the condensation chamber 210. In this way, the liquid level in the condensing chamber 210 is conveniently grasped in real time, so that the first valve 410 is controlled according to the liquid level in the condensing chamber 210.

For example, a first threshold, a second threshold, a third threshold, and a fourth threshold may be set, the first threshold being greater than the third threshold, the second threshold being less than the fourth threshold. When the liquid level detected by the first liquid level detecting device 920 is greater than or equal to the first threshold value, and the liquid level detected by the second liquid level detecting device 930 is less than or equal to the second threshold value, the first valve 410 may be controlled to be closed, and the first driving device 420 may drive the liquid absorbent in the evaporation cavity 110 to flow out of the evaporation cavity 110 from the bypass outlet 111 and flow out of the evaporation cavity 110 to the inlet end of the evaporator 100, so that after a period of time, the liquid level in the evaporation cavity 110 may be reduced, and the liquid level in the condenser 200 may be increased. When the liquid level detected by the first liquid level detecting device 920 is less than the first threshold and greater than or equal to the third threshold, and the liquid level detected by the second liquid level detecting device 930 is greater than the second threshold and less than or equal to the fourth threshold, the first valve 410 may be controlled to be opened, and the condenser 200 may deliver the liquid absorbent for evaporation to the evaporator 100. The first alarm may be issued when the liquid level detected by the first liquid level detection device 910 is greater than a first threshold, the liquid level detected by the second liquid level detection device 920 is greater than a fourth threshold, and the second alarm may be issued when the liquid level detected by the first liquid level detection device 920 is less than a third threshold, and the liquid level detected by the second liquid level detection device 930 is less than a second threshold.

Specifically, the controller 910 is configured to obtain a first liquid level and a second liquid level, where the first liquid level is the liquid level detected by the first liquid level detecting device 920, and the second liquid level is the liquid level detected by the second liquid level detecting device 930. When the first level is greater than or equal to the first threshold and the second level is less than or equal to the second threshold, the first valve 410 is controlled to close.

In this way, when the liquid level in the evaporation cavity 110 is too high and the liquid level in the condensation cavity 210 is too low, the flow path between the evaporation cavity 110 and the condensation cavity 210 can be cut off, so that the adsorbate in the condensation cavity 210 cannot flow into the evaporation cavity 110, and the adsorbate in the evaporation cavity 110 can continue to evaporate, so as to adjust the liquid levels in the evaporation cavity 110 and the condensation cavity 210.

In some examples, the controller 910 is further configured to control the first valve 410 to open when the first liquid level is greater than or equal to a third threshold and less than the first threshold, and the second liquid level is greater than a second threshold and less than or equal to a fourth threshold.

In this way, when the liquid level in the evaporation chamber 110 is too low and the liquid level in the condensation chamber 210 is too high, the flow path between the evaporation chamber 110 and the condensation chamber 210 is communicated, so that the adsorbate in the condensation chamber 210 can flow into the evaporation chamber 210, and the liquid levels in the evaporation chamber 110 and the condensation chamber 210 can be adjusted. In this way, the liquid levels in the evaporating chamber 110 and the condensing chamber 210 can be controlled within a reasonable range, which is beneficial to keeping the evaporating efficiency of the evaporator 100 high.

In some examples, the controller 910 is further configured to issue a first alarm command when the first liquid level is greater than a first threshold and the second liquid level is greater than a fourth threshold.

For example, the first alarm instruction may be used to control the audible and visual alarm, the display screen, and the like, where the alarm device operates in the first operation mode, and the display screen may be a display screen of the control device. For example, the first alarm instruction may be used to control the audible and visual alarm to emit a first preset audible and visual, and the first alarm instruction may also be used to control the display screen to display a first preset image.

In this way, a fault may be alerted when an internal leak of the evaporator 100, condenser 200, adsorber assembly 300, etc. occurs, resulting in increased media in the evaporator chamber 110, condenser chamber 210, and adsorber chamber, etc.

In some examples, the controller 910 is further configured to issue a second alarm command when the first liquid level is less than a third threshold and the second liquid level is less than a second threshold.

For example, the second alarm instruction may be used to control the audible and visual alarm, the display screen, etc. of the alarm device to operate according to the second operation mode, where the display screen may be a display screen of the control device. For example, the second alarm instruction may be used to control the audible and visual alarm to emit a second preset audible and visual, and the first alarm instruction may also be used to control the display screen to display a second preset image.

Thus, a fault may be alerted when a problem arises in that the evaporator 100, condenser 200, adsorber assembly 300, etc., leaks outwardly, resulting in a reduction of media in the evaporator chamber 110, condenser chamber 210, and adsorber chamber, etc.

Thus, the seventh valve 720, the eighth valve 730, the fifth heat exchange flow channel 3111 and the seventh heat exchange flow channel 3211 are used for flowing the medium from the cold source device 30, the ninth valve 740, the tenth valve 750, the sixth heat exchange flow channel 3112 and the eighth heat exchange flow channel 3212 are used for flowing the cooling liquid from the liquid cooling device 20, and the medium from the cold source device 30 and the cooling liquid from the liquid cooling device 20 have independent flow channels respectively, so that the cooling liquid from the liquid cooling device 20 and the medium from the cold source device 30 are not easy to pollute each other at the third reversing device 700. The seventh valve 720 and the eighth valve 730 may be used to control the flow of the medium from the cold source device 30 to the fifth heat exchange flow channel 3111 or the seventh heat exchange flow channel 3211 to enable the adsorbent in the first chamber 312 to be adsorbed by the first adsorbent or the adsorbent in the second chamber 322 to be adsorbed by the second adsorbent, and the ninth valve 740 and the tenth valve 750 may be used to control the flow of the cooling liquid from the liquid cooling device 20 to the sixth heat exchange flow channel 3112 or the eighth heat exchange flow channel 3212 to enable the desorption of the adsorbent adsorbed by the first adsorbent in the first chamber 312 or the adsorbent adsorbed by the second adsorbent in the second chamber 322, so as to implement the adsorption and desorption of the first adsorber 310 and the second adsorbent alternately.

In some examples, the fourth reversing device 800 includes an eleventh valve 820, a twelfth valve 830, a thirteenth valve 840, and a fourteenth valve 850.

An inlet end of the fourteenth valve 850 is communicated with an outlet end of the eighth heat exchanging channel 3212, and an outlet end of the fourteenth valve 850 is used for communicating with an inlet end of the liquid cooling apparatus 20.

In this way, the eleventh valve 820, the thirteenth valve 840, the fifth heat exchange flow channel 3111 and the seventh heat exchange flow channel 3211 are used for flowing the medium from the cold source device 30, the twelfth valve 830, the fourteenth valve 850, the sixth heat exchange flow channel 3112 and the eighth heat exchange flow channel 3212 are used for flowing the cooling liquid from the liquid cooling device 20, and the medium from the cold source device 30 and the cooling liquid from the liquid cooling device 20 have independent flow channels, respectively, so that the cooling liquid from the liquid cooling device 20 and the medium from the cold source device 30 are not easy to pollute each other at the fourth reversing device 800. When the medium from the cold source device 30 flows through the fifth heat exchange flow channel 3111 and the cooling liquid from the liquid cooling device 20 flows through the eighth heat exchange flow channel 3212, the medium flowing out of the fifth heat exchange flow channel 3111 may be returned to the cold source device 30 and the cooling liquid flowing out of the eighth heat exchange flow channel 3212 may be returned to the liquid cooling device 20 by opening the eleventh valve 820 and the fourteenth valve 850 and closing the twelfth valve 830 and the thirteenth valve 840. When the medium from the heat sink device 30 flows through the seventh heat exchange flow channel 3211 and the cooling liquid from the liquid cooling device 20 flows through the sixth heat exchange flow channel 3112, the medium flowing out of the seventh heat exchange flow channel 3211 may be returned to the heat sink device 30 and the cooling liquid flowing out of the sixth heat exchange flow channel 3112 may be returned to the liquid cooling device 20 by opening the twelfth valve 830 and the thirteenth valve 840 and closing the eleventh valve 820 and the fourteenth valve 850. The eleventh valve 820, the twelfth valve 830, the thirteenth valve 840 and the fourteenth valve 850 can control the direction of the medium flowing out of the first heat exchanger 311 and the second heat exchanger 321, so that the cooling liquid flowing out of the liquid cooling device 20 can flow back into the liquid cooling device 20, and the medium flowing out of the cold source device 30 can flow back into the cold source device 30, thereby facilitating the recycling of the cooling liquid in the liquid cooling device 20 and the medium in the cold source device 30.

In this way, the cooling liquid from the liquid cooling apparatus 20 and the medium from the cold source apparatus 30 have the flow channels that are independent from each other in the process of alternately adsorbing and desorbing the first adsorber 310 and the second adsorber 320, respectively, so that the cooling liquid from the liquid cooling apparatus 20 and the medium from the cold source apparatus 30 are not likely to be contaminated with each other, and the restriction on the type selection of the cooling liquid flowing out of the liquid cooling apparatus 20 and the medium flowing out of the cold source apparatus 30 is small. At this time, the cooling liquid flowing out of the liquid cooling apparatus 20 and the medium flowing out of the cold source apparatus 30 may be different mediums, for example, the cooling liquid flowing out of the liquid cooling apparatus 20 may be a fluorinated liquid, and the medium flowing out of the cold source apparatus 30 may be water. Of course, the cooling liquid flowing out of the liquid cooling device 20 and the medium flowing out of the cold source device 30 may be the same medium, for example, both the cooling liquid flowing out of the liquid cooling device 20 and the medium flowing out of the cold source device 30 may be water, so that the standard of the water flowing out of the liquid cooling device 20 is higher than that of the water flowing out of the cold source device 30, and thus the liquid cooling device 20 is not easy to be blocked, and the cost of the medium used in the cold source device 30 is low.
