Abstract
Description
Technical Field
[0001] This invention relates to the field of adsorption refrigeration technology, and more specifically, to an adsorption refrigeration device. Background Technology
[0002] An adsorption-type refrigeration device comprises an adsorbent and an adsorbent working fluid, and has a heat source fluid inlet, a chilled fluid inlet, and a cooling fluid inlet. During operation, the heat source fluid inlet introduces heat source fluid to heat the adsorbent, causing the adsorbent working fluid to desorb from the adsorbent. When the adsorbent working fluid needs to be reused, the cooling fluid inlet introduces cooling fluid to absorb heat from the desorbed gaseous adsorbent, causing it to re-condense into a liquid adsorbent. After desorption is complete, the cooling fluid inlet introduces cooling fluid into the adsorbent, cooling it to enable it to adsorb the remaining gaseous adsorbent, thus promoting the continuous evaporation of the liquid adsorbent. Meanwhile, the fluid introduced through the chilled fluid inlet releases heat to the evaporating liquid working fluid, resulting in chilled water at a lower temperature.
[0003] In practical applications, temperature fluctuations are common in loads that generate heat source fluids. This causes fluctuations in the heat flux of the supplied heat source fluids. Once fluctuations occur, they will affect the cooling effect of the adsorption refrigeration system, resulting in insufficient heat utilization and even a decrease in thermal efficiency.
[0004] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: heat source fluctuations lead to fluctuations in the heat flux of the heat source fluid, which in turn affects the heat utilization efficiency of the adsorption refrigeration system. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to provide an adsorption refrigeration device that can effectively solve the problem of poor refrigeration effect caused by poor adaptability of adsorption refrigeration system.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An adsorption refrigeration device, comprising:
[0008] Multiple adsorption refrigeration modules are provided, each including a heat source inlet, an adsorption bed, and a bed evaporator. The adsorption chamber of the adsorption bed is provided with an adsorbent to exchange heat with a heat exchange channel. The heat source inlet is used to supply heat source fluid to the heat exchange channel. The evaporation chamber of the bed evaporator is used to supply gaseous adsorbent to the adsorption chamber. The bed evaporator is provided with a refrigeration fluid channel to exchange heat with the liquid adsorbent in the evaporation chamber.
[0009] A heat source supply port is used to supply heat source fluid to the heat source inlet port so that the adsorption refrigeration module can work in the refrigeration mode.
[0010] The first control valve is used to change the number of adsorption refrigeration modules supplied by the heat source supply port.
[0011] In operation, the heat source inlet is connected to the heat source load to obtain the heat source fluid. The heat source fluid or the heat source load is then monitored. When the heat flux is low, the first control valve ensures that only a portion of the fluid from the heat source inlet enters the adsorption refrigeration modules for adsorption refrigeration, thus stabilizing the desorption phase time of these modules and ensuring the adsorption refrigeration effect. As the heat flux increases, the first control valve further controls the flow of fluid from the heat source inlet into more adsorption refrigeration modules, again stabilizing the desorption phase time and ensuring the adsorption refrigeration effect. This adsorption refrigeration device incorporates multiple adsorption refrigeration modules. During operation, the first control valve selects the appropriate number of modules to operate based on the heat flux from the heat source inlet, ensuring stable desorption phase time for the modules involved in the adsorption refrigeration process. This effectively avoids instability in adsorption refrigeration and prevents poor performance due to insufficient desorption and / or adsorption. In summary, this adsorption refrigeration device can effectively solve the problem of poor refrigeration effect caused by poor adaptability of adsorption refrigeration systems.

[0039] This invention discloses an adsorption refrigeration device that can effectively solve the problem of poor refrigeration effect caused by poor adaptability of adsorption refrigeration systems.
[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] Please see Figures 1-3 , Figure 1 This is a schematic diagram showing the connections of the various components of the adsorption refrigeration device provided in an embodiment of the present invention; Figure 2 for Figure 1 Enlarged structural diagram at point A in the diagram; Figure 3 for Figure 1 A magnified structural diagram at point B in the diagram.
[0042] In some embodiments, an adsorption refrigeration device is provided. Specifically, the adsorption refrigeration device includes an adsorption refrigeration module 1, a heat source supply port 9, and a first control valve 11.
[0043] Each adsorption-refrigeration module 1 is an adsorption unit, meaning it contains an adsorption-refrigeration system. Each module utilizes the heat pump effect of the introduced heating fluid to cool the introduced fluid to be refrigerated, thus obtaining a chilled fluid. Generally, an adsorption-refrigeration module 1 includes at least an adsorption bed 1-2 and an evaporator. A condenser may also be included for the recycling of the adsorbed working fluid. It should be noted that the specific interconnections between the components within the adsorption-refrigeration module 1 are not limited and can refer to existing technologies, such as mass return circulation and heat wave circulation adsorption-refrigeration systems. Specifically, the adsorption-refrigeration module 1 mainly includes a heat source inlet 1-1, an adsorption bed 1-2, and a bed evaporator 1-3.
[0044] The adsorption chamber 1-5 of the adsorption bed 1-2 is equipped with an adsorbent, and the working fluid used in conjunction with the adsorbent can flow through the adsorption chamber 1-5, the condensation chamber of the condenser, and the evaporation chamber 1-6 of the evaporator. The working fluid and the adsorbent combine to form a working fluid pair. In an adsorption refrigeration system, multiple sets of working fluid pairs can be set up. One adsorbent can correspond to multiple working fluids, or multiple adsorbents can correspond to one working fluid.
[0045] For adsorption bed 1-2, there are two main working states: adsorption and desorption, which are generally carried out in stages. In the adsorption state, a cryogenic fluid is used to cool adsorption bed 1-2, allowing the adsorbent within 1-2 to adsorb the gaseous working medium, ensuring continuous adsorption capacity in adsorption chamber 1-5 until the adsorbent reaches a preset saturation state. Taking physical adsorption as an example, the gaseous working medium liquefies into a liquid state, maintaining a low-pressure state within adsorption chamber 1-5 to continuously draw in gaseous working medium, such as continuously adsorbing the gaseous working medium from bed evaporator 1-3, thus enabling continuous evaporation and heat absorption in bed evaporator 1-3. In the desorption state, the adsorption bed is typically heated by a high-temperature fluid to 1-2, causing the adsorbent in the adsorbent to desorb from the adsorbent and re-form into a gaseous adsorbent. The gaseous adsorbent enters the condenser, where it is liquefied into a liquid adsorbent. Alternatively, the adsorbent can be discharged to the outside.
[0046] The adsorption bed 1-2 has a heat exchange channel 1-4 for heat exchange with the adsorbent in the adsorption chamber 1-5. This heat exchange channel 1-4 is a channel capable of carrying at least a high-temperature fluid (heat source fluid) during the desorption phase of the adsorption bed 1-2. During the adsorption phase, the heat exchange channel 1-4 can be closed or used to carry a low-temperature fluid. The heat exchange channel 1-4 can exchange heat with the adsorbent, ensuring that during the desorption phase, a high-temperature fluid flows through it, keeping the adsorption chamber 1-5 at a high temperature. After absorbing heat, the adsorbent desorbs a gaseous adsorbent, which absorbs heat from the high-temperature fluid in the heat exchange channel 1-4. This gaseous adsorbent can be discharged to the outside or into the condenser chamber of the condenser, where it is condensed back into a gaseous state. It should be noted that a heat exchange channel 1-4 can be set up to alternately circulate high-temperature fluid and low-temperature fluid; or a heat exchange channel 1-4 can be set up specifically for low-temperature fluid, while another channel can be set up specifically for high-temperature fluid; or only a heat exchange channel 1-4 for high-temperature fluid can be set up, and the adsorption stage of the adsorption bed 1-2 is not through the fluid, but through other heat-conducting structures, such as metal heat-conducting components, for heat dissipation.
[0047] The bed evaporator 1-3 is the evaporator of the adsorption bed 1-2 system. The evaporation chamber 1-6 of the bed evaporator 1-3 supplies gaseous adsorbent to the adsorption chamber 1-5. It also includes a chilled fluid channel 1-7 capable of exchanging heat with the liquid adsorbent in the evaporation chamber 1-6. The chilled fluid channel 1-7 can directly penetrate the evaporation chamber 1-6 for direct heat exchange through the pipe wall, or it can utilize a heat exchange system. During operation, the chilled fluid introduced through the chilled fluid channel 1-7 transfers heat to the liquid adsorbent in the evaporation chamber 1-6. The liquid adsorbent evaporates into a gaseous state, carrying away the heat. The gaseous adsorbent enters the adsorption chamber 1-5, releases heat there, and is absorbed by the adsorbent in the chamber. The released heat is then absorbed and dissipated through a heat transfer conductor or fluid.
[0048] The heat source supply port 9 is generally used to supply heat source fluid from the heat source load to the heat exchange channels 1-4. It also generally includes a heat source outlet 10, which is used to supply heat source fluid to the heat source load. In use, the heat source supply port 9 is connected to the heat source channel of the heat source load, and the heat source outlet 10 is connected to the aforementioned heat source channel. The fluid flowing out of the heat source outlet 10 enters the heat source channel, where it obtains heat from the heating element of the heat source load to raise its temperature, and then is discharged into the heat source supply port 9.
[0049] The heat source supply port 9 supplies heat source fluid to the heat source inlet 1-1 to enable the adsorption refrigeration module 1 to operate. If heat source fluid is continuously introduced into the heat source inlet 1-1 of the adsorption refrigeration module 1 through the heat source supply port 9, the adsorption refrigeration module 1 will operate continuously. Since the adsorption beds 1-2 need to alternate between desorption and adsorption, at least two adsorption beds 1-2 are typically provided to allow for alternating desorption and adsorption, thereby achieving continuous heat utilization and continuous refrigeration.
[0050] The first control valve 11 is used to change the number of adsorption-cooling modules 1 supplied by the heat source supply port 9, so that different numbers of adsorption-cooling modules 1 can be selected to operate as needed, such as selecting some or all of the adsorption-cooling modules 1 to operate. Specifically, when the heat flux supplied by the heat source supply port 9 is relatively large, more adsorption-cooling modules 1 are selected to operate; and when the heat flux supplied by the heat source supply port 9 is relatively small, fewer adsorption-cooling modules 1 are selected to operate. The first control valve 11 can have at least a first control state and a second control state. The number of adsorption-cooling modules 1 connected to the heat source supply port 9 when the first control valve 11 is in the first control state is different from the number of adsorption-cooling modules 1 connected to the heat source supply port 9 when the first control valve 11 is in the second control state. Specifically, the first control valve 11 can be a multi-way valve, with its inlet connected to the heat source supply port 9 and its outlet connected to each heat source inlet 1-1. The number of outlets connected to the inlet can be adjusted. The first control valve 11 can also include multiple switching valves, which can be set at each heat source inlet 1-1 or at the heat source outlet 1-16 to prevent the heat source fluid from flowing out. The heat source inlet 1-1 cannot enter the heat source fluid, thus preventing the heat source fluid from entering the adsorption refrigeration module 1 and preventing the adsorption refrigeration module 1 from performing adsorption refrigeration.
[0051] In use, the heat source inlet 1-1 is connected to the heat source load to obtain the heat source fluid. Then, the heat source fluid or the heat source load is monitored. When the heat flux is low, the first control valve 11 controls the fluid from the heat source supply port 9 to enter only a portion of the adsorption refrigeration module 1 for adsorption refrigeration, so as to better stabilize the desorption phase time of this portion of the adsorption refrigeration module 1 and ensure the adsorption refrigeration effect. As the heat flux increases, the first control valve 11 controls the fluid from the heat source supply port 9 to enter more of the adsorption refrigeration module 1 for adsorption refrigeration, so as to better stabilize the desorption phase time of this portion of the adsorption refrigeration module 1 and ensure the adsorption refrigeration effect. In the aforementioned adsorption refrigeration device, multiple adsorption refrigeration modules 1 are configured. During operation, the number of adsorption refrigeration modules 1 can be selected via the first control valve 11 based on the heat flux of the heat source fluid at the heat source supply port 9. This ensures a stable desorption phase for the adsorption refrigeration modules 1, effectively preventing instability in adsorption refrigeration and avoiding poor performance caused by insufficient desorption and / or adsorption by the adsorption refrigeration modules 1. In summary, this adsorption refrigeration device effectively solves the problem of poor cooling effect due to poor adaptability of adsorption refrigeration systems.
[0052] In some embodiments, a controller may also be included, which may be used to control the first control valve 11 to switch its operating state according to the heat flux of the heat source supply port 9 so as to change the number of adsorption cooling modules 1 supplied by the heat source supply port 9.
[0053] In some embodiments, considering that a larger number of adsorption refrigeration modules 1 provides better adaptability, the cost increases significantly. Therefore, only two, four, eight, or ten adsorption refrigeration modules 1 can be provided. The optimal heat flux of different adsorption refrigeration modules 1 can be the same or different. If they are different, different superimposed heat fluxes should be possible to adapt to changes in the heat flux of the heat source supply port 9, thus achieving adjustment. As shown in the attached figure, four adsorption refrigeration modules 1 are provided in parallel. Taking the optimal heat flux of a single adsorption refrigeration module 1 as Q, since the adsorption refrigeration device is provided with a total of four adsorption refrigeration modules 1, the maximum heat flux of the adsorption refrigeration device is 4Q (four times Q). At this time, if the heat flux supplied by the heat source supply port 9 is 4Q, then all four adsorption refrigeration modules 1 are turned on simultaneously; if the heat flux supplied by the heat source supply port 9 is 3Q, then three adsorption refrigeration modules 1 are turned on simultaneously; if the heat flux supplied by the heat source supply port 9 is 2Q, then two adsorption refrigeration modules 1 are turned on simultaneously; if the heat flux supplied by the heat source supply port 9 is Q, then one adsorption refrigeration module 1 is turned on.
[0054] How to determine the heat flux supplied by heat source supply port 9? Since heat flux is related to flow rate and temperature, it can be determined by combining flow rate and temperature. For the fluid supplied by heat source supply port 9: if the temperature remains constant but the flow rate changes, the flow rate can be used as the metric; if the flow rate remains constant but the temperature changes, the temperature can be used as the metric. Generally, the temperature of heat source supply port 9 can be kept constant by controlling the flow rate of the heat source load.
[0055] In the above control method, if the heat flux supplied by the heat source supply port 9 is 3.5Q, the excess 0.5Q heat flux can be discarded, and 3 adsorption refrigeration modules 1 can be turned on; or 0.5Q heat flux can be supplemented by other energy-consuming heat replenishment devices, so that a total heat flux of 4Q can be obtained, and 4 adsorption refrigeration modules 1 can still be turned on.
[0056] In some embodiments, an energy-consuming heat replenishment device may also be provided, such as an electric heating device, a compression refrigeration device, or other heat-generating device. In this case, the heat replenishment fluid outlet of the energy-consuming heat replenishment device supplies heat replenishment fluid to the corresponding heat source inlet 1-1 through the first control valve 11 to replenish the remaining heat flux to meet the usage requirements. The replenished heat flux is generally no greater than 1Q. Of course, if the total cooling capacity of the adsorption refrigeration module 1 is insufficient, the heat flux replenished by the energy-consuming heat replenishment device can be greater than 1Q.
[0057] In some embodiments, the heat replenishment channel and the heat source supply port 9 in the energy-consuming heat replenishment device can be connected in series or in parallel. In a series connection: the heat source fluid introduced through the heat source supply port 9 passes through the heat replenishment channel again to increase its temperature, and then enters the corresponding heat source inlet 1-1 under the action of the first control valve 11 to replenish the heat flux, thus ensuring the stability of the heat flux. In a parallel connection: one part of the heat source fluid enters through the heat source supply port 9, and another part of the heat source fluid is heated through the heat replenishment channel before entering. The two parts of the heat source fluid converge to increase the heat flux, and then enter the corresponding heat source inlet 1-1 under the action of the first control valve 11 to replenish the heat flux, thus ensuring the stability of the heat flux.
[0058] In some embodiments, the heat replenishment channel of the energy-consuming heat replenishment device can be connected in series between the heat source supply port 9 and the heat source inlet port 1-1, so that the heat source fluid entering through the heat source supply port 9 first enters the heat replenishment channel, is heated, and then supplied to the corresponding heat source inlet port 1-1. If the first control valve 11 is located between the heat source inlet port 1-1 and the heat source supply port 9, then the heat replenishment channel can be connected in series between the first control valve 11 and the heat source supply port 9; if the first control valve 11 is located behind the heat source outlet port 1-16, then the heat replenishment channel can be connected to each heat source supply port 9 through a multi-port structure.
[0059] In some embodiments, considering that in practical applications, the heat provided by the heat source fluid and the resulting cooling capacity may never meet the cooling requirements of the object being cooled, a compression refrigeration system 2 is required. In this case, the heating element of the compression refrigeration system 2 can generate heat and supply it to the adsorption bed 1-2 to help cool the adsorption bed 1-2. In this scenario, the compression refrigeration system 2 can be considered an energy-consuming heat replenishment device.
[0060] The compression refrigeration system 2 mainly includes a heat-receiving passage 2-6 and a heat-dissipating passage 2-8, and also needs to include a compressor 2-1, a throttling device 2-3, etc. The heat-receiving passage 2-6 is used to absorb heat from the fluid compressed by the compressor 2-1, thereby raising the internal temperature of the fluid. The heat-receiving passage 2-6 can be located outside the casing of the compressor 2-1. The compressed refrigerant will heat up and transfer heat to the casing of the compressor 2-1. Alternatively, the heat-receiving passage 2-6 can also obtain heat from the condenser of the compression refrigeration system 2. The high-temperature compressed refrigerant will enter the condenser, and the heat-receiving passage 2-6 can directly exchange heat with the refrigerant condensation passage in the condenser, or it can achieve indirect heat exchange through a heat exchanger.
[0061] The compression refrigeration system 2 can mainly include a heating channel 2-6, and also needs to include a compressor 2-1, a throttling device 2-3, etc. The heating channel 2-6 is used to absorb heat from the fluid compressed by the compressor 2-1, thereby raising the internal temperature of the fluid. The heating channel 2-6 can be located outside the casing of the compressor 2-1. The compressed refrigerant will heat up and transfer heat to the casing of the compressor 2-1. Alternatively, the heating channel 2-6 can obtain heat from the condenser of the compression refrigeration system 2. The high-temperature compressed refrigerant will enter the condenser, and the heating channel 2-6 can directly exchange heat with the refrigerant condensation channel in the condenser, or it can achieve indirect heat exchange through a heat exchanger.
[0062] Correspondingly, the outlet of the heating channel 2-6 can supply supplementary heating fluid to the corresponding heat source inlet 1-1 through the first control valve 11. As mentioned above, the heating channel 2-6 can be connected in parallel with the heat source supply inlets 9, or it can be connected in series.
[0063] In use, the operating power of the compression refrigeration system 2 can be controlled according to the heat flux at the heat source supply port 9, so that the heat flux at the outlet of the heated channel 2-6 can meet the requirements after supplementing the heat flux. In the above setting, compared with the combination of the adsorption refrigeration system of the single adsorption refrigeration module 1 and the compression refrigeration system 2, it can avoid excessive heat flux supplemented by the compression refrigeration system 2, which would lead to excessive total cooling capacity.
[0064] Specifically, it is preferable that the heat source supply port 9 and the heating channel 2-6 are connected in series. If a heat source supply channel 4 is provided, each of the heat source inlets 1-1 is connected to the heat source supply channel 4. For example, multiple switching valves can be connected to each heat source inlet 1-1 respectively. In this case, the heating channel 2-6 is connected in series between the heat source supply port 9 and the heat source supply channel 4.
[0065] In some embodiments, the inlet of the heated channel 2-6 can be connected to the heat source supply port 9 to receive all the heat source fluid from the heat source supply port 9. Then, a controller is set up so that when the heat source fluid flow rate is stable but the temperature fluctuates, the compression power of the compression refrigeration system 2 can be controlled based on the acquired outlet temperature of the heated channel 2-6 to adjust the heating power of the heated channel 2-6, thereby ensuring that the outlet temperature of the heated channel 2-6 meets the requirements. Furthermore, the temperature of the heat source supply port 9 is acquired in real time. If the temperature is significantly low, it is necessary to shut down part of the adsorption refrigeration module 1. In this case, the driving power of the drive pump can be reduced accordingly to decrease the flow rate and thus reduce the flow rate.
[0066] In some embodiments, a chilled fluid supply port 14 may be further provided, which can be directly or indirectly connected to the outlet of the chilled fluid channel 1-7. That is, the chilled fluid channel 1-7 is used to supply fluid to the chilled fluid supply port 14, so that after the chilled fluid in the chilled fluid channel 1-7 has released heat and cooled down, it can be supplied to the chilled fluid supply port 14, thereby transferring heat away. In use, the low-temperature fluid in the chilled fluid supply port 14 can flow directly into the object being cooled for direct heat exchange, or it can indirectly absorb heat from the object being cooled through a heat exchanger. The chilled fluid after heat absorption can be directly discharged, or it can flow back into the chilled fluid channel 1-7 to adsorb working fluid and release heat again in the bed evaporator 1-3.
[0067] The compression refrigeration system 2 also includes a heat release channel 2-8, which is used to release heat to the throttled refrigerant. The temperature of the throttled refrigerant will decrease, thus enabling it to absorb heat. The heat release channel 2-8 can directly exchange heat with the channel through which the throttled refrigerant flows, or it can indirectly release heat to the throttled refrigerant using a heat exchanger. Specifically, the heat release channel 2-8 can be located at the evaporator of the compression refrigeration system 2.
[0068] The outlet of heat dissipation channel 2-8 is connected to the refrigerant supply port 14 to supply low-temperature fluid. After entering the heat exchange channel 1-4, the fluid transfers heat to the throttled refrigerant, and after its temperature decreases, it is supplied to the refrigerant supply port 14 to absorb heat from the object being cooled. It should be noted that the fluid at the inlet of heat dissipation channel 2-8 can come directly from the outside or from the object being cooled, or it can come from the refrigerant channel 1-7.
[0069] In some embodiments, the compression refrigeration system 2 may specifically include a compressor 2-1, a condenser heat exchanger 2-2, a throttling device 2-3, and an evaporator heat exchanger 2-4. The condenser heat exchanger 2-2 includes a condensing-side refrigerant passage 2-5 and a heated passage 2-6 that exchange heat with each other, while the evaporator heat exchanger 2-4 includes an evaporator-side refrigerant passage 2-7 and a heat-dissipating passage 2-8 that exchange heat with each other. The compressor 2-1, the condensing-side refrigerant passage 2-5, the throttling device 2-3, and the evaporator-side refrigerant passage 2-7 are sequentially and cyclically connected.
[0070] When in use, the refrigerant, after being compressed by compressor 2-1, forms a hot fluid. This hot fluid exchanges heat with the heated channel 2-6 in the condensing refrigerant channel 2-5, thus raising the temperature of the fluid in the heated channel 2-6. Generally, the temperature of the compressed hot fluid needs to be higher than the set heating fluid temperature of the adsorbent in the adsorption bed 1-2 to ensure that the heated channel 2-6 is effectively heated to meet the requirements of the adsorption bed 1-2. After releasing heat, the refrigerant in the refrigerant channel cools down. The cooled fluid is then throttled by the throttling device 2-3 to form a low-temperature fluid. This low-temperature fluid enters the evaporating refrigerant channel 2-7, where it absorbs heat from the heat release channel 2-8 to achieve a temperature increase. After flowing out of the evaporating refrigerant channel 2-7, the refrigerant can re-enter the compressor 2-1, where it is compressed and supplied to the condensing refrigerant channel 2-5. This cycle repeats continuously, and during the cycle, the refrigerant may undergo a gas-liquid phase transition. It should be noted that if the refrigerant temperature at the inlet of the throttling device 2-3 is too high, a portion of the refrigerant can be discharged from the throttling outlet to cool the inlet refrigerant and meet the throttling requirements. From a temperature perspective, to better meet usage requirements, the inlet temperature of the condensing-side refrigerant channel 2-5, the outlet temperature of the condensing-side refrigerant channel 2-5, the inlet temperature of the heat exchange channel 1-4, and the inlet temperature of the heat receiving channel 2-6 can be decreased sequentially; while the inlet temperature of the evaporating-side refrigerant channel 2-7, the outlet temperature of the evaporating-side refrigerant channel 2-7, the temperature of the chilled fluid supply port 14, and the inlet temperature of the heat release channel 2-8 can be increased sequentially.
[0071] By using the above method, the number of heat exchange stages can be reduced, thereby improving heat transfer efficiency.
[0072] Furthermore, the heat release channel 2-8 can be connected in series between the refrigeration fluid channel 1-7 and the refrigeration fluid supply port 14, or the refrigeration fluid channel 1-7 and the heat release channel 2-8 can be connected in parallel.
[0073] In some embodiments, considering that the temperature of the heat source fluid may be insufficient, lower than the fluid temperature required by the adsorption bed 1-2, but higher than the temperature at the outlet of the heat exchange channel 1-4, and therefore still has heat available for utilization, an intermediate connecting channel and a first valve device may be included, wherein the intermediate connecting channel and the heated channel 2-6 are optionally connected to the heat source supply port 9 and the heat source supply channel 4 via the first valve device.
[0074] In some embodiments, when a portion of the adsorption refrigeration module 1 is shut down, the corresponding cooling fluid and chilled fluid should also be stopped from being supplied. Based on this, a second control valve 12 and a third control valve 13 are preferably provided here. The first control valve 11, the second control valve 12 and the third control valve 13 can be configured as needed. They can all be multi-way valves, or the first control valve 11, the second control valve 12 and the third control valve 13 can form a reversing valve to control simultaneously.
[0075] In some embodiments, to facilitate control by the first control valve 11, a heat source discharge channel 3 and a heat source supply channel 4 may be provided. The first control valve 11 includes a plurality of first switching valve units 11-1. Each adsorption refrigeration module 1 includes a heat source outlet 1-16 for discharging the heat source fluid after heat release in the heat exchange channel 1-4. In each adsorption refrigeration module 1, the first switching valve unit 11-1 is provided between the heat source inlet 1-1 and the heat source supply channel 4 and / or between the heat source outlet 1-16 and the heat source discharge channel 3. As shown in the attached figures, each heat source inlet 1-1 is connected to the heat source supply channel 4 through the first switching valve unit 11-1.
[0076] In some embodiments, to facilitate control by the second control valve 12, a refrigerant discharge channel 5 and a refrigerant supply channel 6 may be provided. The second control valve 12 includes multiple second switching valve units 12-1. In each of the adsorption refrigeration modules 1, the second switching valve unit 12-1 is provided between the refrigerant supply channel 6 and the inlet of the refrigerant channel 1-7, and / or between the outlet of the refrigerant channel 1-7 and the refrigerant discharge channel 5. As shown in the accompanying drawings, the inlet of each refrigerant channel 1-7 is connected to the refrigerant supply channel 6 via the second switching valve unit 12-1.
[0077] In some embodiments, to facilitate control by the third control valve 13, a cooling fluid discharge channel 7 and a cooling fluid supply channel 8 may be provided. The adsorption refrigeration module 1 is provided with a cooling fluid inlet 1-14 and a cooling fluid outlet 1-15. The cooling fluid inlet 1-14 can introduce cooling fluid for absorbing heat from the adsorption bed 1-2 and the bed condenser 1-18, and the cooling fluid outlet 1-15 can discharge the cooled fluid after heat absorption. The third control valve 13 includes multiple third switching valve units 13-1. In each adsorption refrigeration module 1, the third switching valve unit 13-1 is provided between the cooling fluid inlet 1-14 and the inlet of the cooling fluid supply channel 8 and / or between the cooling fluid outlet 1-15 and the cooling fluid discharge channel 7. As shown in the figures, each cooling fluid inlet 1-14 is connected to the cooling fluid supply channel 8 through the third switching valve unit 13-1.
[0078] It should be noted that the cooling fluid for the adsorption bed 1-2 and the cooling fluid for the condenser can come from the same cooling fluid supply channel 8 or from different cooling fluid channels. When they come from the same cooling fluid supply channel 8, the cooling fluid for the adsorption bed 1-2 and the cooling fluid for the condenser can come from the cooling fluid supply channels 8 separately, or they can be connected in series.
[0079] As shown in the attached diagram, when all adsorption-cooling modules 1 need to be opened, the controller can be used to open each of the first switching valve units 11-1, the second switching valve units 12-1, and the third switching valve units 13-1. If only three adsorption-cooling modules 1 need to be opened, then the first switching valve units 11-1, the second switching valve units 12-1, and the third switching valve units 13-1 corresponding to any three adsorption-cooling modules 1 can be opened, while the first switching valve units 11-1, the second switching valve units 12-1, and the third switching valve units 13-1 corresponding to the other adsorption-cooling module 1 can be closed. If only two adsorption-cooling modules 1 need to be opened, then the first switching valve units 11-1, the second switching valve units 12-1, and the third switching valve units 13-1 corresponding to any two adsorption-cooling modules 1 can be opened, while the first switching valve units 11-1, the second switching valve units 12-1, and the third switching valve units 13-1 corresponding to the other two adsorption-cooling modules 1 can be closed. If only one adsorption refrigeration module 1 needs to be turned on, then the first switching valve unit 11-1, the second switching valve unit 12-1, and the third switching valve unit 13-1 corresponding to any one adsorption refrigeration module 1 will be turned on, while the first switching valve unit 11-1, the second switching valve unit 12-1, and the third switching valve unit 13-1 corresponding to the other three adsorption refrigeration modules 1 will be turned off.
[0080] In some embodiments, a typical adsorption refrigeration system is provided with a bed condenser 1-18. Generally, the bed condenser 1-18 and the bed evaporator 1-3 are provided separately, but they can also be provided together, such as by using a heat exchanger to be used alternately as the bed condenser 1-18 and the bed evaporator 1-3.
[0081] In each refrigeration module, the evaporation chamber 1-6 of the bed evaporator 1-3 is optionally connected to the adsorption chamber 1-5 of different adsorption beds 1-2 through the first valve group 1-8. The bed evaporator 1-3 is also provided with a cryogenic fluid channel 1-7 for heat exchange with the liquid adsorbent in the evaporation chamber 1-6. The cryogenic fluid channel 1-7 is used to cool the object being cooled. Generally, the cryogenic fluid channel 1-7 and the channel in the object being cooled form a circulating flow so that after absorbing heat in the object being cooled, it flows back to the cryogenic fluid channel 1-7 and then releases heat in the bed evaporator 1-3, so that the liquid adsorbent in the evaporation chamber 1-6 evaporates to carry away the heat. The heat release channel 2-8 can be set up in series or in parallel with the cryogenic fluid channel 1-7. When the adsorption bed 1-2 is in the adsorption stage, the adsorption chamber 1-5 of the adsorption bed 1-2 is connected to the evaporation chamber 1-6, so that the gaseous adsorbent in the evaporation chamber 1-6 can enter the adsorption chamber 1-5 and be adsorbed by the adsorbent. The first valve group 1-8 can be a multi-way valve or a valve group formed by a combination of multiple switching valves. As shown in the attached figure, the outlet of the evaporation chamber 1-6 is connected to the adsorption chamber 1-5 of each adsorption bed 1-2 through multiple switching valves. It should be noted that there can be one bed evaporator 1-3 or multiple bed evaporators 1-3.
[0082] In each refrigeration module, the condensing chamber of the bed condenser 1-18 is optionally connected to the adsorption chamber 1-5 of different adsorption beds 1-2 through the second valve group 1-9. The bed condenser 1-18 also has a cooling fluid channel for heat exchange with the gaseous adsorbent in the condensing chamber. This cooling fluid channel primarily introduces external cooling water to absorb heat from the gaseous adsorbent in the condensing chamber, allowing it to condense into a liquid adsorbent, thus enabling continuous intake of gaseous adsorbent from the corresponding adsorption chamber 1-5. When the adsorption bed 1-2 is in the desorption stage, its adsorption chamber 1-5 is connected to the condensing chamber. The second valve group 1-9 can be a multi-way valve or a valve group formed by combining multiple switching valves. As shown in the attached diagram, the inlet of the condensing chamber is connected to the adsorption chamber 1-5 of each adsorption bed 1-2 through multiple switching valves. It should be noted that there can be one bed condenser 1-18 or multiple bed condensers 1-18.
[0083] In some embodiments, the first end of each heat exchange channel 1-4 may be optionally connected to the heat source inlet 1-1 via the first multi-way valve 1-10, and the second end of each heat exchange channel 1-4 may be optionally connected to the heat source outlet 1-16 via the second multi-way valve 1-11, so that heating fluid may be optionally introduced into each heat exchange channel 1-4.
[0084] Each heat exchange channel 1-4 has its first end connected to a respective outlet of a first multi-way valve 1-10, and its inlet connected to a heat source inlet 1-1. The inlet of the first multi-way valve 1-10 can optionally be connected to any one of its outlets. Similarly, each heat exchange channel 1-4 has its second end connected to a respective inlet of a second multi-way valve 1-11, and its outlet connected to a heat source outlet 1-16. The outlet of the second multi-way valve 1-11 can optionally be connected to any one of its inlets. The first multi-way valve 1-10 and the second multi-way valve 1-11 can be combined to form a reversing valve structure or can be separate multi-way valve structures.
[0085] In some embodiments, the first end of each heat exchange channel 1-4 may be optionally connected to the cooling fluid inlet 1-14 via a third multi-way valve 1-12, and the second end of each heat exchange channel 1-4 may be optionally connected to the cooling fluid outlet 1-15 via a fourth multi-way valve 1-13, so that cooling fluid can be optionally introduced. In this case, the cooling fluid used to cool the adsorbent in the adsorption stage and the heating fluid used to heat the adsorbent in the desorption stage can share the heat exchange channel 1-4, so that heating fluid (heat source fluid) and cooling fluid alternately flow into the heat exchange channel 1-4.
[0086] Specifically, preferably, the first end of each heat exchange channel 1-4 is connected to each outlet of the third multi-way valve 1-12, and the inlet of the third multi-way valve 1-12 is connected to the cooling fluid inlet 1-14. The inlet of the third multi-way valve 1-12 can optionally be connected to any one of the outlets. The second end of each heat exchange channel 1-4 is connected to each inlet of the fourth multi-way valve 1-13, and the outlet of the fourth multi-way valve 1-13 is connected to the cooling fluid outlet 1-15. The outlet of the fourth multi-way valve 1-13 can optionally be connected to any one of the inlets.
[0087] In some embodiments, the first control valve 11, the second control valve 12 and the third control valve 13, as well as the first valve group 1-8 and the second valve group 1-9, and the first multi-way valve 1-10, the second multi-way valve 1-11, the third multi-way valve 1-12 and the fourth multi-way valve 1-13 can all be electrically controlled valves to facilitate control.
[0088] In some embodiments, unless otherwise stated or contradicted, the adsorption refrigeration system comprises an adsorption working fluid circulation system consisting of adsorption beds 1-2, a condenser, and an evaporator. Specifically, it may constitute a multi-stage circulation system, a return circulation system, a thermal wave circulation system, or other circulation systems.
