Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As can be seen from the foregoing, the prior art generally employs a heating device to remove frost condensed on the refrigeration module in a heating manner. Therefore, the temperature of the area is increased and the temperature fluctuation of the room is large in the heating defrosting process and the cooling process after defrosting, and abnormal sound is generated due to expansion with heat and contraction with cold when the refrigerating module works again. Moreover, such abnormal changes in zone temperature also cause energy losses. In order to solve the technical problem, the following technical solutions are provided in the present application.

As shown in fig. 1, the present embodiment provides a water-gas separation device, including: an adsorption bed 1, wherein an inner cavity of the adsorption bed 1 is filled with an adsorbent 21;

a heating assembly 2, wherein the heating assembly 2 can exchange heat with the adsorption bed 1; the heat exchange can be realized by adopting a connection or non-connection assembly mode;

and the water storage cavity of the water storage device 3 is communicated with the inner cavity of the adsorption bed 1.

As shown in fig. 1 in combination with fig. 2 and 3, when the water-gas separation device is used to defrost the refrigeration device 86, the water-gas separation device may be installed in front of the refrigeration device 86. It should be noted that, in the process of cooling the refrigeration apparatus, the refrigeration apparatus 86 for cooling is located in the evaporator cavity 81 of the refrigeration apparatus, a pair of air outlet 83 and air return 84 capable of forming a circular flow between the evaporator cavity 81 and the refrigeration compartment 82 of the refrigeration apparatus is provided between the evaporator cavity 81 and the refrigeration compartment 82 (i.e. the air can flow along the direction from the air outlet 83, the refrigeration compartment 82, and the air return 84 to the evaporator cavity 81, and continuously enter the refrigeration compartment 82 from the air outlet 83 in a circular manner), the refrigeration apparatus utilizes the refrigeration apparatus 86 to cool the high-temperature high-humidity air and then change the air into low-temperature low-humidity air (where the air becomes low-humidity and is accompanied by frosting of the refrigeration apparatus 86), the air enters the refrigeration compartment 82 from the air outlet 83 to cool the environment in the refrigeration compartment 82, in this process, the temperature and the humidity of the low-temperature low-humidity air can rise again after heat exchange with the inner cavity of the refrigeration compartment 82, the air is changed back to the high-temperature and high-humidity air, and continuously circulates back to the evaporator cavity 81 along the air return opening 84, and the high-temperature and high-humidity air passes through the air return opening again and is cooled by the refrigerating device 86, so that the temperature and the humidity of the air are reduced (along with the frosting of the refrigerating device 86), and the air is changed into the low-temperature and low-humidity air again. An air circulation path 85 through which air circulates is formed along the air circulation direction of the evaporator chamber 81, the air outlet 83, the refrigerating compartment 82, and the air return opening 84, and this process is continuously circulated in the air circulation path 85. At this time, the moisture separator is installed in a position before the cooling device 86, i.e., in the return air circulation direction of the air circulation path 85, between the return air inlet 84 and the cooling device 86.

After the water-vapor separation device is assembled in place, when the high-temperature and high-humidity air flowing through the refrigerating chamber 82 is subjected to heat exchange and circularly flows back to the evaporator cavity 81 from the air return inlet 84, the high-temperature and high-humidity air firstly passes through the water-vapor separation device, the water-vapor separation device is provided with the adsorption bed 1, the adsorbent 21 in the inner cavity of the adsorption bed 1 can adsorb moisture in the high-temperature and high-humidity air, so that the high-temperature and high-humidity air is changed into medium-temperature and low-humidity air (the adsorption process is accompanied with the generation of cold energy), when the medium-temperature and low-humidity air flows to the refrigerating device 86 again, because the humidity is greatly reduced or even removed, the frosting of the refrigerating device 86 can be greatly reduced or completely avoided, and then the refrigerating device 86 is utilized to continuously cool the medium-temperature and low-humidity air, so that the medium-temperature and low-humidity air is changed into low-temperature and low-humidity air and then continuously enters the refrigerating chamber 82.

The adsorbent 21 has low-temperature adsorption and high-temperature desorption effects, and for example, MOF material, zeolite, silica gel, or the like can be used as the adsorbent 21. When the adsorbent 21 is used for a certain period of time, the adsorbent 21 absorbs a large amount of water, so that the adsorption performance of the adsorbent 21 is reduced, at this time, the heating assembly 2 can be used for heating the adsorption bed 1, so that the adsorbent 21 is heated, the water absorbed in the adsorbent 21 is decomposed and adsorbed, and the water flows into the water storage cavity of the water storage device 3 for storage, so that the adsorbent 21 has good adsorption performance again, the service life of the adsorbent 21 is prolonged, and the process can be performed when air is not circulated in the refrigeration chamber 82.

Wherein the water in the reservoir chamber may be periodically cleaned, for example by providing a drain opening in the reservoir 3, or by evaporative removal, or by re-use in other arrangements. The technical personnel in the field can be reasonably arranged according to the specific structure of the device, and the detailed description is omitted.

In summary, in the process of the internal circulation of the air circulation path 85, before passing through the refrigeration device 86, moisture in the air is adsorbed by the moisture separation device, and a certain amount of cold is generated through the adsorption process, so that the high-temperature and high-humidity air is changed into medium-temperature and low-humidity air and then flows to the refrigeration device 86 to be cooled, and therefore, the refrigeration device 86 can be effectively prevented from frosting in the whole refrigeration process, the ambient temperature around the refrigeration device 86 is not greatly changed, the refrigeration device 86 works in a temperature stable environment, and abnormal noise is avoided; and the long service life is ensured by the characteristics of low-temperature adsorption and high-temperature desorption of the adsorbent 21.

Meanwhile, because the frosting amount of the refrigerating device 86 is greatly reduced, even frosting is avoided, the heat exchange thermal resistance is small, the heat exchange effect is improved, and the energy consumption is effectively reduced; the defrosting period is prolonged, the defrosting time is shortened, the power consumption of temperature rise loss in the defrosting process is low, and the energy consumption is further reduced; and the temperature of the refrigerating chamber 82 can be prevented from being fluctuated severely due to defrosting, and the food storage is facilitated.

In addition, because the adsorption process is accompanied by the generation of cold energy, the temperature of the high-temperature and high-humidity air is slightly reduced before flowing through the refrigerating device 86, and the high-temperature and high-humidity air is changed into medium-temperature and high-humidity air, so that a certain cooling effect is formed, the energy consumption of the refrigerating device 86 can be reduced, and the energy is saved.

Further, as shown in fig. 4 and 5, the water-gas separation device further includes: a heat dissipation assembly 4, the heat dissipation assembly 4 being disposed in a communication passage between the adsorption bed 1 and the water reservoir 3.

The arrangement of the heat dissipation component 4 also accelerates the storage process of the moisture after the adsorption bed 1 is desorbed at high temperature, thereby improving the working efficiency. As is clear from the above, since the adsorbent 21 has the characteristics of low-temperature adsorption and high-temperature desorption, when the heating module 2 heats the adsorbent 21 to cause high-temperature desorption, water vapor is generated. In general, this high temperature desorption process can be performed without circulating air in the refrigeration compartment 82, and water vapor is condensed into liquid water by sublimation and flows into the reservoir 3 to be stored. The desublimation process is slow, so that the heat dissipation of the water vapor can be accelerated through the heat dissipation component 4, the desublimation process is accelerated, and the speed of the desorption process is increased. Wherein the heat sink assembly 4 is located in a communication path between the adsorption bed 1 and the water reservoir 3, and can dissipate heat from the water vapor during the process of flowing to the water reservoir 3, so that the water vapor is condensed into liquid. The heat dissipation assembly 4 can adopt a heat dissipation structure with a heat dissipation effect, and can also directly adopt a refrigeration structure with a refrigeration effect to actively cool and dissipate heat. Depending on the characteristics of the specific structure employed, it may be disposed inside the communication path or outside the communication path. For example, the heat dissipating structure having a heat dissipating function may be disposed outside the communication passage, and the cooling structure having a cooling function may be disposed inside the communication passage.

Preferably, with continued reference to fig. 4 and 5, the water gas separation device further comprises: one end of the water storage pipe 31 is communicated with the water storage cavity of the water storage device 3, and the other end of the water storage pipe 31 is communicated with the inner cavity of the adsorption bed 1; the heat sink assembly 4 and the water storage pipe 31 can exchange heat.

The pipeline structure of the water storage pipe 31 can be adopted between the inner cavity of the adsorption bed 1 and the water storage cavity of the water storage device 3 to guide the desorbed water vapor, and the heat dissipation component 4 is arranged on the water storage pipe 31 to dissipate the heat of the water vapor in the process that the water vapor flows through the water storage pipe 31, so that the water vapor is rapidly condensed into liquid water. The water storage pipe 31 has a large surface area, so that the heat dissipation effect is improved, and the desublimation process is accelerated.

Preferably, the heat dissipation assembly 4 includes a plurality of heat dissipation fins; a plurality of the radiating fins are uniformly distributed on the outer wall of the water storage pipe 31. Therefore, the surface area of the water storage pipe 31 can be fully utilized by utilizing the plurality of radiating fins which are uniformly distributed, so that the radiating effect is improved, and the desublimation process is accelerated.

Besides the heat dissipation fins, the heat dissipation assembly 4 may also adopt other structural forms, such as a material with a heat dissipation effect, or a fan to achieve heat dissipation, or even a device with a refrigeration effect to achieve heat dissipation directly. Therefore, those skilled in the art can select the specific method according to the actual situation, and the detailed description is omitted here.

Further, as shown in fig. 6, the water-gas separation device further includes: a moisture circulation passage 5, one end of the moisture circulation passage 5 being communicated with the water storage chamber of the water reservoir 3, the other end of the moisture circulation passage 5 being open;

and the drainage component is arranged in a manner of draining the water in the water storage cavity to the open end of the water storage cavity along the moisture circulating channel 5. The drainage member may be installed inside the water reservoir 3 or the moisture circulation passage 5, or outside and near to an opening of either one of them, as long as the drainage of moisture can be achieved.

Also associated with the reservoir 3 is a moisture circulation channel 5, which moisture circulation channel 5 is capable of reusing moisture in the reservoir 3. The moisture circulation passage 5 may have a solid pipe structure, or may define a passage structure in the refrigerating apparatus. The open end of the moisture circulation passage 5 may face the outlet opening 83 of the refrigeration device. Therefore, when a water source needs to be utilized in the refrigerating compartment 82, for example, humidification or ice making is needed, the moisture in the water reservoir 3 can be guided to the air outlet 83 and enter the refrigerating compartment 82 from the air outlet 83, and the humidification or ice making can be realized. During the diversion of the moisture, this can be achieved by the diversion assembly, so that the moisture can be actively guided into the refrigeration compartment 82 in the event of a water source being required.

Therefore, through the cooperation of the water storage device 3 and the moisture circulation channel 5, the moisture in the water storage device 3 can be reasonably secondarily utilized, and the processing work of the moisture stored in the water storage device 3 can be simplified. After the water in the water storage device 3 is reused, the water storage cavity in the water storage device 3 has the water storage capacity again, and the service life of the water storage device 3 is prolonged.

Preferably, the drainage component is a heater; the heater and the moisture circulation channel 5 can exchange heat so as to heat and evaporate water in the water storage cavity and then guide the water to one open end of the moisture circulation channel 5;

or the drainage component is a water pump; the water pump is disposed in the water reservoir 3 or the moisture circulation passage 5 to be able to guide the water in the water storage chamber to an open end thereof along the moisture circulation passage 5.

When the heater is adopted as the drainage assembly, the heater can heat the water storage device 3 or the moisture circulation channel 5, so that the moisture in the water storage cavity is heated and evaporated to form water vapor. The water vapor can flow along the moisture circulation passage 5 to the open end thereof, and enter the refrigerating compartment 82 from the open end thereof along the air outlet 83, thereby performing the humidifying operation on the refrigerating compartment 82.

When the water pump is adopted as the drainage assembly, the water pump can directly form power diversion on the moisture in the water storage cavity, so that the moisture flows to the open end of the moisture circulation channel 5 under the power driving of the water pump, and enters the refrigerating chamber 82 from the open end of the moisture circulation channel along the air outlet 83, and the ice making operation of the refrigerating chamber 82 is realized.

Besides the heater and the water pump, the diversion assembly may also adopt other devices capable of guiding the moisture along the moisture circulation channel 5 to the open end thereof, such as a water absorption structure, and the like, which will not be described in detail herein.

Further, as shown in fig. 7, the water-gas separation device further includes: a drain pipe 32, wherein a pipeline switch 33 is arranged on the drain pipe 32;

one end of the drain pipe 32 is communicated with the water storage chamber of the water reservoir 3, and the other end of the drain pipe 32 is opened.

The water storage tank 3 is matched with a drain pipe 32 and a pipeline switch 33, so that the water storage capacity of the water storage tank 3 can be flexibly utilized. When the cooling compartment 82 is temporarily without water demand but the water storage capacity in the reservoir 3 is excessive, it is impossible to guide water into the cooling compartment 82 through the moisture circulation passage 5 to allow the reservoir 3 to regain the water storage capacity. Therefore, the water discharge pipe 32 can be opened by the pipe switch 33 at this time, so that the water in the reservoir 3 is discharged through the water discharge pipe 32, thereby allowing the reservoir 3 to regain the water storage capacity.

The open end of the drain pipe 32 may face or be connected to a position capable of containing or treating the outflow water, and the position may be exposed outside the refrigeration equipment, or connected to another water storage equipment, or be secondarily utilized by another device, which is not described herein again.

Further, as shown in fig. 8, the water-gas separation device further includes: the water level sensor 34 is arranged in the water storage cavity and used for detecting the water level value in the water storage cavity; the pipeline switch 33 is in data connection with the water level sensor 34 and is used for acquiring the water level value; and when the water level value exceeds the preset range, the pipeline switch 33 opens the drain pipe 32.

The water level sensor 34 is used in cooperation with a water level sensor to automatically perform the water treatment operation in the water reservoir 3 under a preset program. If there is no water demand in the refrigerating compartment 82, more water is accumulated in the water storage cavity, and at this time, the water level sensor 34 can detect the water level value in the water storage cavity, and when the water level value is higher, it means that more water is stored in the water storage cavity, so that the pipeline switch 33 automatically opens the water discharge pipe 32 when the water level value reaches a higher range, and the water is discharged. When the water level value is reduced and is not within the preset range, the pipeline switch 33 closes the drain pipe 32 again, so that the water storage device 3 has the water storage capacity again. The control process can be realized by a matched controller or a data processor, and can be prepared by persons skilled in the art, so that the detailed description is omitted.

For example, the preset range of the water level value can be set to be 0% -80% of the total water storage amount of the water storage cavity, that is, the water level value is 0% -80% of the total water storage amount of the water storage cavity, which belongs to an acceptable water storage state, so that a certain amount of available water in the water storage cavity can be ensured, but the water level value does not occupy too much space of the water storage cavity, and the water storage capacity of the water storage cavity is worried. Therefore, in this setting, the pipe switch 33 can open the drain pipe 32 to drain once the water level sensor 34 detects that the water level value exceeds the range of 0% -80%, i.e., exceeds 80%, and the pipe switch 33 can close the drain pipe 32 when the water level value is restored to any water level value within the range of 0% -80%.

It should be noted that, a person skilled in the art may also set a range of water level values for closing the drain pipe 32 by the pipeline switch 33, so as to control the closing of the drain pipe 32 more flexibly, and details thereof are omitted here.

Further, the heating component 2 is a heating wire; the heating wire is buried inside the adsorbent 21.

With continued reference to fig. 1, in order to heat the adsorbent 21 more sufficiently and efficiently by the heating unit 2, and to obtain a better high-temperature desorption effect of the adsorbent 21, the heating unit 2 is configured by embedding a heating wire in the adsorbent 21. Since the heater wire has a long structural feature, when it is embedded in the adsorbent 21, it can be uniformly contacted with a plurality of places inside the adsorbent 21, and the adsorbent 21 is uniformly and sufficiently heated inside the adsorbent 21. This makes it possible to desorb the adsorbent 21 more sufficiently and more quickly.

Besides the heating wire, the heating assembly 2 may also adopt other heating structures, such as a heating rod, a heating sheet, and the like, which are not described herein again.

Further, the water-gas separation device further comprises: and the cooling component is close to or connected with the adsorption bed 1 and is used for cooling the adsorbent 21.

The adsorbent 21 such as MOF material, zeolite, silica gel, etc. has not only the effect of low-temperature adsorption but also the effect of its own temperature on the adsorption performance. For example, the MOF material absorbs water at normal temperature, but in order to ensure good water absorption effect, the working temperature of the MOF material can be set between 15 ° and 25 °. For example, the MOF material may have a 40% increase in water absorption compared to normal temperature at 15 °.

Since the refrigeration apparatus is in the normal temperature, the temperature of the adsorbent 21 is also in the normal temperature range in the normal case. Therefore, the temperature reducing component (not shown) can be used to reduce the temperature of the adsorbent 21 and adjust the temperature of the adsorbent 21, so that the temperature of the adsorbent 21 is reduced to a reasonable temperature range, and a good adsorption effect is obtained. Wherein, the cooling subassembly can adopt fan, cryogenic device etc. and no longer repeated here.

Further, the water-gas separation device further comprises: the temperature sensor 7 is connected with the adsorption bed 1, and is used for detecting the temperature value of the adsorbent 21;

the cooling assembly is in data connection with the temperature sensor 7 and is used for acquiring the temperature value; and when the temperature value is within the preset range, the temperature reduction component stops reducing the temperature of the adsorbent 21.

Since the temperature reduction assembly requires continuous temperature reduction of the adsorbent 21, the adsorbent 21 is at a lower temperature level, for example, the working temperature of the MOF material is maintained between 15 ° and 25 °. Therefore, the temperature of the adsorbent 21 can be automatically controlled by the cooling component under the preset program by matching with the temperature sensor 7.

After the temperature sensor 7 is connected with the adsorption bed 1, the temperature value of the adsorbent 21 can be detected by using the temperature sensor 7, when the temperature value is within a preset range, namely the temperature of the adsorbent 21 can make the adsorbent 21 obtain a good adsorption effect, the temperature of the adsorbent 21 does not need to be adjusted by the outside, and the cooling component can be closed at this time to stop cooling the adsorbent 21. Simultaneously, temperature sensor 7 still can carry out continuous control to adsorbent 21's temperature, and when adsorbent 21's temperature exceeded and predetermine the scope, also adsorbent 21 was in the relatively poor temperature range of adsorption effect promptly, and the subassembly that cools down still can continue for adsorbent 21 cooling this moment to automatic control has been realized. The control process can be realized by a controller or a data processor, and can be configured by those skilled in the art, which is not described herein.

Therefore, the control process can reasonably cool the adsorbent 21 by the cooling assembly when needed, so that the energy consumption of the cooling assembly is reduced, and the temperature of the adsorbent 21 can be accurately controlled. For different adsorbents 21, the preset range can also be set according to the characteristics of the specific adsorbent 21, so that various adsorbents 21 can keep a good adsorption effect within a reasonable temperature range.

The invention also provides refrigeration equipment comprising the water-gas separation device. Since the specific structure, functional principle and technical effect of the water-gas separation device are described in detail in the foregoing, they are not described herein again. Therefore, reference can be made to the above description for any technical contents related to the water-gas separation device.

The invention also provides refrigeration equipment, which comprises the water-gas separation device; also comprises a refrigeration box body 8;

an evaporator cavity 81 and at least one refrigerating compartment 82 are arranged in the refrigerating box body 8 at intervals, at least one pair of air outlet 83 and air return opening 84 are arranged between each refrigerating compartment 82 and the evaporator cavity 81, and an air circulation passage 85 is defined along the air circulation direction of the evaporator cavity 81, the air outlet 83, the refrigerating compartment 82 and the air return opening 84;

a refrigerating device 86, a first flow guide assembly 87 and the water-gas separation device are arranged in the evaporator cavity 81; the water-gas separation device is located between the air return opening 84 and the refrigerating device 86, and the first flow guide assembly 87 is located between the refrigerating device 86 and the air outlet 83.

As can be seen from the foregoing description of the water-gas separation device, after the water-gas separation device is disposed between the air return opening 84 and the refrigeration device 86, in the process of circulating in the air circulation path 85, the air passes through the water-gas separation device to absorb the moisture in the air before passing through the refrigeration device 86, and a certain amount of cold is generated through the absorption process, so that the high-temperature high-humidity air is changed into the medium-temperature low-humidity air and then flows to the refrigeration device 86 to be cooled, and therefore, the refrigeration device 86 can be effectively prevented from frosting in the whole refrigeration process, and the ambient temperature around the refrigeration device 86 does not change greatly, so that the refrigeration device 86 works in an environment with stable temperature, and abnormal sound is avoided; and the long service life is ensured by the characteristics of low-temperature adsorption and high-temperature desorption of the adsorbent 21. Meanwhile, because the frosting amount of the refrigerating device 86 is greatly reduced, even frosting is avoided, the heat exchange thermal resistance is small, the heat exchange effect is improved, and the energy consumption is effectively reduced; the defrosting period is prolonged, the defrosting time is shortened, the power consumption of temperature rise loss in the defrosting process is low, and the energy consumption is further reduced; and the temperature of the refrigerating chamber 82 can be prevented from being fluctuated severely due to defrosting, and the food storage is facilitated. In addition, because the adsorption process is accompanied by the generation of cold energy, the temperature of the high-temperature and high-humidity air is slightly reduced before the high-temperature and high-humidity air flows through the refrigerating device 86, and the high-temperature and high-humidity air is changed into medium-temperature and high-humidity air, so that the energy consumption of the refrigerating device 86 can be reduced, and the energy can be saved. For details, reference may be made to the above description, and details are not repeated herein.

The first flow guiding assembly 87 is used to guide the low-temperature air from the refrigerating device 86 to the refrigerating compartment 82, and the first flow guiding assembly 87 may adopt various mechanisms with flow guiding function, such as a fan. The refrigeration device 86 may employ a vapor compressor type refrigeration, a magnetic refrigeration, a semiconductor refrigeration, an adsorption type refrigeration, or the like. And will not be described in detail herein.

Further, as shown in fig. 9, the refrigeration apparatus further includes: a second flow guide assembly 6;

a temperature-reducing passage is defined between the refrigeration device 86 and the adsorbent bed 1, and the second flow-guiding assembly 6 is located near or in the temperature-reducing passage so as to be able to guide the low-temperature air portion from the refrigeration device 86 to the adsorbent 21.

As can be seen from the foregoing, the adsorbent 21, such as MOF material, zeolite, silica gel, etc., has the effect of low temperature adsorption, and the temperature itself has an influence on the performance of adsorption. At this time, in cooperation with the structural characteristics of the refrigeration apparatus, the low-temperature low-humidity cold air cooled by the refrigeration apparatus 86 may also be used to cool the adsorbent 21.

When the adsorbent 21 needs to be cooled by low-temperature low-humidity cold air, the second flow guide assembly 6 may be disposed at a position close to the cooling passage, or may be directly disposed inside the cooling passage, so that the second flow guide assembly 6 can be used to guide the low-temperature air from the refrigeration device 86 to the adsorbent 21.

As shown in fig. 9, the second flow guide assembly 6 may be assembled in a cooling passage defined between the refrigeration device 86 and the adsorbent bed 1, and since the air cooled by the refrigeration device 86 is low-temperature and low-humidity air, the second flow guide assembly 6 may guide the low-temperature and low-humidity air to the adsorbent 21 by using a flow guide effect thereof, so as to cool the adsorbent 21 by using a low temperature of the air. Meanwhile, since the air has low humidity, the water absorption effect of the adsorbent 21 is not lost. The second diversion component 6 may adopt various mechanisms with diversion function, such as a fan, which are not described herein again.

Further, as shown in fig. 10, the refrigeration apparatus further includes: the temperature sensor 7 is connected with the adsorption bed 1, and is used for detecting the temperature value of the adsorbent 21;

the second flow guide assembly 6 is in data connection with the temperature sensor 7 and is used for acquiring the temperature value; and when the temperature value is within the preset range, the second flow guide assembly 6 stops guiding the low-temperature air to the adsorption bed 1.

The control of the temperature of the adsorbent 21 by the second diversion assembly 6 can be automatically realized under a preset program by matching with the use of the temperature sensor 7.

Temperature sensor 7 with adsorption bed 1 is connected the back, utilizes temperature sensor 7 can detect adsorbent 21's temperature value, is in predetermineeing within the scope when the temperature value, and the temperature of adsorbent 21 also can make adsorbent 21 obtain good adsorption effect this moment, just does not need the adjustment of outside to adsorbent 21 temperature this moment, and second water conservancy diversion subassembly 6 can be closed this moment, stops to adsorption bed 1 water conservancy diversion low temperature air. Meanwhile, the temperature sensor 7 can continuously monitor the temperature of the adsorbent 21, and when the temperature of the adsorbent 21 exceeds a preset range, that is, the adsorbent 21 is in a temperature range with a poor adsorption effect, the second flow guide assembly 6 can continuously guide low-temperature air to the adsorption bed 1, so that automatic control is realized. The control process can be realized by a matched controller or a data processor, and can be prepared by persons skilled in the art, so that the detailed description is omitted.

Therefore, the control process can reasonably open the second flow guide assembly 6 when needed to guide the low-temperature air to the adsorption bed 1, so that the energy consumption of the second flow guide assembly 6 is reduced, the loss of the low-temperature low-humidity air from the refrigerating device 86 can be reduced, and all the low-temperature low-humidity air flows into the refrigerating compartment 82. At the same time, this control method can also precisely control the temperature of the adsorbent 21. For different adsorbents 21, the preset range can also be set according to the characteristics of the specific adsorbent 21, so that various adsorbents 21 can keep a good adsorption effect within a reasonable temperature range.

the moisture separator is arranged in front of the refrigeration device 86 along the return air circulation direction of the air circulation passage 85 in the refrigeration equipment, so that return air firstly passes through the adsorption bed 1, and the moisture in the air is absorbed by the adsorbent 21 and then flows to the refrigeration device 86; the heating module 2 is used for heating the adsorption bed 1, so that the water absorbed in the adsorbent 21 is decomposed and adsorbed.

Based on the assembly and use of the water-gas separation device, as can be seen by referring to the above description, after the water-gas separation device is arranged between the air return opening 84 and the refrigeration device 86, in the process of circulating in the air circulation passage 85, the air passes through the refrigeration device 86 before absorbing the moisture in the air, and generates a certain amount of cold energy through the absorption process, so that the high-temperature high-humidity air is changed into the medium-temperature low-humidity air and then flows to the refrigeration device 86 for cooling, therefore, the frosting of the refrigeration device 86 can be effectively avoided in the whole refrigeration process, the ambient temperature around the refrigeration device 86 does not change greatly, the refrigeration device 86 works in the environment with stable temperature, and the occurrence of abnormal noise is avoided; and the long service life is ensured by the characteristics of low-temperature adsorption and high-temperature desorption of the adsorbent 21. Meanwhile, because the frosting amount of the refrigerating device 86 is greatly reduced, even frosting is avoided, the heat exchange thermal resistance is small, the heat exchange effect is improved, and the energy consumption is effectively reduced; the defrosting period is prolonged, the defrosting time is shortened, the power consumption of temperature rise loss in the defrosting process is low, and the energy consumption is further reduced; and the temperature of the refrigerating chamber 82 can be prevented from being fluctuated severely due to defrosting, and the food storage is facilitated. In addition, because the adsorption process is accompanied by the generation of cold energy, the temperature of the high-temperature and high-humidity air is slightly reduced before flowing through the refrigerating device 86, and the high-temperature and high-humidity air is changed into medium-temperature and high-humidity air, so that the energy consumption of the refrigerating device 86 can be reduced, and the energy can be saved.
