[0037] In addition, the descriptions such as "first" and "second" in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0038] In combination with Figures 1-7As shown in the figure, an adsorption type cold air device includes a box body 1. An adsorption chamber is provided on the box body 1. A partition 2 is installed in the adsorption chamber. The partition 2 divides the adsorption chamber into a first adsorption bed 3 and a second adsorption bed 4. And the first adsorption bed 3 and the second adsorption bed 4 are connected through a mass return valve. The first adsorption bed 3 and the second adsorption bed 4 are also both connected to a condenser 5 and an evaporator 6. The condenser 5 and the evaporator 6 are also connected to each other. A cold water pipe 7 is also connected to the evaporator 6. The cold water pipe 7 is connected to a cold air mechanism 8. The condenser 5, the evaporator 6 and the cold air mechanism 8 are all installed on the box body 1 and are located at the bottom of the adsorption chamber;

[0039] It also includes a cooling tower 9 and a hot water tank 10. The cooling tower 9 is connected to the first adsorption bed 3, the second adsorption bed 4 and the condenser 5 through a cooling water pump. The hot water tank 10 is also connected to the first adsorption bed 3, the second adsorption bed 4 and the condenser 5 through a hot water pump. The hot water tank 10 is connected to an industrial waste heat pipeline or a solar water heater. Through the industrial waste heat pipeline or the solar water heater, the water in the hot water tank 10 can be heated. Through the hot water in the hot water tank 10, the first adsorption bed 3 or the second adsorption bed 4 can be heated, so that the refrigerant in the first adsorption bed 3 or the second adsorption bed 4 can be desorbed. The desorbed refrigerant can be condensed and evaporated in the condenser 5 and the evaporator 6, so as to achieve the refrigeration purpose. Through the cooling water in the cooling tower 9, the second adsorption bed 4 or the first adsorption bed 3 can be cooled down, so that the adsorbent in the second adsorption bed 4 or the first adsorption bed 3 can adsorb the refrigerant. Thus, continuous desorption and adsorption are carried out between the first adsorption bed 3 and the second adsorption bed 4 to achieve the function of cyclic refrigeration. Through the cold air mechanism 8, cold air can be directly blown out in the form of cold air to achieve the refrigeration and cooling effect. Compared with compression refrigeration, the structure is simple, the power consumption is saved, and the refrigeration effect is good;

[0040] In addition, various valves will be used during the operation of the adsorption type cold air device, such as solenoid valves, throttle valves, mass return valves, three-way valves, pressure valves, etc. Since the application of various valves belongs to the common knowledge of those skilled in the art in this technical field, it will not be elaborated here and is not marked in the figure either. Designers can add them according to the design requirements of the pipeline.

[0041] Combined with Figure 7 As shown in the figure, both the first adsorption bed 3 and the second adsorption bed 4 are provided with an adsorbent and a refrigerant. The absorbent used is silica gel, and the refrigerant used is water;

[0042] Temperature detectors 11 are also installed on both the first adsorption bed 3 and the second adsorption bed 4. The temperature detectors 11 are signal-connected to a controller. Through the temperature detectors 11, the water temperature in the first adsorption bed 3 and the second adsorption bed 4 can be detected.

[0043] Combined with Figure 7 As shown in the figure, the first adsorption bed 3 is respectively connected to the cooling tower 9 and the hot water tank 10 through a first three-way valve 12;

[0044] The second adsorption bed 4 is respectively connected to the cooling tower 9 and the hot water tank 10 through the second three-way valve 13;

[0045] Both the first three-way valve 12 and the second three-way valve 13 are signal-connected to the controller, and the opening and closing of the first three-way valve 12 and the second three-way valve 13 can be controlled through the controller.

[0046] When the temperature in the first adsorption bed 3 is relatively high, causing the cooling water temperature to be relatively high, the controller controls the first three-way valve 12 to directly feed the relatively high-temperature cooling water into the hot water tank 10. When the temperature in the second adsorption bed 4 is relatively low and the hot water flowing through the second adsorption bed 4 is cooled as its temperature decreases, the controller controls the second three-way valve 13 to directly feed the relatively low-temperature hot water into the cooling tower 9;

[0047] When the temperature in the second adsorption bed 4 is relatively high, causing the cooling water temperature to be relatively high, the controller controls the second three-way valve 13 to directly feed the relatively high-temperature cooling water into the hot water tank 10. When the temperature in the first adsorption bed 3 is relatively low and the hot water flowing through the first adsorption bed 3 is cooled as its temperature decreases, the controller controls the first three-way valve 12 to directly feed the relatively low-temperature hot water into the cooling tower 9, thereby realizing heat regeneration between the first adsorption bed 3 and the second adsorption bed 4.

[0048] Combined with Figures 1-4 As shown, the air-cooling mechanism 8 includes an air-cooling box 801. The air-cooling box 801 is arranged at the bottom of the box body 1. A number of air-cooling components 802 are arranged in a row inside the air-cooling box 801. All the a number of air-cooling components 802 are connected to the cold water pipe 7. An air outlet 803 is arranged at one end of the air-cooling box 801. A number of movable blades 804 are arranged in a row at the air outlet 803. All the a number of movable blades 804 are rotatably installed at the air outlet 803 through a support shaft 805 and are connected to an adjusting component 806. A blower 807 is installed at the other end of the air-cooling box 801. The blower 807 is arranged corresponding to the air outlet 803. Through the blower 807, the cold quantity of the air-cooling components 802 can be blown out from the air outlet 803 in the form of cold air. Through the adjusting component 806, the angles of the movable blades 804 can be uniformly adjusted so that the movable blades 804 can be opened or closed.

[0049] Combined with Figures 3-4 As shown, the adjacent air-cooling components 802 are arranged at equal intervals in the vertical direction and are staggered in the horizontal direction. By arranging the air-cooling components 802 at equal intervals in the vertical direction and staggering them in the horizontal direction, the air flow blown by the blower 807 can uniformly exchange heat with the air-cooling components 802, ensuring the effect of the blown cold air. At the same time, through the above structural design, the cold air temperature is more stable and the temperature fluctuation is reduced.

[0050] Combined with Figures 3-5As shown, the air cooling component 802 includes a tube body 8021, which is connected to the cold water pipe 7. A plurality of heat exchange fins 8022 are arranged along the axial direction on the tube body 8021. Each heat exchange fin 8022 is arranged in a diamond structure. By arranging the heat exchange fins 8022, the heat exchange area between the tube body 8021 and the air is increased, thereby improving the effect of generating cold air.

[0051] Combination Figures 3-6 As shown, the adjustment component 806 includes an adjustment rod 8061, which is movably connected to the movable blade 804. The end of the adjustment rod 8061 away from the movable blade 804 is inserted into the guide sleeve 8062 and connected to the limit block 8063. The limit block 8063 is slidably installed in the inner cavity of the guide sleeve 8062. The guide sleeve 8062 is installed in the air cooling box 801. A driving wheel 8064 is rotatably installed on the guide sleeve 8062, and the driving wheel 8064 is threadedly sleeved on the adjustment rod 8061. The driving wheel 8064 is driven by a belt. 8065 is connected to the driving motor 8066, and the adjusting rod 8061 can be limited by the limiting block 8063, so that the adjusting rod 8061 can only move axially but cannot rotate freely. The driving motor 8066 can drive the driving wheel 8064 to rotate, and the driving wheel 8064 drives the adjusting rod 8061 to move axially during the rotation. During the movement of the adjusting rod 8061, the movable blade 804 is pushed to rotate around the supporting shaft 805, thereby adjusting the angle of the movable blade 804, so that the movable blade 804 can be opened or closed;

[0052] In this embodiment, the limit block 8063 is designed as a rectangular structure, the inner cavity of the guide sleeve 8062 is adapted to the outer shape of the limit block 8063, and the limit block 8063 can slide up and down in the inner cavity of the guide sleeve 8062 along with the axial movement of the adjustment rod 8061.

[0053] Combination Figures 3-6 As shown, the adjustment rod 8061 includes a main rod body 80611, and one end of the main rod body 80611 close to the guide sleeve 8062 is provided with an external thread threadedly connected to the driving wheel 8064, and the external thread is threadedly connected to the internal thread provided on the driving wheel 8064.

During the rotation of the driving wheel 8064, the main rod body 80611 is driven to move axially, and during the axial movement of the main rod body 80611, the movable blade 804 is pushed to rotate around the support shaft 805, thereby realizing the adjustment of the angle of the movable blade 804, so that the movable blade 804 is opened or closed.

[0054] For ease of understanding, the working process of this embodiment is given below:

[0055] Combined Figures 1-7 As shown, the working principle of the adsorption - type cold air device for refrigeration is as follows:

[0056] 1: The first adsorption bed 3 desorbs, and the second adsorption bed 4 adsorbs:

[0057] The water in the hot water tank 10 is heated through the industrial waste heat pipeline or solar water heater. The hot water in the hot water tank 10 heats the first adsorption bed 3. The liquid refrigerant in the first adsorption bed 3 is heated and turns into steam and desorbs, and then enters the condenser 5. It releases heat and condenses into a liquid in the condenser 5. The liquid refrigerant flows into the evaporator 6 and changes from liquid to gas by absorbing heat in the evaporator 6. The refrigeration effect generated during heat absorption is transported to the air - cooling mechanism 8 through the cold water pipe 7 and is blown out by the air - cooling mechanism 8 in the form of cold air; while the cooling water flows into the condenser 5 to cool the condenser 5. At the same time, the cooling water flows into the second adsorption bed 4. After the second adsorption bed 4 is cooled, the pressure drops, enabling the refrigerant that has become gaseous in the evaporator 6 to enter the second adsorption bed 4;

[0058] 2: The first adsorption bed 3 transfers mass to the second adsorption bed 4:

[0059] The mass transfer valve is opened. Since the temperature of the first adsorption bed 3 is relatively high and its pressure is greater than that of the second adsorption bed 4, under the action of the pressure difference, the second adsorption bed 4 and the first adsorption bed 3 conduct heat and mass exchange through the mass transfer valve, providing assistance for the desorption of the second adsorption bed 4 and the adsorption of the first adsorption bed 3;

[0060] 3: The first adsorption bed 3 transfers heat to the second adsorption bed 4:

[0061] The cooling water enters the first adsorption bed 3. Since in the previous process, the first adsorption bed 3 was in a heating state and had a relatively high temperature, the cooling water flowing out of the first adsorption bed 3 has a relatively high temperature, so this part of the cooling water directly enters the hot water tank 10;

[0062] The hot water flows through the second adsorption bed 4. Due to the relatively low temperature of the second adsorption bed 4 in the previous process, the hot water will be cooled. This part of the hot water with a relatively low temperature directly flows into the cooling tower 9. If the heat transfer time is selected appropriately, it can make the outlet temperature of the hot water close to the outlet temperature of the cooling water, indirectly realizing the heat transfer from the first adsorption bed 3 to the second adsorption bed 4;

[0063] 4: The second adsorption bed 4 desorbs, and the first adsorption bed 3 adsorbs

[0064] The second adsorption bed 4 is heated by the hot water in the hot water tank 10. The liquid refrigerant in the second adsorption bed 4 is heated and turned into steam, which is then released and enters the condenser 5. In the condenser 5, it releases heat and condenses into a liquid state. The liquid refrigerant flows into the evaporator 6 and changes from a liquid state to a gaseous state by absorbing heat in the evaporator 6. The refrigeration effect generated during heat absorption is transported by the cold water pipe 7 to the air-cooling mechanism 8 and blown out in the form of cold air by the air-cooling mechanism 8. Meanwhile, the cooling water flows into the condenser 5 to cool the condenser 5. At the same time, the cooling water flows into the first adsorption bed 3. After the first adsorption bed 3 is cooled, the pressure drops, causing the refrigerant that has become gaseous in the evaporator 6 to enter the first adsorption bed 3.

[0065] 5: Mass return from the second adsorption bed 4 to the first adsorption bed 3:

[0066] The mass return valve opens. Since the temperature of the second adsorption bed 4 is relatively high, its pressure is greater than that of the first adsorption bed 3. Under the action of the pressure difference, heat exchange occurs between the first adsorption bed 3 and the second adsorption bed 4 through the mass return valve, providing assistance for the desorption of the first adsorption bed 3 and the adsorption of the second adsorption bed 4.

[0067] 6: Heat return from the second adsorption bed 4 to the first adsorption bed 3:

[0068] The cooling water enters the second adsorption bed 4. Since the second adsorption bed 4 was in a heated state and had a relatively high temperature in the previous process, the cooling water flowing out of the second adsorption bed 4 has a relatively high temperature. Therefore, this part of the cooling water directly enters the hot water tank 10.

[0069] The hot water flows through the first adsorption bed 3. Due to the relatively low temperature of the first adsorption bed 3 in the previous process, the hot water will be cooled. This part of the hot water with a relatively low temperature directly flows into the cooling tower 9. If the heat return time is selected appropriately, it can make the outlet water temperature of the hot water close to the outlet water temperature of the cooling water, indirectly realizing the heat return from the second adsorption bed 4 to the first adsorption bed.

[0070] In addition, the process of the air-cooling mechanism 8 generating cold air:

[0071] Since the cold water pipe 7 is connected to the air-cooling component 802, cold water will be transported to the air-cooling component 802. The fan 807 continuously blows air on the air-cooling component 802. During the air flow process, the cold quantity will be carried away and discharged from the air outlet 803 in the form of cold air, thus realizing the process of generating cold air.

[0072] In summary, the present utility model provides an adsorption type cold air device, which can make full use of waste heat or solar heat, directly produce cold air through the adsorption bed and the air-cooling mechanism, has a simple structure and a good refrigeration effect.
