Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a dehumidification device and an air conditioning system. Background Art

[0002] The air-conditioning system with independent temperature and humidity control can control the indoor temperature and indoor humidity separately, thus avoiding the problems of obvious cooling during the dehumidification process and poor user experience in the existing technical solutions using refrigeration and dehumidification.

[0003] In existing air-conditioning systems with independent temperature and humidity control, dehumidification is often achieved through rotary or solution dehumidification. However, rotary dehumidification requires a high regeneration temperature for the solid adsorbent, making regeneration via hot air alone ineffective. Solution dehumidification, on the other hand, requires utilizing heat of evaporation to lower the liquid temperature and then utilizes heat of condensation to concentrate and regenerate the solution, leading to system complexity and a mismatch between cooling and heating. Therefore, both rotary and solution dehumidification methods inevitably present certain technical challenges.

[0004] Accordingly, the art requires a new dehumidification device and air conditioning system to solve the above problems. Summary of the Invention

[0007] In the preferred technical solution of the above dehumidification device, the reduction coil portion is arranged inside the solid adsorption component.

[0008] In the preferred technical solution of the above dehumidification device, the solid adsorbent is silica gel, molecular sieve, activated alumina or zeolite.

[0009] In the preferred technical solution of the above-mentioned dehumidification device, the reduction component also includes a cooling water tank, in which coolant is stored. The second end of the reduction coil is connected to the cooling water tank, and the cooling water tank is connected to the reduction water tank through a pipeline.

[0010] In the preferred technical solution of the above-mentioned dehumidification device, the reduction component also includes a cooling heat exchanger, which is arranged on the reduction coil and located between the solid adsorption component and the second end of the reduction coil. The cooling heat exchanger is also equipped with a cooling fan.

[0011] In a preferred technical solution of the above-mentioned dehumidification device, the reduction assembly further includes a first throttling element, which is provided on the heat exchange coil and located between the reduction water tank and the second end of the heat exchange coil.

[0012] In the preferred technical solution of the above dehumidification device, an indoor water receiving pan is provided below the indoor heat exchanger of the air-conditioning system, one end of the condensed water pipe is connected to the indoor water receiving pan, and the other end is connected to the reduction water tank or the cooling water tank.

[0013] In the preferred technical solution of the above dehumidification device, the reduction water tank and / or the cooling water tank is further provided with a water supply port, and the water supply port is connected to the water source through a liquid level valve.

[0014] The present invention also provides an air-conditioning system, comprising a compressor, an outdoor heat exchanger, a second throttling element and an indoor heat exchanger, the air-conditioning system further comprising a dehumidification device according to any one of the above-mentioned preferred technical solutions.

[0015] It will be understood by those skilled in the art that, in the preferred technical solution of the present invention, the dehumidification device includes: a dehumidification box, which is provided with a dehumidification air inlet, a dehumidification air outlet, a reduction air inlet and a reduction air outlet, the dehumidification air inlet or the dehumidification air outlet is provided with a dehumidification fan, and the reduction air inlet or the reduction air outlet is provided with a reduction fan; a solid adsorption component, which is fixed in the dehumidification box, and the solid adsorption component includes a solid adsorbent; a reduction component, which includes a reduction coil, and the reduction coil is partially coiled on the solid adsorption component, and the heat exchange medium is allowed to flow through the reduction coil.

[0016] By setting up a dehumidification device, the present application can simplify the device structure and reduce the complexity of the system while ensuring the regeneration effect of the solid adsorbent. Specifically, by setting up a solid adsorption component in the dehumidification box, when indoor dehumidification is required, it is only necessary to turn on the dehumidification fan. At this time, the indoor air enters the dehumidification box through the dehumidification air inlet. When passing through the solid adsorption component, the moisture in the air is adsorbed on the solid adsorbent and becomes dry air, and the dry air returns to the room through the dehumidification air outlet. When the solid adsorption component needs to be regenerated, the reduction fan is turned on, and the indoor air enters the dehumidification box from the reduction air inlet and is discharged to the outside from the reduction air outlet. At this time, the heat exchange medium flowing through the reduction coil is used to heat the solid adsorption component, and the moisture in the solid adsorption component is heated by the heat exchange medium and evaporated into water vapor, which is finally discharged to the outside together with the indoor air under the drive of the reduction fan.

[0017] Furthermore, by providing a reduction water tank and heat exchange coil within the reduction assembly, when the solid adsorption assembly needs to be regenerated, the high-temperature refrigerant discharged from the compressor during operation of the air conditioning system can be used to heat the heat exchange liquid in the reduction water tank via the heat exchange coil. A circulating pump can then be used to circulate the heat exchange liquid to achieve heating and regeneration of the solid adsorption assembly. Furthermore, because some of the refrigerant can also exchange heat with the heat exchange liquid in the reduction water tank via the heat exchange coil, this application can also enhance the refrigerant's heat exchange effect, improve the operating efficiency of the air conditioning system, and reduce air conditioning operating energy consumption.

[0018] Furthermore, by partially arranging the reduction coil inside the solid adsorption component, the regeneration efficiency of the solid adsorption component can be improved and the regeneration effect can be ensured.

[0019] Furthermore, by installing a cooling water tank, a cooling heat exchanger, and a cooling fan on the recovery coil, the heat exchange liquid can be kept at an appropriate temperature while preventing excessive evaporation and water shortages caused by excessively high liquid temperatures, thereby improving regeneration stability. Furthermore, the cooling water tank further enhances the refrigerant's heat exchange efficiency, improving the air conditioner's operating efficiency and reducing energy consumption.

[0020] Furthermore, by setting a first throttling element on the heat exchange coil, the regeneration process of the solid adsorption component can be operated independently without the help of the cooling mode of the air-conditioning system, thereby avoiding the decline in user experience caused by the reduction in indoor temperature during the regeneration process.

[0021] Furthermore, by directing condensed water into the reduction water tank or cooling water tank, the dehumidification device of the present application can further utilize the condensed water generated during the air conditioning cycle, reducing water waste and the amount of water replenishment. Furthermore, due to its lower temperature, the condensed water can further cool the liquid in the reduction water tank or cooling water tank, further improving the heat exchange efficiency of the refrigerant.

[0022] Furthermore, by arranging a dehumidification device in the air-conditioning system, the air-conditioning system can realize independent control of indoor temperature and humidity, and the dehumidification device can complement the air-conditioning system to realize the regeneration of the solid adsorption component and the reduction of energy consumption.

[0033] Example 1

[0034] First refer to Figure 1 , the air conditioning system of the present invention is described. Figure 1 This is a system diagram of a first embodiment of an air-conditioning system according to the present invention.

[0035] like Figure 1 As shown, to address the issues of poor regeneration performance and system complexity caused by solution dehumidification in existing rotary dehumidification systems, the air conditioning system of the present application primarily comprises a compressor 1, an outdoor heat exchanger 2, an outdoor fan 21, a second throttling element 3, an indoor heat exchanger 4, an indoor fan 41, and a master controller 6. The compressor 1, outdoor heat exchanger 2, outdoor fan 21, second throttling element 3, and master controller 6 are housed in the outdoor unit's chassis 22, while the indoor heat exchanger 4 and indoor fan 41 are housed in the indoor unit. The compressor 1, outdoor heat exchanger 2, second throttling element 3, and indoor heat exchanger 4 are connected via refrigerant pipes to form a refrigerant circulation system. A first electrically controlled valve 11 is provided at the exhaust port of the compressor 1. The master controller 6 is connected to the compressor 1, outdoor fan 21, first electrically controlled valve 11, second throttling element 3, and indoor fan 41 to control the operation of these components. In this embodiment, the second throttling element 3 can be a valve with controllable opening, such as an electronic expansion valve, and the first electrically controlled valve 11 can be a valve that can be opened and closed, such as a solenoid valve.

[0036] It should be noted that in order to clearly describe the connection relationship between the above components, the components of the outdoor unit are broken up and drawn in the attached figure. Figure 1Those skilled in the art will appreciate that the locations of these components shown in the drawings are not their actual locations.

[0037] Continue to refer to Figure 1 In particular, the air conditioning system of the present application further includes a dehumidification device 5, which includes a dehumidification box 51, a solid adsorption component 52, and a reduction component (not shown in the figure). The dehumidification box 51 is provided with a dehumidification air inlet 511, a dehumidification air outlet 512, a reduction air inlet 513, and a reduction air outlet 514. The dehumidification air inlet 511 and the dehumidification air outlet 512 are respectively connected to the indoor room. The dehumidification air outlet 512 is provided with a dehumidification fan 515. The reduction air inlet 513 is connected to the indoor room, and the reduction air outlet 514 is connected to the outdoor room. The reduction air outlet 514 is provided with a reduction fan 516. The solid adsorption component 52 is fixed in the dehumidification box 51 and includes a solid adsorbent. The reduction assembly includes a reduction coil 54, which is partially coiled around the solid adsorption assembly 52. The first end of the reduction coil 54 is connected to the exhaust port of the compressor 1, and the second end is connected to the inlet of the outdoor heat exchanger 2, so that the reduction coil 54 allows the refrigerant (i.e., the heat exchange medium) to flow through it. In addition, a second electrically controlled valve 552 is provided near the first end of the reduction coil 54. The master controller 6 is also connected to the dehumidification fan 515, the reduction fan 516, and the second electrically controlled valve 552, respectively, to control the operation of the above-mentioned components. Among them, the second electrically controlled valve 552 in this embodiment can be a valve body such as a solenoid valve that can realize the opening and closing function.

[0038] When the indoor temperature needs to be lowered, the master controller 6 starts the compressor 1, the outdoor fan 21, and the indoor fan 41, controls the first electrically controlled valve 11 to open, the second electrically controlled valve 552 to close, and the second throttling element 3 to open to the set opening. Compressor 1 discharges high-temperature, high-pressure gaseous refrigerant, which enters the outdoor heat exchanger 2 for further heat exchange with the outdoor air and becomes a medium-temperature, high-pressure liquid refrigerant. The medium-temperature, high-pressure liquid refrigerant passes through the second throttling element 3 and becomes a low-temperature, low-pressure gas-liquid two-phase refrigerant. The low-temperature, low-pressure gas-liquid two-phase refrigerant enters the indoor heat exchanger 4 for heat exchange with the indoor air and becomes a low-temperature, low-pressure gaseous refrigerant, which then drops the indoor temperature. The low-temperature, low-pressure gaseous refrigerant then returns to the compressor 1 through the intake port, completing the refrigerant cycle.

[0039] When dehumidification is required indoors, the main controller 6 controls the dehumidification fan 515 to start running. Driven by the dehumidification fan 515, the indoor air enters the dehumidification box 51 from the dehumidification air inlet 511, and when passing through the solid adsorption component 52, the moisture in the air is adsorbed on the solid adsorbent and becomes dry air. The dry air returns to the room through the dehumidification air outlet 512, and the indoor humidity decreases accordingly.

[0040] When the solid adsorption assembly 52 absorbs a certain amount of moisture and needs to be regenerated, the main controller 6 controls the compressor 1, the external fan 21, the internal fan 41, and the reduction fan 516 to start, controls the first electrically controlled valve 11 to close, the second electrically controlled valve 552 to open, and the second throttling element 3 to open to the set opening. Indoor air enters the dehumidification box 51 from the reduction air inlet 513 and is discharged to the outside from the reduction air outlet 514. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor 1 first circulates to the solid adsorption assembly 52 through the reduction coil 54 and then continues the normal refrigeration cycle. The moisture in the solid adsorption assembly 52 is heated by the high-temperature and high-pressure refrigerant and evaporated into water vapor and precipitated. The precipitated water vapor is discharged to the outside along with the indoor air, and the solid adsorption assembly 52 is regenerated.

[0041] It can be seen from the above description that through the setting of the dehumidification device 5, the air-conditioning system of the present application can improve the regeneration effect of the solid adsorption component 52 by utilizing the high-temperature and high-pressure gaseous refrigerant discharged by the compressor 1 to heat the solid adsorption component 52, while achieving independent control of temperature and humidity. The above structure is simple and highly feasible.

[0042] Example 2

[0043] Refer to the following Figure 2 , a more preferred implementation method of the present application is introduced. Among them, Figure 2 This is a system diagram of a second embodiment of the air-conditioning system of the present invention.

[0044] like Figure 2 As shown, in a preferred embodiment, the air conditioning system primarily includes a compressor 1, an outdoor heat exchanger 2, an outdoor fan 21, a second throttling element 3, an indoor heat exchanger 4, an indoor fan 41, an indoor water collection pan 42, a condensate pipe 43, and a master controller 6. The compressor 1, outdoor heat exchanger 2, outdoor fan 21, second throttling element 3, and master controller 6 are housed in the outdoor unit's chassis 22, while the indoor heat exchanger 4, indoor fan 41, and indoor water collection pan 42 are housed in the indoor unit. One end of the condensate pipe 43 is connected to the indoor water collection pan 42 and the other end is led outdoors. A refrigerant pipe connects the compressor 1, outdoor heat exchanger 2, second throttling element 3, and indoor heat exchanger 4 to form a refrigerant circulation system. A first electrically controlled valve 11 is also provided at the exhaust port of the compressor 1. The master controller 6 is connected to the compressor 1, outdoor fan 21, first electrically controlled valve 11, second throttling element 3, and indoor fan 41, respectively, to control the operation of the aforementioned components. In this embodiment, the second throttling element 3 may be a valve body with controllable opening, such as an electronic expansion valve, and the first electrically controlled valve 11 may be a valve body that can be opened and closed, such as a solenoid valve.

[0045] Continue to refer to Figure 2The air conditioning system also includes a dehumidification device 5, which includes a dehumidification tank 51, a solid adsorption assembly 52, and a reduction assembly (not shown). The solid adsorption assembly 52 includes a solid adsorbent, and the reduction assembly includes a reduction water tank 53, a reduction coil 54, a heat exchange coil 55, a cooling water tank 56, a cooling heat exchanger 58, and a cooling fan 581. The dehumidification tank 51 and the solid adsorption assembly 52 are located indoors, such as in an indoor unit or separately indoors, while the reduction water tank 53, the cooling water tank 56, and the cooling heat exchanger 58 are located outdoors, such as in an outdoor unit housing 22 or separately outdoors.

[0046] The dehumidification box 51 is provided with a dehumidification air inlet 511, a dehumidification air outlet 512, a reduction air inlet 513 and a reduction air outlet 514. The dehumidification air inlet 511 and the dehumidification air outlet 512 are respectively connected to the indoor space. The dehumidification air outlet 512 is provided with a dehumidification fan 515. The reduction air inlet 513 is connected to the indoor space. The reduction air outlet 514 is connected to the outdoor space. The reduction air outlet 514 is provided with a reduction fan 516.

[0047] The solid adsorption assembly 52 is fixedly installed in the dehumidification box 51. The solid adsorption assembly 52 includes a solid adsorbent. In this embodiment, the solid adsorbent can be silica gel, molecular sieve, activated alumina or zeolite. The solid adsorption assembly 52 is formed by bonding, splicing or pressing one or more of the above solid adsorbents. The reduction coil 54 is partially coiled on the solid adsorption assembly 52. Specifically, the reduction coil 54 is partially coiled inside the solid adsorption assembly 52. Figure 2 As shown in FIG, the reduction coil 54 is partially coiled in an S-shaped manner inside the solid adsorption assembly 52. For example, the solid adsorption assembly 52 and part of the reduction coil 54 are press-formed together, or a hole is left inside the solid adsorption assembly 52 during the molding process to allow the reduction coil 54 to pass through, so that the reduction coil 54 can be installed after the solid adsorption assembly 52 is formed.

[0048] By partially coiling the reduction coil 54 inside the solid adsorption component 52, and further coiling it in an S-shape inside the solid adsorption component 52, the coil is in direct contact with the solid adsorption component 52, which can improve the regeneration efficiency of the solid adsorption component 52 and ensure the regeneration effect.

[0049] Still refer to Figure 2The reduction water tank 53 contains a heat exchange liquid (i.e., a heat exchange medium), such as water or brine. The reduction coil 54 is arranged behind the solid adsorption assembly 52. Its first end is connected to the reduction water tank 53, and its second end is connected to the cooling water tank 56. The cooling water tank 56 contains a coolant, such as water or brine. The cooling water tank 56 is connected to the reduction water tank 53 via a pipe 561 and is installed at a higher height than the reduction water tank 53. A circulation pump 541 is provided near the first end of the reduction coil 54, and a cooling heat exchanger 58 is provided near the second end. The cooling heat exchanger 58 is equipped with a cooling fan 581 and is preferably a plate heat exchanger. The heat exchange coil 55 is partially arranged within the reduction water tank 53, and the portion arranged within the reduction water tank 53 is S-shaped. After the heat exchange coil 55 is installed, its first end extends out of the reduction water tank 53 and communicates with the exhaust port of the air conditioning system's compressor 1. Its second end extends out of the reduction water tank 53 and communicates with the inlet of the air conditioning system's outdoor heat exchanger 2. A second electrically controlled valve 552, such as a solenoid valve, is located near the first end of the heat exchange coil 55. A valve body capable of opening and closing is also provided. A first throttling element 551, such as an electronic expansion valve, is also located near the second end of the heat exchange coil 55. The first electrically controlled valve 11 is located on the refrigerant pipe between the first and second ends of the heat exchange coil 55.

[0050] By providing a reduction water tank 53 and a heat exchange coil 55 in the reduction assembly, when the solid adsorption assembly 52 needs to be regenerated, the high-temperature refrigerant discharged from the compressor 1 during the operation of the air-conditioning system can be used to heat the heat exchange liquid in the reduction water tank 53 through the heat exchange coil 55, and then the circulation pump 541 is used to drive the heat exchange liquid to circulate to achieve heating and regeneration of the solid adsorption assembly 52. By providing a cooling water tank 56 and providing a cooling heat exchanger 58 and a cooling fan 581 on the reduction coil 54, it is possible to prevent the occurrence of excessive evaporation and water shortage caused by excessively high heat exchange liquid temperature while ensuring that the heat exchange liquid is at an appropriate heating temperature, thereby improving regeneration stability. In addition, the provision of the cooling water tank 56 can further enhance the heat exchange effect of the refrigerant, improve the operating efficiency of the air conditioner, and reduce operating energy consumption. By setting a first electrically controlled valve 11 at the exhaust port of the compressor 1 and respectively setting a first throttling element 551 and a second electrically controlled valve 552 at different positions of the heat exchange coil 55, the regeneration process of the solid adsorption component 52 can be operated independently without the need for the refrigeration mode, thereby avoiding a decrease in user experience caused by a decrease in indoor temperature during the regeneration process of the solid adsorption component 52.

[0051] Continue to refer to Figure 2The cooling water tank 56 also has a water inlet (not shown) on its sidewall. This inlet connects to the municipal water supply via a liquid level valve 562. The inlet should be positioned as close to the bottom of the cooling water tank 56 as possible while ensuring adequate water circulation. In this embodiment, the liquid level valve 562 is a valve that automatically opens and closes based on the liquid level within the cooling water tank 56. For example, the liquid level valve 562 can be a ball valve or a combination of a liquid level sensor and a solenoid valve. Furthermore, the condensate pipe 43 is connected to the cooling water tank 56 after exiting the room.

[0052] By directing condensed water into the cooling water tank 56, the dehumidifier 5 of the present application can further utilize the condensed water generated during the air conditioning cycle, reducing water waste and the amount of water replenishment required. Furthermore, due to its lower temperature, the condensed water can further cool the liquid in the reduction water tank 53 or the cooling water tank 56, further improving the heat exchange efficiency of the refrigerant. The water replenishment port is positioned as close as possible to the bottom of the cooling water tank 56, allowing the dehumidifier 5 of the present application to maximize municipal water conservation while ensuring water supply, prioritizing the use of condensed water.

[0053] Still refer to Figure 2 The main controller 6 of the air-conditioning system is also connected to the dehumidification fan 515, the reduction fan 516, the circulation pump 541, the first throttling element 551, the second electric control valve 552 and the cooling fan 581 respectively to control the operation of the above components.

[0054] The dehumidification device 5 is connected to the dehumidification fan 515, the reduction fan 516, the circulation pump 541, the first throttling element 551, the second electric control valve 552 and the cooling fan 581 through the main controller 6, so that the dehumidification device 5 can operate automatically and realize the combined control of temperature and humidity, thereby improving the degree of automation of the air-conditioning system.

[0055] Refer to the following Figure 2 , the operation process of the air-conditioning system in this embodiment is briefly described.

[0056] like Figure 2As shown, when the indoor temperature needs to be lowered, the main controller 6 controls the compressor 1, the outdoor fan 21, the indoor fan 41, the cooling fan 581 and the circulation pump 541 to start, controls the first electric control valve 11 to close, the second electric control valve 552 to open, the first throttling element 551 to fully open, and the second throttling element 3 to open to the set opening. Circulating pump 541 circulates the heat exchange liquid between the reduction water tank 53 and the cooling water tank 56. Compressor 1 discharges high-temperature, high-pressure gaseous refrigerant, which then enters the reduction water tank 53 through heat exchange coil 55. It then undergoes heat exchange with the heat exchange liquid within the reduction water tank 53 before entering the outdoor heat exchanger 2. The refrigerant in outdoor heat exchanger 2 undergoes further heat exchange with the outdoor air, transforming into medium-temperature, high-pressure liquid refrigerant. This medium-temperature, high-pressure liquid refrigerant is throttled by the second throttling element 3 and transformed into a low-temperature, low-pressure gas-liquid two-phase refrigerant. This low-temperature, low-pressure gas-liquid two-phase refrigerant then enters the indoor heat exchanger 4, where it undergoes heat exchange with the indoor air and transforms into a low-temperature, low-pressure gaseous refrigerant, thereby lowering the indoor temperature. The low-temperature, low-pressure gaseous refrigerant then returns to compressor 1 through the intake port, completing the refrigerant cycle.

[0057] When dehumidification is required indoors, the main controller 6 controls the dehumidification fan 515 to start running. Driven by the dehumidification fan 515, the indoor air enters the dehumidification box 51 from the dehumidification air inlet 511, and when passing through the solid adsorption component 52, the moisture in the air is adsorbed on the solid adsorbent and becomes dry air. The dry air returns to the room through the dehumidification air outlet 512, and the indoor humidity decreases accordingly.

[0058] When the solid adsorption component 52 adsorbs a certain amount of moisture and needs to be regenerated, if the cooling mode of the air-conditioning system is running, that is, the compressor 1, the outdoor fan 21, the indoor fan 41, the cooling fan 581 and the circulation pump 541 are running, and the first electric control valve 11 is closed, the second electric control valve 552 is open, the first throttling element 551 is fully open, and the second throttling element 3 is opened to the set opening, then at this time the main controller 6 continues to control the reduction fan 516 to start, and the refrigerant follows the refrigeration cycle, and the indoor air enters the dehumidification box 51 from the reduction air inlet 513 and is discharged to the outdoors from the reduction air outlet 514. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 enters the reduction water tank 53 through the heat exchange coil 55 and heats the heat exchange liquid in the reduction water tank 53. The circulation pump 541 drives the heat exchange liquid to circulate between the reduction water tank 53 and the cooling water tank 56. When the heat exchange liquid is heated to a higher temperature and circulates to the solid adsorption component 52, the moisture in the solid adsorption component 52 is heated by the heat exchange liquid and evaporated into water vapor and precipitated. The precipitated water vapor is discharged to the outside together with the indoor air, and the solid adsorption component 52 is regenerated.

[0059] If the air-conditioning system is not operating in cooling mode, the main controller 6 controls the compressor 1, the outdoor fan 21, the cooling fan 581, the reduction fan 516 and the circulation pump 541 to start, and controls the first electric control valve 11 to close, the second electric control valve 552 to open, the first throttling element 551 to open to a certain degree, and the second throttling element 3 to be fully opened. The indoor air enters the dehumidification box 51 from the reduction air inlet 513 and is discharged to the outside from the reduction air outlet 514. The high-temperature, high-pressure gaseous refrigerant discharged from compressor 1 passes through heat exchange coil 55 and enters reduction water tank 53. After heat exchange with the heat exchange liquid in reduction water tank 53, it becomes medium-temperature, high-pressure liquid refrigerant. After being throttled by first throttling element 551, the medium-temperature, high-pressure liquid refrigerant becomes low-temperature, low-pressure, gas-liquid two-phase refrigerant. The low-temperature, low-pressure gas-liquid two-phase refrigerant enters outdoor heat exchanger 2, where it exchanges heat with the outdoor air and becomes low-temperature, low-pressure gaseous refrigerant. The low-temperature, low-pressure gaseous refrigerant then passes through indoor heat exchanger 4 and returns to compressor 1 through the intake port, completing the refrigerant cycle. A circulating pump 541 circulates the heated heat exchange liquid between reduction water tank 53 and cooling water tank 56. When the heat exchange liquid reaches a higher temperature and circulates to solid adsorption assembly 52, the water in the solid adsorption assembly 52 is heated by the heat exchange liquid and evaporates into water vapor, which is then discharged outdoors along with the indoor air, regenerating the solid adsorption assembly 52.

[0060] It should be noted that the above preferred embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art may adjust the above settings so that the present invention can be applied to more specific application scenarios.

[0061] For example, in an alternative embodiment, the dehumidification fan 515 and the reduction fan 516 are not positioned in a single location. As long as the indoor air can pass through the solid adsorption assembly 52, the locations of the two can be changed. For example, the dehumidification fan 515 can be positioned at the dehumidification air inlet 511, and the reduction fan 516 can be positioned at the reduction air inlet 513, etc.

[0062] For another example, in another alternative embodiment, although the reduction coil 54 is described as being partially coiled inside the solid adsorption assembly 52 and arranged in an S-shape, those skilled in the art may adjust the arrangement as long as the adjusted arrangement allows the reduction coil 54 to heat the solid adsorption assembly 52. For example, the reduction coil 54 may be wound along the outer surface of the solid adsorption assembly 52, or spirally coiled inside the solid adsorption assembly 52.

[0063] For example, in another replaceable embodiment, in order to achieve better technical effects for the technical solution of the present application, those skilled in the art may also add additional components in a targeted manner on the basis of the present embodiment. Such adjustments commonly used in the art do not deviate from the principles of the present application. For example, in order to improve the flow effect of the flowing air entering the dehumidification box 51 during the dehumidification process and the regeneration process, those skilled in the art may respectively set inlet / outlet valves on the dehumidification air inlet 511, the dehumidification air outlet 512, the reduction air inlet 513 and the reduction air outlet 514, thereby controlling the air flow direction by controlling the opening and closing of the inlet / outlet valves during the dehumidification process and the regeneration process; for example, in order to improve the contact effect between the flowing air and the solid adsorption component 52, those skilled in the art may also set a plurality of baffles in the dehumidification box 51, so that the airflow entering the dehumidification box 51 repeatedly passes through the solid adsorption component 52 according to the path defined by the baffles, thereby improving the utilization rate and adsorption effect of the solid adsorption component 52.

[0064] For example, in another alternative embodiment, although the water supply port is arranged on the side wall of the cooling water tank 56 in the above embodiment, the setting position of the water supply port is not unique. Those skilled in the art can also set the water supply port at other positions, such as on the reduction water tank 53.

[0065] For example, in another alternative embodiment, those skilled in the art may selectively omit one or more of the following components in a specific application to enable the present application to meet different application scenarios. Components include, but are not limited to: a cooling water tank 56, a cooling heat exchanger 58, a cooling fan 581, a first electrically controlled valve 11, a second electrically controlled valve 552, a first throttling element 551, an indoor water receiving tray 42, and a condensing water pipe 43. For example, when the cooling water tank 56 is omitted, both ends of the reduction coil 54 can be simultaneously connected to the reduction water tank 53. At this time, since the heat exchange liquid circulates only between the reduction water tank 53 and the reduction coil 54, the regeneration effect of the solid adsorption assembly 52 can be improved.

[0066] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.

[0067] Example 3

[0068] The following combination Figure 3 , another alternative embodiment of the present invention is introduced. Among them, Figure 3 This is a system diagram of a third embodiment of the air-conditioning system of the present invention.

[0069] like Figure 3As shown, the difference between this embodiment and embodiment 2 is that the water inlet of the cooling water tank 56 is arranged on the side wall away from the bottom of the cooling water tank 56. This arrangement ensures the amount of water in the cooling water tank 56 when the air conditioning system is in operation, thereby improving the heat exchange effect between the refrigerant in the reduction water tank 53 and the heat exchange liquid, improving the efficiency of the air conditioning system, and further reducing energy consumption.

[0070] Example 4

[0071] The following combination Figure 4 , an alternative embodiment of the present invention is introduced. Among them, Figure 4 This is a system diagram of a fourth embodiment of the air-conditioning system of the present invention.

[0072] like Figure 4 As shown, this embodiment differs from Embodiment 3 in that the condensed water pipe 43 is led outdoors and then connected to the reduction water tank 53. This arrangement can improve the heat exchange between the refrigerant in the reduction water tank 53 and the heat exchange liquid, thereby increasing the operating efficiency of the air conditioning system and reducing system energy consumption.

[0073] Those skilled in the art will appreciate that the master controller 6 also includes some other well-known structures, such as a processor, a controller, and a memory. The memory includes but is not limited to a random access memory, a flash memory, a read-only memory, a programmable read-only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory, or a register. The processor includes but is not limited to a CPLD / FPGA, a DSP, an ARM processor, a MIPS processor, etc. To unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.

[0074] Furthermore, those skilled in the art will appreciate that although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of the present invention and to form different embodiments. For example, in the claims of the present invention, any of the claimed embodiments may be used in any combination.

[0075] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
