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 using photovoltaic power supply. Background Art

[0002] With the rapid development of my country's economy and the continuous improvement of the quality of life, the popularity of air conditioners is increasing. When people use air conditioners, in addition to using them to adjust the indoor temperature, they are also paying more and more attention to regulating the indoor humidity.

[0003] However, traditional air conditioners often use cooling mode to regulate humidity. This involves using a low-temperature refrigerant, below the air's dew point, to exchange heat with the indoor air, condensing the moisture into liquid form before discharging it. However, this dehumidification method not only causes a sudden drop in indoor temperature, impairing user experience, but also significantly increases power consumption, resulting in energy waste.

[0004] Accordingly, the art needs a new dehumidification device and air conditioning system using photovoltaic power supply to solve the above problems. Summary of the Invention

[0008] In the preferred technical solution of the above-mentioned dehumidification device using photovoltaic power supply, the photovoltaic assembly also includes a power storage component and a solar controller. The photovoltaic panel is connected to the power storage component through the solar controller, and the power storage component is connected to the main controller of the air-conditioning system. The main controller is respectively connected to the dehumidification fan and the reduction fan.

[0010] In the preferred technical solution of the above-mentioned dehumidification device using photovoltaic power supply, 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 the preferred technical solution of the above-mentioned dehumidification device using photovoltaic power supply, the reduction component also includes a first throttling element, which is arranged 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-mentioned dehumidification device using photovoltaic power supply, an indoor water receiving pan is provided under the indoor heat exchanger of the air-conditioning system, and the indoor water receiving pan is equipped with a condensation water pipe.

[0013] In the preferred technical solution of the above-mentioned photovoltaic-powered dehumidification device, the reduction coil is partially arranged inside the solid adsorption component; and / or the solid adsorbent is silica gel, molecular sieve, activated alumina or zeolite.

[0014] The present application also provides an air-conditioning system, including a compressor, an outdoor heat exchanger, a second throttling element and an indoor heat exchanger. The air-conditioning system also includes a photovoltaic-powered dehumidification device as described in 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 heat exchange medium is allowed to flow through the reduction coil; a photovoltaic component, which is respectively connected to the dehumidification fan and the reduction fan to supply power to the dehumidification fan and the reduction fan.

[0016] By setting up a dehumidification device, the present application can achieve independent regulation of indoor temperature and humidity, reduce power consumption, and save energy. Specifically, by setting up a solid adsorption component in the dehumidification box, when indoor dehumidification is required, there is no need to start the air conditioner and run the cooling mode. 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. The dry air returns to the room through the dehumidification outlet, achieving indoor dehumidification and reducing energy consumption. 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 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. Finally, it is discharged to the outside together with the indoor air under the drive of the reduction fan, thereby achieving regeneration of the solid adsorption component.

[0017] By setting up photovoltaic modules and using them to power the dehumidification fan and the reduction fan, the dehumidification process and the reduction process of the dehumidification device can both be powered by the photovoltaic modules, achieving zero energy consumption.

[0018] 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. This heat exchange liquid can then be circulated by a circulating pump 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 enhance the refrigerant's heat exchange effect during air conditioning operation, improving the operating efficiency of the air conditioning system and reducing air conditioning energy consumption.

[0019] Furthermore, by setting a water collector and a water collecting pipe under the photovoltaic panel, rainwater can be collected cleverly with the help of the photovoltaic panel, so that the heat exchange liquid in the reduction water tank can be provided by the collected rainwater, realizing the utilization of natural resources and saving water resources.

[0020] Furthermore, by setting up power storage components in the photovoltaic modules, the electric energy converted by the photovoltaic modules can be stored and utilized, avoiding the inability to use the photovoltaic modules to start the dehumidification fan and the reduction fan when the light intensity is insufficient, thereby further saving electricity.

[0021] 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.

[0022] 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 heating temperature while preventing excessive evaporation and water shortages caused by excessively high heat exchange liquid temperatures, thereby improving regeneration stability. Furthermore, the cooling water tank further enhances the refrigerant's heat exchange during air conditioning operation, improving its operating efficiency and reducing its energy consumption.

[0023] 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.

[0024] 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.

[0025] 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.

[0036] Example 1

[0037] 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.

[0038] like Figure 1 As shown, to address the poor user experience and high energy consumption of existing air conditioning dehumidification methods, the air conditioning system of the present application 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, 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.

[0039] 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 1 Those skilled in the art will appreciate that the locations of these components shown in the drawings are not their actual locations.

[0040] Continue to refer to Figure 1In 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, a reduction component (not shown in the figure), and a photovoltaic component 57. 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 component includes a reduction coil 54, which is partially coiled on the solid adsorption component 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 photovoltaic component 57 is respectively connected to the dehumidification fan 515 and the reduction fan 516 to supply power to the above components. The main controller 6 is also respectively connected to the dehumidification fan 515, the reduction fan 516 and the second electrically controlled valve 552 to control the operation of the above 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.

[0041] 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.

[0042] When dehumidification is required indoors, the photovoltaic module 57 supplies power to the dehumidification fan 515, and 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.

[0043] When the solid adsorption component 52 absorbs a certain amount of moisture and needs to be regenerated, the photovoltaic component 57 supplies power to the reduction fan 516, and 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 component 52 through the heat exchange coil 55 and then continues the normal refrigeration cycle. The moisture in the solid adsorption component 52 is heated by the high-temperature and high-pressure refrigerant and evaporates into water vapor and precipitates. The precipitated water vapor is discharged to the outside along with the indoor air, and the solid adsorption component 52 is regenerated.

[0044] As can be seen from the above description, by providing the dehumidification device 5, the air conditioning system of the present application can achieve independent control of indoor temperature and humidity, reduce system power consumption, and save energy. The regeneration effect of the solid adsorption component 52 is improved by using the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 to heat the solid adsorption component 52. By providing a photovoltaic component 57 and using the photovoltaic component 57 to power the dehumidification fan 515 and the reduction fan 516, the dehumidification process and the reduction process of the dehumidification device 5 can both be powered by the photovoltaic component 57, achieving zero energy consumption.

[0045] Example 2

[0046] 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.

[0047] like Figure 2As 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.

[0048] Continue to refer to Figure 2 The air conditioning system further includes a dehumidification device 5, which includes a dehumidification tank 51, a solid adsorption assembly 52, a reduction assembly (not shown), and a photovoltaic assembly 57. The solid adsorption assembly 52 includes a solid adsorbent, 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, and the photovoltaic assembly 57 includes a photovoltaic panel 571, a power storage component 572, and a solar controller 573. 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, the cooling heat exchanger 58, the photovoltaic panel 571, the power storage component 572, and the solar controller 573 are located outdoors, such as in an outdoor unit housing 22 or separately outdoors.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Still refer to Figure 2 The 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.

[0053] 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.

[0054] Continue to refer to Figure 2 After being led outdoors, the condensed water pipe 43 is connected to the cooling water tank 56. A water inlet (not shown) is also provided on the side wall of the cooling water tank 56. The water inlet is connected to the municipal water supply via a liquid level valve 562. The height of the water inlet can be set as close to the bottom of the cooling water tank 56 as possible while ensuring sufficient water circulation. In this embodiment, the liquid level valve 562 refers to a valve body that can be automatically opened and closed by the liquid level in the cooling water tank 56. For example, the liquid level valve 562 can be a liquid level ball valve or a combination of a liquid level sensor and a solenoid valve.

[0055] By directing the 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. Furthermore, due to its lower temperature, the condensed water can further reduce the temperature of the liquid in the reduction water tank 53 or the cooling water tank 56, further improving the heat exchange effect of the refrigerant.

[0056] Continue to refer to Figure 2The photovoltaic assembly 57 includes a photovoltaic panel 571, a power storage component 572, and a solar controller 573. The photovoltaic panel 571 is connected to the power storage component 572 via the solar controller 573, and the power storage component 572 is connected to the main controller 6 of the air-conditioning system. Specifically, the photovoltaic panel 571 in this application is formed by combining single-crystal silicon or polycrystalline silicon cells into a plate shape, which converts light energy into electrical energy through the photoelectric effect for utilization. The power storage component 572 preferably adopts a battery pack, which includes a plurality of batteries. The photovoltaic panel 571 is connected to the battery pack via the solar controller 573, and the battery pack is connected to the main controller 6 via a connecting line, thereby realizing the storage and utilization of the electrical energy after photoelectric conversion, such as directly using the electrical energy converted by photoelectric conversion for the operation of the various electrical components of the air-conditioning system or using the electrical energy stored in the battery pack for the operation of the various electrical components of the air-conditioning system. Among them, the photovoltaic power generation and current processing process are well known technologies in the art and will not be described in detail here. The dehumidification device 5 also includes a water collector 574 and a water collecting pipe 575. The water collector 574 can be disc-shaped or funnel-shaped, and is arranged below the photovoltaic panel 571 to collect rainwater intercepted by the photovoltaic panel 571. The first end of the water collecting pipe 575 is connected to the water collector 574, and the second end is connected to the cooling water tank 56 to drain the collected rainwater into the cooling water tank 56.

[0057] By using photovoltaic panels 571 and a battery pack to power the electrical components of the air conditioning system, the air conditioning system's energy consumption can be significantly reduced during operation, even achieving zero energy consumption. By providing a power storage component 572 within the photovoltaic assembly 57, the electrical energy converted by the photovoltaic assembly 57 can be stored and utilized, preventing the photovoltaic assembly 57 from being unable to activate the fan and circulation pump 541 when light intensity is insufficient, further saving energy. By providing a water collector 574 and a water collection pipe 575 below the photovoltaic panel 571, rainwater is cleverly collected using the photovoltaic panel 571, allowing the heat exchange liquid in the cooling water tank 56 to be supplied by collected rainwater, thus utilizing natural resources and conserving water. Furthermore, by positioning the water inlet as close as possible to the bottom of the cooling water tank 56, the dehumidification device 5 of the present application can maximize the conservation of municipal water resources while ensuring the amount of circulating water, prioritizing the use of collected rainwater and condensed water discharged from the indoor environment.

[0058] Of course, since the electric energy converted by the photovoltaic module 57 may not meet the needs of all electrical components, although not shown in the figure, corresponding AC power is still required, but in this embodiment, the electric energy converted and stored by the photovoltaic module 57 is preferentially used.

[0059] Still refer to Figure 2The 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.

[0060] 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 of the air-conditioning system, thereby improving the degree of automation of the air-conditioning system.

[0061] Refer to the following Figure 2 , the operation process of the air-conditioning system in this embodiment is briefly described.

[0062] like Figure 2 As 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 electrically controlled valve 11 to be closed, the second electrically controlled valve 552 to be opened, the first throttling element 551 to be fully opened, and the second throttling element 3 to be opened to the set opening, and preferentially uses the electric energy converted by the photovoltaic panel 571 and the electric energy stored in the battery to power the above components. 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 entering the 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. This lowers the indoor temperature, achieving indoor cooling. The low-temperature, low-pressure gaseous refrigerant then returns to compressor 1 through the intake port, completing the refrigerant cycle.

[0063] When dehumidification is required, the master controller 6 activates the dehumidification fan 515, preferentially using the electricity converted by the photovoltaic panels 571 and the electricity stored in the battery to power the dehumidification fan 515. Driven by the dehumidification fan 515, the indoor air enters the dehumidification chamber 51 through the dehumidification air inlet 511. As it passes through the solid adsorption assembly 52, the moisture in the air is adsorbed on the solid adsorbent, turning it into dry air. The dry air then returns to the room through the dehumidification air outlet 512, reducing the indoor humidity and achieving dehumidification.

[0064] When the solid adsorption assembly 52 absorbs a certain amount of moisture and requires regeneration, if the air conditioning system is operating in cooling mode (i.e., the compressor 1, outdoor fan 21, indoor fan 41, cooling fan 581, and circulation pump 541 are operating), and the first electrically controlled valve 11 is closed, the second electrically controlled valve 552 is open, the first throttle element 551 is fully open, and the second throttle element 3 is opened to the set opening), the master controller 6 then continues to control the activation of the reduction fan 516 and preferentially uses the electricity converted by the photovoltaic panel 571 and the electricity stored in the battery to power the various components. At this point, the refrigerant follows the refrigeration cycle, with indoor air entering the dehumidification tank 51 through the reduction air inlet 513 and being discharged outdoors through the reduction air outlet 514. The high-temperature, high-pressure gaseous refrigerant discharged from the compressor 1 enters the reduction water tank 53 through the heat exchange coil 55, heating the heat exchange liquid within. 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 circulated 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 along with the indoor air, and the solid adsorption component 52 is regenerated.

[0065] If the air conditioning system is not operating in cooling mode, the master controller 6 activates the compressor 1, outdoor fan 21, cooling fan 581, recovery fan 516, and circulation pump 541. It also controls the closing of the first electrically controlled valve 11, the opening of the second electrically controlled valve 552, the opening of the first throttle element 551 to a certain degree, and the full opening of the second throttle element 3. The system then prioritizes the use of electricity converted by the photovoltaic panel 571 and stored in the battery to power these components. At this point, indoor air enters the dehumidifier chamber 51 through the recovery air inlet 513 and is discharged outdoors through the recovery 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] For example, in another alternative embodiment, the specific form of the power storage component 572 is not fixed. Under the premise of being able to store electrical energy, those skilled in the art can adjust the specific form of the power storage component 572. For example, the power storage component 572 can also be a supercapacitor battery pack.

[0072] 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, a battery pack, a water collector 574, a water collection pipe 575, 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.

[0073] 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.

[0074] Example 3

[0075] 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.

[0076] like Figure 3 As shown, this embodiment differs from Embodiment 2 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.

[0077] Similarly, the water collecting pipe 575 can also be directly connected to the reduction water tank 53, so that the collected rainwater can be directly used to replenish the reduction water tank 53 for cooling.

[0078] Example 4

[0079] 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.

[0080] like Figure 4 As shown, this embodiment differs from Example 2 in that the solar controller 573 in the photovoltaic assembly 57 is directly connected to the dehumidification fan 515, the reduction fan 516, and the circulation pump 541 to power these components. This arrangement allows the power from the photovoltaic panel 571 and the battery pack to be directly supplied to the power-consuming components, reducing energy loss during the transmission process.

[0081] 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.

[0082] 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.

[0083] 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.
